The EF51R is the smallest drive of DEC’s first generation of solid state disks, 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
Apart from the DSSI interface, the EF51R disk drive is identical to the EZ51R Solid State Disk Drive.
