Performance

The A2 rating ensures fast app loading on smartphones and handheld consoles. The 190MB/s read speed loads games noticeably faster than older U1 cards. The V30 write speed is sufficient for 4K video at up to 60fps but not for 8K recording (which requires V60/V90).

“I installed this in my Steam Deck and can now keep my entire library installed — 30+ games with room to spare. Game loading times are excellent thanks to the 190MB/s read speed. I also use it in my DJI Mini 4 Pro drone for 4K footage. The card is reliable but gets warm after 30+ minutes of continuous 4K recording.” — JD.com user

FAQ

Q: Is this card fast enough for 4K video recording? A: Yes, V30 (30MB/s minimum write) is sufficient for 4K@30fps and 4K@60fps H.264/H.265. For 8K recording, you need V60 or V90 cards.

Q: Can I use this card as a laptop’s primary drive? A: Not recommended as an OS drive. While fast for microSD, random IO performance and latency are much worse than even a basic SATA SSD. Use for storage expansion only.

Q: Does the SanDisk 1TB work with Nintendo Switch? A: Yes, the Switch supports microSD cards up to 2TB. This 1TB card works perfectly with Switch and will hold 30-50 digital games depending on size.
