Overview
A 128GB SDXC card in SanDisk's Extreme line, rated UHS-I U3 and Video Speed Class 30 (V30) with stated read speeds up to 230MB/s and write speeds up to 160MB/s.
This sits between the Ultra and Extreme PRO tiers: faster and 4K-rated compared with the Ultra's U1 spec, but without the PRO line's QuickFlow read ceiling. SanDisk markets the Extreme line as built to withstand temperature extremes, water, shock and rough handling, which is worth knowing for field use rather than desk use.
- 128GB SDXC card
- UHS-I U3 / V30
- Up to 230MB/s read
- Up to 160MB/s write
Who it's for
Works for photographers and videographers who want a 4K-capable card without paying Extreme PRO pricing, especially for use in the field where durability matters. Studio or high-volume shooters who need the fastest possible offload should look at the Extreme PRO tier instead.
