OCZ Revodrive X2 SSD Review

Add Your Comments

The OCZ Revodrive X2 isn’t your grandmother’s old hard drive. This thing uses a PCI-e slot with x4 bandwidth mode for extreme speeds in both write and read. OCZ sent over a 240 GB model that can read at up to 740 MB/s, write up to 720 MB/s, and perform up to 120,000 IOPS which are astounding numbers, especially compared to mechanical drives.

Specifications and Features

This was the first time I had held a PCI-e SSD in my hands and it gave me butterflies since I was so excited to see exactly how fast it is. When it first arrived, I couldn’t get the box opened fast enough. Getting a new toy to test always makes me revert to being a five year old on Christmas day, but this made me even more anxious than usual. Take a look at these stats:

100GB-160GB Max Performance 

  • Read: Up to 740 MB/s
  • Write: Up to 690 MB/s
  • Sustained Write: Up to 550 MB/s
  • Random Write 4KB (Aligned): 100,000 IOPS
220GB Max Performance 

  • Read: Up to 730 MB/s
  • Write: Up to 690 MB/s
  • Random Write 4KB (Aligned): 100,000 IOPS
240GB-960GB Max Performance (tested)

  • Sustained Write: Up to 600 MB/s
  • Random Write 4KB (Aligned): 120,000 IOPS
460GB Max Performance 

  • Read: Up to 730 MB/s
  • Write: Up to 700 MB/s
  • Random Write 4KB (Aligned): 120,000 IOPS

  • PCI-Express interface (x4)
  • For use as primary boot drive or data storage
  • 4 x SATA
  • Internal RAID 0
  • 181.07 (L) x 21.59 (W) x 125.08 mm (H)
  • Shock Resistance: 1500 g
  • Seek Time: 0.1 ms
  • Operating Temp: 0 °C ~ 70 °C
  • Storage Temp: -45 °C ~ 85 °C
  • Power Consumption: 4.3 W Idle, 8.3 W active
  • MTBF: 2,000,000 hours
  • 3-Year Warranty
  • Compatible with Windows XP 32/64, Vista 32/64, Windows 7 32/64

One thing to keep in mind if you are considering this drive is that not all motherboards will boot from the PCI-e slot.  Make sure you check the motherboard compatibility list to see if your board has been tested. For instance, the Biostar TP67XE would not recognize the drive at first, but Biostar has released an updated BIOS so that is fixed now.  Another thing to keep in mind is that the drive is designed to use a x4 PCI-e slot.  On a board that has three PCI-e slots, the last one might default to an x1 speed, like the Asus P8P67 Pro does.  You might be able to override this in the BIOS and force it to x4 mode in case your other two slots are taken up by GPUs. Otherwise, the card will work fine at x1 mode, which is still pretty fast but not optimal.

Another thing to keep in mind is that this SSD is really four drives in RAID, so Windows will need RAID drivers installed first to be able to recognize the drive. The drivers are available on OCZ’s website so you can either slip-stream them into your Windows disc for fresh installs or put them on some other media so you can load them before the Windows install process. When I was booting off my test HDD I had to install the drivers before I was able to run benchmarks on the drive.

Here is what forum member icebob had to say about doing a fresh install on the original Revodrive:

disconnect any other drive, disable any onboard raid controller,set sata to ide, go to ocz and load drivers (they don’t come with the drive!) and load both (32 and 64) on usb stick. install windows and when at the drive choosing page load 32 bits drivers first, even if you install 64 bits os and right after install the 64bits drivers after it should be peice of cake!

Test Setup

  • Intel i7 2600k processor
  • Asus P8P67 Pro motherboard
  • Zalman CNPS9900 heatsink
  • Patriot Sector 5 Viper II 2×2 GB @ DDR3-2133 c9 RAM

  • Windows 7 Ultimate 64-bit

For comparison, I’ll be using a standard Seagate 7200.11 1 TB mechanical HDD as well as the performance numbers Hokiealumnus got in his review of the OCZ Vertex 2 and the Patriot Inferno. He used a different system for his tests so the numbers are not 100% directly comparable, but they are still close enough to draw general conclusions about relative performance.

First up are the obligatory benchmark screen shots. Notice how the Revodrive X2 blows the mechanical HDD out of the water.

The most notable things here are that IOMeter confirmed the claim that the Revodrive X2 could do approximately 120,000 IOPS in the 4k Random Write test. This is due to OCZ’s proprietary SandForce firmware, similar to that on the Vertex 2. The ATTO Benchmark more or less confirmed OCZ’s claim that the Revodrive X2 had a maximum read of 740 MB/s and maximum write speed of 720 MB/s (I got 742 MB/s and 711 MB/s respectively). Comparatively, the OCZ Vertex 2 could do approximately 50,000 IOPS and 285 MB/s read.

While those are certainly impressive numbers, they don’t really correlate to real world use that well. Don’t worry though, because there is one test that will surely impress any computer user regardless of their tech level: Windows boot time.

You are seeing that correctly; the Revodrive X2 only took about 8 seconds to get into Windows while the mechanical Seagate 7200.11 close to 44 seconds. To get even more perspective on how fast that really is, the OCZ Vertex 2 and Patriot Inferno both booted Windows in around 20 seconds when Hokiealumnus tested them.

Conclusion

The OCZ Revodrive X2 certainly is the King of the Hill when it comes to consumer desktop drives. It soars above all other SSDs and HDDs. Simply put, this drive is amazing. Unfortunately, it costs a lot to be King and the 240 GB model is available at most retailers for around $570. While I could only see myself spending that kind of money in the case that I just won the lottery, this drive is more than worthy of being Overclockers Approved.
