SanDisk Extreme 512GB microSD Card UHS-I V30 SDSQXAV-512G-GN6MA

With 512 GB on a single card, you can keep long video sessions, large photo libraries and offline media in one place without constantly clearing space. That matters most on trips and shoots where you can't stop to offload files. Fewer card swaps also means less risk of mixing up or losing footage. For anyone moving up from a smaller card, the jump to 512 GB makes a noticeable difference to how you shoot and store.

A read speed of up to 190 MB/s means copying a day's footage or a full photo folder to your computer takes noticeably less time. That's useful when you're backing up after a shoot, editing on a laptop or moving files between devices. Actual speeds depend on the card reader and device you use, so a fast, compatible reader helps you get the most out of the card's read performance.

Write speeds of up to 130 MB/s help the card keep up when your camera or drone is saving data quickly, such as high-resolution photo bursts or high-bitrate video. A faster write speed reduces the time your device spends buffering, so you're ready for the next shot sooner. It's a practical advantage for fast-moving subjects, sports and outdoor action, where timing counts and you can't afford to miss a moment.

The V30 video speed class and U3 rating guarantee a minimum sustained write speed of 30 MB/s, the benchmark many cameras and drones specify for high-resolution video recording. Sustained speed is what keeps recordings stable over long clips, not just in short bursts. Class 10 is also listed, which is useful for older devices that check for it. Always check your device's manual to confirm which speed class it needs.

This card uses the UHS-I bus, the interface supported by a wide range of smartphones, tablets, action cameras, drones and handheld consoles. That makes it a flexible choice if you switch the card between devices or upgrade gear later. Before buying, check that your device supports 512 GB microSD cards, as some older models have lower capacity limits. The card's gold/red colour also makes it easy to spot in a bag or case.

SanDisk Extreme is one of the most recognised memory card lines, widely used by photographers, videographers and mobile users. Choosing an established brand gives you confidence in consistent quality and clearly labelled speed classes. The model number SDSQXAV-512G-GN6MA lets you verify exactly which card you're getting. The manufacturer does not list additional durability ratings in the specifications provided here, so we haven't included any.

This card suits action camera and drone users recording long video sessions, Android phone owners who want to expand storage, and photographers who shoot in bursts. Travellers will appreciate having enough space for a whole trip on one card. Handheld gamers can also store a large library. If you need high capacity, fast transfers and solid video ratings in one card, it's a great deal for the storage you get.
