SilverStone TS431U
3.5-Inch External Hard Drive Enclosure
Street Price

Though mostly known for the cases and power supplies, SilverStone sells a variety of storage devices and accessories. The TS431U external enclosure sets itself apart in that it's built and styled in SilverStone fashion, lending a bit of panache to an otherwise utilitarian product type. There are plenty of multi-bay enclosures on the market but most of them are designed for function rather than form, sort of like how PC cases used to look in the boring beige box era.

The TS431U.

The TS431U is built like a tank but is graced with a classy SilverStone brush aluminum door. It's a plug and play device supporting up to four 3.5-inch drives and is cooled by two 60 mm fans at the back. Like most enclosures of this type, it can connect either through USB 3.0 or eSATA. The TS431U is one of three SKUs that use the same chassis design. The TS431S and TS432U are identical except that the former uses a miniSAS interface, and the latter has a front control panel and RAID functionality.

The TS431U on the otherhand, is just a basic enclosure that expands the storage capacity of whatever PC it's connected to, effectively adding four hard drive bays, only externally rather than internally. I personally use such a device to perform regular local backups of my desktop as an alternative to having a dedicated backup NAS running on the network. The TS431U similarly has no network capability, so it can't share data with other machines, nor are there any redundancy features (RAID).

TS431U box and contents.


The TS431U ships with ~100 cm long USB 3.0 and eSATA cables and a slightly longer power cord. No external power brick is provided as the entire power supply unit is incorporated into the internal design. A software disc is included but there's nothing on it for the TS431U except for the manual.
