Compact USB 2.0 card reader for mobile storage

The SanDisk SDDRK-121-A46 connects to a PC through a USB 2.0 port and accepts microSD cards with the included SD adapter. It also supports Memory Stick media for older devices. The small form factor suits travelers who move photos or documents between phones, cameras and laptops without needing a bulky hub. No external power is required.

Steady throughput for small file batches

Because the interface is limited to USB 2.0, sustained transfer rates stay within that bus ceiling rather than peaking briefly. Copying a few gigabytes of JPEGs or documents proceeds at a consistent pace without the slowdown seen on faster drives that saturate the controller. The reader is practical for incremental backups, not for moving large video libraries quickly.

Passive cooling keeps operation silent

The unit has no fan and draws power only from the USB port, so it adds negligible heat to a workstation. In normal use it remains barely warm to the touch and produces no audible noise. The low power draw means it will not strain laptop batteries or exceed the current limit of standard USB ports.

Questions about this item

Does the USB 2.0 interface on the SDDRK-121-A46 draw enough power to run warm during long transfers?

The reader is bus-powered over USB 2.0 and stays cool because it has no moving parts or active components that generate noticeable heat.

What card slot must my device already have to use the included SD adapter with this reader?

Your device needs a full-size SD card slot; the bundled adapter converts the microSD card to that form factor.

Will the SDDRK-121-A46 read the older Memory Stick cards I still have from a previous camera?

Yes, the specifications list Memory Stick support alongside SD, so legacy Memory Stick media will work directly.
