What this drive does

The Iomega Z250ATAPI is a 3.5-inch internal backup drive that reads and writes 250 MB and 100 MB ZIP disks. It connects through an IDE/ATAPI interface and is supported on both Windows and Mac OS. The unit weighs 13.8 oz and measures 6.5" x 4.0" x 1.0".

Who it suits and who it does not

This drive suits users who need to access existing ZIP 250 or ZIP 100 archives on a legacy desktop with an available IDE header. It is not for builders who need gigabytes of capacity, sub-millisecond access times, or a modern high-speed interface. It also cannot serve as a primary system drive.

The specification that decides fit

The IDE/ATAPI interface is the single factor that determines compatibility; the host system must provide a matching 40-pin connector and BIOS support for ATAPI devices. Sustained transfer reaches 2.4 MB/s with 250 MB media and drops to 1.4 MB/s read and 0.25 MB/s write with 100 MB disks.

Questions about this item

Do I need a spare IDE/ATAPI header on my motherboard to connect the Z250ATAPI?

Yes — the drive uses an IDE/ATAPI interface, so an available IDE channel and a standard 40-pin cable are required.

Will the Z250ATAPI still read my existing 100MB ZIP disks?

Yes — the drive reads and writes both 250MB and 100MB disks; sustained rates are 1.4MB/sec read and 0.25MB/sec write with 100MB media.

How can I confirm the drive is performing at its rated 2.4MB/sec sustained speed with a 250MB disk?

Run a large sequential file copy in Windows or Mac OS and verify the transfer rate approaches 2.4MB/sec; the burst rate can reach 26.7Mbits/sec.
