SanDisk Extreme Go micro SDXC card + SD adapter 256GB (For Android Devices, Gaming Consoles, Drones, Action Cams, UHS-I, up to 200 MB/s, V30, 5K, 4K, UHD, Rescue PRO, Class 10, U3) For Amazon

Why I Bought It I needed a reliable, fast microSD card for my drone to record 4K video, take burst photos, and store media without worrying about running out of space. The SanDisk Extreme 64GB card seemed like a good compromise between performance and cost, especially with the SD adapter included. Setup / First Impressions Right out of the box it felt like a quality product — the microSD and SD adapter are solidly built. The branding (V30, A2, U3) and specs (up to ~170 MB/s read) gave me confidence it could handle heavy usage. It was simple to format and install in my devices with no hiccups. Performance / Quality In day-to-day use this card delivers very well. Recording 4K video is smooth with no skipped frames, even in high bitrate modes. Burst shots on my phone and drone are handled cleanly. Transfer speeds from the card to my PC are fast, although write speeds when filling the card near capacity drop slightly (as is common with many cards). Also, depending on the device, you may not always hit the maximum read speed — but performance is still more than enough for most tasks. Pros ✔️ Excellent read speeds make transfers fast and load times short ✔️ V30 / U3 / A2 ratings mean good compatibility for 4K video, apps, etc. ✔️ 64GB is a good size — plenty of space without being too expensive ✔️ Comes with an SD adapter, which is handy for cameras & devices that use full-size SD Cons ❌ Write speeds drop a little when the card is nearly full or under sustained heavy writes ❌ If you have a device that doesn’t support very high speeds, you may not notice the full benefit of 170 MB/s reads ❌ Adapter adds convenience, but full-size SD performance sometimes lags a little behind the microSD slot (depending on adapter quality) Final Verdict A very strong choice for photographers, videographers, drone users or smartphone users who want fast, reliable storage without premium price tags. It offers great all-round performance for 4K, burst photos, and general media storage. If you don’t often push devices to their absolute limits, you’ll be very happy with this card.

This microSD card works perfectly with my Osmo Pocket 3 and handles 4K video with no issues. The speed is impressive up to 190 MB/s so transfers are quick and smooth. It’s very affordable for the performance, and the included SD adapter is handy. Durable, reliable, and a great choice for cameras, drones, or smartphones.

Supersnel!

Acheté en deux exemplaires, très bonne carte SD, rapide et fiable. Utilisée dans un lecteur SanDisk USB 3.2 Gen 1, elle atteint en écriture soutenue 86–87 Mo/s, ce qui est parfaitement cohérent avec les 90 Mo/s annoncés. Aucun ralentissement, aucun problème de compatibilité. Utilisées pour des OS sur Raspberry Pi et Jetson Nano et pour stocker du flux webcam en direct. Aucun souci, très bon débit. Testée sur Linux avec dd en écriture (fichier de 500 MiB puis 5 GiB depuis /dev/urandom, conv=fdatasync), la carte atteint 86,8 Mo/s constants en écriture. Pas de buffer temporaire, pas de throttling : les débits sont stables sur toute la durée. Le contrôleur gère bien les gros fichiers. Les valeurs de lecture n’ont pas été testées ici, mais la promesse de 190 Mo/s sera de toute façon liée à des conditions optimales (QuickFlow™ activé + lecteur propriétaire SanDisk PRO). Pour une carte UHS-I V30, les performances sont quasiment maximales. Très bon choix pour un usage exigeant, y compris en 4K ou pour transfert de gros fichiers.
