Overview

The Sony CEA-G80T is an 80GB CFexpress Type A memory card built for photographers and videographers who need sustained, high-speed data capture. Leveraging a PCI Express Gen3 x1 interface, the card achieves maximum read speeds of 800MB/s and write speeds of 700MB/s — fast enough to keep pace with high-bitrate 4K120p and 8K recording modes found in cameras like the Sony A1 and A7S III. That throughput also translates to faster offloading when transferring footage to a workstation via a compatible CFexpress reader.

Measuring just 20.0 × 28.0 × 2.8 mm and weighing approximately 3 grams, the CEA-G80T is one of the smallest high-performance storage options available for professional cameras. Sony's engineering focuses on physical resilience as well, with the card rated to handle shocks, static, and wide temperature swings common in field production. The 80GB capacity positions this card as a fast-swap option for critical shots or shorter recording sessions rather than a bulk-storage solution, making it a smart complement to larger-capacity cards in a professional media kit.

Frequently Asked Questions

The CEA-G80T works with cameras and devices that support the CFexpress Type A standard, including select Sony Alpha mirrorless cameras such as the A7S III, A1, and FX6.
At 800MB/s read and 700MB/s write, this card is significantly faster than even the quickest UHS-II SD cards, which typically max out around 300MB/s. This makes it well-suited for high-bitrate 4K and 8K video recording.
Yes. Sony engineers this card to withstand drops, vibration, and extreme temperatures, making it reliable for demanding field conditions.
No. CFexpress Type A and Type B are physically different sizes and are not cross-compatible. You need a device with a CFexpress Type A slot or a compatible adapter.
It depends on your recording format and bitrate. For high-bitrate 4K recording, 80GB fills up relatively quickly, so it works best as a complement to larger cards or for shorter shoots where fast write speeds are critical.
