WD Black M.2 SSD Slower that it should be.

[ben333]

Hi guys,

Just got a new M.2 WD Black SSD and it isn't as fast as it should be. My Sequential Read is about 1400 MB/s while the quoted spec is 2050 MB/s. I am running a brand new install of Windows 10 64 bit ( not activated yet ) and I have the 512 GB drive.

Any information to why this is happening and how to speed it up would be greatly appreciated!

Thanks!

What is your full system spec?

The quotes spec speeds are "up to", and would be in a perfect situation.

Are you quantifying what you currently have through a benchmark? Or file transfer?

What motherboard do you have this on? For example, if you're on Z97 (unlikely, I'd assume), there's only x2 not x4.

Remember, 'quoted speeds' are usually theoretical maximums. You will never reach those speeds in real-world usage.
M.2 drives are now getting fast enough to hit limits of other system components so your personal maximum will be different. The below review shows sequential read tests only hitting 867MB/s - you should feel lucky.

I tried CrystalDiskMark and the Samsumg Drive Benchmark tool. The board is a Z370 Extrene4 by AsRock

Would it make any difference which M.2 Slot I run the SSD in?

^^^ Did you see my post and check out that link? Your drive appears to be operating normally

Just about average
