Everyone's experiences are different. I purchased 4 brand new Seagate
750g SATA drievs and put then in an Infrant ReadyNAS 1000. Within 1 week of
being online, I had SMART errors on a drive and it needed to be replaced.
The only thing that drive actually ever did was have to go through the
initial RAID5 built,. and transferring of about 200g if data.
I've had plenty of SCSI drives fail, but nothing THAT fast. Curiously,
I've yet to have a Seagate SCSI drive fail in my Dell servers. But I've had
Quantum, Maxtor, WDC, and Fujitsu all fail. Interesting, eh?
I'm of the opinion that SCSI drives are built to higher standards. I have
no substantiated proof of this except my own personal experiences.
That being said, we are using SATA for inexpensive non-primary storage in
our SANs because a shelf of SATA is far cheaper then a shelf of FC.
However, every SAN manufacturer we spoke with directly (about 5 or 6) all
said that their global failure rates for SATA are much higher then SCSI.

My opinion is there is not a problem running SATA drives. To be honest,
I manage a data facility and we have over 450 SCSI drives in the servers
hosted at the facility and SCSI drives fail too. I replace 1 to 2 SCSI
drives per calendar quarter. I run 42 SATA 1 drives in an Equallogic SAN.
This SAN has been online for 14 months and I have not lost a single drive
(these drives run 24x7x365) as the array is hosting several large production
SQL server databases and a large file repository that receives over 3500 new
files per day. That array never sleeps. So, as far a Citrix is concerned,
I wouldn't be concerned about running any of the components from SATA disk
drives. Just make sure you use sound RAID design (as you would with SCSI
drives too) for fault tolerance and you should have no problems. keep a
spare drive on the shelf or online as a hot-spare if your RAID hardware
supports hot spares.
Regards,
Rob

My apologies if this is a repeat:
A client just asked me if there is any reason they cannot run Citrix AS4
on a server using SATA drives.
I have no idea - never tried, but cannot find anything regarding this
issue. Anyone have any experience with this?
Thanks-
Chris
