That same argument would apply to flash drives, since flash units larger 
than 32GB (or even 16) are prohibitively expensive, and need to be 
changed as well.

The problem with hard drives is once removed from a system they are 
extremely fragile, as was pointed out earlier.

Tape systems are beyond what most consumers want to spend, especially if 
you include a SCSI controller.

Which leaves no really good answer, the reason for my original post.
