A CFexpress Type B card can fit the camera but still be the wrong media for a particular recording mode. Start with the camera’s approved-media table and required sustained-write class, not an “up to 3,700 MB/s” headline. Type B is physically different from the smaller Type A cards used by many Sony bodies, and a card’s CFexpress 4.0 reader speed does not prove what an older camera can write to it.
This seven-card selection spans 128 GB to 1 TB, CFexpress 2.0 and 4.0, and rated and unrated listings. Recording performance and speed were not independently tested for this guide. For paid work, confirm the part number against the camera’s current mode requirements and test before production.
Record the body, firmware, codec, frame rate, and data rate first. A VPG logo or large peak-read number is only useful when the camera mode accepts that exact media class.CFexpress Type B Cards Compared

1. Delkin BLACK 1TB — Best Confirmed VPG400 Option
Delkin’s BLACK 1TB listing names CFexpress 4.0 Type B and VPG400, with up to 3,700 MB/s read, 3,220 MB/s write, and a separate 2,040 MB/s sustained-write vendor claim. Delkin’s BLACK product page describes the same line, while the CFA certified-card list includes the 1 TB BLACK part number DCB4BV41T at VPG400. Confirm that part number on the actual offer or package before depending on its certification.
VPG400 is the certified 400 MB/s class, not the listing’s 2,040 MB/s vendor number or its 3,220 MB/s peak. A 1 TB card supports long takes and fewer swaps, but losing the card before offload puts more footage at risk. The seller’s shock and water language was not independently tested here. Use the body-specific media table, a verified second copy, and a card rotation plan rather than treating a premium card as a backup.
Our Take Choose BLACK for the strongest exact-model VPG evidence here. Its vendor speeds are secondary to the certified class and camera compatibility.
- 1 TB BLACK 4.0 appears on CFA VPG400 list.
- Large capacity for long takes.
- Delkin publishes a separate sustained-write claim.
- More footage on one physical card.
- Peak and vendor sustained speeds are not camera tests.
2. SANDISK Extreme PRO 128GB — Best Compact Dual-VPG Claim
The exact SDCFEB-128G-GN4NN is a 128 GB CFexpress 4.0 Type B card. Its checked listing says the 128 to 400 GB family supports both VPG400 and VPG800, whereas larger 1 to 4 TB variants claim VPG1600. The same split by capacity appears on SANDISK’s product family page. So a rating from a family page must be mapped back to the exact 128 GB SKU before buying.
Retailer data for the same model gives different peaks. Do not use a family-wide maximum as a guaranteed speed. Check whether the camera recognizes its VPG mode and whether the exact part appears on the CFA list when certification is required. This 128 GB card can fill quickly. Bring spare media.
Our Take Choose SANDISK as the compact dual-VPG-claim candidate. Capacity-specific rating and camera recognition count for more than its maximum read headline.
- Maker states VPG400 and VPG800 for 128 GB family.
- CFexpress 4.0 Type B.
- Small rotation capacity.
- 128 GB can fill quickly.
- Peak speeds vary by source and test path.
- Exact certificate should be checked.
3. ProGrade Gold 512GB — Best Mid-Capacity Vendor Speed Claim
ProGrade’s Gold offer is 512 GB CFexpress 4.0 Type B with a seller-stated 850 MB/s sustained write and up to 3,400 MB/s read. That capacity is useful when a 128 GB card would require constant swaps but a 1 TB card would hold too much unbacked footage. The vendor also describes serial tracking, a three-year warranty, and optional Refresh Pro software. Those items are support and management features, not a substitute for checking the camera’s approved-media list.
The checked offer does not state a VPG certification class for this exact Gold card. Do not convert its 850 MB/s vendor sustained figure into VPG800 or VPG400. A camera mode that explicitly requires a VPG-certified card may treat an unrated card differently even if a benchmark looks fast. The listing also uses broad language about backward compatibility with XQD. Confirm actual host firmware and accepted media before relying on that for an older camera.
Our Take Choose ProGrade Gold as a mid-capacity vendor-speed candidate if you will verify the intended body’s mode and exact card approval before a high-stakes shoot. It is not a demonstrated VPG choice.
- 512 GB capacity.
- 850 MB/s sustained-write vendor claim.
- Serial tracking and optional tool listed.
- No VPG class stated in checked offer.
