Test setup and what these numbers mean

The reference setup used our own CFexpress Type A-to-PCIe adapter, an MSI PRO Z690-A motherboard, Intel Core i9-12900K and Windows 11 Enterprise. These are PC transfer results, not camera recording speeds.

Sequential figures: CrystalDiskMark 8.0.2 x64, SEQ1M Q8T1, 1GiB test size, five passes. Full-card write figures: AIDA64 Linear Write, with the block size shown for each capacity.

Our supplier confirmed a matching controller, flash and firmware configuration. These are reference measurements, not our own PC tests of every shipped card. Host, reader, capacity, temperature and workload can affect results. A lowest observed value is not a guaranteed minimum or VPG certification.

03 / Your camera

Type A. Across generations.

For cameras and readers with a CFexpress Type A slot. Our Type A range includes PCIe 3.0 and PCIe 4.0 versions, used the same way. The card featured on this page is the PCIe 4.0 model.

Type A is not interchangeable with CFexpress Type B, CFast, CompactFlash or SD. Check that your camera’s slot is marked CFexpress Type A, not a generic “CF” label.

01 / PCIe 3.0

The PCIe 3.0 version

Our PCIe 3.0 Type A card, rated up to 800 MB/s read and write. Same card size, same use in Type A cameras and readers.

02 / PCIe 4.0

The PCIe 4.0 version

The featured card. It also works in Type A cameras and readers built for PCIe 3.0, at that host’s speed: in our PC reference test the 1TB card read at about 905 MB/s on PCIe 3.0, against about 1800 MB/s on PCIe 4.0.

The camera decides which recording modes a card can be used for. Check your camera manual for the card speed each format needs, and keep its firmware up to date. Our footage was recorded on a Sony FX3; other cameras and modes have not been tested by us. No VPG certification is claimed. A card reader is not included; for full offload speed, use a CFexpress 4.0 Type A reader on a fast enough port.

Product questions, camera matching and warranty support — a direct conversation with Lambda Grove.

Contact Lambda Grove
Which cameras take this card?

Cameras and readers with a CFexpress Type A slot, today mainly Sony Alpha and Cinema Line bodies. Our demonstrations use a Sony FX3. If you are unsure, send us your camera model and recording format and we will help you check.

Can I use this PCIe 4.0 card in an earlier Type A camera?

Yes, in compatible earlier-generation CFexpress Type A devices. A PCIe 3.0 host limits the card to the host’s supported speed. Available recording modes still depend on firmware and media requirements. Type A is not Type B, CFast or CompactFlash.

What does PCIe 4.0 mean on this card?

PCIe 4.0 x1 with NVMe is the card’s interface, and the card follows the CFexpress 4.0 standard. Our CFexpress Type A Memory Card - PCIe 3.0 belongs to CFexpress 2.0 and is rated up to 800 MB/s. Both fit cameras and readers with a CFexpress Type A slot, and a PCIe 3.0 host limits this card to the host’s speed.

Why are my transfer speeds lower than the benchmarks?

The benchmarks are peak results from a PC test setup. A slower reader, a USB port, a PCIe 3.0 host, a long sustained write or a different computer all change the figure. In-camera recording speed is set by the camera and its recording mode, not by the card’s peak.

What does the test video show?

You receive your order's test report and full packing video; a test video is supplied where available. The Sony FX3 clips shown here demonstrate the supplied sample and recording setup. The separate PC performance figures are reference benchmarks for a supplier-confirmed matching configuration.

What warranty is included?

This CFexpress Type A card has a five-year limited warranty from delivery for covered defects under normal use. CFexpress Type A and Type B cards both carry five years; other products have a 180-day limited warranty. Read the full warranty policy below or contact info@lambdagrove.com.

Can I return it if it does not suit my camera?

You can ask for a change-of-mind return within 14 calendar days after your order is delivered. Written approval and an RMA number are needed before you send anything back, and an approved return of a non-defective item has a 15% restocking fee where the law allows. A card that matches its description but does not suit your camera is not a warranty defect, so check your slot and recording format first, or ask us.

Can I buy several cards for my team?

Yes. For multi-card orders and business enquiries, contact b2b@lambdagrove.com.
