MSD TESTER is a portable memory card testing device.
With it, you can easily check the memory card for compatibility with audio and video recorders, determine errors, timeouts, as well as memory card power consumption at different read/write speeds.
Test your SD card and make sure it’s compatible with your device!
Choosing the right SD card is not always as easy as it might seem.
There are different names, such as SDHC and SDXC, and designations for speed and memory capacity, mixed together in a mess of technical jargon.
It is not enough just to choose the type and size of the memory card. Many modern digital devices impose certain requirements on the values of the speed and power consumption of the data storage devices used in them.

Get the most out of your digital devices
MSD Tester allows you to quickly test your memory card and determine the battery life of your device, that mainly depends on the current consumption of the memory card.
Check the parameters stated by a memory card manufacturer
The marking on the front panel of the memory card has not always been confirmed by independent tests.
MSD Tester determines the real parameters of a memory card, indicating not only the speed of linear information recording, but also the speed of random small-block read/write. The latter is crucial for miniature audio and video recorders.


Portability and ease of use
Simply insert the memory card into MSD Tester and wait for the test results on the display.
The MSD Tester is designed with the convenience of everyday use in mind, with a robust body, a user-friendly control button and an OLED display. MSD Tester is completely self-contained, but can also be controlled via PC application.
- Designed for MicroSD/SD cards.
- Supports SDHC / SDXC cards.
- Battery capacity: 2200 mAh.
- Battery life up to 6 months.
Price: 220 $
