Hello all. I am currently using the following: 4 x Intel 520, 3 x 1 TB WD Caviar Black and 1 x 2 TB WD caviar Black. I also have an original RevoDrive (which worked fine) but its gathering dust. I want to do RAID 1 or RAID 10 with the 4 SSD and may a RAID 1 with some of the Caviar Blacks. I was going to get a hardware RAID card (ATTO or Areca), but I am wondering whether I actually need it. Since I read Nanofrog's posts stating that MLCs are useless for parity, it seems like only RAID 1, 10 or 0 are possible anyway. Does anyone know whether AppleRaid allows a RAID 10?
