Buffalo has this week revealed the latest additions to its MiniStation line of portable drives, the HD-PZU3 Series models which feature USB 3.0 connectivity, 256-bit AES hardware encryption, and a rubber case and internal shock-absorption system offering high impact resistance (the HDDs meet the US military drop-test standards MIL-STD-810F 516.5).

Buffalo's rough and tough drives measure 89 x 18 x 128 mm, they weight 230 grams, have a built-in USB cable, and are backed by a one-year warranty. The HD-PZU3 Series will debut in mid-March with 500 GB (~ $198) and 1 TB (~ $252) HDDs colored in 'Deep Red', 'Indigo Black' and 'Dark Silver'.
