Hardly surprising

They've probably spent most of it on handling drives returned as defective.

The 1TB+ Seagate drives are suffering from abysmal quality control issues - it wouldn't be a stretch to say that as many as 50% or more of these higher capacity drives will suffer an excessively large number of reallocated sector errors within the first few days of operation, enough to require a replacement (which will of course be with a refurbished drive, one that is just as likely to have the same reallocated sector problem).

SMART monitoring software will send you nuts by repeatedly warning you about the ever increasing counts.

Google for "seagate reallocated sector count" to see for yourself - anyone buying a Seagate drive these days should have their head examined, they're just shit.
