Intel 750 stability and speed

[DRich20]

Have had ssd for half a year now but in the last few months system has at times frozen at times of write activity, such as windows start and restarting. I took it out of system last week and tried another hdd which also froze after some hours so I thought that was that.

When resuming from sleep today the system froze after a minute and while an application was launching. Interestingly when I rebooted the application configuration has been wiped. I have asked about the drive also not showing SMART data but have had no response yet, today I also decided to run a speed test and for read I get a maximum of 800MB/s which is way below what it should be. When I first installed the drive last year (in the same system) it was getting the full 2000+ speed.

My system:

Intel 750 2.5" 400GB

ASRock x99itx/ac with asrock u2 to m2 adaptor in m2 slot for ssd

Windows 10 x64

Xeon haswell e

EDIT: Added images and now installed intel nvme driver which allows toolbox to run optimizer. No change and had one freeze on boot since:

Silonaz,

If you are testing IOmeter, it should give you the sequential read or write depending on the test, could you please share some screenshots?

I stopped the test as I didn't want to leave pc on all day. Can you give me instructions on how to perform a shorter test? Other benchmarking apps take minutes, not hours. There was no estimated speed in the results, also task manager showed the ssd only operating at an average of 240MB/s so I didn't think the test was utilising the drive properly.

This is taking a while and I can't use this unstable pc much longer. I am considering borrowing an m2 card from another pc, but this would be a painful process with cloning that system onto another drive and possibly a new OS install or a clone on this one. Would talking to customer support be a step forward or can we use some program besides Iometer which would get the results today.

Maybe this data of a properly working Intel 750 400GB can help demonstrate that my results are not normal.

This test was run at the same configuration as the one I posted above:

To save you scrolling up, here is mine:

As you can see, all readings are lower on mine, some of them significantly.
