 Posted: Mon May 07, 2007 11:23 pm Post subject: SCSI Hard Drives for Home comp ?? |
 |
|
With my newly put together Home Computer ...games , general purpose use, C2D
E6600 @ 3.2 Gig, Geforce 8800 ...Win XP or VISTA.
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 .
I really don't like the prospect of RAID...I would need at least 2
identical drives with a reduction
in reliability (2 rather than 1 thing to go wrong) ...to get RAID speed
improvement with a
good level of error protection I would need SERIAL ATTACHED SCSI3 or more
drives ...all to complicated .
SOOO ! what about SCSI Hard drives ...I see Rpm's of 15000 ..access times
less than 1/2
that of standard SATA2 ..the only way it could into go in my system is
(presumably)
with a controller card into the standard PCI slots (33 MHz) ...does that
have the speed ??.
Orthough there is now something called 'SERIAL ATTACHED SCSI'
I don't seem to see this approached ever mentioned in connection to IBM PC
comp. Home computers
so I guess the answer is NO !!
Some one want to tell why ?

How about 4 cheap disks in a RAID0+1 configuration. Double the effective
transfer speed, plus redundancy. Probably still cheaper than top of the
line 15k RPM SCSI disks + controller.
Do it in software, no need for fancy cards for that.
Cheers

It depends how one prioritizes. Personally I hate drive failures,
and have been running the same set of four Seagate 15K.3
drives for almost five years now. They're built like tanks, run
at 30C at load and are virtually silent. My Adaptec 39320
controller cost $60 from eBay.

If you're serious, consider the cost of a SCSI Raid adapter for your PC in
addition to the cost of the SCSI drives, which at the 15k rpm level come in
capacities far smaller that what's available in SATA drives these days for
the same cost.
For a home PC that you're describing as 'general purpose use', going to 15k
rpm SCSI is overkill unless you have plenty of money to throw at it for the
performance gain you would get.
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.
If you want spped and safety, you can always consider a RAID 5 array or a
RAID 10 array.

Correct me if I'm wrong but I've always thought the speed advantage of |
SCSI came into play when more than several un-RAID'ed disks were
attached to a controller and multiple users were all trying to access
data at the same time. Conversely, 1 SCSI disk vs. a similarly rated
IDE, SATA, disk etc. had little speed advantage when only 1 person was
reading or writing. Slower SCSI disks with an appropriate controller
could outperform very fast SATA disks in a typical server environment,
though that might not be true in a desktop 1 user PC. |
