Re: What is RAID0 good for?

My friend has a Win XP  PowerSpec B647 desktop with two 250 GB hard

happens to one drive happens to the other, so when she was infected
with a virus both hard drives were infected, and both were
simultaneously cleaned by the same antivirus scanner.

What good is having those 2 drives perform like that when she is a
non-techie home user who would be better off with the use of 2
independent hard drives? Is there a way to turn off the RAID behavior
so she can get usage more suitable to her needs? Thanks.

RAID 0 is nor really RAID as there is no redundancy. As discovered,
if one drive fails, in effect all data is lost.

The reason for it, in theory it will make the drive run faster. For
the average user, this speed difference may never be seen.

A safer option would be to use JBOD (Just a Bunch Of Disks) and
concatinate the two to make a single 500GB drive.

If a 500GB drive was not required, then 2 x 250GB drives would be a
nice simple solution. This is the option I would choose.

To protect against single disk failure, you require RAID 1. However a
virus problem would still ingect both drives.

To change the setup will require reformating both drives, and so all
current data MUST be backed up first, and then the operating system
etc will need reloading. Probably not worth the effort, just make
sure you have regular backups.
