Yeah, that's a good point...
I don't know about Segate, but I was just looking at the warranty on WD drives, it looks like the blacks are still 5 years, but that's $70 more than this drive, so probably not worth it for just the warranty.

Another option would be a squaretrade warranty which is up to 4 years for $20.
