Mithun, if you wish, you can share why you are going for an upgrade. People

Personally, I do not consider a backup a backup, unless it is on WORM media.
Unexpected power problems among other things can completely ruin harddisks
in a jiffy. Critical data should be backed up on indestructible(via software
I mean :)) media IMHO.
My 2 cents...
Hope that helps.
