Phillip Corcoran :
I never buy Seagate external hard drives anymore as I've had no less than three fail in less than 12 months.
I replaced them with WD ones and they are all working fine after three years.
Exactly the same here. Though they were three internal Seagate HDDs and they failed in 3 months.
Phillip Corcoran :
Buffalo I've never used so can't comment on those, except to say that the actual hard drive isn't made by Buffalo since they don't make hard drives.
That. Though most external HDDs are actually Seagates. Or at least 90% of the ones i checked out 2 months ago were.
So, my advice would be WD, too.
However, I can assure there are people out there with bad experience with WD drives, too.
