Some questions about Raid 0. its for a new PC.
From what i read raid 0 is the fastest version. But not the safest.
Not realy concerned about safe just want fast :)
Ill have abackup program saving important stuff to another drive.
Anyways heres the questions.
Does raid 0 put any extra stress on the drives. Iam going to use two
160 gig or 200 SATA 2 drives. 200 gigs if i can get them. But 160 gigs
X2 will be fine.
If they work harder would extra cooling help them not to fail. My pc
is pretty good with the cooling and i have no lost a drive since my 2
gig Maxtor ages ago.
Also with raid 0 from what i read i will have 2 160 drives storage.
320 gigs of storage i can use. And unlike if i raided them to raid 1 i
would only have 160 gigs while the other drive would be for backup
This would be the first time i have raided a drive. Was going to to it
with my old board but never got arround to it. But now iam builidg my
uber pc i realy have to :)
Amd 3800 X2, 7800 GT, 2gigs PC3200 LL ram, 2 SATA 2 in Raid 0. And
everything overcloked as well.
Thanks for any help.
Re: Some questions about Raid 0. its for a new PC.
No. Each drive works just as hard (but no more so) as it would in a single
disk configuration. The only difference is that both drives are working
together. It's actually the other types of RAID array (striping/mirroring
etc.) that cause the drives to do "extra" work.
They don't work harder so this point is largely moot. However, whether you
use a single drive configuration or a RAID array, it's always worth making
sure that the disks are adequately cooled. Most modern ones will report
their temperatures to utilities like MBM, SpeedFan and the drive's own
utilities, so it's relatively easy to be sure about the cooling aspects.
Hard disks are generally pretty reliable. Apart from a few spurious
exceptions, there's no reason to expect you should run into problems.
RAID 1 isn't backup in the traditional sense. It only provides you with
backup in a given set of scenarios (e.g. one of the drives suffers a
physical failure). If you, for instance, deleted a file off a RAID array,
and then wanted to recover it, you'd still be screwed as the file would be
deleted off both drives at once. As such you might still require a
"conventional" backup solution.
Frankly, you don't really *need* to do it. Modern SATA hard disks are fast
enough for pretty much any application you are likely to want to do. The
historical uses for which RAID 0 used to be necessary - for instance
real-time DV video capture via Firewire, can now be done quite comfortably
on a single typical modern 7200rpm drive.
Indeed, given a pair of fast modern drives, it may well be that you would
obtain better performance in some scenarios by configuring the disks in
conventional non-RAID mode, depending on what you do with your system. Think
carefully before you proceed!
