5 out of 5 eggsVERY reliable HDD

Pros: What can I say back then when I purchased this HDD "2008" it was one of the fastest hard drives you could buy under the raptors. I still use it in my main system which is also from 2008.. I just recently purchased 1200$ in parts so I will soon only use this HDD as a backup/storage for pictures and so forth..

However the reliability of this HDD cannot be understated 7 years is a very long time... Runs as fast as it did day 1 and hasn't given a single error

Cons: no cons, except its slightly outdated in todays terms

5 out of 5 eggsReliable.

Pros: Power on hours currently at 59980; almost time for the 60k party. That's nearly 7 years of 24/7 uninterrupted service; three system rebuilds, including a SFF that was shipped around the US multiple times in less than ... ideal conditions. Probably the longest running piece of computer hardware that's currently running in my systems.

Cons: 640GB is getting a little small.

Other Thoughts: Western Digital and HGST are the companies to beat in mechanical storage.

5 out of 5 eggsStill going

Pros: I bought three of these almost eight years ago. Since then all three have about 35,000 power_on_hours. One developed some bad sectors a couple years ago but after a reformat is still usable. I am using that one as a secondary backup. The other two are all good.

Cons: I seem to remember having to flash the firmware in order to get these to run in RAID. Wasn't a problem though.

Other Thoughts: They don't make them like they used too. Since I bought these, over the years I've probably returned a sixth of the hard drives I've bought due to failures **cough** seagate **cough**

Also, I paid about ninety dollars eight years ago for one of these. Today in 2014 it is three dollars less than what I paid.
