Sabrent has bolstered its memory card range with the launch of its CFexpress Type B cards in two capacities – 512GB and 1TB – with promised maximum read speeds of 1700MB/s and write speeds of 1500MB/s.
News of the CFexpress Type B cards comes under two months after Sabrent launched one of the world’s first ever 512GB V90 SDXC UHS-II cards.
That card promised the V90 Video Speed Class, meaning it never writes slower than the required 90MB/s sustained speeds to attain the V90 label.

Crucial 400MB/s write speed
Sabrent claims that the sustained speeds of the new CFexpress Type B cards are 1600MB/s (read) and 400MB/s (write).
That 400MB/s write speed is crucial, especially for video shoots that require uninterrupted writing to a card, as anything slower could result in video clips with dropped frames, duplicate frames or even a failure to record.
The Compact Flash Association currently only verifies cards to sustain 400 MB/s in order for them to achieve VPG400 certification, however the new Sabrent CFexpress Type B cards haven’t yet been verified or certified for official VPG400 status.
The Sabrent cards have maximum read speeds of 1700MB/s and maximum write speeds of 1500MB/s
Flash management techniques
Sabrent claimed, ‘Don’t let slow media hold you back. From capturing once-in-a-lifetime events in your town to scenic landscapes in harsh environments across the globe, Sabrent’s CFexpress Type B Cards are designed for demanding professional use cases. Don’t let your memory card slow you down: high read and write speeds means more time shooting and less time transferring. Adopting various advanced flash management techniques – including LDPC and RAID error correction, end-to-end data protection, wear-levelling, defect management and over-provisioning – Sabrent’s CFexpress cards are built to endure years of use to keep your content safe.’
Sabrent hasn’t yet published a full list of compatible cameras but has said the cards have ‘broad’ camera compatibility for both consumer and professional models.
The Sabrent 1TB card costs $489.99 and can be pre-ordered on Amazon
Pricing & availability
Both capacities are now available to pre-order on Amazon and will be officially released on 19 May 2022.
