5 out of 5 eggsRock solid at 4 years

Pros: 7200 RPM, Good storage capactiy, solid reliability

Cons: 640 GB has gotten to be a bit small for a lot of people, but its still a great drive.

Other Thoughts: I've been shopping around for some new hard drives to throw into my PC for a while. I'd love a SSD for the OS and a 2 TB for bulk storage, but I thought I'd look up my current hard drive while I was at it. And since I know the true value of a hard drive is measured in its lifespan and reliability, I thought I'd leave a review, in case someone comes across one of these at a great price.

5 out of 5 eggsThe Methuselah of HDDs.

Pros: I have owned this hard drive for SIX YEARS with zero issues. Just in case it croaks I'm currently using it as a backup drive, but it's no slower than when it was new.

Cons: Due to all the new builds I've cycled this warrior through, the SATA port is a bit wobbly - and roughly 1/10 boots the system won't recognize the drive. It's been doing this for about three years, but there are zero drive errors so it's merely a mild inconvenience. A single restart fixes this EVERY time.

Other Thoughts: Probably a better deal to get something higher-end these days, but this is the most reliable single piece of hardware I've ever owned, period.

5 out of 5 eggsOne finally died after 5 years

Pros: I had two of these running in a NAS and this last summer, after 5 years, one of them finally bit the dust.

Cons: Drives don't live forever - that's why I used RAID1

5 out of 5 eggsGood drive

Pros: Ran for the last 5+ years no problem.
Takes all the abuse of me throwing data at it like a champ.

Cons: -not as fast as a ssd but what do you expect?
-Nowadays you can get bigger drives then this with larger caches and size in general but I also bought it in 08

5 out of 5 eggsTwo Running in Raid

Pros: Bought two and a raid controller in 2009, both still working without a hiccup. Bit old tech now but still get the job done.

Cons: Won't make me coffee very often

Other Thoughts: Computer hasn't been off more than 3 hours since it was turned on (has been a quasi server most of its life)

4 out of 5 eggsBad sectors appeared after 4-5 years

Pros: I bought 3 of them in 2008/9. Two which were bought later (2009) are still running without any bad sector.

Cons: First HD, where OS resided, started to show some signs of aging. Few bad sectors appeared after 4 years or sow.

5 out of 5 eggs5 years of heavy use

Pros: I am very surprised that this thing lasted as long as it did. 5 years of music listening/editing, VIDEO EDITING, 3d animation and gaming, and sectors are JUST NOW going bad. All that, plus the computer was pretty much on 24/7 for the past 5 years, acting as a media server for music and video. I was even able to back the whole thing up after running chkdsk. A++++ product

Cons: Nope, can't complain
