RAID setup question
Posted by: pqrst
Date: April 25, 2009 07:33PM
Hi there
I wanted to ask a question about preparing for a future RAID setup. I want to buy a largish (1TB+) sata drive and use it for a backup now using a usb->sata drive adapter. However, I want to use the same drive in a hardware RAID 1 enclosure in the future (buying a matching drive for the second drive.) Will I be able to just put the drive and a new drive into the enclosure and have it work? Or will I have to transfer/backup my drive, setup the RAID and then copy it back? Thanks in advance.

USB->SATA drive adapters are not reliable and are not made for long-term use. You should buy a drive enclosure for it.

When/if you try to use that drive in a RAID you'll lose all the data on it. You'll need a backup of your backup drive.

RAID 1 will protect you against a hardware failure but nothing else. you're better protected with a time machine backup

or just one drive copying to another via software like CCC or superduper

i dont see the need for a RAID with what you want...

I should have been a bit more specific.... I'm going to use the drive (and the RAID) for media and editing files. Not a backup... sorry about the use of that word. The reliability of the RAID is needed because we don't want any downtime when/if one of the drives goes down. The use of the usb adapter is just an interim measure to get the data on the drive (and until we get the RAID bridge board we ordered.) Thanks for the help.
