I don't want USB powered as the drive is only powered up once or twice a week. If it's USB powered then it's always on and I don't want that.
FWIW I have three 3.5" external drives, all 250GB; 1 Maxtor external bought in May 2005, and 2 Maxtor internal drives which I mounted in caddies, they were both bought in April 2008. I also have a Samsung 2.5" 750GB, some 18 months old, which is USB powered and always on being the backup drive used by Genie Timeline.
I'm looking to replace one or more of the 3.5" due to running out of capacity. Though clearly with 3.5" drives that old I realise that they may well be coming close to end of life.
We have more and more laws, and less and less enforcement
