Hello all, I have an Apricorn Velocity Duo x2 loaded with two 1 GB Samsung 850 Evos in a RAID 0 configuration, mounted in Slot 1 in a 3,1 (one of the two faster slots). They were formatted while in the Duo via Disk Utility. The speeds seem a little disappointing. Black magic reports about 660 read and write scores. I would have thought it would be around 800 or more. But worse, the subjective responsiveness is unremarkable or even quite poor. Loading a program seems reasonably fast, but when I open a folder containing a very large number of files (photos, etc.), the delay is enormous. It's very significantly slower than 2 older, slower SSD's that I have mounted in normal drive bays. It's so slow that I'd half expect even a hard disk to be faster. Something feels wrong, no? Any ideas? Thanks.
