The EZ 135 Drive is a 3.5" removable platter hard disk drive. It was introduced by SyQuest Technology in 1995. It had a maximum capacity of 135 MB per disk.
The EZ 135 drive was available with several interfaces. The external drive was available with parallel or SCSI interfaces; the internal drive was available with IDE or SCSI interfaces.
The EZ 135 Drive was designed to be a competitor to the Iomega Zip drive and LS-120 SuperFloppy. The original box listed several advantages:
Additionally the removable hard disk cartridges included a 5-year warranty.
Unfortunately, the EZ 135 drive was not backwards compatible with other SyQuest drives, and the original capacity was never increased beyond 135 MB. The Zip drive became popular and SyQuest's sales declined.
