PROGRADE DIGITAL EXPANDS FAMILY OF USB 3.1, GEN. 2
WORKFLOW READERS WITH ADDITION OF DUAL-SLOT FOR SD™ CARDS
Get Simultaneous Transfer of Files from Cards in Both Slots

SAN JOSE, Calif., January 04, 2019, 8:00 am Pacific—ProGrade Digital, founded with a mission to provide the highest quality professional grade digital memory cards and workflow solutions, introduces and announces immediate availability of its newest product, the SD™ Dual-Slot USB 3.1, Gen. 2 Card Reader, $79.99 USD. As with all other ProGrade Digital USB 3.1, Gen. 2 workflow readers, files on each card transfer simultaneously at speeds of up to 10Gb/s (1.25GB/s).
“Many of today’s professional cameras have two SD slots, so it is only natural that ProGrade Digital’s newest USB 3.1, Gen. 2 workflow reader be a dual-slot for SD cards,” said Wes Brewer, founder and CEO of ProGrade Digital. “Based on the successes of earlier workflow readers, we know that our patent-pending magnetic base, compact rugged design and inclusion of two USB cables (Types A to C and C to C) really resonates with both professionals and prosumers. The dual-slot reader for SD cards provides just one more choice for our customers.”

The actual download speed is limited by the card itself, which for the fastest UHS-II cards is 312MB/s – for dual cards that’s 624MB/s or around half the maximum USB3.1 Gen 2 capacity. I use my reader via a USB 3 card in my Mac Pro. That has a ~640MB/s max rate, so two fast SD cards are still just about limited by card speed, even on my older kit. Of course, real world use with physically loading cards, and the software you use will all affect how fast you can get stuff from your cards. With this device, any bottle necks are not coming from the reader.
