Two-pack USB 2.0 card readers

This two-pack provides two external USB 2.0 card readers in black. Each unit reads SDHC, SD, MMC II, RS MMC, Ultra II SD, Extreme SD, Extreme III SD, MiniSD, MMC Micro, Micro SD and T-Flash with an adapter. No external power is required and the readers are designed for convenient carrying.

Suits legacy Windows and Mac users

The readers work with Windows 98, ME, 2000, XP, Vista and Windows 7 as well as Mac OS 9.0 or higher. They are not for systems that only offer USB 3.0 or newer ports without backward compatibility. Buyers who need internal installation or support for newer card formats such as CFexpress should look elsewhere.

USB 2.0 interface

The single specification that decides fit is the USB 2.0 interface. Data transfers operate at USB 2.0 speeds, so the reader will not saturate faster buses. Verify that the host computer provides a USB 2.0 or compatible port before purchasing.

Questions about this item

Does the 2-pack include any cables or adapters for MiniSD and MicroSD cards?

The package contains two black USB 2.0 readers; MiniSD, MMC Micro, Micro SD and T-Flash cards need their own adapters, which are not supplied.

Both readers in the pack are identical — is there any reason to choose one over the other?

Each unit is the same VCR-339-BK model with USB 2.0 interface and identical card-slot support, so either reader works for the same range of SD, SDHC, MMC and adapted smaller formats.

What transfer speed can I expect when the reader is plugged into a USB 2.0 port on a Windows 7 or Mac OS 9.0 machine?

The reader uses the USB 2.0 interface, so real-world throughput will be limited by that bus rather than the card's own rating.
