Sony's new HDD models offer dual Thunderbolt and USB3.0 interfaces for compatibility with a range of widely used computers and devices. These newest entries in Sony's portable storage line-up include PSZ-HB1T, a 1TB model and PSZ-HB2T, a 2TB model.

The PSZ-HB2T offers transfer speeds of up to 122MB/s, while the PSZ-HB1T can read and write at up to 120MB/s.

Another feature of Sony's shuttle drives are their durability. The devices are covered in silicone rendering them shock-resistant, with an internal architecture optimized for use in rugged situations. The drives are tested to withstand drops of up to 2.0m. Furthermore, the interface ports have silicone covers, offering a high level of splash and dust resistance.

While the dual Thunderbolt and USB ports secure data transfer against unexpected problems to one port, with Memory Media Utility software, the reliable shuttle drives offer various functions. The software allows users to manage their portable storage with features such as device information display, reformat for quick erasure and re-use, backup to multiple locations and disk status check to determine optimum replacement time. Memory Media Utility for PSZ series will be available for download in May at http://www.sony.net/mmu/.

Sony's shuttle drives are designed so multiple units can be stacked, allowing increased airflow and effective cooling.

The HDDs come in a streamlined hard case, which neatly packages all of the included cables and offers space for detailing the contents of the drive. This allows for protection during transportation, easy handling and organized shelf archiving.

The new Sony PSZ-HB2T and PSZ-HB1T HDDs are planned to be available in May 2015. Sony did not disclosed pricing details.
