What flavor of SCSI did the Zip 100 internal use?

[Steve]

Anyone know? 5MB/s, 10, 20?


For that matter, anyone know how fast it actually sent and received data?

The zip 100 internal didn't have a SCSI interface.

It was ATAPI. They were pretty slow.

They came in both SCSI and ATAPI flavors - but the specific SCSI version is not cited:

ZIP

According to the specs, it was SCSI II, sustained throughput of 1.4 MB/sec.

Thanks corkyg, I asked the same question at Iomega's forum and was told it used the 5MB/s type of SCSI. They also mentioned the .78-1.4MB/s throughput.

That's correct, Steve. The SCSI II specs do allow for the higher throughput, but in the case of the Zip drive, that is constrained by the disk I/O parameters themselves. IOW, they operate in a 5 MB/sec speed limit area, but don't have the HP to go that fast.

That's one reason I never went for a Zip drive in spite of their immense popularity. I opted for Syquest SCSI E-Z Drives instead - much faster even at SCSI I. I still have them, and they still work with a SCSI-Firewire converter. (Firewire is basically extracted from SCSI III.) Syequest Flyers and SyJets were SCSI III.

I then went to LS-120 drives and disks for higher volume archiving. Still have them and they still work.

Cool, I still have an LS-120 disk in a bx somewhere from an old summer job. Never had a drive of my own. Did they ever make internal versions of the LS-240?

Anyway, I built my mother a PC to replace her old, old Mac. They only removable storage she has for the Mac is an external USB Zip 100. I happen to have an internal SCSI Zip 100 I could pop into the PC so she can sneakernet away. I'm glad I have a couple of SCSI cards that will handle it too.

Yes! I have it installed in this machine as Drive B. It is backward compatible with LS-120 disks. It is a good performer, but got killed quickly by flash memory drives.

I have all of the SyQuest SCSI externals - EZ-135; Flyer, and SyJet. The EZ was SCSI I, and the latter two are SCSI III.

Yup, use USB Flash drives for your sneakernet now. Easier, faster, cheaper and more reliable.
