SD cards are flash memory, which means they have no moving parts and instead rely on electronic chips to store data. SDXC cards, meanwhile, range from 64GB to 2TB and are aimed at professional-level users who require more memory. SDHC bumps this up from 4GB to 32GB, useful for most photographers and videographers. SD cards typically offer 128MB to 2GB in storage capacity, too small for today’s modern cameras with higher resolutions. There are three main types of SD card: SD, SDHC (high capacity) or SDXC (extended capacity). Real-world results are often slower (sometimes a lot slower) so check our guide above for a better idea. ![]() Read/write speeds labelled on SD cards are best case scenarios and often hyped by the manufacturer in order to sell more units. But if you’re planning on shooting lots of high resolution stills or 4K/8K video, you’ll likely want to go bigger (at least 64GB) rather than smaller.Ĭapacity shouldn't be your only consideration – a card's reading and writing speeds are also crucial to storing the recorded media and for a speedy transfer between devices. The larger the capacity, generally, the more expensive the card. It’s important to check your device’s manual to see the maximum card capacity it’s compatible with, as some cameras won’t be able to accept cards over 32GB. When it comes to SD card size, we’re talking these days about how much data can fit onto the memory card in gigabytes (or possibly terabytes). We found its write speed to be a little slow compared to other UHS-I cards in this class range, but it’s good value for money and the V30/U3 class listing means it’s still suitable for up to 4K UHD video recording.Īctual transfer speeds under our testing churned out a write speed of 33MB/s and read speed of 82MB/s not too bad, but the write speed is close to the minimum V30 classification on the label, so that's worth bearing that in mind if write speeds are important to your work. While the higher capacity cards increase in price exponentially, the 633x appears in sizes as small as 16GB, making it suitable for a wide range of photographers and videographers alike who require all kinds of capacities for casual or professional use. However, Lexar is renowned for its memory card line-up and the 633X UHS-I performs well under scrutiny. Since Lexar’s announcement of the world’s first consumer 1TB SD card back in 2019, there have been several manufacturers that have jumped into the game. If you're an Android phone shooter, though, you'll need one of the best microSD cards to expand your phone's memory. Whatever you’re looking for from an SD card, we’ve speed-tested, reviewed and ranked all of the top options right here. That said, a more affordable alternative is the SanDisk Extreme Pro SDXC UHS-I, while the PNY Elite Performance SDXC is ideal for buyers on a budget. We think the best SD card for most photographers is the Transcend SDXC UHS-II U3, thanks to its incredible transfer speeds and impressive durability. In our guide below, we’ve explained how and why SD cards are classified for photographers and videographers, so you can decipher the meaning behind those numbers and letters.īecause actual performance goes beyond labels, we’ve also put our pick of the best SD cards through a range of real-world tests, to determine which is the top performer for your specific requirements. Short for Secure Digital, SD cards are the memory format most commonly found used in consumer cameras, including some of the best mirrorless cameras and the best 4K cameras for filmmakers. ![]() We’ve put together this guide to help you find the ideal SD card for your needs and budget.