- Vendor claim is not a camera-mode guarantee.
4. Delkin POWER 512GB — Best High-Speed Non-VPG Contrast
Delkin’s separate POWER 4.0 offer lists 512 GB, up to 3,650 MB/s read, up to 3,240 MB/s write, and 820 MB/s sustained write. It is a Type B card, but POWER is not BLACK. The checked listing does not claim VPG certification. A retailer’s model-specific answer also says DCFX4P512 is not VPG rated. Do not import the BLACK line’s VPG400 class just because both cards share the Delkin name and CFexpress 4.0 interface.
The included case and replacement policy do not establish high-bitrate compatibility. Test the planned mode for a full-length clip. If formal VPG is required, BLACK is better documented.
Our Take Choose POWER for high vendor-stated speeds if your camera mode does not require VPG. Strong vendor numbers do not make it the same certified product as Delkin BLACK.
- 512 GB and high vendor-stated peaks.
- Protective case listed.
- No VPG class for exact POWER offer.
5. Nextorage B3SE 256GB — Best Short Rotation Card
Nextorage’s NX-B3SE256G is a 256 GB CFexpress 4.0 Type B card. The checked offer lists up to 3,900 MB/s read and 2,000 MB/s write when paired with a compatible 4.0 reader, plus an included case and rescue-software download. Its model-specific support page can be used to check particular camera bodies rather than relying on a generic “Canon/Nikon” list. The smaller capacity suits a deliberate frequent offload cycle.
The listing uses “buffer-free” and “8K 60fps” language, but neither is a cross-camera promise. The checked bullets do not establish a formal VPG class for this exact card. A 400 MB/s phrase in the copy appears as a claim about shooting performance, not a VPG400 certification. Match the exact body and codec, and make verified copies before erasing a card. Recovery software is a fallback attempt, not the primary data-protection plan.
Our Take Choose B3SE as a 256 GB Type B 4.0 candidate for frequent rotation. Treat its reader peaks and recording language as seller claims until the camera workflow is checked.
- Exact 256 GB model has maker compatibility page.
- Case and rescue software listed.
- No VPG class established in checked offer.
- Reader peaks need a matching host path.
6. PERGEAR Master 512GB — Best Peak-Speed Claim to Scrutinize
PERGEAR’s Master Series is a 512 GB CFexpress 4.0 Type B card with seller-stated peaks of up to 3,500 MB/s read and 3,400 MB/s write. It names many Canon, Nikon, Panasonic, and other cameras in one compatibility paragraph. That breadth needs skepticism because camera bodies, firmware, and individual codecs differ, and some listed models may not even use a Type B slot. Check the maker’s exact camera support for your body rather than treating the list as a validation report.
The checked offer does not state a VPG certification class or a measured minimum sustained-write rate. “Drop-free 8K” is a marketing outcome, not a guarantee for a specific codec. It is a candidate for a mode that the camera accepts after testing, but it is not the conservative first choice when the body demands a VPG-listed card. Peak copy speeds to a laptop also require a suitable 4.0 reader and destination drive.
Our Take Choose PERGEAR if you want high seller-stated peak speeds and will verify the camera and recording path before putting paid footage on it. Its exact-mode evidence is thin.
- 512 GB Type B 4.0 identity clear.
- High peak figures stated.
- No VPG class stated.
- Broad camera and no-drop claims unverified.
7. Lexar SILVER 128GB — Best Older 2.0 Spare
Lexar’s older SILVER offer is a 128 GB CFexpress 2.0 Type B card with peaks up to 1,750 MB/s read and 1,300 MB/s write. It is a small spare in this lineup and can suit a camera whose own interface or selected recording mode does not require a faster or VPG-certified card. The listing’s “8K video” phrase is not a body-specific mode approval. Check the intended camera’s support table and perform a full-duration test before using it as an emergency spare on a paid shoot.
The seller says select XQD cameras, not all XQD cameras. No VPG class is stated, and 128 GB can fill fast at high bitrates.
Our Take Choose Lexar SILVER as a small CFexpress 2.0 spare if exact camera compatibility is established. Do not infer VPG or universal XQD support from its title.
- Small 128 GB rotation option.
- Type B 2.0 identity clear.
- No VPG class stated.
- Only select XQD compatibility claimed.
