Quick comparison of the picks

All figures are manufacturer maximums from ProGrade’s shop pages. Real transfers depend on the host device, cable and reader, and ProGrade’s published figures for some SD cards differ slightly between its announcement and product pages.

Why ProGrade, and what you actually pay for

ProGrade Digital was founded by veterans of the professional card market and focuses on cards for working photographers and videographers rather than casual phone storage. Its cards carry sustained-performance specifications rather than only headline burst speeds, and SD cards support Refresh Pro, a utility that reports card health and restores write performance. Many cards are X-ray and shock proof and come with a limited warranty (three years on some CFexpress models, longer on others), but warranty terms differ by product, so confirm them on the product page for the exact card.

The value is consistency. Burst numbers look impressive on a box, but a long video clip or a long burst of raw files depends on the minimum sustained write speed. A card advertised at 3,000 MB/s burst may drop to 850 MB/s sustained, which is still plenty for most formats but important when you plan for a codec that demands a guaranteed rate.

Best top-tier CFexpress: CFexpress 4.0 Type B Iridium

The Iridium line is ProGrade’s top series, with rated reads up to 3,550 MB/s and writes up to 3,000 MB/s in capacities of 400GB, 800GB and 1.6TB. It uses PCIe Gen 4 x2 NVMe and is backwards compatible with CFexpress 2.0 hosts, though it runs at the slower host speed in those cameras.

Who it suits: shooters of 8K raw video or high-frame-rate raw stills on flagship mirrorless bodies that officially support CFexpress 4.0.

Trade-off: the speed advantage only appears in cameras that can use it. If your body is limited to CFexpress 2.0 speeds, you pay more for performance you cannot use. Fast cards also run warm, and ProGrade builds in thermal throttling to protect the card.

Best overall CFexpress Type B: CFexpress 4.0 Type B Gold

The Gold CFexpress 4.0 Type B card reads at up to 3,400 MB/s and writes at up to 3,000 MB/s burst. In the 256GB size, ProGrade quotes 850 MB/s minimum sustained write, while the 1TB and 2TB shop listings quote about 1,500 MB/s sustained. The cards use TLC memory in a metal enclosure, Gen 4 x2 NVMe, and thermal throttling. Smaller 240GB models have also been sold with lower burst figures (1,600 MB/s write), so read the rating for the capacity you are buying.

Who it suits: wedding, wildlife and sports photographers using Canon, Nikon or Panasonic bodies with Type B slots, as well as video shooters recording raw or high-bitrate intra-frame formats.

Trade-off: sustained write varies by capacity, so the larger cards are the better choice for long clips. Many photographers also keep the 2.0 generation card as a backup because it costs less.

Best value Type B: CFexpress 2.0 Type B Gold

The 2.0 Gold Type B card reads up to 1,700 MB/s and writes up to 1,500 MB/s in capacities from 128GB to 1TB. It is the right match for cameras released in the first wave of CFexpress, which cannot use 4.0 speeds anyway.

Who it suits: owners of older Canon EOS R5, R3 and R6 bodies, Nikon Z6 II and Z7 II, and similar cameras who want reliable speed at a lower tier.

Trade-off: it is a previous-generation card and may eventually be discontinued. Check your camera’s manual for recommended cards before buying.

Best for Sony Type A slots: CFexpress 4.0 Type A Iridium

CFexpress Type A is the smaller format used in a number of Sony Alpha cameras and some Panasonic and Nikon models. The Iridium 4.0 Type A card reads at up to 1,800 MB/s and writes at up to 1,700 MB/s, in 480GB and 960GB capacities.

Who it suits: owners of Sony bodies with CFexpress A or dual SD and CFexpress A slots that record high-bitrate 4K at 120 frames per second or 10-bit all-intra video.

Trade-off: Type A cards have lower capacities than Type B, and many slots are hybrid, which means they also accept SD cards. If you only shoot stills, an SD V90 card often performs well enough for much less.

