This is a pretty decent HDD, but is marred by one issue...
Pros-
*Quiet.
*Runs quite cool.
*Good value for money.
Cons-
There is only really one con to this drive, and that is that older versions shipped with a faulty firmware. This meant that if the S.M.A.R.T. "Identify device" command was issued while data was being written to the drive, a loss of data occurred. As Samsung failed to change the version number on the new firmware that they released, it is impossible to tell which version you have. I have e-mailed Samsung, and they assure me that any drives with a build date after 11-2010 will have the new firmware pre-installed, which mine did.
As all 3 drives I ordered were built on 12-2010, I think Amazon may have cleared their old stock, so you will probably be ok with buying one.
Other than this issue, the drive is excellent.
