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.

Questions about this item

Will this tray-less U.2 NVMe enclosure fit the same 3.5" bay I currently use for a mechanical drive?

Yes, it mounts in any standard 3.5" front bay so you can reuse the opening without case modifications.

How can I verify the Slimline SAS 8654 link is running at the full 64Gbps after installation?

Check the negotiated link speed in your OS device manager or BIOS; it should report PCIe 4.0 x4 for the 64Gbps throughput.

Does the MB021VP-B include the SlimSAS cable or do I need to buy it separately?

The enclosure ships with the drive tray only; a Slimline SAS SFF-8654 cable to your motherboard or HBA must be purchased separately.
