ICY DOCK MB021VP-B U.2 NVMe PCIe 4.0 drive enclosure 3.5" bay SlimSAS 64Gbps

3.5" bay U.2 NVMe enclosure

The ICY DOCK MB021VP-B is a tray-less enclosure that lets you install a 2.5-inch U.2 NVMe SSD into a standard 3.5-inch drive bay. It connects to the host through a single Slimline SAS SFF-8654 cable running at up to 64 Gbps. The aluminium and ABS body weighs .6 lb and requires no AC adapter. No tools or screws are needed for drive changes.

Suits tool-free U.2 upgrades.

This unit targets builders who want to add one enterprise U.2 NVMe drive to a desktop or workstation without opening the case. It supports a single SSD only, so users planning RAID sets or multiple simultaneous drives should look elsewhere. The enclosure has no fan, making it unsuitable for sustained heavy workloads that demand active cooling. Operating system support is limited to PC platforms.

SlimSAS SFF-8654 64 Gbps host link

The decisive specification is the Slimline SAS 4i (SFF-8654) connector wired to the SFF-9402 Rev 1.1 pin-out, delivering up to 64000 megabytes per second across a PCIe 4.0 x4 pathway. If your host controller or backplane lacks this exact SlimSAS interface the enclosure cannot operate.
