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.[1][2]
A successor drive, known as the SyQuest EZFlyer, was released in 1996. It was backwards compatible with the EZ 135 disks, and could utilize a higher capacity 230 MB disk.[3]
