For a minute I thought it was the Next. But that was a bomb that went off 32 years ago.
Most everyone I knew who had one added a SCSI hard drive real quick to their NeXT cube and moved stuff like swap there, and eventually folks figured out how to replace the optical as the boot drive. If you were desperate, you could swap to NFS which while not much faster was usually smoother (and quieter) than swapping to the optical.
