Fast, reliable, and plenty of space
This SD card works perfectly with my Canon R50, even when shooting 4K video. The speed is excellent, with fast write and transfer times, so I never worry about lag or dropped frames. It handles burst shooting and large RAW files without any issues.The 256GB capacity is a huge plus, giving me tons of space for both video and high-resolution photos without needing to swap cards constantly. I’ve used SanDisk cards for years and they’ve always been reliable. Definitely worth the price for the performance and peace of mind.

Excellent value for money and memory size
Excellent value for money, functionality, quality with older camera I saved because of this media, super easy to install in camera and fast enough to use camera much better and longer video time besides more pictures

Reliable, reasonably priced, great for backup
Best SD card out there. I use these in my Nikon cameras. I transfer the images to my computer hard drive and when they approach capacity I just buy new cards. I never delete the original images as I prefer to save them as backups.

Achetée pour mon Canon EOS R50, cette SanDisk Extreme PRO 64 Go fait parfaitement le job. Les vitesses de lecture annoncées à 200 Mo/s sont bien là, ce qui permet un transfert rapide des fichiers sur l’ordinateur. En écriture, la classe V30 et UHS-I U3 garantissent une bonne fluidité, aucun ralentissement en rafale ou en vidéo 4K.SanDisk reste une valeur sûre, je n’ai jamais été déçu par cette marque. La carte est fiable et performante, idéale pour stocker des photos en RAW et des vidéos haute résolution sans souci.Un excellent choix pour les photographes et vidéastes qui cherchent une carte rapide, efficace et abordable.

Mükemmel, daha önce 512gb almıştım ama veri okuma hızı 170’ti. Bu ürün hem ucuz hemde diğer ürünümden daha iyi. Harika bir FP ürünü diyebilirim.

I’ve never had problems with SanDisk SD cards, my only concern is their authenticity. I feel buying from Amazon is a better option.
