Packaging and Contents:


The Armor A66 comes packaged in an eye catching white, orange and purple box. The front advertises key features like the drive's 2TB capacity, USB 3.2 Gen 1 interface, military-grade shockproof protection and water resistance. The back of the box provides a bit more information, including the Armor A66's specifications, package contents and key features. Inside the box you'll find the drive as well as a USB 3.2 cable.

Physical Features:

Like Silicon Power's other Armor series hard drives, the Armor A66 is a bit on the large side. The 1TB and 2TB versions of the drive measure 139.2mm x 96.0mm x 16.2mm and weigh in at 209g. The 4TB and 5TB versions are slightly thicker (24mm) and tip the scales at 328g. The extra bulk is primarily due to the rubber bumper that surrounds the drive and protects it against drops and water. In addition, it can be used to store the USB cable when not in use.


The Armor A66's top and bottom panels are constructed out of lightweight, black plastic. Underneath the top panel, the drive also has a multicolor LED which lights up red or blue, depending on the USB connection type. This indicator also flashes to show when data is being transferred.

Along the back, you can see the Armor A66's SuperSpeed USB 3.2 Gen 1 interface. This full size connector not only transfers data but provides power for the drive. The rubber bumper also has a plug that, when placed over the USB connector, keeps water out of the drive.

The Armor A66's protective outer bumper also serves as an internal anti-collision suspension system that reduces impact force and increases shock-absorption. According to Silicon Power, the drive is military-grade shockproof and meets the MIL-STD 810G Method 516.6 Procedure IV drop test requirements.

Using CrystalDiskInfo, you can see that Silicon Power has used Seagate's ST2000LM007 hard drive. This slim 7mm drive features a SATA 6.0Gb/s interface, 128MB cache and a 5400 RPM rotation speed.
