The EF51R is the smallest drive of Digital Equipment Corporation’s first generation of [[Solid State Disk Drive]]s packaged in a full-height, 5 1⁄4-inch form factor. The EF51R ISE provides non-volatility of data by a data retention system including:
* Power sensing logic
* An internal winchester magnetic disk drive
* A battery to power the EF51R while dumping data to the winchester disk
