Physical Features:
Compared to Silicon-Power's other portable hard drives, the Armor A15 is a bit on the large side. The drive measures 136 x 82.5 x 19.8 mm and tips the scales at a whopping 200g. The extra bulk is primarily due to the black and green anti-shock rubber casing which covers most of the drive.
On top of the Armor A15 you can see its OneTouch quick backup button, which lets users instantly synchronize data with their computer. This button also has a bright blue LED that will light up when the drive is powered on and flash to show when data is being transferred.
Along the back, you can see the Armor A15's SuperSpeed USB 3.0 interface. This connector not only transfers data but provides power for the drive..
I wasn't able to crack the Armor A15 open. However, using CrystalDiskInfo, I was able to see what hard drive was in the enclosure. Looking at the screenshot below, you can see that Silicon Power has used Seagate's Momentus ST1000LM024 hard drive. This drive features a SATA 3.0Gb/s interface, 8MB cache and a 5400 RPM rotation speed.
