The drive controller knows nothing about "filesystems". It just passes bytes to and from a device. The OpenBSD installer will just use the disk portion that you allocate to it. It will not waste time inspectioing what was on the disk before. Will there be pieces of the disk that still contain untouched data blocks of files that existed on some previous filesystem? Yes, they might. > Is this a concern? No. > If so, how does one "reset" a used SSD for > optimal operation with a fresh install? Just treat it as any other disk - which it is.

It is, if you say so in the installer. Making sure there are no datablocks left over is another thing. The first question would be why would you concern yoursewlf with this.
