USB 3.0 vs. Thunderbolt war truly begins. Toshiba is, for the moment at least, staying friendly with the USB side, announcing updated versions of its STOR.E external HDDs, both packing Superspeed tech. On the smaller side is the ALU 2S, packing a 2.5-inch HDD internally that has up to 1TB on platters. If you need a little more you can step up to the Steel S, another external unit containing a 3.5-inch HDD with up to 2TB of storage. That one, unfortunately, will require an external power supply, while the littler ALU 2S will get by with only a USB cable. Both feature metal exteriors, increasing their usability as impromptu bludgeons, and both are slated to start shipping before this first quarter is through -- which should mean any time now.
