I have a Samsung 850 EVO SSD and when I got it, my dual HDD RAID array was hooked up to the SATA 3 slots on my motherboard, so to get the OS installed and my data transferred over to it, I just plugged it into the SATA 2 slot. Now that my data is transferred, I wiped the HDDs and un-raided them. I then plugged the HDDs into the SATA 2 slots and the SSD into the SATA 3 slot. I went into the BIOS and changed my drives to run AHCI instead of IDE as well.
I was expecting to see some pretty good increase in performance from the Samsung Magician performance benchmark test when moving from SATA 2 @ 3Gb/s to the SATA 3 @ 6Gb/s but not quite.
SATA 2:
SATA 3:
Why is sequential read up but everything else down when I switched from SATA 2 to SATA 3?
Also, when it was plugged into the SATA 2 I did not set the OS Optimization. Once I plugged into the SATA 3, I had ran the OS Optimization for 'performance' and then ran the Performance Optimization prior to doing the performance benchmark. RAPID mode is off for both.
