Product Description

Size: 640GB | Color: Gold

Silicon Power Armor A50 features hairline treated aluminum construction. The hairline surface is fingerprint proof and its raised imprint logo gives off an elegant aura, perfect for the business professional. The A 50 is in compliance with US MIL-STD-810F (transit drop test), it was tested for (1) free fall drop directly onto concrete or hard surfaces; (2) specific height free fall test (about 4 ft); (3) product's 8 corners, 12 sides and 6 surfaces all must pass free fall tests. Silicon Power's Armor A50 passed the test with ease, ensuring the data stored is safe from damage! Armor A50 utilizes the USB 2.0 interface that features a maximum of 480Mb / sec transfer rate and is backwards compatible with USB 1.1. Made convenient for users, there is also an One Touch backup button and LED status light to indicate current transfer modes.

Color Name: GoldSize Name: 500GB Verified Purchase
While I have had problems with other plug and play hard drives, this one has been great. Not once has there been an issue- even though I am not the most delicate with things like this. This hard drive seems to be made to stand up to being moved around alot, unlike most portable hard drives (I actually keep it in my purse). If you are looking for durability, as well as convenience, I would highly recommend this hard drive.
