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.

These are GREAT SD cards. And excellent value.
