Hi esuorez,
Welcome to SysChat.
I have been using Seagate Hard drives since very long, they are very reliable. I don't think a Company like Seagate will try to unload troubled merchandise.
As Firefox said its just their marketing tactic to clear off their inventory of smaller HDDs.
Firefox here is the Link for Seagate 250GB HD for $69.99
