Crucial M4 low 4K-64Thrd

post #1 of 8
Thread Starter 
When I got my M4 last year this was the AS SSD score after installing the Intel RST drivers.

Today I ran another benchmark and my 4K-64Thrd is significantly lower. I am still using the same Intel drivers and I have not updated anything in my BIOS. This benchmark was after a clean install of Windows 7.

Both are on the same SSD firmware. What could be causing such a lower score?

Did you flash erase the SSD before the fresh installation of Wndows?

I read over at the Crucial forums around the middle of last year that they were having many many users reporting a degradation in 4K-64Thrd benchmark performance after a year or more of wear on their SSDs.

I don't think it ever got resolved though. Last I heard Crucial was looking into it.

I was having similar issues with one of my M4s and that is what sent me searching at the time. I've since retired my M4s, but kept my two C300s and replaced the M4s with another brand.

I noticed that a flash erase (secure erase with Parted Magic or HDDErase) helped a little bit, but it never did return to full "like new" speeds.

yea, happens to most if not all of them at some point.

Why? It doesn't affect normal usage patterns, only synthetic benches which mean almost nothing in real use. Typically a user will reach queue depths 1-5, the benches show degradation at ~queue depths 10-20 something, far higher than what you would usually ever reach.

My friend's m4 got a boost from a S/E too, but after a week or so the 4k-64thrd speeds dropped again. S/E is only a temp fix for benches.

Any fix for this guys? How long is Crucial's Replacement warranty again? Are they offering replacements for this particular issue?
post #6 of 8
There is no fix and you can R.M.A. it if you want.BUT you will see same problem in two weeks.I say this because i saw on Crucial forum guy that R.M.A. it three times and every time problem comes back.
I suspect that they not send completely new drive from factory ,just from somebody else secure erase drive with reset smart readings.
Just forget.
I also suggest you to install "Intel RST" driver for better responsiveness of system.

Rakin,

Install Intel RST (rapid storage technology) drivers for best performance.

Also, I wouldn't worry about 4K-64 values. Typical consumer usage patterns for SSDs never exceed more than 10 queue depth, except possibly during startup (and even then it is somewhat unlikely). This is because SSDs fulfill read requests at such a rapid pace that queue depths stay low (1-5).

Tried it, no difference in score. I guess I can live with this. redface.gif
