Hard drives

[Lumpjaw]

Hey all,

I am needing to get a Server together and need to get some feedback on
harddrive types. I am going to need to build a very redundant system, my
initial thoughts are 3 drives in a raid array and then 3 more drives that
mirror the first 3 (if that is possible). Get someone give me the ins and
outs of the different type i.e. SCSI, SAS, SATA, IDE, etc that would work
better than the others and provide the best dependability? Thanks -lumpjaw

RAID6 with a minimum of three SATA harddrives is one option. Two
harddrives may fail concurrently and you'll still have your data.

Serial Attached SCSI is a very good solution for enterprise, but it ain't
cheap.

How many users will you scale to ? What's you budget ?

I have to agree with the last reply from "JD Cantifio" the "RAID6 with a
minimum of three SATA harddrives is one option"
Old habit is Loving RAID configuration on massive servers. It "Might" one
day prove to be a bad habit, but it is a habit
drawn from the days of SCSI drives..LOL...

It;s hard to say, but under :"normal"-conditions, I would commonly go with
atleast SCSI or SATA (habit created from spending WAY TOO many very
latenight hours trying to recover from damaged IDE's, expected to be
recovered and back by the next biz. day...hehe....
I, personally, am pretty much a fan of RAID system because of the redundancy
of stored data making them much easier to recover, especially if they were
anything like little PCMCIA and IDE drives where the owner(s) wanted every
ounce of data they could get for Evidence in some legal case (usuallly
lawyers,DA's and large RailRoad companies), from IDE remains brought-in in
baskets or trashcans for evidence recovery. You'd declare me whacko but I'm
also an insane fan of Linux Op. Systems, ecspecially for banks and larger
loan firms and financial accounting-concentrated firms.....Caldera, Debian,
even Redhat, and "MAYBE" even Suse, etc....hehe).
