HighPoint RocketCache 3240X8 Review

Today, we have a product from a company typically associated with the server and business market, HighPoint Technologies, Inc. HighPoint has been around since 1995, so they have been in the storage segment for around 17 years. I’d say they are most well known for their RAID host bus adapters (HBA), but they also make storage enclosures, various expansion devices, and storage management solutions. What we’ll be taking a look at in this article is HighPoint’s RocketCache 3240X8; a product for combining multiple SSDs and HDDs into high performance, high capacity storage solutions.

HighPoint RocketCache 3240X8

As you can can see from the print on the PCB, it’s pretty obvious that HighPoint’s RocketCache uses the same PCB as their RocketRAID 2720/2710 cards. Particularly, the 2710 since there is only one SAS port on this card. In fact, the only difference in the two is their firmware.

After looking at the PCB, I’m sure a few of you are looking at the empty SAS port spot and wondering. Before you start thinking to much about soldering another connector onto the PCB, let me go ahead and tell you that it won’t work with the firmware installed on the card. So, it won’t be that easy to get four more drives connected to the RocketCache.

Installation & Setup

Physical installation of the RocketCache was very easy; it’s installed just like a typical GPU or other PCIe card. Once it’s in the system, a RocketCache BIOS splash screen will appear during boot to let you know that it’s installed correctly and being recognized by the system. When the OS loads, the drivers and software can be installed from the included driver CD.

Caching Modes

Max Performance

1+ HDDs and 1+ SSDs

This caching mode optimizes the SSD and HDD devices for maximum read and write performance.

When using more than one SSD in this mode, they are set up similar to a RAID0 as far as performance goes. Multiple HDDs are combined for more storage space and they’re reliant on one another for data access. So, if one of the hard drives dies, then all data will be lost.

High Performance with Cache Protection

1+ HDDs and 1+ SSDs

This caching mode combines ultra-fast data access with write protection. Your cache files are written directly to disk.

Multiple HDDs are combined for more storage space and they’re reliant on one another for data access. So, if one of the hard drives dies, then all data will be lost.

High Protection and Cache Performance

2+ HDDs and 1+ SSDs

This mode provides high-level of data protection with improved access speeds. Multiple copies of each file are permanently stored on the hard disks.

Data is written to the SSD cache, then moved to the hard drives when the system is idle. Hard drives are mirrored in this configuration, and SSDs are used as general cache.

Max Protection

2+ HDDs and 1+ SSDs

This caching mode provides the maximum data protection. Multiple copies of each file are written directly to disk.

Data is written directly to the hard drives, then frequently used data is moved to the SSD cache. Hard drives are mirrored in this configuration, either 2-way or 3-way mirroring.

Web-based Management Software

When you install the management software from the CD, it places a “RC” shortcut on the desktop that opens up a web browser taking you to http://localhost:7402.

The first thing to do when in the web-management software is to initialize the drives connected to the RocketCache. This can be done on the Overview Tab by clicking on Initialize Devices. Once the drives have been initialized they can be combined into a single drive.

Overview Tab

Overview Tab

To create a RocketCache drive go to the Build RocketCache tab, select the caching mode desired, choose which drives to be used, and then click Create to create the drive. A popup should appear to that says the drive has been created, or it will show an error if the selected cache mode and number of drives selected are incompatible. The newly created RocketCache drive will appear at top of the Overview tab as well. The More Information button shows the RocketCache drive’s name, cache mode, capacity, cache policy, cache size, and status.

Build RocketCache Tab

In the management tab, there are quite a few things that can be done. Remove Cache will remove the SSD cache relationship from the RocketCache drive. The Maintenance link allows the RocketCache to be deleted or unplugged. If the RocketCache is configured in a mirroring mode, then there will be an option to rebuild.

If something happens to the system during SSD caching that causes it not to finish, then the Status will read Disabled instead of Normal. then, as long as the RocketCache is not configured as Max/High Performance, the cache data can be recovered by using the Recover option in the Maintenance link.

Before the newly created drive can be used, it needs to be formatted like any other partition by going to Disk Management in Windows. You can also see the SSD space left over from creating the cache for the RocketCache drive, which can be used as storage so it’s not wasted space. One downside would be if the cache and SSD storage are being accessed simultaneously, then the performance of both would be affected.

