Lexar CFexpress 4.0 Pro Silver — R3600/W3300 high-speed 1TB

The Lexar CFexpress 4.0 Pro Silver delivers high-performance storage tailored for modern cinema cameras and high-resolution DSLRs. It provides a 1TB capacity (per the product title) and targets demanding photo and video capture workflows.

High-speed performance for capture and transfer

The card is described with very high read and write figures. The product title specifies read speeds of R3600 and write speeds of W3300 for the 1TB model.

For the fastest transfers, use an appropriate CFexpress Type-B reader. Lexar indicates the highest transfer speeds are achieved only when using an CFexpress Type-B reader that displays a boxed USB logo.