Budget Type A: CFexpress 2.0 Type A Gold

This card is rated for up to 900 MB/s reads and 800 MB/s writes in 240GB and 480GB sizes. It is a sensible way to use a Type A slot without paying for the 4.0 generation.

Who it suits: hybrid shooters who use all-intra 4K and want a faster buffer clear than SD can offer.

Trade-off: the 240GB card fills quickly at high bitrates, and the speed gap to the Iridium is large if your camera supports it.

Best SD card: SDXC UHS-II V90

ProGrade’s V90 SD cards offer reads up to 300 MB/s and writes up to 250 MB/s on the 300R Gold series, with the Iridium variant quoted at up to 275 MB/s writes and capacities up to 1TB. V90 means a guaranteed sustained write of at least 90 MB/s, enough for 4K video up to 400 Mbps and for long bursts of raw stills. The cards support Refresh Pro.

Who it suits: mirrorless and DSLR owners with UHS-II slots, drone pilots, and anyone who wants one card type across multiple cameras.

Trade-off: UHS-II cards need a UHS-II host to reach full speed. In a UHS-I slot they drop to roughly 90-100 MB/s.

Best value SD card: SDXC UHS-II V60 Gold

The V60 Gold card reads up to 250 MB/s with a 60 MB/s guaranteed sustained minimum, enough for 4K at 60p in most cameras. Burst write speeds are quoted between 100 and 130 MB/s depending on the source page, so check the sticker on the card itself. Capacities run from 128GB to 512GB.

Who it suits: general hybrid shooters, travel photographers and second-slot backups.

Trade-off: it will not keep up with the highest bitrate codecs, and long raw bursts clear the buffer more slowly than with a V90 card.

Readers and microSD

ProGrade also sells UHS-II microSDXC cards with V60 ratings (up to 250 MB/s read, 130 MB/s write), useful for action cameras, drones and handheld game devices. For offloading, the company’s dual-slot USB 3.2 Gen 2 reader accepts a CFexpress Type B and a UHS-II SD card and reaches up to 1.25 GB/s. In April 2026 the company announced USB 4 readers for CFexpress and SD with up to 40 Gbps. A fast reader matters because the card’s speed is wasted if you offload through a slow camera cable.

How to choose: a decision matrix

The numbers that matter

Recording time

Recording time equals capacity divided by bit rate. A 256GB card (about 256,000 MB) at a 1,000 Mbps video bit rate (125 MB/s) lasts about 2,048 seconds, or roughly 34 minutes. A 1TB card at the same rate lasts about 2.2 hours. At 400 Mbps (50 MB/s), a 128GB V90 card records for about 43 minutes. Always plan for the card to hold less than the label says, since formatting overhead takes a small share.

Burst depth

A raw still averages 45-60 MB at 45 megapixels. A camera shooting 20 frames per second produces about 900 MB/s to 1.2 GB/s, which exceeds what an SD card can sustain. That is why high-speed bodies need CFexpress: the card is what keeps the buffer from filling.

Offload time

Copying 512 GB through a reader at 800 MB/s takes about 11 minutes, while the same data through a 100 MB/s reader takes more than 85 minutes. A good reader saves hours over a season of shoots.

Durability and ownership realities

• Heat: CFexpress cards run hot during 8K video. Remove the card carefully after long recordings.
• Format in camera: always format in the camera that will use the card, not on a computer.
• Retire cards on schedule: flash cells wear. Many professionals replace heavily used cards every few years, and always before an important assignment.
• Do not delete in camera to recover space mid-shoot: swap cards instead, and keep two copies of important images before reformatting.
• Counterfeit risk: buy from authorized dealers. Fake cards are common for popular brands.

Using Refresh Pro and card health tools

1. Install the utility from ProGrade on your computer and attach the card through a reader.
2. Check health status to see wear indicators.
3. Run the refresh function after a card has been heavily used, since it can restore write performance by reorganizing memory.
4. Back up first. Always copy the files off before running any maintenance on a card.