General Usability

The on-board speaker does its job well. I was unfortunate enough to be able to experience it unintentionally when one of my three hard drives decided to bite the dust during testing. I was across the house when I noticed a constant, high-pitch ring and it turned out to be one of my drives. My test setup is on an open bench, which definitely helped me hear the alarm.

The heatsink on the RocketCache definitely gets hot around 58-59 °C, so I’m sure it wouldn’t mind some airflow. I kept a Scythe Gentle Typhoon AP-15 pointed in its direction throughout testing which kept it around 37-38 °C.

Highpoint’s RocketCache was easy to setup and configure, but there are a few things I noticed that were odd or annoying:

  • When using one or two 256 GB Vertex 4 drives, the cache created by the RocketCache will be 68 GB and it’s not configurable, whereas cache size is configurable with Intel Smart Response Technology. Highpoint responded saying “A cache size beyond this limit offers no performance benefit. Future versions may provide additional options/settings for larger SSD’s.” However, as I mentioned earlier, the leftover SSD space can be used as storage, so it’s not wasted.
  • The RocketCache is not a bootable device, so no running an OS off the RocketCache drive. However, Intel’s Smart Response Technology can be used on the system drive.
  • Only one RocketCache drive can be created at a time, so having two separate 1 SSD + 1 HDD configurations is not an option.
  • Whenever a RocketCache drive is accessed after waking the PC from Sleep/Hibernation the driver (rc32xx) crashes, causes a BSoD, and the PC reboots.

OCZ Vertex 4

(Product Page at OCZ’s Website)

The two Vertex 4 SSDs were kindly provided by OCZ for the testing of the RocketCache 3240X8. Something to keep in mind when looking through the RocketCache results are the rated specifications of the 256 GB Vertex 4:  560 MB/s sequential reads and 510 MB/s sequential writes. I’ll be supplying Vertex 4 results for this article, but be sure to check out our 256 GB OCZ Vertex 4 Review by hokiealumnus for a much more thorough look at the Vertex 4 itself.

Methodology

Since I have two OCZ Vertex 4 drives and two Samsung Spinpoint F3 drives for testing, that leaves me with the following configurations to test. I had three hard drives initially, but one of them died during testing so I can’t provide 1 SSD + 3 HDD results, unfortunately. Two of the modes require at least two HDDs for mirroring, so those cannot be set up for single HDD configurations.

Test Configurations 1 SSD 2 SSD 1 SSD + 1 HDD 1 SSD + 2 HDD 2 SSD + 1 HDD 2 SSD + 2 HDD
RAID0 N/A N/A N/A N/A
Max Performance N/A N/A
High Perf w/ Cache Pro N/A N/A
High Pro & Cache Perf N/A N/A N/A N/A
Max Protection N/A N/A N/A N/A

The following are the programs and their settings used to test the RocketCache for each configuration and cache mode. Each test was run three times for each config and each cache mode to check for any noticeable performance differences. That comes out to be around 266 benchmark runs.

  • Max disk size: 16,000,000 sectors
  • Starting sector: 1024
  • Queue Depth: 32
  • 2 MB Sequential Read/Write; Sector Aligned
  • 4 KB Random Read/Write; 4 KB Aligned

Performance Results

OCZ Vertex 4 Baseline

The hard numbers can be found here.

First we should probably look at some baseline results so we have something to compare to when checking out the RocketCache results. The following are single drives and RAID0 results of the Vertex 4 drives using the on-board RAID of the Maximus V Gene. We can compare these to the RocketCache configurations to see how close they get to straight SSD performance.

ATTO

The hard numbers for ATTO are here.

ATTO is the test I like to run to see the maximum potential of drives. “Max Performance” and “High Protection and Cache Performance” are the best performing cache modes with the latter actually coming out on top in both reads and writes. So, Max Performance isn’t really what its name suggests, but it does provide twice the storage space of the High Protection and Cache Performance mode. As for the other two modes, High Performance with Cache Protection and Max Protection, they have slower write speeds since data is written to the HDD(s). Surprisingly, the Max Protection mode has top tier read speeds as well, but it’s by far the slowest in writes. High Performance with Cache Protection has the slowest reads of any of the cache modes and about twice the write speed of the Max Protection mode while providing twice the storage space.

