04Sales
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:
- Much faster
- Higher capacity
- 2-year warranty
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.
