OK, so lets say on my options, a

SCSI is the top 1
Raptor is 2
Sata is far below....

But regarding Macs, Internal RAID SATA2 on a mac, on my resarch are fast as WD Raptors... may be not in Latency and all OK.

But a XSERVE RAID, is like a very very good, nut has IDE drivers internally ? Or this is not that fast.

From what I read so far and researched, a ULTRA SCSI Card and 2 SCSI in RAID0, for HD movies looks a nice go.

What you guys think, and any recomendations on Brand and Kind, or any ULTRA 320 2 channels are OK, independent of brand - PCI-e

Thanks to all
