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,

We would like to perform some tests here in our lab about this results you have. Please allow us some time to double check all settings, the important step was to install the NVMe driver from us.

If you have any news about this please let us know as well.

Any update? Should I start an RMA?

Silonaz,

We have had no freezing up issues, what software are you using to measure the read speed?

For you to be aware we advertise the sequential read/write using IOmeter* as you may find in the following link: http://www.intel.com/content/www/us/en/solid-state-drives/ssd-750-brief.html Intel® Solid-State Drive 750 Series Product Brief

Please let us know if you can test it using IOmeter* (With queue depth 32).

I used Aida64 and Crystaldiskmark as shown in the image I linked. I have tried Iometer but it stalls on 'Preparing disks...'

EDIT: It's running, but very slowly. Test has been going nearly half an hour now.

EDIT2: Been running for hours now, surely this isn't normal.
