If you think Raptors are expensive for the performance improvement you get,
wait till you get prices on 15K SCSI drives of the same capacity especially
considering that you need to add the cost of a good SCSI card.

Er, any SAS drive will work when plugged into a SATA interface. You won't
get the full 600MBps of the SAS interface but as that is only the burst
transfer speed from the cache I would not worry to much, as no drive in
existence can sustain even 150MBps of SATA-I

However for reference a Seagate Cheetah 15K.5 300GB 15k RPM SAS drive will
set you back a whopping £550+VAT, the equivalent SATA drive from Seagate
is less than one tenth the price. It is also more noisy when idling than
the SATA drive when seeking by some 0.6bels.

The performance is awesome, but trust me, it is something you put in a
sound proofed, air conditioned server room that you only enter briefly as
infrequently as possible.

I wouldn't go that far, but it's true the .5's and 4's are noisier
than the .3's.
 
So 'SERIAL ATTACHED SCSI' drive can be plugged straight into a SATA2 port ?
Yes ?
What would the O/S driver see though ?..just like a SATA or would it need
special SCSI driver ?
The fact I have never seen any reference to such a set-up presumably means
it can't
work & or makes no practical sense.
This 300 Gig one looks like it might go for UK £100

I'm the O' Poster ...lots of useful comments ...looks like I'd best go back
to day dreams of
solid state 'Drives' for a few more years.

I'm becoming increasingly aware of speed limitations with standard SATA2
hard drives I have.
looked at the Raptor Drives ...far to expensive for the little
improvement Re.
standard SATA2 .

If you don't want to pay for Raptors, you don't want to pay for SCSI.
