Dual 2.5-inch SATA/SAS dock

The ICY DOCK MB522SP-B converts a single external 3.5-inch drive bay into two hot-swappable slots for 2.5-inch SATA or SAS hard drives and SSDs. It accepts bare drives from 5 mm to 9.5 mm thick without trays or caddies. A full metal chassis with ABS plastic panels provides structural rigidity and drive protection.

Builders using legacy 3.5-inch or floppy bays

This unit suits system integrators and enthusiasts who want to repurpose an unused 3.5-inch front bay for modern 2.5-inch storage. It is not for cases that only offer 5.25-inch bays, nor for users who need more than two drive positions or a tray-based mounting system.

Tray-less hot-swap with direct SATA connection

Drives insert directly into the backplane and eject via individual safety buttons with integrated activity LEDs. The interface supports SATA I, II and III as well as SAS at up to 6 Gb/s, limited only by the installed drive’s own speed.
