Buffalo's MiniStation Safe (HD-PNFU3 series) is a slim, SuperSpeed USB 3.0, portable hard drive that comes in a patented shock-proof chassis and features Buffalo's new Lock-and-Go feature - thereby protecting your data in two important ways! Firstly, Buffalo gave the HD-PNFU3 a sleek design with an attractive matte finish and Buffalo's patented shock-proof chassis. The second protection comes from Buffalo's Lock-and-Go feature allowing both PC and Mac users to quickly and easily password-protect their data. The MiniStation Safe will stay locked until the correct password is re-entered - no matter where you take it! Want more protection? With Buffalo Tools' SecureLockMobile PC users can software encrypt their device and have the option to keep both encrypted and unencrypted data on the same drive. Files are password protected once moved into an encrypted container and users can choose between 128 or 256 bit encryption (default value is 256 bit). The difference: 128 bit encryption could theoretically be cracked in a billion years; and 256 bit would take even longer - using a super computer! This type of encryption has never been broken and governments and businesses place a great deal of faith that it never will be. The HD-PNFU3 MiniStation Safe brings you the Buffalo quality you know and trust in a small, attractive, and secure package. MiniStation Safe is available with 500GB, 1TB, or 2TB capacities. All capacities are available in black; 1TB capacity is also available in red.
