So... i was looking for a SSHD from Seagate, but here in my town there's only the oldest version, the ST2000DX001. I know that there's a new one, the ST2000DX002 (aka Firecuda) and i was looking toward the difference between these two SSHDs and haven't found any major update (or did i miss something?). Can anyone tell why shouldn't i buy the oldest one and wait for the Firecuda to arrive?
