Bought new 960 evo for boot drive, slow speeds

[TickleMyElmo]

Hi yall. So I bought a Samsung 960 Evo 250gb for my OS, main programs and WoW. Thing is, it is not performing at the speeds it's supposed to. I have included some pictures to help. I installed the drive in B) M.2_2 (SOCKET 3). Also included is the score I received from Samsung Magician. According to the specs the read speed is 3,200 MBps and write speed should be 1,800 MBps. I have it set up through PCIe 3x4. Is this normal, should I change some kind of settings, switch the slot, or just exchange it for a different one? I know nothing about M.2 so please bear with me here and help me out. Thanks guys..

First, make sure you have the latest Samsung NVMe drivers v2.2. Second, I have got goofy results from that Magician program before. Download CrystalDiskMark and run it. I'll post a copy of my Samsung 960 Pro which is a little faster, but somewhat comparable.

Not to be dour here but that looks right to me for a 250GB, most people look at the speeds for the 500 and not the 250. Assuming I'm wrong it's likely throttling which mean you'll need a heatsink like this:

no, the 250GB model is rated for 3200/1500 read/write. https://www.samsung.com/us/computin...ate-drives/ssd-960-evo-m-2-250gb-mz-v6e250bw/


The problem is the Samsung Magician program. Use Crystal Disk or ATTO to benchmark the drive. drive speeds vary depending on file size so you need a program to test relatively large files sizes (>1MB) to see the max speeds. I noticed the same behavior on my 960EVO when running magician vs ATTO.

also did you do a fresh install or just clone?? That may have a slight impact as well.

 

[gsrcrxsi]

i did a clone (windows image backup) from an 850 evo to my 960 evo. didn't matter. I still get full speeds.

now if you clone a HDD to an SSD, you might see some issues. but that can probably be remedied by running the drive optimization built into magician.

sorry was asking the OP about it. Yes alot of times it works fine if your staying with the rest of the gear being the same. But sometimes it can go wonky on ya. And if he didnt have the drivers on the old drive they're probably not on the new image.

 

[TickleMyElmo]

Fresh install. I'll get CDM and recheck scores. Oh and newest driver.

Use Crystal DIsk Mark, it is the benchmark we all use around here.

Easier for comparison

 

[TickleMyElmo]

Here are the Crystal Disk Mark results.

I also added another pic to the original post. Just making sure I installed them correctly with the right settings.

Similar to my results (with much higher for you for4k Q32T1). see thread: http://www.overclockers.com/forums/...they-seem-in-line-for-an-Evo-960-nVME-250gigs

Not sure I ever saw, was that a yes or no on updated Samsung NVMe drivers? The Windows drivers work, but the Samsung ones are faster. You can find them free to download on the Samsung website.

 

[TickleMyElmo]

Yes, I installed the latest drivers and my case has awesome airflow.

 

[gsrcrxsi]

Speeds look fine.

 

[batboy]

Good on the driver, one less thing to worry about.

 

[Nebulous]

Yup, looks good to me as well. Not every drive will be identical in reads/writes even if the systems are identical. Try using ATTO and you'll see a difference.

 

[gsrcrxsi]

+1 for ATTO. I really like it better as it tests lots of different file sizes and gives you a better look at overall performance.
