I'm looking to upgrade/replace the Seagate ST32000641AS with an SSHD. There is nothing wrong with the Seagate, but since it is over 5 years old, I'd rather replace it before it starts to fail rather than after. I'm looking on amazon, and I found two 2TB sshds by Seagate. One is a Seagate Barracuda, the other is a Seagate FireCuda. There is a $15 difference between the two drives. Anyone know what the difference is between the two that makes the firecuda worth the extra money?
