Pergear 512GB CFexpress 4.0 Type A Memory Card (2-Pack) - Fast 8K

In this review the Pergear 512GB CFexpress 4.0 Type A memory card 2-pack is assessed for professional creators who need reliable, high-speed storage. The bottom line: these cards are aimed at filmmakers and photographers who shoot high-bitrate 8K video or long RAW burst sequences and need much faster offloads; the single biggest reason to buy is the combination of up to 1780MB/s read and 1600MB/s write speeds in a dual 512GB kit that stays backward compatible with Type A slots.

Key Features

• High read speeds: Up to 1780MB/s read speed lets large 8K and RAW files transfer to a host quickly for faster postproduction.
• Fast write performance: Up to 1600MB/s write speed supports sustained high-bitrate 8K recording and rapid RAW burst capture without dropped frames.
• CFexpress 4.0 Type A compliance: Fully compliant with CFexpress Type A 4.0 and meets Type A 2.0 standards for broader device compatibility.
• 512GB capacity per card: Large 512GB cards reduce the need to swap media during long shoots and are sold here as a convenient two-pack.
• USB4.0 interface support: The next-generation USB4.0 interface is supported for maximum throughput when used with a compatible reader.
• Compatible with Sony Alpha and FX series: Designed to work with many Sony models such as ILME-FX3, ILME-FX6, ILME-FX30 and several A7 and A1 bodies.

Who It's For

These Pergear CFexpress 4.0 Type A cards are best for professional filmmakers and advanced hybrid shooters who record high-bitrate 8K video or require fast sustained write speeds for long RAW burst sequences. The 512GB size and two-card pack suit location shoots where swapping and downtimes must be minimized.

Casual photographers or users on tight budgets who rarely shoot beyond 4K or seldom record long RAW bursts should consider lower-cost cards or smaller capacities, and note that a CFexpress 4.0 Type A card reader is required separately to achieve the top USB4.0 transfer rates.

Pros & Cons

Pros

• Extremely fast read speed up to 1780MB/s for rapid offloads.
• Sustained write up to 1600MB/s supports high-bitrate 8K and long RAW bursts.
• Large 512GB capacity per card reduces media changes during shoots.
• Sold as a two-pack, which offers immediate redundancy or extended storage on set.

Cons

• Requires a CFexpress 4.0 Type A card reader sold separately to reach advertised USB4.0 speeds.
• High performance may be unnecessary for casual users who do not shoot 4K/8K or RAW bursts.

Frequently Asked Questions

Do I need a special card reader?

Yes. The cards are listed as compatible with multiple Sony models including ILME-FX3, ILME-FX6, ILME-FX30 and many A7 series bodies.

Is the two-pack useful for redundancy?
