Hey guys, I just got my new Samsung 840 Pro SSD and although the write speeds are good, I am geting less than 50% advertised in read speeds. I've been troubleshooting for hours now and can't get this drive to perform even close to its advertised speed.
I have a new Gigabyte GA-z87-oc board with 1 drive controller built in (6x Sata 3). I know that ACHI needs to be enabled for maximum performance but I also have to setup a RAID5 with 3 HDDs, of course using the same, sole controller on the MB.
So in my bios I have 3 options for the Drive controller: IDE, AHCI, and RAID. I set it to RAID.
I then unplugged all drives and plugged in the SSD making sure to use the SATA cable that came with new motherboard (labeled SATA 6Gb/s).
Installed Windows 8.1 got all updates and drivers. All is well. Also verified TRIM was active.
Then powered off and plugged in the 3 HDDs and did the Ctrl+I when prompted and setup my RAID 5. Got Windows to recognize the RAID5 setup so all looks good.
However, using Samsung's utility to test the SSD, I am getting very poor results. See screenshots.
Notice in it states AHCI Mode "Deactivated" and SATA Interface N/A.
Please tell me that I'm wrong when I make the assumption that for full SSD speed I need to go full AHCI and lose my RAID completely. Or stick with my RAID setup and get 50% performance reduction as a result with my SSD.
Thanks so much in advance for any assistance!
***Note, I decided to try to go back to AHCI to retest my SSD by itself but ended up with a bluescreen.
