Thanks.

Was thinking of raiding 2 120 drives in Raid 0 but if one drive gos
both go :(

Any other options.

Thanks.

Your only other two-drive options are mirroring (RAID 1)
and a new thingie not widely supported by RAID card/chip
manufacturers called RAID 1.5

Can't remember if it was Promise or HighPoint that had
a press release about 1.5 a few months ago.

If you get data corruption with raid 1 you lose both drives,if you get data
corruption with a single drive you lose it .

Data corruption has nothing to do with RAID, any version.

If you have Drive 0 have a physical problem that causes corruption of
the data on the drive, the drive will mark the sector as bad and replace
it with another sector. Drive 1 will still have good data since Drive 0
can not write to Drive 1 - only the controller can write to the drives.

As for loosing either drive, or loosing a single drive, you are better
off with a dual drive set using RAID-1 (Mirroring).

While you can lose hardware it is highly unlikely that you would loose
two drives at the same time.

RAID-0 is typically only used for Video/Audio or when the highest
performance levels are needed for file access. Most home users will not
benefit from RAID-0, and the added chance of loosing everything by
having two drives in a striped set is not worth the risk.
 
dont' you hate when you get typing fast, without looking, and put to
many characters in a word - like loose or lose....
 
Yip, its even worse when your keyboard is tuffed and leaves stuff out or
when you find that you have voice recognition software running in the
background completely unaware and you say something like b***d* idiot just
before hitting send :)

Hi,

I'll clairfy what the others have said using a lot more words.

RAID 0 - Striping - High performance, double the risk of losing all data if
1 disc fails.
RAID 1 - Mirror - normal performance, the risk of lost data from a drive
failure is greatly reduced.
There are several other types of RAID...

If you want reliability, use RAID 1.
If you want performance and don't care about reliability (EG video editing)
use RAID 0.
It is not a good idea to put Windows on a RAID 0 unless a) you can afford to
spend several hours recovering your system after a disc crash, b) disc
crashes don't worry you c) you have excellent backups.

IDE discs on not all that reliable, and multiple disc failures in RAID
systems do occur - I had one recently on a customer site. You *must* have a
good backup system.

You indicate above you have an A7V266-e. Well I don't have one nor the
manual (A7V266 + others) . If the machine does not have RAID already then
get a RAID PCI card. They are dirt cheap now. Review comments in this group
about the different makes - I don't think you will find any negative
comments about any of them. IE many people have trouble understanding /
setting them up, but the cards themselves seem very reliable these days. If
you want a SATA PCI RAID card, get one that as a minimum has a Silicon Image
chip on - in US$ these should start around $25 now - the cheap ones may not
be too well made, but with the SIL chip it should work 100%.

If you are going to get a PCI card, get one that will allow you to move the
RAID array without issue to different machines without data loss. Check the
card suports the type of RAID you choose: some cheap ones only support RAID
0.
