SKU CH-M4EF-4BE42

  • TypeSee Description
  • Hot-swap 2.5" SAS/SATA drives without tools

  • Full metal chassis with ABS plastic protects the drive
  • Supports drive heights from 5 mm to 15 mm

Single-Bay Hot-Swap Enclosure

The ICY DOCK FlexiDOCK MB521SP-B is a drive-bay adapter that lets you install one 2.5" SAS or SATA drive into any external 3.5" bay. It provides SATA hot-swap capability so drives can be exchanged without powering down the system. A full metal chassis combined with industrial ABS plastic protects the installed drive.

For System Builders and Service Technicians

This unit suits builders who need front-access removable storage in a standard 3.5" opening and technicians who swap drives frequently for maintenance or data transfer. It does not suit scenarios needing more than one drive per bay, drives using interfaces other than SAS or SATA, or internal-only mounting without a front-access opening.

2.5" Drive Height Compatibility

The enclosure accepts drives ranging from 5mm to 15mm in height, covering most 2.5" SAS and SATA HDDs and SSDs on the market. Verify your drive thickness before purchase; drives outside this range will not fit correctly.
