I got saegate that are well over 5 years old, running perfectly still.
Only one with bad sectors is an old 10GB that got dropped out of my pocket on my bike @ 60 odd MPH, but its still being used.
My latest Seagate is a 250GB SATA and thats been a little problematic in that it seems to be perfect until I copy a load of files from / to it and then the PC would switch off??? - Does this on all my NF3 and NF4 boards, and originally I htought it could be the BIOS because seagate have been so perfect for me, the last thing I would have thought, is the Drive!
WD are nothing but junk for me, and I would rather not bother and hold out till I get a seagate
Maxtor are a funny breed.
Their older 40GB Drives I have had one for somethign like 4 years now, and I used it for Imesh, Ares, and now Bittorrent, its my Download drive, and its been downloading and uploading half a dozen files non-stop in all this time, like I say roughly about 4 years non-stop and 24/7 too!
I would never bother with any other drive as they are so reliable.
A year or so after I realised how good those drives were, I bought a number of them to use in the kids PCs and they are still 100% spot on 3 years later.
However, the number of bigger drives I have had that have died or are dying, is ridiculous! - I am using a 120GB as a temporary drive for a bit and its been ok for a few months now, but as soon as I get off my bum, its being replaced, probably with a Hitachi or Samsung.
So, if you only need a 40GB, then the Maxtors have proven themselves to me, but any bigger and its seagate.
Only recently I have had an 80GB Hitachi SATA and thats a bit creaky I have to say, but so far seems to be ok. Its nice & fast too.
I got a mate who swears by Samsung, but I myself have had no experience with them, but as you see from previous posts, others like them, so its very likely thats my next option too!
WD however, are fowl ( Even though I have a couple of Raptors ) that are so far great, other models in their range I find unreliable to the point of being offensive to call them good.
