Thinking I could image a 2GB SCSI disk running on the Mac II was a bit ambitious... after letting it run all night it wasn't even 1% complete #MARCHintosh

@ben - don't use the "compressed" option when making a backup. It's not necessary. Do a read-only or read-write image. It will go significantly faster.

@ben Hmmm... My recollection from the late 90s was that base SCSI was 5 MB/s although most disks couldn't saturate the bus. But 1 MB/s was certainly doable so I'd expect 2 GB to be copyable in under an hour, at least if sequentiality.

@ben Like @theirongiant said, this is all down to using the compression option in Disk Copy. A read-only (uncompressed) image will be orders of magnitude faster to create.
