According to Sony, the drives support the USB 3.1 Generation 1 standard, which means that they have theoretical read speeds of 130MB per second. The flash drives will store content like music, video and photos, and will also help transfer content and media from a Mac or Windows desktop to an Android smartphone or tablet and vice versa.
The platforms that Sony's USB CA1-series support include Android, Windows, Mac and Chromebooks. As soon as Sony releases a launch schedule and some pricing information, we will pass it along to you. That could happen next month at MWC, which begins on February 22nd. In fact, that is the date of Sony's MWC media event for which invitations have already been sent out.
