Backup solution for Intel Mac

I have a Intel based iMac.  Snow Leopard  It has a 500 GB internal.

I also have a 500 GB external


I would like to buy a 2 TB mirrored external to store and  backup my image files.

It would need to be configured to RAID1. Is there anyway to incorporate my

existing 500GB external into the mix?

Also I have been reading about problems with Intel based Macs and My Book Studio ll

externals.  Could someone elaborate on that as that seems to be a good system but

for me–maybe not?

Thanks for any and all advise.

Well haven’t read about such problems

but consider this one

the 500 GB external drive will work if you daisy chain to the MB Thunderbolt

Never heard of issues with Intel Macs and My Book Studio II.  The best solution will be a Thunderbolt Duo, can be used with Time Machine or with the backup software of your preference.  Confirm if your iMac has a Thunderbolt port.  Also the Thunderbolt cable is sold separately.
