Re: ????SATA or SCSI????

Les,

The reason I asked it that way is that people tend to discount errors in a
product or technology that they like, and they tend to focus on the errors
in a product that they do not like, or with which they are unfamiliar.

A classic example is Japanese vs. domestic cars. I had friends with Fords
and friends with Hondas who had problems with their radiators. Specifically,
after 110,000 miles, the radiator on my Ford Bronco II started to leak. My
wife's friend had a Honda Civic with 45,000 miles with the same problem. Her
friend said my Ford was a piece of junk because of the leak, but when her
Honda started leaking a week after my truck did, she said it "was just a
fluke."

Ford even did testing with Japanese car owners, and they said they had no
problems with their cars. Then Ford asked specific questions, such as
questions targeted at brakes, A/C, and electrical, and they found that the
people had the same problems as Ford and other domestic makes, but their
**perception** was that is was no big deal.

Equal problems, but since they **perceived** their Japanese cars with favor,
they felt the problems were minor, when in fact they were the same as
domestic makers' cars.

So, the question was absolutely fair. You never considered SATA, which
indicated you do not like it (yet?), and that **could** bias your opinion of
the drive failure as being insignificant in a technology that you like, but
it may have been perceived as a major failure if it had been SATA that you
do not like. That was the point of the question.

That's not a fair question ;-). I suppose it could be more statisically
significant (but outside my experience) if only because I think we hear of
more SATA failures than SCSI failures. I haven't yet deployed a server
with SATA drives and I'd rather not take a chance. SAS is new technology,
I haven't heard a lot of complaints about reliability, but then again I
have no idea what percentage of servers are being deployed with SAS
either.

Manufacturing defects do tend to show up fairly quickly, sometimes stuff
is even just DOA. I still subscribe to the burn-in theory, and like to run
a new server for a week or so before putting it into production, if
possible.

Les,

If the drives had been SATA and one had failed in a week, would you still
be of the opinion that it is not significant?

I just deployed a server with SAS drives. I'm hoping the technology is
reliable - it's certainly fast :-). The choice was between SCSI or SAS,
SATA wasn't considered. The SAS drives/raid controllers offer a degree of
configuration flexibility not previously available - and as SAS is touted
as the technology that will replace SCIS, the choice was made.

I did have 1 of 8 drives fail within a week, but obviously that can't be
considered significant at this early stage.

SCSI

IDE/SATA is fine for TOYS!!

The drives are NOT designed for 24/7 x 365 use and they are slow
(7200RPM)

Western Digital produce RAPTOR drives - these are FASTER 10K RPM
(speed) and designed for 24/7 x 365

I always recommend SCSI - having said that my Server uses IDE - but its
a TOY!

If budget is low just use 2 drive in Mirror (RAID-1) setup

and finally - TAPE backup don't use USB HDD
for what they cost I replace tapes every year - the old ones get used
for MONTH END backup

Hello,

I have just had another SATA HDD crash on me in my SBS- 2003 STD
server and
I was wondering!

Have any other people had problems with SATA when used to hold data in
their
SBS server.

I have been told by a furm that we sometime use when I get a bit tight
on
time that SATA is NO good to be used on Data servers and that we NEED
SCSI
Raid 5!

We have about 10GB MAX on the disks and only about 12 people
accessing, and
maybe only 5 at the same time!

What do you all think??????
