Manufacturer description

The ORICO 3139U3 is a 3.5-inch external hard drive enclosure that turns a bare SATA 3.0 drive into a desktop USB storage box, and the transparent shell is the reason most buyers pick it over an opaque plastic case. You can see the drive label through the housing, so identifying which disk is loaded takes a glance instead of a teardown. The USB 3.0 interface moves data at up to 5 Gbps, roughly 10x the ceiling of USB 2.0, and UASP support keeps queued transfers efficient when you are copying large media libraries or running backups.

Frequently Asked Questions

What size and type of drive fits this ORICO enclosure?

It takes a single 3.5-inch SATA 3.0 hard drive or SSD, with support for capacities up to 16 TB per ORICO's specifications.

Do I need a screwdriver or any tools to install the drive?

No. The 3139U3 uses tool-free assembly, so the drive slides into the housing without screws or a screwdriver.

Does it need external power, or does USB supply enough?

It ships with an external 12 V 2 A power adapter. A 3.5-inch drive draws more than a USB port can supply, so the brick must be plugged in.

How fast is it, and does UASP actually help?

The USB 3.0 port is rated up to 5 Gbps, roughly 10x USB 2.0. UASP handles command queuing, which mainly improves throughput on large or multi-file transfers.
