I went the SCSI route for a dev workstation, using SCSI raid & 15K RPM
Cheetahs. I ended up reverting to SATA 10K RPM system discs. I found that
the SCSI command queuing optimisation actually degraded performance for the
workstation application - its really much better for server type loads where
the queue of requests is long, and the time taken to optimise it for best
head movement is worth it. I also had heat and noise problems with the 15K
discs. Additionally, the theoretical higher throughput of SCSI is limited by
the PCI bus bandwidth, so unless you have multiple PCI's you don't get much
benefit from the SCSI bandwidth.
The SCSI discs and controllers are expensive, and have little resale value.
The SATA discs are relatively inexpensive, and lots of Motherboards have on
board support for SATA raid.
I built my machine to host multiple Vmware images for testing messaging
systems & I used a supermicro board with 2 x XEONs to get adequate
performance for my multiple ( 4- 5 ) Vmware images. The new Intel quad core
processors are very affordable & coupled with SATA Raid give adequate
performance for this sort of development setup at a good price.
That said a used server (say 2 x XEON based) with multiple PCI's might be
economical if you can find one, and you are determined to try the SCSI
route. I won't do it again.

I'm a developer using XP Pro for developing business apps with Visual
Studio.NET and SQL Server.
My current workstation is a few years old and uses a single IDE drive. I'm
looking to build a new workstation. I plan to NOT install Vista and
continue using XP Pro for the foreseeable future.
My question:
What would you recommend for the hard drive(s) on my new workstation? I
ask because several years ago I saw a number of friends have nothing but
trouble with SATA (they were early adopters of SATA and had compatability
problems with their mother boards), but it appears that SATA is now
well-established and stable and therefore a better option than IDE. But
what about SCSI? Is that a better option than SATA if I'm going after
all-out performance? I would like to be able to configure the drives as
RAID-3 (stripe).
Thanks.