Comparing the earlier Vertex 4 RAID0 results with the 2x SSD configurations of the RocketCache, we can see the the RocketCache provides performance exceeding onboard RAID0 in some cases. This performance increase most definitely comes from HighPoint’s experience in designing RAID controller cards. However, the single SSD RocketCache configurations don’t quite perform as well as a Vertex 4 on the Intel SATAIII controller.

Something odd I noticed is when adding the second HDD, the read speeds decreased and the write speeds increased. The reads dropped significantly in the High Performance with Cache Protection mode when going from 1 SSD + 1 HDD to 1 SSD + 2 HDD (greater than 100 MB/s loss) and when going from 2 SSD + 1 HDD to 2 SSD + 2 HDD (greater than ~400 MB/s loss). This means that the 1 SSD + 2 HDD and 2 SSD + 2 HDD modes perform about the same in ATTO when in High Performance with Cache Protection. This really makes me wish that my third HDD didn’t die, so I could see if adding a third HDD would reduce the speeds even further. I’ll definitely be looking out for changes in performance between number of HDDs used in the other tests as well.

IOMeter

The IOMeter hard numbers are here.

Not quite as many graphs here in the IOMeter section since the data can be grouped better without causing clutter. Again, the best performing cache modes are Max Performance and High Protection and Cache Performance. All of the caching modes had trouble with the 4 KB Random Reads, but when we look back at the Vertex 4 results, the numbers are quite the opposite. So, the Intel SATAIII controller did much better than the RocketCache in the IOMeter 4 KB reads and writes.

We don’t see the performance drop in IOMeter when going from 1 SSD + 1 HDD to 1 SSD + 2 HDD in High Performance with Cache Protection as we did with ATTO. However, there is a drop when adding a HDD to the 2 SSD setup in IOMeter, a ~100 MB/s or so drop.

1 SSD + 2 HDD Performance

CrystalDiskMark

CrystalDiskMark numbers can be found here.

In CrystalDiskMark, the numbers are quite a bit different than the ATTO and IOMeter results. The write speeds are faster than the reads in all the configurations and sub-tests. When looking at these results it looks like I may have flipped the reads and writes around in the graphs by accident, but I did not. I double and triple checked this. The Seq and 512 KB writes in CrystalDiskMark with the RocketCache with 1 SSD are ~100 MB/s lower than the Vertex 4 results, and the reads are just a little lower (about the same really). The RocketCache 2 SSD configuration results are a complete 180 of the 1 SSD configurations. The Seq and 512 KB writes are ~100 MB/s faster than the Vertex 4 results, and the reads match the baseline.

The best overall performing cache modes are still Max Performance and High Protection and Cache Performance. However, the highest read speeds go the Max Protection and Cache Protection modes, oddly enough. Again, reads go down and writes go up in most of the results when adding an additional HDD.

1 SSD + 1 HDD Read Performance

2 SSD + 2 HDD Read Performance

2 SSD + 2 HDD Read Performance

2 SSD + 2 HDD Write Performance

2 SSD + 2 HDD Write Performance

AS SSD

Hard numbers for the AS SSD tests are here.

The first thing you’ll probably notice with AS SSD is that the 4 KB numbers are pretty much non-existent outside of the writes in the Max Performance and Cache Performance modes, and definitely not as good as the Vertex 4 drives alone. The best overall performing modes haven’t changed and are still the Max Performance and High Protection and Cache Performance modes, with the latter leading the charge. The performance change by adding a HDD appears in AS SSD as well with reads decreasing a little or remaining constant and writes increasing. However, initial read speeds are higher than straight Vertex 4 speeds, so the drop to read speed results in performance still higher than a Vertex 4 on the Intel SATAIII controller.

Conclusion

The HighPoint RocketCache allows end users to have SSD-like transfer rates while having the large capacity of traditional HDDs. The RocketCache is unique because of its ability to use multiple SSDs to get cache performance similar to RAID0 SSDs, and allow mirroring of data across multiple HDDs.

High Protection and Cache Performance mode is the best performing cache mode. Not only does that mode perform the best, it also mirrors your data for security. However, the Max Performance mode is the best mix of performance and storage space, just be aware that if a single HDD fails all the data will be lost (much like RAID0). The other two modes, High Performance with Cache Protection and Max Protection, are still good performance-wise being much better than a HDD alone, especially in reads.

Typically, read speeds stay the same or decrease some when adding a HDD, while write speeds increase. So, there is a sacrifice for doubling the storage or mirroring data, but it could be well worth it depending on the usage.

