Another Crucial M4 Slowdown

[ Edited ]

I bought my first Crucial M4 128gb ssd drive on 03/11/2011

 

Here is a test just after I bought it:

 

And here is a test from 13/09/2012

 

This above ssd was warranty exchanged for a new one.

 

This is a screenshot from 08/12/2012, after I received new ssd from warranty exchange:

 

And here is a screenshot from today 09/05/2013:


 

As you can see in both cases 4k-64thrd is cut in half after a few months time.

It's not like I do something extreme with this drives, I always have updated drivers/firmware, have trim on, never have any viruses etc, my ssd have like 32gb free disk space now.

 

My most important pc parts are:

 

i7-3770k@4.6ghz

16gb ram 1600

Asrock Z77 Extreme6

Asus GTX 670 DIRECT CU II TOP 2GB

CRUCIAL M4 SSD 128GB

2x SAMSUNG 1TB HD103SJ RAID0

SEASONIC X-760W

 

And yes ssd feels slower then I remember, windows loads slower. Do I really have to keep sending ssd for warranty exchange every few months now? Not only I lose my main drive for 2 weeks, but I have to rebuild my whole windows installation because of that, I use my pc a lot, and can't afford that to happen. I originally paid like 150 pounds for this drive, and didn't expect this kind of unreliability.

It seems to be normal behaviour I'm afraid after the drive has seen some use: http://forum.crucial.com/t5/Solid-State-Drives-SSD/low-4K-64Thrd-with-AS-SSD/td-p/84448

 

It won't affect real world performance as you won't see queue depths anywhere close to 64. You'll rarely see them much above 1.  Anvils benchmark at a queue depth of 4 is more realistic: http://www.guru3d.com/files_details/anvils_storage_utilities_download.html

Sorry, I'm using normal to mean common rather than expected.

 

I'm guessing you're a gamer from your system specs?  There's a pretty good article on it here: http://www.tomshardware.com/reviews/ssd-gaming-performance,2991.html  The vast majority of work occurs with a queue depth of 1.

 

By all means if you're not happy with the drive then please do contact Crucial support.  There just isn't a solution I know of that we can provide you with on here I'm sorry to say.
