My full setup is:

Intel Core i5-6600K @ 4.6Ghz
Thermalright TRUE Spirit 140 Rev. A
Asus Z170-A
G.Skill Ripjaws V Series 16GB (2 x 8GB) DDR4-2400
Sandisk Ultra II 960GB 2.5" SSD
EVGA GeForce GTX 980 Ti 6GB FTW ACX 2.0+
EVGA 750W 80+ B2 Bronze Certified Semi-Modular ATX

UserBenchmark shows my deep queue 4k read/writes as greatly underperforming: (Imgur)

FWIW here's what I get from AS SSD: (Imgur)

The result is reproducible. I've confirmed that TRIM is enabled and my SATA mode is AHCI. It's a brand new build, and my mobo drivers and SATA controller drivers are all up-to-date. Running Windows 10. And the drive is plugged into the port clearly labeled OS Drive: (Imgur)

Also, I realize that I probably won't notice this on a desktop that I'm not using as a workstation; still, should I be concerned?

Any help and/or thoughts are appreciated!
 
Hey there, hasuuu.

If you think that there might be anything wrong with the SSD, you should definitely backup your data, just to be on the safe side. After that go ahead and test it to see if any errors pop-up. Even though you're using a SATA port marked as "OS Drive", you should try the SSD with a different one and different cables. If there's an issue with booting to Windows, you should check the boot order from the boot priority menu in your BIOS/UEFI. It basically shouldn't matter which SATA port you are using, at all. Also, check if the SSD has any available firmware updates.

Hope that helps.

Good idea, I'll try changing the port and/or cable.


It's the UserBenchmark result that has me concerned. As far as I know AS SSD doesn't test deep queue speeds.
