This testing is just to see what the drive is capable of in an FOB (Fresh Out of Box) state under optimal conditions. We are utilizing empty volumes of Windows 10 and Windows Server 2008 R2 64-bit for this testing. Same Hardware, just an OS change.
Windows 10 MOP
Samsung 850 EVO 4TB
Take a look at the massive difference in write transfer rates when compared to the 416 MB/s we got with Windows 10 build 10586. 555 MB/s is what we would expect when the transfer block fits inside the drives pSLC cache. If you needed a good reason to upgrade to Windows 10 build 14393, this is a good reason.
We have noticed a massive improvement in write transfer rates on many drives with build 14393. The reason for this, as far as we know, is that CPU power switching modes have been relaxed on the latest version of Windows 10.
Windows Server 2008 R2 MOP
Samsung 850 EVO 4TB
200 MB/s 4K QD1 random write performance is the rarest achievement you will ever see from a SATA SSD.
