It’s common to find XQD card slots in camcorders, but Nikon’s Z series of mirrorless consumer cameras also caused a stir when they initially came out with a single XQD slot.ĬFExpress Types A and B – what’s the difference?ĬFExpress Types A and B are both fundamentally the same type of card, but physically and in compatibility terms they’re actually pretty different. They’re physically thicker and stronger than SD cards, and have generally been used in professional video and filmmaking applications. Sony developed the XQD format as a faster, higher-capacity and more reliable alternative to SD cards. UHS-I cards have a maximum bus speed of 104MB/s, while UHS-II cards have a maximum bus speed of 312MB/s. Some cameras have two card slots, one may be UHS-II and the other just UHS-I. The fastest SD and microSD cards use the UHS-II bus standard – however, to actually get the benefit of the extra speed, your camera or other device needs to be UHS-II compatible. These are standards for SD and microSD cards, and refer to the cards’ bus speeds (file transfer speeds). They’re slower than SD cards, but can still generally store large capacities of information for their size. The smaller counterpart to SD cards (as you might have guessed), microSD cards are more commonly used in smartphones and tablets, as well as some drawing tablets, as opposed to cameras. Some devices will only support cards up to a certain capacity. SDXC cards have a capacity of at least 64GB, going up to 1TB. The older SDHC cards have a capacity of between 4GB and 32GB. The standard SD type is no longer found in stores, so you typically have the choice between SDHC or SDXC. Standard-sized SD cards come in three main types: SD, SDHC and SDXC. These are the most common types of card used in camera it's highly unlikely that your camera won't accept some form of SD card. ![]() Here's a quick explainer of the different card types you’re likely to encounter, all of which we’ve included in this guide. It's simpler than it appears: all this means that when you're choosing the best memory card for your camera, smartphone or tablet, you’re selecting one that actually physically fits it.Ĭheck with the manufacturer of your device if you're unsure the information will be floating around somewhere. ![]() However, there’s a built-in error correcting code here to detect and correct any transfer errors.Īll the different acronyms and numbers involved in memory cards can be pretty overwhelming for the unaccustomed. Actual performance of course is affected by camera hardware and software, as is the case with any card. Specification is also solid for a budget card here we get read speeds of up to 120 MB/s and write speeds of 60 MB/s. However, even the higher capacity offerings that may appeal to semi pro DSLR users – such as this CompactFlash 800 series – are hardly expensive for what’s on offer.Ĭapacities run from a standard 32GB up to a slightly more impressive 256GB. While it may not be as recognisable to the casual observer as competing card brands, Transcend is one of the longer-term players in the market – and, usefully, still makes many low-capacity cards, holding obvious appeal for those on tighter budget. As you might expect, faster cards with higher capacity will come with higher price tags. We also go through speed classes, so you can be sure you're getting the right card for your needs.Īlso, the vast majority of cameras will accept an SD card, so we've put those first in our guide, with plenty of different speed and capacity options. If this already sounds overwhelming then don't worry – we've put together an explainer on types of memory card where we run through it all. You also need the right card to physically fit in your camera, as different models have different slots – some will take CFExpress, XQD, CFast or CompactFlash, all of which are different physical shapes. The amount of speed and capacity needed will vary depending on what the user plans to shoot – high-quality video in resolutions of 4K and up has much more intense data demands than shooting the odd still image, and needs a card that can keep up. Having enough space to take plenty of shots without changing, and the speed to transfer images and videos off quickly, is a huge quality-of-life improvement. It may sound mad, but a good, high-capacity and high-speed memory card could be a great Christmas present for the photographer or videographer in your life.
