SanDisk Extreme PRO SD UHS-II V90 (128 GB)
A pro-tier UHS-II SD card with the V90 speed guarantee and 300MB/s reads, made for high-bitrate 4K/6K/8K internal recording where sustained write headroom matters. The V90 rating is the whole point — it's the safest class for demanding codecs. Skip it if your camera only has a UHS-I slot, since you'd pay the V90 premium for speed the body can't access.
