I'm looking to upgrade a server that I have. Right now, I have a Tyan P3 x 2 with 4 SCSI drives. I'm considering an upgrade to a Tyan K8SR S2881 G2NR or a K8SR S2881 UG2NR Opteron board. From what I have found, the difference is that the UG2NR supports SCSI drives and SATA. The G2NR only supports SATA drives. I've only used SCSi drives in the past. I guess that my question is whether or not the SATA drives alone will be sufficient for a server. I'm not familiar with SATA drives. Are they the wave of the future in the server market???