The con that could be considered a deal breaker for some people is the driver crash issue when using sleep mode. Hopefully, this issue will be able to be fixed with a BIOS/firmware update from HighPoint. Personally, I don’t use sleep mode anymore since I started using SSDs as boot drives. My gripes about the RocketCache are listed below, but aren’t deal breakers for me.

  • Not a bootable device
  • Having multiple RocketCache logical drives is not an option
  • rc32xx driver crashing after waking the PC from sleep requires the user to turn off sleep mode altogether to avoid blue screens
  • An option for RAID5-like parity for the 1 SSD + 3 HDD would be nice instead of just triple mirroring to give the user more storage space while still being protected from a single drive failure.

The RocketCache 3240×8 is selling for $160 at NewEgg and 60/64 GB SSDs can be had for around $65. So, if you need both high capacity and high speed storage, the RocketCache will be much cheaper than the equivalent amount of SSD space and easily outperform mechanical HDDs. However, for the everyday user, it would be more economical to get a larger SSD and maybe an external HDD since the majority of users don’t need or use a ton of space in day to day use.

Overall, the HighPoint RocketCache is a unique solution for hard drive caching that does what it was designed to do and does it well; which is exactly why we award Approved stamps.

  1. have to let some that know more than i explain.

    but you can get the same perfomance but probably much better depending what raid config you use...of course more $
    Thanks Boucher,

    Excusing my ignorance on this matter, how would a SAS controller increase performance versus a PCI-E card like this.

    If the PCI-E provides 6GBps throughput (I think that is correct) is that not reaching theoretical bus limitations?

    Or have I got completely the wrong end of the stick on this one?
    Personally, I've never run a VM before, so I'm unaware of the requirements you would need. With the RocketCache you get SSD-like IOPS with HDD capacity. The IOMeter data has 2MB Sequential and 4KB Random IOPS numbers for 1xSSD, 2xSSD RAID0, 1xSSD caching, and 2xSSD caching. Of course, the smaller the files the better the IOPS.
    Would this be of suitable use to someone wanting host a few VMs ?

    I want to set up a test lab, partly to complete VCP certification and partly to emulate a server environment.

    IOPS are usually the critical impeding factor.

    Would the increase offered by this product be enough to sustain a few vms?

    As I have the need to simulate ESX hosts and have multiple vm's on the go, including upgrade and patching scenario's, I need more space than what a single SSD can offer. Using 1 or 2 TB HD with SSD caching sounds interesting, but will it give me enough IOPS ?

    Advice appreciated.

    I had no idea Highpoint had a bad rep... interesting (happen to have any links so I can read up?)

    Along those lines, a good backup policy is CRITICAL to have for a single drive or any other setup for that matter......mitigating any risk supposedly incurred by using Highpoint's products, no?


    In my experience their UDMA 66 and 133 controllers were prone to nuking drives. We had many an irate customer with Abit mobos that had these controllers on them.

    As for backups, yes, the data is saved, but you still waste time.

    I don't see the point of this product. It is simply Intel's Rapid Response on steroids, however, with HighPoint's reputation I would not trust my data to this product.

    We need OS/software level support for tiering, similar to the new Fusion Drive option on OS X.

    I think that I just fail to see the purpose of a product like this. I think the thought process behind it has potential but the end result is clumsy and possibly not worth the cost.

    The alternative of using a SSD (or two for mirror/backup) for your OS and a Raid 1/5/10 for your storage just seems like not only a safer/better, but more cost effective solution.


    The RocketCache is for people who need fast transfers on all their storage without breaking the bank. Using a SSD for the OS and HDDs for storage isn't a bad solution at all. However, only data on the SSD will be fast, whereas with the RocketCache, any data you have stored and use often will be fast. For example, if you happen to change what data you access from week to week, then it will all have fast transfers using SSD cache. If you are constantly creating data and want to have fast transfers with that data, then a SSD will fill up much faster than SSD cached HDDs when saving the data.

    djscrew
    With the cost of SSDs steadily dropping, you would be better off with spending the $160 in that much more space on a SSD and pick up a HDD as well. With that you get more GB/$ and also less links in the chain to fail.

    Just my 2 c ;P


    I actually said the above in the conclusion :DAn eSATA/USB3 external or internal HDD would work best.

    what about seek times? my raptors in raid zero spit out good numbers, seek times are not the best."


