Wise SDXC UHS-II V90 Mk-IV 256GB Memory Card – Product Overview
The Wise SDXC UHS-II V90 Mk-IV 256GB Memory Card combines a SDXC form factor with the UHS-II bus and V90 video speed rating. It is intended for professional image capture and fast file transfer in equipment that supports its exact media format.
Recording Performance
Its V90 classification is a meaningful sustained-write guarantee: 90 MB/s, distinct from peak write speeds of up to 280 MB/s and read speeds of up to 300 MB/s. That distinction matters when selecting cards for continuous recording.
The V90 performance class targets high-data-rate camera capture, including compatible cinema and professional stills workflows; recording eligibility still depends on the manufacturer's camera requirements.
Generation, Capacity and Workflow
This exact SKU is from Wise's SD-N Mk-IV range. It is a different generation from the similarly named earlier SD-N128 card and has its own performance specifications.
The stated 256GB nominal capacity is expressed in decimal units; actual formatted free space is lower. Wise's five-year limited warranty is subject to manufacturer terms and any applicable registration requirements.
