Armor A85 is meticulously equipped with three layers of defense to protect the drive from vital hurts that may happen during daily operations. The internal suspension system makes the first layer of defense to ensure excellent vibration damping function. The second layer applies rubber covering to provide shockproof capability with perfect buffer effect. And the heavy-duty aluminum case creates the third layer to enable incredible pressure resistant protection. Furthermore, the A85 provides the free SP HDD Lock Utility software to enhance better data security with limited access by a password.Specification:* Advanced internal hard drive suspension system* Meet IP68 dustproof/waterproof standard* Pressure-resistant with aluminum casing* Intelligent cable-carry design* Easy to plug and use; no external adapter required* offers SP HDD Lock Utility free software download for full disk encryption* 256-bit AES encryption with SP Widget free download software* Color：Silver * Interface：USB 3.0 / USB 2.0 compatible* Data transfer rates：Max. 5 Gbps (USB 3.0 Mode); Max. 480 Mbps (USB 2.0 Mode)* Power supply：DC5V (Power supplied through USB)* Supported operating systems：Windows 10/8.1/8/7/Vista/XP, Mac OS 10.5.x, Linux 2.6.x* Operating temperature：5℃~ 55℃* Storage temperature：-40℃~ 70℃* Warranty：3 years
