seem to sell for no less than around 50 cents a Gig, occaissional sales in
the USA have PATA as low as 25 cents a Gig ie 160 Gig for 40bucks for a WD
from Best Buy.  The hottest gaming machines made which are the fastest
desktop PCs in existence, those in the $5000 and up category which usually
sport the AMD FX57 64bit processor btw, also tend to have 2 Raptors in raid
(for extreme speed) but because of their relatively small size availability
(max 74Gig) also have a 250-300 Gig storage drive, often the new Maxtors w/
16M cache, all SATA.  However these as you can see are
price-is-no-object,speed-is-everything PCs.  In gaming, lack of speed can
get you "killed" so even milliseconds count
, but I can't imagine that your needs are quite so intense, nor your purse
so cavalier, so I wouldn't rule out  PATA w/o first checking prices.

Thanks for the advice. This drive is purely for system image storage / 
transfer, not a gaming machine. I was interested how an Ultra SCSI drive 
could ba a SATA drive though ? Are you sure this isn't a SAS (Serial 
attached SCSI drive - which is different to SATA) ?

Prices here in Australia are around the same for SATA 1 and PATA 7200RPM 
drives, so I'll see what I can find at the computer fair today. The 
deciding factor is likely to be the suitability of an available PCI 
adapter card, rather than the drive in the first instance.

Cheers/2
