The HDD HB is a new portable drive from Sony. The drive is a bit bulky but it has its reasons...
It comes with a removable silicone casing that protect it from shocks and dirt.
This casing can be removed completely if you want to use the drive in its more compact form, which is still not as compact as other portable drives on the market.
The casing has two lids that cover the drive's two ports.
The HDD HB has one Thunderbolt port and one USB 3.0 port.
The drive is available in 2TB and 1TB capacities that are slated to cost $273 and $189, respectively.
Sony says the HDD HB is designed for professionals who need to travel and work in rough environments.
