Zalman unveiled the ZM-HE400 and ZM-HE135 (pictured in that order). Available in silver and black, the ZM-HE400 measures 146 x 80.8 x 14 mm (LxWxH), with room for a 2.5-inch SATA 6 Gb/s drive, which it then connects to the host over USB 3.0, but not before a physical authentication layer. The enclosure features a felt-touch number-pad and a small LCD display, that let you set and authenticate a numerical password before accessing the 256-bit AES-encrypted contents of the drive. The ZM-HE135, which measures roughly the same, featuring the same 2.5-inch SATA 6 Gb/s bay that connects to the host over USB 3.0, lacks a physical authentication, but still encrypts your Precious using 256-bit AES, and authenticates on mount.