Buying Guide: Match Media Class to the Camera Mode
Confirm the slot and approved recording mode
CFexpress Type B will not fit a Type A slot. Some camera bodies also accept XQD in a slot that resembles Type B, but that does not mean every Type B card works in every XQD-era camera or firmware. Read the current camera manual and approved-media table for the exact body. Record the video format, resolution, frame rate, data rate, and whether the camera asks for a VPG class. A generic “8K compatible” listing is not an approved-mode table.
CFexpress 4.0 is a card/reader generation, not automatic in-camera speed. A 4.0 card may operate in an older compatible host at its host’s limit. For a critical camera mode, check the maker’s exact media list and test a full-length clip before production. The CompactFlash Association card-type overview explains physical classes. It does not certify one body/card combination. Our USB-C hub guide concerns computer host ports after shooting, not camera-slot fit.
Separate VPG certification from seller speed numbers
The CFA Video Performance Guarantee program tests classes of minimum sustained video recording speed. VPG400 means the 400 MB/s class. VPG800 means the 800 MB/s class. Delkin’s separate 2,040 MB/s sustained claim is a vendor specification, not the meaning of VPG400. POWER and BLACK are different Delkin lines. ProGrade Gold, PERGEAR, Nextorage B3SE, and Lexar SILVER do not acquire a VPG class merely by advertising high peaks.
Check the CFA certified-card list by exact part number, capacity, and class. A higher VPG generation is not automatically recognized by a camera mode that checks an older class flag. The CFA’s VPG Profile 5 paper makes this distinction. SANDISK states both VPG400 and VPG800 for its 128 GB family, but verify the exact package marking and camera support. If the body requires certification, choose documented certified media rather than relying on a seller’s “minimum write” phrase.
Plan capacity and verified offload
128 GB, 256 GB, 512 GB, and 1 TB cards change the rotation schedule more than they change the camera’s codec. Estimate recording minutes from the body-selected bitrate and usable capacity, then bring enough cards to avoid reusing media before two copies exist. A 1 TB card reduces swaps but exposes more unbacked footage if it is lost or damaged. A 128 GB card needs more disciplined swaps. Neither protects the content by itself.
For offload, a matching CFexpress 4.0 Type B reader, cable, host port, and destination disk are needed to approach high peak-read figures. The USB-C docking station guide covers a fixed laptop desk, but a dock cannot make a slow reader or SSD faster. Verify the transferred files and keep cards unformatted until the copies are confirmed. Recovery software and warranties are not substitutes for that routine.
Frequently Asked Questions
Is a 3,500 MB/s card automatically safe for 8K RAW?
No. Peak read or burst write is not the same as sustained recording under the camera’s actual mode. The body may require a VPG class or list supported cards and capacities. A seller’s “8K RAW” wording may refer to one camera, codec, or short test rather than every 8K setting.
Check the body-specific media table and exact model, then record a test long enough to expose heat and capacity limits. For paid work, keep a verified backup and spare approved card. Do not assume a faster-looking card can bypass a camera’s media-class check.
Can I substitute a Type A or XQD card in a Type B camera?
Type A is physically smaller and not interchangeable with Type B. An XQD card may fit a dual-purpose slot in certain cameras, but support depends on the body, firmware, and recording mode. Lexar’s checked SILVER listing says select XQD cameras, not universal compatibility.
Use the camera maker’s current support documentation rather than forcing a card or trusting a broad marketplace compatibility list. A removable-media choice is only correct when the physical slot, protocol, and mode requirement all match.
Does a VPG800 label guarantee every VPG400 mode?
Not necessarily. The camera may check a specific VPG class or certification flag, and the CFA notes that higher-class cards do not automatically satisfy every older-class host expectation. A product expressly carrying both classes, like SANDISK’s 128 GB family claim, still needs exact-model and camera verification.
Match the camera’s required class to the card’s exact listed or package markings and consult the CFA certified-card list. Test the selected mode in the body. The VPG800 label alone is not a universal backward-compatibility promise.
Bottom Line
Choose Delkin BLACK 1TB for the clearest exact-line VPG400 evidence here, or SANDISK Extreme PRO 128GB for a compact dual-class manufacturer claim that needs exact-model checking. The other cards can fit a verified camera workflow, but their peak speeds are not VPG certificates. Buy for the body and recording mode, then keep enough media for verified offload.
