Ritz Gear 128GB CFexpress Type B Card - High-Speed 4K Video Ready

Our review of the Ritz Gear 128GB CFexpress Type B card finds it well suited for professional shooters and advanced hobbyists who need reliable, high-bandwidth storage for 4K RAW video and fast burst photography. The single biggest reason to buy is the card's combination of very fast transfer rates and a rugged design: with tested speeds up to 1700 MB/s read and 1100 MB/s write when used with a PCIe host adapter, it substantially reduces offload times and keeps cameras writing smoothly during continuous recording. That makes it a practical choice when minimizing downtime and avoiding dropped frames matters.

Key Features

• Next-generation transfer: Tested read speeds of up to 1700 MB/s accelerate file transfers to a workstation when paired with a PCI Express host adapter.
• Fast sustained write: Up to 1100 MB/s write performance supports recording high-bitrate 4K RAW and long continuous bursts without buffer stalls.
• Cinematic storage: CFexpress Type B capacity handles large video files and high-resolution sequences, making it suitable for cinema-quality projects.
• Reliable frame delivery: Engineered to reduce dropped frames and corrupted files so playback and postproduction are more predictable.
• Rugged build: Shock- and vibration-resistant construction protects data integrity in demanding field shoots and action environments.
• Wide camera support: Compatible with professional bodies such as Panasonic S1 / S1R and Canon EOS R5 and EOS-1DX Mark III, plus Cinema line cameras.

Who It's For

The card is aimed at professional videographers, wedding and event shooters, and advanced photographers who record large volumes of high-resolution footage and need fast offload speeds to keep a tight turnaround. Users who work with 4K RAW or long continuous bursts will benefit from the sustained write performance and reduced buffer times.

Casual users with basic HD shooting needs or photographers who rarely capture long RAW sequences may find this level of performance more than required and could choose lower-cost cards instead. Also note that full speed requires a PCIe host adapter for the fastest transfers.

Pros & Cons

Pros

• Extremely fast read speeds up to 1700 MB/s speed up workflow and offload times.
• Sustained write performance of up to 1100 MB/s supports continuous 4K RAW recording without dropped frames.
• Rugged, shock-resistant design helps preserve data integrity in demanding shoots.
• Broad compatibility with pro cameras including Canon and Panasonic cinema and mirrorless models.

Cons

• Top transfer speeds require a PCI Express host adapter, so users without one will not see the absolute maximum throughput.
• High-performance cards can be more costly than standard memory cards, which may be unnecessary for light users.
