SD cards and microSD cards are used for storage in multiple devices, like Android phones, Windows PC, cameras, and so on. Unfortunately, many fake SD and microSD cards are floating around the internet. Even a reputable online marketplace like Amazon cannot avoid these fake SD cards being marketed to unsuspecting consumers.

Overview of Free SD Card Speed Test Tool

SD card speed test tools can help you run an SD card speed test to check if it is a fake SD or micro SD card by testing its speed and capacity.

In order to write this article, we spent a month testing 8 of the most popular free SD card speed test tools on the market on Windows, Mac, and even Android devices. If you are facing SD speed-related issues, pick a tool that suits you.

2. FakeFlashTest

FakeFlashTest runs an SD card speed test by providing a "quick size test." This function writes and reads 512 bytes of data in random sectors on the card, which allows for faster test results, especially for high-capacity cards. But it can only test the real-time writing and reading speed, not the peak speed.

Review from MajorGeeks: This is a pretty slick and simple tool for verifying that you have the memory size you paid for. But that is not all; it can help prevent corruption.

3. H2testw

H2testw is a powerful free software that can test USB flash drives and hard drives and report whether there are current problems, as well as detect counterfeit SD cards and USB flash drives. The problem is that it was developed in 2008 when SD cards were smaller. On newer high-capacity drives, a scan with H2testw can take hours or even days, especially when they are also slow to write. But it is generally safe and reliable.

Blackmagic Disk Speed Test measures and verifies disk performance using standard methods. It fills the free space on the disk with data samples, then evaluates and tests the read and writes speed of the disk. Blackmagic Disk Speed Test is ideal for benchmarking hard drive performance for high-quality video.

6. SpeedOut

SpeedOut can quickly measure the sequential read and write speed of flash drives/SD cards. Scores are not affected by the drive's file system. To start testing, you need to first select your USB drive from the drop-down list. SpeedOut will then run four read-and-write tests and display the average of each test. SpeedOut's testing process does not overwrite any files, and the SD card/flash drive does not need to be formatted to run the test.

Check the review from AlternativeTo of this tool below to learn more:

Review from AlternativeTo: It uses low-level technology, which allows you to know REAL drive speed without slowdowns caused by File System.

7. ChipGenius

ChipGenius does not write any data to the SD card. This tool looks for manufacturer information as well as capacity information programmed into the target SD card storage. It cross-references this information with its database. After it completes the process, it will report the results back to you. For example, if you purchased a 64GB Class 10 SanDisk SD card, but ChipGenius reports that it is actually an 8GB Class 6 Emtec, then you know you have been scammed. The main benefit of this tool is that the testing process is much faster. However, many shady sellers today know how to cover their tracks. That's why ChipGenius might not recognize every fake card circulating online.


The table below can help you learn more:

Features ChipGenius
Compatibility Windows
Data Tested The manufacturer information and the storage information
Devices Supported SD cards, USBs
  • No download is required
  • Recognize and check nearly any USB device
  • No option to export reports
  • Requires a 32-bit and 64-bit setup

Here is a view from TrishTeck about this tool:

Review from TrishTeck: One possible use of ChipGenius could be to identify fake devices that we often find on eBay. No matter what the outer package shows, you can always know about the chip inside a USB device using ChipGenius.

8. AJA System Test

AJA System Test can help to check SD card speed on Windows and Mac for free. Not only is this tool easy to use, but it also provides detailed graphs to view the performance of the SD card. If there are large fluctuations, there may be a problem with the SD card. Of course, if you're testing an old card, this could also be a sign that it's starting to go bad.

We've browsed eight free SD card benchmark apps here, and this article details their features, including their compatibility, pros, cons, and so on. Choose one based on your needs.

You can move partitions around, resize them, defragment, and more, along with the other tools you'd expect from a cloning tool.
