I don't disagree that there are issues with an SSD's limited write cycles.

But its a moot point.

The SSD is used for caching and if there becomes a problem, you can replace the SSD. (Assuming that these are not chips physically on the controller board but a plug in sub board or something similar.)

The other key point is that this is a lower cost alternative to other solutions. You have to admire that it works and is affordable.

While I am not an adaptec fanboi, I do admire their products and have used them for 15+ years in various machines.
