Sony 640GB CFexpress Type A Memory Card, 800MB/s Read & 700MB/s Write, High-Capacity for Video

The Sony CEA-G640T CFexpress Type A Memory Card delivers professional-grade performance in a compact TOUGH form factor, offering 640 GB of storage with sustained write speeds that meet VPG-400 requirements. Designed for demanding 4K/8K workflows and high-burst photography, it pairs PCIe Gen3 throughput with rugged, IP57-rated durability, minimizing workflow interruptions on location.

With maximum read speeds up to 800 MB/s and maximum write speeds up to 700 MB/s, the CEA-G640T reduces offload times and supports long continuous recording sessions. Its thermal-optimized construction and Sony media utilities add layers of reliability for pro shooters using Alpha and Cinema Line cameras.

Problem

Professionals face lost frames, thermal throttling, and long offload times when media cannot sustain high-bitrate recording or move files quickly. Smaller capacity cards force frequent swaps mid-shoot, increasing risk and slowing workflows.

• Dropped frames during high-bitrate 4K/8K recording.
• Extended downtime from slow read/offload speeds.
• Workflow disruption due to frequent media changes.

Solution

The Sony CEA-G640T solves these issues by combining VPG-400 sustained write guarantees with high peak throughput and a TOUGH chassis, enabling continuous, reliable recording and faster post-shoot transfers. Use it in compatible Sony Alpha and Cinema Line cameras to preserve capture integrity and speed delivery.

Benefits

• Reliable Recording: VPG-400 ensures no frame loss during long takes.
• Faster Workflow: 800 MB/s read speeds cut offload time significantly.
• Field-Ready: IP57 protection keeps media safe in harsh conditions.
• Operational Efficiency: Large 640 GB capacity reduces card swaps.

Applications

• Professional 4K/8K video production with Sony Alpha and Cinema Line cameras.
