![]() ![]() Why bother? Well, if you are accessing or storing video or other real-time demanding applications, you want a drive that can keep up with the read and write demands of those applications. While you’ll find the occasional damaged card, most are legitimate.Blackmagic Disk Speed Test is a tool designed to test the speed of your drives. Amazon is full of fakes, so read the reviews carefully before ordering.Īnother option is to buy from a brick-and-mortar store. For example, if you’re shopping on Amazon, buy directly from Amazon or the SD card brand’s Amazon store. Ideally, stick with the following brands:Īvoid buying from third-party sellers. You’re definitely not getting a 256GB SD card for $5 or lower like you might see advertised on or similar sites. Unless it’s a site and brand you trust that’s currently having a major sale, such as Black Friday, you’re not going to get a reliable SD card for 50% off or more. Second, skip deals that sound way too good to be true. How can I be sure I’m buying a real SD card?įirst, stick with reputable sites and brands. I could use all three of these tools fully in the free trial version. Fake SD cards often have errors, which reduces the capacity and speed even more. You can also use Error Scan and File Benchmark tools to further check if the card has any issues. The toolkit is actually a mixture of six tools. This enables much faster test results, which is particularly ideal for larger capacity cards. However, FakeFlashTest speeds up the fake SD card test by offering a “Quick Size Test.” This function writes and reads 512 bytes of data at random sectors across the card. This tool is very similar to H2testw in that it writes data to your SD card in order to determine read/write speed and capacity. If you’re looking for something a bit speedier than H2testw, consider FakeFlashTest. H2testw is only available on Windows however, it can be run on Linux and Mac via a virtual machine. ![]() After the first run it will give users the option to use English as the default language.

As such, the website that hosts the fake SD card test software, as well as the software itself, is in German. H2testw was originally developed by a German software engineer. While H2testw will work on any size drive, it may take a bit longer to complete the test. This means that the software has not been optimized to be used on larger-capacity drives. The only downside to H2testw is the fact that it is quite old. This reliable tool is able to test the true capacity of an SD/microSD card, as well as the read/write speed of the drive. H2testw has been around for a very long time and for good reason. Before you order a large batch of super cheap SD cards, buy one and test it to make sure you’re getting what you pay for. Fortunately, there are a number of free tools that can test the speed and capacity of your cards. In some cases the card corrupts data, rendering it useless. For example, a card is advertised as 256GB however, it really only holds 4GB. The most common scam is falsely stating the card’s capacity. While the offers are tempting, these cards often only last for a few weeks or months before they stop working completely. ![]() Either way, they scam buyers in one of two ways: by offering a brand name at an unbelievable discount or by offering a generic brand with a crazy amount of storage for nearly nothing. ![]()
