Transfer your data files at speeds of up to 1.25GB/second using the ProGrade Digital SD Dual-Slot Workflow Reader. Indispensable for cinema, video and photography workflows where large volumes of data files are the norm, this reader provides simultaneous rapid and efficient transfer of data from cards in both slots. Portable and compact, the ProGrade Digital SD Dual-Slot reader features an industry-first magnetic base that pairs to an included metal plate. Affix the small metal plate to laptop or host device then safely and efficiently transfer files - whether working in the field or studio. Two included 18" USB connector cables (one A-to-C and one C-to-C) ensure device interoperability. An LED activity light indicates when transfer is complete.
