Cast aluminum-constructed removable drive enclosure designed for mounting any 3.5" form factor, low-profile (1") SCSI, Serial ATA (SATA) or Parallel ATA (PATA) drive into a 5.25" half-height peripheral bay. All RhinoJR removable models feature cooling fan(s) and a front-accessible key lock/power switch which secures the carrier within the receiving frame. For continual removal applications and/or rugged environments, CRU DataPort and Data Express enclosures are suggested. For applications requiring frequent drive swapping or replacement, CRU-DataPort recommends the rugged DataPort or Data Express removable enclosures for high insertion environments.