If a card fails or files go missing

Stop shooting with the card and do not format it. Remove it, put it in a safe place, and use recovery software only on a copy of the card image if you can make one. For physically damaged cards, consult a professional data recovery service. This is general information, not professional advice for a specific case, and success cannot be guaranteed.

Pairing cards with real shooting scenarios

Weddings and events

Event photographers shoot continuously for eight to ten hours and cannot repeat the moment. Use dual slots in backup mode, with a CFexpress or V90 SD card in each, and swap at natural breaks such as the ceremony and reception rather than waiting for a card to fill. A 256GB card holds roughly 4,000 raw files from a 24-megapixel body, which comfortably covers most weddings, while a 45-megapixel body will fill the same card with closer to 2,500 files.

Wildlife and sports

Long, fast bursts are the hardest test for a card. Here the buffer clearing speed matters more than capacity. CFexpress Type B Gold or Type A cards let you keep shooting while the buffer empties, and a fast reader gets you through the post-event offload quickly. SD V90 cards are acceptable for cameras that top out at 10-15 frames per second.

Video and hybrid work

Match the card to the codec’s bit rate. Long-GOP 4K at 100-150 Mbps fits comfortably on V60, while all-intra 10-bit 4K at 600-800 Mbps and internal raw formats need V90 SD or CFexpress. Check the camera manual’s list of required card classes for each recording mode, because many cameras disable high-bitrate modes when a slow card is detected.

Drones and action cameras

Small devices tolerate heat and vibration poorly. Pick a microSD card with a guaranteed sustained write speed and format it in the device. Keep a spare card in the bag, because swapping a card is faster than debugging a corrupted one in the field.

Warranty and support considerations

Before buying, compare warranty length and what it covers. ProGrade lists three years on some CFexpress cards and limited lifetime coverage on others, which is a reminder to read the product page rather than assume. Keep your proof of purchase from an authorized retailer, register the card if the maker offers it, and note the serial number. If a card begins to show errors, stop using it for important work immediately and contact the maker rather than waiting for a complete failure.

A practical card kit for one photographer

A balanced kit for a hybrid shooter with a Type B body might be two 512GB CFexpress 4.0 Gold cards for primary shooting, one 256GB CFexpress 2.0 card as an emergency spare, and a 128GB V60 SD card for a secondary slot or a second camera. Number the cards, record which one holds which shoot, and keep them in a hard case with a desiccant packet. Rotate cards evenly so no single card absorbs all the wear. After each job, copy the files to two destinations, verify the copies open, and only then reformat the card in the camera. This routine costs a few minutes and removes nearly every common way to lose a shoot, including the mistake of reformatting a card that still holds the only copy.

Frequently Asked Questions

Is CFexpress Type B compatible with XQD cameras?

Some cameras that shipped with XQD slots, such as the Nikon Z6 and Z7, received firmware updates to accept CFexpress Type B. Always check the camera maker’s compatibility list before buying, because not every XQD body was updated.

Does a V90 card record faster than a V60 card?

V90 guarantees at least 90 MB/s sustained writes, while V60 guarantees 60 MB/s. For video, that determines the maximum bit rate. For stills, V90 cards also clear the camera buffer more quickly.

Can I use a CFexpress 4.0 card in a CFexpress 2.0 camera?

Yes. The 4.0 cards are backward compatible, but they run at the speed of the host. You gain nothing in speed unless the camera supports 4.0.

How big a card should I buy?

Choose a size that covers a full shooting day with a safety margin. Many photographers prefer several mid-sized cards over one huge card, so a single failure does not cost a whole event.

Are ProGrade cards worth the premium over mainstream brands?

If you depend on guaranteed sustained write speeds, long recording times or fast buffer clearing, yes. For casual stills, a cheaper UHS-I or V30 card is often enough.

What reader should I use?

Use a reader that matches your card: a USB 3.2 Gen 2 or faster dual-slot unit for CFexpress and UHS-II SD. Plugging directly into a camera over USB often runs slower than a dedicated reader.
