My board doesn't have an eSATA port. Neither does the new dock but at

Exploring an eSATA controller is an adventure for another day . . .

You're suggesting the disks get tested in the case itself, right? Like

I'll keep an eye on that though I won't be accessing this disk often
once it gets trimmed down and some additional files written to it. You
probably noticed from the log that it doesn't even have 100 hours or run
time on it.
