- SanDisk also expanded Extreme PRO SDXC UHS‑II cards to 2TB in V90 and V60 tiers, with V90 now shipping and the CFexpress 4.0 cards plus V60 SD slated to arrive in the third quarter, according to BenchLife.
- SUNEAST’s ULTIMATE PRO SILVER cards use TLC NAND in 512GB, 1TB, and 2TB sizes and carry a five‑year warranty rated at 600 TBW per terabyte.
- SUNEAST lists up to 3,700 MB/s read, up to 3,200 MB/s write, and sustained writes of 800 MB/s or 1,550 MB/s by capacity, which helps prevent dropped frames during long 8K RAW recording.
