Congratulations on your purchase of a Dynex DX-CRDRD Internal All-in-One card reader/
writer. This card reader provides an excellent solution for directly accessing media cards at
the front of a computer. It is ideal for installation in a 3.5-inch drive bay.
The card reader directly accepts standard media memory cards, such as Secure Digital (SD),
Multi Media Card (MMC), Compact Flash™ (CF), IBM® Microdrive, Memory Stick (MS, MS Pro),
and xD-Picture card™.
The card reader also provides incredibly fast read/write speeds when paired with a CF UDMA
card, Secure Digital High Capacity (SDHC), or a new Memory Stick PRO-HG Duo, letting you
minimize the time you need to transfer files from, and writing files to memory cards. It is
ideal for professional photographers and users of digital single-lens reflex (DSLR) cameras.
It also accepts mini-sized Micro SDHC, Micro SD, and M2 cards without the need for adapters.
