This post shows the baseline FOB raw peak performance of the Samsung 840 Basic which is installed in Testverse with Windows 2012R2. I used the “fio” (Flexible IO Tester) for this test. “fio” is my preferred tool to test SSD.
I make use of the Sample Windows “fio” job files. The specifications shows six metrics but I concentrate on (READ/WRITE bandwidth,Ran.READ/WRITE 4K). I tested with the job files:
- fio-job-04 = fio random 1M write peak BW
- fio-job-09 = fio random 1M read peak BW
- fio-job-010 = fio random 4K read peak IOPS
- fio-job-011 = fio random 4K write peak IOPS
Command line example:

set DISK=\\.\PhysicalDrive1 fio --output=job04.txt fio-job-09.ini |
Results:
fio-job-09 = fio random 1M read peak BW
