Scott Mueller's Upgrading and Repairing PCs Forum

Hello Scott,

Following a recent psu failure which took out 2 hard drives, I've decided that my PCs should have only 1 drive each, for the OS. Data will be on external drives using a docking station with it's own power supply.
I'm thinking of buying one of these.

To be honest, I can't see much between them and I'm inclined to go for a dual-drive model in order to be able to copy from one disk to another for easier backups, although this obviously makes two disks vulnerable to the same external psu for the duration of the backup process. The safer alternative would be to copy data to the internal drive, then out to a different external drive, so that there are never more than one internal and one external disk connected simultaneously, each with it's own psu. I'd really appreciate your opinion . Have you known external psus to fail and destroy the disk they're powering?

Thank you.

Mike
