Hi, > I had tried to configure the first SAS HD as RAID 0 before. The RAID 0 > SAS HD was also > recognized as SCSI-0 device. I am a bit puzzled. How can you configure ONE disk in RAID. AFAIK, any RAID configuration needs a minimum of two disks. > I think the problem is not on the size of RAID 5 HD. I never mentionned anything about the size, I just said that inherently, RAID 5 has slow transfer. If you need faster transfer, you may think about a different RAID architecture. Best regards, Olivier
