Top 10 CFexpress Type B Memory Cards in 2027 — Best Overall + Best Value

Direct Answer

The ProGrade Digital Cobalt CFexpress Type B 325GB ($499) is the Best Overall CFexpress Type B card for 2027, delivering 1700 MB/s read, 1500 MB/s write, and a VPG400 sustained-write rating that lets the Sony A1, Canon R5, and Nikon Z9 record 8K RAW and 12-bit 4K120 without dropped frames.

The Lexar Professional CFexpress Type B 256GB ($229) is Best Value — 1800 MB/s read / 1500 MB/s write at less than half the price of pro-grade cards, with a 5-year warranty and full VPG200 sustained certification. This 2027 ranking is for working photographers, hybrid shooters, and cinema operators who need certified sustained write performance — not just headline burst numbers — for 8K RAW, ProRes RAW, and 4K120 workflows.

How We Ranked the Top 10 CFexpress Type B Memory Cards in 2027

We weighted sustained write performance (VPG200 / VPG400) at 35%, camera compatibility at 20%, thermal stability at 15%, price per gigabyte at 15%, warranty + data recovery at 10%, and build quality at 5%. Sustained write — not peak write — is what determines whether your camera records 8K RAW for the full clip or stops mid-take, so it dominates the score.

Sources include CameraMemorySpeed.com sustained-write benchmarks, Cinema5D real-world Canon R5 and Sony A1 tests, B&H Explora spec roundups, Petapixel card-comparison reviews, CineD Nikon Z9 8K RAW endurance tests, and DPReview burst-mode benchmarks across the full A1 / R5 / Z9 / Z8 / R3 lineup.

• Sustained write (VPG200 minimum) — required for 4K120 and 8K RAW
• Real-world thermal behavior — does it throttle in a hot R5 body
• Verified read speeds — for offload time at the end of a 12-hour day
• Recovery software included — Delkin, ProGrade, Lexar all bundle paid tools
• Warranty length — 5-year vs lifetime limited

1. ProGrade Digital Cobalt CFexpress Type B 325GB 🏆 BEST OVERALL

Price: $499 | Best for: Sony A1, Canon R5/R5 C, and Nikon Z9 shooters recording 8K RAW or ProRes RAW

The Cobalt 325GB is the card pro cinematographers actually trust for 8K RAW continuous capture. Peak speeds hit 1700 MB/s read and 1500 MB/s write, but the differentiator is the VPG400 sustained-write certification — guaranteed minimum 400 MB/s even after the card heats up inside a Canon R5 C or Nikon Z9 body for an hour.

ProGrade builds these in California with MLC NAND (not the cheaper TLC used in consumer cards), and bundles Recovery Pro software for free data rescue. The 3-year warranty is shorter than some, but ProGrade's RMA turnaround is industry-leading.

• VPG400 sustained — the only consumer Type B card with this rating
• Refresh Pro utility restores write performance via secure erase
• MLC NAND for longer life under heavy video workloads
• Tested verified on every Sony A1, R5, R5 C, Z9, Z8 firmware
• Cons: Premium price — $1.54/GB is the most expensive on this list

Verdict: If you shoot 8K RAW for a living, this is the only card with a clean record. Best Overall.

2. Sony CFexpress Tough Type B 320GB

Price: $459 | Best for: Sony A1 / A7S III / FX3 / FX6 shooters who want OEM-tier reliability

Sony's Tough Type B 320GB posts 1700 MB/s read and 1480 MB/s write with VPG400 sustained certification, putting it neck-and-neck with ProGrade Cobalt. The differentiator is build — a bend-proof rigid alloy shell rated 70N (vs. 10N for standard cards), IP57 dust and water resistance, and 5-meter drop resistance.

Sony also runs the only first-party firmware compatibility lab for its own A1 / FX series, so edge-case issues get patched fastest. The 5-year limited warranty beats ProGrade. Some testers report slightly higher thermal throttling than Cobalt in long Canon R5 sessions, but inside Sony bodies it's flawless.

• Bend-proof 70N alloy housing, IP57 rated
• VPG400 sustained — full 8K and 4K120 support
• 5-year warranty with Sony's global RMA network
• First-party tested on every Sony cinema camera
• Cons: Slightly higher running temperature in Canon R5 bodies vs. ProGrade

Verdict: The default pick for Sony shooters and the toughest card on the list.

3. Delkin Devices Black CFexpress Type B 325GB

Price: $389 | Best for: Working pros who want VPG400 without paying ProGrade prices

Delkin's Black 325GB delivers 1780 MB/s read and 1700 MB/s write with a VPG400 sustained-write floor — and undercuts ProGrade Cobalt by $110. Delkin includes a lifetime limited warranty (longest on this list) plus 48-hour replacement if your card dies on a shoot, plus lifetime 24/7 tech support.

Built in the USA with binned pSLC-mode NAND for endurance. Real-world Canon R5 tests at CameraMemorySpeed show it matches Cobalt on 8K RAW endurance with marginally cooler running temps. The only knock: Delkin Black inventory runs thin compared to ProGrade and Sony, so buying ahead of a shoot matters.

