Pros / A rubberized exterior offers military-grade shock resistance and keeps it safe from accidental damage.

Cons / The included data backup software can be a bit complex to master for the casual user.

 Verdict / The Transcend StoreJet 25M3 1TB external hard drive for PC is tough and durable, but its versatile backup software may require a bit of a learning curve for beginners.

Built with a focus on durability, the Transcend StoreJet 25M3 is one of the best external hard drives you can buy. This portable hard drive has a triple-layer chassis built to easily withstand the bumps and drops sustained through heavy everyday use.

The StoreJet 25M3 is equipped with a USB 3.0 port compatible with USB 2.0 technology. This indicates that it can be used with any computer still operating with USB 2.0 technology, although transfer speed rates may be slower. A USB 3.0 cable comes with the portable external hard drive.

The best portable hard drives on our lineup come in a variety of different storage capacities, and the 25M3 is no exception. You can choose between 500GB, 750GB, 1TB and 2TB versions.

The software user interface is intuitive, with useful icons that lay out an orderly list of options for performing simple tasks; however, performing more in-depth functions can be a bit complex. There is no option to password protect the portable hard drive, which could be important to some. Backups can be scheduled in hourly, daily or monthly increments.

The StoreJet 25M3 has a rugged design that excels in durability, featuring heavy-duty drop protection designed to fully protect its inner components. The chassis conforms to U.S. military-grade compliance standards. The built-in shock resistance of the rubber casing ensures that the drive can survive 5-foot drops without risking any internal damage.

A direct result of the external hard drive's drop protection is its weight; it is one of the heaviest portable hard drives we reviewed, weighing 8.1 ounces.

Like most portable hard drives, this one is bus-powered, meaning it uses a single USB cable to deliver power and transfer data. The external hard drive also has a status LED indicator to signify when a data transfer is occurring, illuminating in a different color according to the USB interface currently in use: blue for USB 3.0 and red for USB 2.0.

Transcend offers a three-year warranty on the StoreJet 25M3. This covers parts and labor as long as the damage is due to manufacturing or workmanship defects and not user abuse, modification or accidental misuse. Customer service is similarly decent. The manufacturer's website has a FAQs section and technical resources such as user manuals, drivers and software for all Transcend products. To reach the company directly, the site has an online contact form.
