The '''RC25 disk drive''' was a combination [[non-removable-media disk]] and [[removable-pack disk]] (using a sealed [[pack]]) on a singled [[spindle]], from [[Digital Equipment Corporation|DEC]]. Each 8" [[platter]] had a capacity of 25 MB, for a total of 52 MB. It connected to the [[device controller]] via the DEC standard [[LESI]] [[bus]]; a second 'slave' drive can be connected to the first 'master' drive. it uses the [[Mass Storage Control Protocol]], and is member of the [[Digital Storage Architecture]].
