Raid 0 works better if the SSDs are identical (same size and same write and read speeds) and if possible, start it with the drives blank/formatted. Raid controllers use SATA and SAS drives in most cases. You might want to consult the Chipsets Forums for more information on Intel® Rapid Storage Technology.
Hi but the P3608 made of 2 identical drives
