As the title states I have 2 Samsung 840 Pro SSD which are not reaching correct speeds. Below is a list of my system hardware configuration and speed results using AS SSD Benchmark. Please help me with this I have tried everything I can think of. I have updated all drivers, MoBo firmware, and still nothing. I have reinstalled my operating system using several different RAID 0 configs and continue to get similar results. So far RAID 0 64kbit stripe rate with read through and write back seems to work best, but still not seeing the speeds I should be. Any suggestions would be much appreciated.
