I've got a brick of a 2TB Seagate thing on the shelf beside me, formerly of backups duties, awaiting secure destruction of the hard drive platters next time I have a WEEE sort-out.
It turns out that they don't like being dropped. But that's hardly surprising for spinning-rust disks, and I wouldn't hold it against them as a manufacturer. I've got a sever full of Seagate drives behind me, and their reliability has always been ...adequate[1].
(It also turns out that if you remove the drive from the enclosure, it doesn't function as a normal desktop SATA drive. Different firmware that only works with the USB-ification board, or something.)
[1] Disks fail, that's just what disks do, which is why you have more than one of them. In recent memory, I've found that Seagate disks mostly out-live their warranty period.
