Dual 2.5-inch SATA RAID enclosure

The Vantec NST-272S3-BK holds two 2.5-inch SATA SSDs or hard drives in a single aluminium-and-plastic housing. It connects to a host computer through a USB 3.0 Micro-B port and includes a 5 V, 2 A AC adapter for extra power. The unit supports Windows, macOS and Linux without additional drivers.

RAID 0, RAID 1 and JBOD modes

A hardware controller lets you configure the two bays as a striped RAID 0 array, a mirrored RAID 1 array with automatic rebuild, or as independent JBOD volumes. SATA III drives run at up to 6 Gbps internally while the USB 3.0 link reaches 5 Gbps with UASP support. Each bay accepts drives larger than 2 TB.

Fits into a USB 3.0 workflow

The enclosure draws power from the wall adapter, freeing the host USB port from high-current demands. Front vents passively cool both drives without a fan. A vertical stand is included for desk placement, and LED indicators show power status, drive activity and the active RAID mode at a glance.

Questions about this item

What real-world throughput can I expect from the USB 3.0 Micro-B link on this enclosure?

The USB 3.0 Micro-B connection runs at Super Speed up to 5 Gbps, and with UASP enabled, large sequential transfers reach the practical ceiling of that bus.

How does the SATA III 6 Gbps internal interface interact with the USB 3.0 5 Gbps external link?

Each drive connects over SATA III at up to 6 Gbps, but the single USB 3.0 channel caps combined throughput at 5 Gbps, so simultaneous RAID 0 traffic shares that bandwidth.

What physical clearance and mounting hardware do I need to install two 2.5" drives in this unit?

The aluminium and plastic chassis measures 5.12" x 3.27" x 0.98" and includes a screw set plus a stand, so two standard 2.5" drives fit side by side without extra brackets.
