Little Speed Reader

Sonnet’s Dio Pro CompactFlash and SDXC USB 3.0 Media Reader quickly transfers files from CompactFlash (CF), SDXC and SDHC™ memory cards to your computer on location, in the studio, or at the office. With one slot each for CF and SD media, Dio’s ability to transfer data from the fastest professional memory cards at much higher speeds than USB 2.0 card readers are capable makes for a significantly more convenient and efficient workflow. This handy device also supports concurrent and card-to-card file transfers.

SuperSpeed USB 3.0Dio can ingest files from your pro memory cards up to four times as fast as other card readers. What's its secret? This Sonnet reader exploits its 5.0 Gb/s SuperSpeed USB 3.0 interface to deliver superior performance with suitably equipped computers. Dio is UDMA6-enabled and UHS-I-compliant for CF and SD media, respectively. As a result, Sonnet’s high-performance memory card reader transfers data from currently available CF cards at up to 70 MB/s, while it supports at full speed the fastest available SDXC and SDHC memory cards, as well as future cards up to 104 MB/s.

This little, rugged Sonnet pro media reader is compatible with Windows® desktop and laptop computers with USB 3.0 ports. Got a Mac®? It is also compatible with Mac® Pro computers with Sonnet’s Mac OS® X-compatible Allegro USB 3.0 PCIe adapter card installed, and MacBook Pro computers using Sonnet's Mac OS X-compatible USB 3.0 ExpressCard/34 adapter. No USB 3.0 ports at your disposal? Dio is backward compatible with USB 2.0 connections, too.
