Sony's newest hard disk drives expand its line of portable storage choices, delivering faster speeds, greater connectivity, reliability and durability.

The new 1TB and 2TB HDDs are designed for any professional use requiring memory card backup.

Improving on Sony's previous HDDs, the new dual interface models support USB Type-A connectivity using a tethered cable, in addition to a USB Type-C port. The drives are pre-formatted in exFAT, and allow for data transfer up to 138MB/s (read/write).

The rugged shuttle drives' rubber damper design offers durability, making it shock resistant and capable of withstanding a drop of up to 6.5 feet. The HDDs are splash-resistant (IPX4 rating) and dust resistant (IP5X rating). A silicon lid protects the connection terminals from dust and water. The PSZ-HC1T and PSZ-HC2T come packaged in a library box for additional protection during shipping or storage.

Sony's free Memory Media Utility software offers additional protection by providing a record/rewrite life indicator, simultaneous content backup to multiple destinations, a re-formatting tool and more.

The new HDDs, models PSZ-HC1T (1TB) and PSZ-HC2T (2TB) are planned to be available in July. Siny has not announced their pricing yet.
