64GB UDMA CF Card 60MB/s - High-Speed CompactFlash for DSLR

In this review of the 64GB UDMA CompactFlash card from GYWY, the bottom line is simple: photographers who need reliable, high-capacity storage for burst shooting and long video records will appreciate its balance of speed and value. The card leverages UDMA 7 technology to offer a read speed up to 600x (60MB/s), making it a straightforward choice for DSLR users who shoot stills and 1080p or higher video. The review focuses on real-world use with Canon EOS DSLRs and HD camcorders and evaluates endurance, transfer responsiveness, and compatibility.

Key Features

• UDMA 7 Performance: Delivers read speeds up to 600x (60MB/s) to reduce buffer recovery times during continuous shooting and speed up file transfers.
• 64GB Capacity: Provides ample room for large RAW files and extended video recordings without frequent card swaps on location.
• DSLR Compatibility: Designed to work with Canon EOS Rebel and similar DSLR bodies, so photographers can take full advantage of camera burst and video modes.
• Video Ready: Supports capture of high quality images and 1080p full HD, 3D and 4K workflows in cameras that accept CompactFlash media.
• File Workflow: Faster read performance helps speed imports to a workstation for quicker editing and turnaround on projects.

Who It's For

The card is aimed at enthusiast and professional photographers using CompactFlash-compatible DSLRs and HD camcorders who need a reliable 64GB option for mixed stills and video work. It is a good fit for travel shooters, event photographers and hobbyists upgrading from slower cards who want faster transfer and buffer recovery.

Photographers who demand the absolute fastest write speeds for very high bitrate continuous 4K video or modern mirrorless cameras that use newer card formats should look at other media optimized for those specific systems. This card is best used where CompactFlash support and UDMA 7 performance align with the camera's capabilities.

Pros & Cons

Pros

• Solid UDMA 7 read performance speeds up transfers and reduces wait time between bursts.
• Generous 64GB capacity accommodates large RAW shoots and extended HD video sessions.
• Works with Canon EOS Rebel and many DSLR cameras that accept CompactFlash, making it versatile for legacy bodies.

Cons

• Read speed is capped at 60MB/s; users needing higher sustained write speeds for modern high-bitrate 4K may need a different card.

Our Verdict

The GYWY 64GB UDMA CompactFlash card is a pragmatic choice for photographers using CF-compatible DSLRs who want reliable capacity and improved transfer speed without a premium price.

For shooters who require the fastest sustained write rates for modern high-bitrate 4K or who use newer card formats, other options may be better, but for legacy DSLR users this card represents good value.

Frequently Asked Questions

Will this card work in my Canon EOS Rebel?
Yes, it is specified for Canon EOS Rebel DSLR compatibility and will function in cameras that accept CompactFlash media and support UDMA modes.

Can it record 4K video reliably?
The card supports 4K capture where the camera permits CompactFlash media, but sustained write speed is geared more toward 1080p and moderate bitrate 4K; very high bitrate 4K workflows may require faster media.

How much shooting time does 64GB provide?
Shooting time depends on file type and bitrate; 64GB is ample for many RAW sessions and hours of 1080p video, but exact duration varies by camera settings and file sizes.
