Lock-&-Go Buffalo™ gave the HD-PNFU3 a sleek design with an attractive matte finish & Buffalo’s patented shock-proof chassis. The second protection comes from Buffalo’s new Lock-&-Go feature allowing both PC & Mac users to quickly & easily password-protect their data. The Mini Station™ Safe will stay locked until the correct password is re-entered – no matter where you take it! Want more protection? With Buffalo Tools’ Secure Lock Mobile PC users can software encrypt their device & have the option to keep both encrypted & unencrypted data on the same drive. Files are password protected once moved into an encrypted container & 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; & 256 bit would take even longer – using a super computer! This type of encryption has never been broken and governments & businesses place a great deal of faith that it never will be. A small, attractive, & secure package Buffalo’s Mini Station™ Safe occupies minimal space & offers USB (Universal Serial Bus) 3.0 bus-powered mobile storage for your data & for your on-the-go lifestyle.
