Introduction

Nowadays, external hard disk drives are virtually indispensable as secondary storage space for computers with low disk space, as a data backup device, or as a simple way to carry around big amounts of data. Among the portable models (usually based on 3.5 inches drives and with no need for an external power supply), the Seagate Seven stands out because of its thickness of only 7 mm and the robust design. Let’s look a little closer at it.

The highlight of the portable external hard disk drive Seagate Seven is its main design feature: the 7 mm thickness with a steel case. It also uses an USB 3.0 interface, which promises a good performance. As a comparison, one of the thinnest models we tested previously was the Seagate Backup Plus Slim, which is 13 mm thick, almost twice the Seven’s.

The product is available only with 500 GB because it uses a Seagate Laptop Ultrathin (ST500LT032) 5 mm thick hard disk drive internally, which does not offers higher capacities. This hard disk drive works at 5400 rpm and has 16 MiB cache, with SATA-600 interface.

The Seven (which part name is STDZ500400) costs around $98 USD.

Now, let’s take a closer look at the Seagate Seven.
