Drive enclosure for 3.5" and 2.5" SATA drives

The Vantec NexStar JX NST-358SU3-BK accepts one 3.5" or 2.5" SATA III hard drive or SSD up to 20TB. It connects to a host via USB 3.2 Gen1x1 Type-B or eSATA. The aluminium and plastic housing provides passive cooling for desktop use.

Included cables and stand add connection choices

The package supplies a USB cable and an eSATA cable so you can switch interfaces without buying extras. An AC adapter powers the installed drive. A screw set secures the drive inside the enclosure and a stand lets the unit sit vertically on a desk.

Check your host ports

Your computer needs a free USB Type-B port or an eSATA port to use either interface. The enclosure fits standard-height 3.5" drives and 2.5" drives; verify your drive thickness matches the bay. No software drivers are required for Windows 10 or 11 UASP support.

Questions about this item

Will the USB 3.0 Type-B port or the eSATA connector wear out from daily drive swaps?

Both ports are rated for thousands of insertion cycles; normal daily swaps will not wear them out within the enclosure's service life.

What limits transfer speed first during a long, continuous copy — the SATA III drive link or the USB 3.2 Gen1x1 connection?

The USB 3.2 Gen1x1 link caps at 5 Gbps, so it becomes the bottleneck before the SATA III 6 Gbps interface does.

How hot does the aluminium casing get when the enclosure runs all day with a 20 TB drive?

The aluminium body and vented design dissipate heat passively; the casing stays warm but within safe operating temperatures for continuous use.
