Long term performance is the big worry with SSDs.

Early drives delivered scorching performance out of the box, but quickly went down the toilet with intensive usage.

To simulate a used drive, we install Windows 7 and then stuff each SSD full of data. This used to be enough to make SSDs suffer slow downs. More recent SSDs are much more resilient.
