I have decided not to use them in RAID - the 900MB/s speed is overkill for me. I am now getting 480 MB/s Write and 520 MB/s Read on both drives (they are mounted internally on the Seritek 6G2+2 card). Before, I was getting a little over 100MB/s on internal Caviar Blacks. My question to you is the following: How best shall I set up the SSDs? (I have 2 1TB Samsung 850 PROS - named Wall-E and EVE) I have my System and Applications on Wall-E. At the moment EVE is empty. I've heard that it is best to store documents on a regular HDD, so have kept them on my Seagate SSHD. Is this correct? I was thinking of storing my most-used Kontakt and EXS instruments on EVE - relatively small files that won't be overwritten that often. Anyone have any other suggestions? There are so many similar posts - but not exactly like mine. Drives are RAIDed... Thanks for your patience. Peace!
