We (and by we I mean Jeff) are looking into the possibility of using Consumer MLC SSD disks in our backup data center.

We want to try to keep costs down and usable space up - so the Intel X25-E's are pretty much out at about 700$ each and 64GB of capacity.

What we are thinking of doing is to buy some of the lower end SSD's that offer more capacity at a lower price point. My boss doesn't think spending about 5k for disks in servers running out of the backup data center is worth the investment.

Just how dangerous of an approach is this and what can be done to mitigate these dangers?
