I just received an email from Crucial saying that they are going to have a sale on refurbished M225 SSDs for $1 per megabyte. How do these SSDs compare to the competition? In looking at one review of SSDs, it looks very middling at best. Also should one be leery of buying a "refurbished" SSD? Don't the performance of these degrade over time? Having said that, would using one of these as a boot drive "blow away" my WD black edition? I would be tempted to get a 128 GB for $128 but then again don't want to feel like a few months down the road, gee I wish I would have waited/bought brand X instead.
