Hi all
there's a good article on serial ATA on
http://www6.tomshardware.com/storage/20 ... index.html
150 MByte/s maximum transfer rate (300/600 MByte/s envisioned for the future!!)
but bottom line is it's not worth upgrading yet as it's got some more development to go

That guides a little dated - Serial ATA is pretty good right now. The first models out were generally standard Parrellel ATA drives with a chip that added the capabilities of the S-ATA interface but with no major performance improvements. They generally ran at 100m/b p. sec.
If anyones serious about pulling DV / Uncompressed clips off their PCs the Western Digital Raptor is the way to go - in tests they generally out preform even top end SCSI Drives and are half the price.
A 36Gb Raptor costs about the same as a 120gb P-ATA and about 25% of a 36gb SCSI. Anyway the review below says it all:

We're looking at having at least one of these drives before new years so expect a review on VJcentral some point soon.

also, do you know if it's necessary to have all serial ATA drives to get optimum performance?
I have heard mixing serialATA and ATA drives will slow the serial down?

Maybe... we just got a S-ATA Seagate Barracuda 120gb (7,200 w/ 8mb Cache) and have a couple of indentical P-ATA models. Our plan will be to run a standard P-ATA OS Drive and a S-ATA for clips...
Some point next week I'll give them a speed tests on the drives and post them here.

I run a Raptor drive (they're only available in 36gb now, but look for a ~75gb out soon) and yes, it rules.
Other than the raptor drive, there are no SATA drives worth upgrading / purchasing.
There is *no* benifit to using any other sata drive for resolume. The raptor also has a 5yr warranty - nice feature as most drives ship with 1yr.
Sure "150 MByte/s maximum transfer rate" sounds great on paper, but that's a "theoretical maximum" realistically there is _no benifit_ for sata. Just check the drives sustained transfer rate (use a program like hdtach to tell the difference) The raptor really is amazing, all other drives are not.
Yikes... maybe Western Digital should hire me as a product rep.

Yup, the Raptors are the biz - used ours over the weekend and it handled pretty much all we could throw at it.
