These external storage solutions are ideal for storing data that doesn't require extremely fast transfer rates and offer a convenient solution if you prefer not to pursue the NAS route. Some of these external HDD enclosures have Exos drives that are good for shucking the drives out of, but do some research into what drives they contain, as shucking the drive will most certainly void the warranty, and it's a bit of a minefield determining what drive is actually contained inside.

The 28TB Seagate Expansion HDD is housed in a rugged black plastic case that measures 7 x 2 x 5 inches, with small feet on the bottom of the chassis. Power and USB cable connections are located at the rear of the drive, where you will need to connect the external AC power adapter. Make sure you have ample power outlets available for connecting this device alongside your desktop PC or laptop.

This Seagate desktop drive comes with an 18-inch USB 3.0 cable and a power cable included in the box. Accompanying the purchase of the Seagate drive is the option of using Seagate's Rescue Data Recovery Services software for data backups, which offers a single in-lab attempt to recover the data from the Seagate drive.
