Looks like Samsung is clearing out their small capacity 250GB for $45. Useful for a final kick in speed for all those ageing SATA systems, before throwing them in the junk pile.
It only has a 150 TBWritten rating (larger capacities double TBW with doubled size) so be sure you only use it in light usage systems. Does have 5 year/150 TBW warranty though if you do hit problems before then.
