Raid 0 switch to Raid 1

[jimmyj0668]

The comments I've read concerning the loss of data if your raid 1 losses a drive is making me nervous. Can I switch my setup to raid 1 with little or no problems? I've got two Hitachi 80 gig SATA's running raid 0 on an intel D865PERL mobo with XP Pro SP 2.

Thanks

No, they're completely different:

RAID 0 = striping = speed = each file split up between 2 drives = double the storage of 1 drive

RAID 1 = mirroring = backup = each file witten twice = only the storage space of 1 drive because everything is written twice.

If you have 2 x 120 GB drives, RAID0 gives you 240 GB of storage with a high rate of failure. RAID 1 gives you 120 GB of storage with a very low rate of failure.

You can switch to RAID1 but you'll lose all existing files and half of your storage space.

I was prepared for the loss of 1/2 my drive space but I hoped to avoid a start from scratch rebuild of my OS and files. Oh well, when the very first sign of something amiss in either drive occurs - I'll take that major plunge. Thanks for your input.
