Yes, it would be more economical to replace laptop drives every
couple of months than an SSD every year.  <frown>  Or, maybe
look at some of the small form factor SCSI drives (*intended*
to run continuously -- unlike laptop drives).

I think I will have to look for a hybrid solution.  Maybe some
slow RAM packaged to *look* like a disk.

The dirty little secret, here, is this is accomplished by selling
a larger drive branded as a smaller one!  :<  "Ain't no free lunch!"