    There are access times (ms) in the AS SSD table, I didn't want to add more graphs when there's already over 30 in the article. I have the hard numbers linked at the beginning of each section. What do your Raptor access times look like?

    I'll also throw this out there showing costs, "best case" speeds (RAID0 or cache performance modes), and performance/$ and assuming someone wants 4TB of storage.

    Getting 4TB of SSD space is out of the picture due to cost, plus you would probably need a RAID card to get support for 8 drives in RAID. I guess you could just span them across each other to avoid buying an HBA, it would just cut the speed down to 550MB/s, making SSDs-only even less worth it. So, to get affordable high speed, high capacity storage, RAID arrays or SSD caching is required. For single SSD caching, ISRT may be a better choice if your motherboard supports it just because of the "no extra cost" to the end user. I'll be testing ISRT soon to find out, as long as I can get the software working.

    It seems overly complicated and poorly programmed. It's modes are also kind of stupid and misleading and their benefits seem somewhat ill conceived.


    Cache is set up the same on the following modes, so performance is similar with fast reads and writes.



    • Max Performance: SSD RAID0 Read/Write + Combine HDD Storage

    • High Protection and Cache Performance: SSD RAID0 Read/Write + Mirrored HDDs; Data is written to cache first, then moved to HDD when idle. So, you get faster writes.



    Cache is set up the same on the following modes, so performance is similar with fast reads from SSD and slower writing to the HDD.



    • High Performance with Cache Protection: SSD RAID0 Reads + Combined HDD Storage; Data is written to the HDD first, then moved to cache. So writes aren't as fast.

    • Max Protection: SSD RAID0 Reads + Mirrored HDDs; Data is written to the HDDs first, then moved to cache. So writes aren't as fast.

    They should give you independent control over each array of HDDs and SSDs.


    There can only be one array on the RocketCache, and you have control over it. Am I missing something on this? Maybe I'm not understanding what you mean.

    djscrew
    Not giving any option for raid 5/10 style parity is dumb as well.


    djscrew
    I was initially excited about this product because I am looking for something like this for my server that has limited motherboard drive space. But after reading the review it seems like they need to go back to the drawing board and come back with a real product. IT should be more like a super fancy raid controller card then a bloated and confused hybrid ssd/hd disk.


    djscrew
    This part makes it also seem a bit underwhelming for the price:

    From the last 3 quotes, you are definitely looking for a RAID card and the RocketCache is not one. The HighPoint RocketRAID 2720 costs the same $160, supports up to 8 drives, and has RAID 0/1/5/6/10/50/JBOD. However, you won't get close to the speeds that the RocketCache can provide unless you RAID0 4, 8, or 12 HDDs. The RocketCache at least has protection from a single drive failure when in the Protection modes. So, HighPoint made a compromise. They sacrifice a SAS port and RAID 5/6/10/50/JBOD features for greatly increased speed. It depends on what the end user is looking for.

    HighPoint may very well combine the RocketCache with one of their RAID cards to have the best of both worlds, having SSD caching RAID arrays; which sounds awesome, but it won't be cheap.

    I don't ever sleep mine except by accident. Sleep drives me nuts.


    Sleep could and should probably be abolished considering what Intel is doing with hazzy and the power features they're building into it...

    Old MS users know to distrust hibernate and sleep ... but i wonder how much they've improved for win 7 and 8.

    eh probably not much...
    I dunno ... I gotta say that it looks like junk to me. Especially for $160!:eek:

    Not giving any option for raid 5/10 style parity is dumb as well.

    I was initially excited about this product because I am looking for something like this for my server that has limited motherboard drive space. But after reading the review it seems like they need to go back to the drawing board and come back with a real product. IT should be more like a super fancy raid controller card then a bloated and confused hybrid ssd/hd disk.

    This part makes it also seem a bit underwhelming for the price:
    Also, with a SSD as a boot device, boot time is significantly faster. So, when you can go from off to desktop really fast, that makes Sleep mode pointless.

    The Sleep issue with the RocketCache still needs to be fixed, don't get me wrong. It's just not a deal breaker.

    If it wasn't able to be bypassed then I would consider that a fail.


    Yes, if Sleep couldn't be disabled, it would have definitely gotten a Fail since it wouldn't be usable at all.
