Summary: Seriously guys.. people here giving 1 egg and complaining because their drive lasted FOUR+ YEARS? That's all you should expect, how silly.
Pros: 43,000 power-on hours.. basically means this drive has been running almost non-stop since I got it. Impressive reliability, however my speeds are just now starting to drop off so I'm looking to finally retire it. This drive was from the golden age of seagate and hard drive reliability.
Summary: I bought 3 drives in 2010. 2 of the 3 drives failed within the first year. The realiability of Seagate's storage products has plummeted over the last 5 years. Read any of their storage products reviews. They are not your grandfather's drive anymore.
Summary: Used as a back-up, to a back-up, disk only. Lasted just over two years before failing without warning. Seagate's site hung on my address and would not authorize return. Had to use different address to get things to go through just so they'll send me a re-certified drive.
Summary: all i will say is it works. the original that came with my pc lasted for 4 years. these hard drives are known for premature failure, but i needed to replace with the original model in order to do a system recovery.
