Best Sata Drive for shelving.

I work for a small production company with a few clients (go through maybe 500GB of data a month)
Since currently we can't afford more expensive longer term archival solutions and we rarely need to access old projects we will simply be taking our final project folders and transferring them to duplicate 3.5" sata drives for shelving.


With cost in consideration does anyone of any recommendation or know what things I should be looking for in the drives we choose to use. We use enterprise grade drives in our RAID, but for this purpose since they will not be spinning or used in a raid will they be any safer?

We like to find the most cost effective 500GB drives with lease possibility for drive failure. The speed of the drives is not much of a consideration.


thanks!
