Before you put important data on every new drive you buy (even if it's going to be a part of a redundant RAID array), you must test thoroughly every single sector for read/write, using manufacturer's tools. I use WD Diag Tools that work for all hard drive brands I have by running an extended test. It will take 3-4 hours for 1TB drive, but it's worth it.

For more important data, put the drive under continuous 24 hour read/write workload, and run the full media test again.