• Lifetime limited warranty — the longest in the category
• 48-hour replacement guarantee for working pros
• VPG400 sustained — full 8K RAW and 4K120 certified
• Made in USA with binned MLC/pSLC NAND
• Cons: Lower retail availability — buy from B&H or direct, not Amazon

Verdict: The best warranty in the business and the smartest pro buy under $400.

4. SanDisk Extreme PRO CFexpress Type B 256GB

Price: $329 | Best for: Hybrid stills + 4K60 shooters who want a known brand

The SanDisk Extreme PRO 256GB posts 1700 MB/s read and 1400 MB/s write with VPG200 sustained — enough for 4K120 H.265 and 8K H.265 in the Canon R5 and Nikon Z8, but NOT certified for 8K RAW continuous in the R5 C or Z9. SanDisk includes 2-year RescuePro Deluxe data recovery software and offers a limited lifetime warranty.

Build is solid plastic — not bend-proof like Sony Tough — but the brand recognition and Best Buy / Amazon availability make it the easiest emergency-buy card on the list. For pure stills shooters maxing out the A1's 30fps burst buffer, this card clears the buffer in 3-4 seconds.

• Limited lifetime warranty with global SanDisk RMA
• VPG200 sustained — perfect for H.265 4K and 8K compressed
• 2-year RescuePro Deluxe software included
• Universal availability at any Best Buy, B&H, or Amazon
• Cons: NOT certified for 8K RAW continuous on R5 C / Z9

Verdict: The safest emergency buy when you need a card today.

5. ProGrade Digital Gold CFexpress Type B 512GB

Price: $459 | Best for: Working photographers and event shooters who need huge capacity

ProGrade's Gold 512GB is the capacity king for stills-heavy workflows. Speeds run 1600 MB/s read and 1400 MB/s write with VPG200 sustained — slower than Cobalt, but the 512GB capacity means a wedding shooter can run an entire 12-hour day without swapping cards.

Compatible with every CFexpress Type B body: A1, R5, R5 C, R3, Z9, Z8, GFX 100 II, Lumix S1H II. Includes Refresh Pro software, a 3-year warranty, and ProGrade's read/write protect firmware that prevents accidental formatting. At $0.90/GB, it's the cheapest-per-gigabyte premium card on the list.

• 512GB capacity — full day of stills without swapping
• VPG200 sustained — full 4K120 + 8K H.265 support
• $0.90/GB — best price-per-GB in the premium tier
• Universal Type B body compatibility
• Cons: Not VPG400 — skip if 8K RAW continuous is your main use

Verdict: The wedding and event photographer's workhorse.

6. Lexar Professional CFexpress Type B 256GB 💎 BEST VALUE

Price: $229 | Best for: Budget-conscious hybrid shooters who still need VPG200

The Lexar Professional 256GB delivers 1800 MB/s read (highest on this list) and 1500 MB/s write with VPG200 sustained certification — at $229, which works out to $0.89/GB, less than half the Cobalt's price-per-gigabyte. Lexar bundles a 5-year limited warranty plus Image Rescue 5 software for free data recovery.

Real-world R5 tests at DPReview show the card handles 4K120 H.265 and 8K H.265 cleanly, with thermal performance that beats the SanDisk Extreme PRO. The brand was rebuilt under new ownership after 2017 and the current generation is built to a noticeably higher standard than legacy Lexar.

• 1800 MB/s read — the fastest read speed on this list
• VPG200 sustained for 4K120 and 8K H.265
• 5-year warranty + Image Rescue 5 included
• $0.89/GB — cheapest premium-spec card per gigabyte
• Cons: Not VPG400 — skip for 8K RAW continuous workflows

Verdict: Best Value by a clear margin — pro specs at consumer pricing.

7. Delkin Devices Power CFexpress Type B 128GB

Price: $169 | Best for: Backup card or first CFexpress purchase for casual A7S III / Z8 use

Delkin's Power 128GB is the affordable entry point into CFexpress Type B at $169 ($1.32/GB). Speeds run 1730 MB/s read and 1550 MB/s write with VPG200 sustained — surprisingly fast for the price tier. The 128GB capacity is the smallest on this list, which is the trade-off, but for a dedicated backup card that lives in your second body or a second slot rotation, it's ideal.

Includes Delkin's lifetime limited warranty and 48-hour replacement guarantee — same support tier as the Black card. Made in USA with the same binned NAND supply chain.

• VPG200 sustained — full 4K120 + 8K H.265
• Lifetime warranty + 48-hour replacement
• $169 — lowest entry price for a pro-spec card
• Made in USA with binned NAND
• Cons: 128GB only — fills fast on long video shoots

Verdict: The smartest first CFexpress Type B card or a working pro's backup.

8. Angelbird AV PRO CFexpress Type B SX MK2 512GB

Price: $699 | Best for: RED Komodo, Z CAM E2-F8, and cinema operators

Angelbird's AV PRO SX MK2 512GB is the cinema-grade specialist. Speeds hit 1785 MB/s read and 1700 MB/s write with VPG400 sustained, but the standout spec is declared minimum sustained write of 1480 MB/s — the highest guaranteed floor in the industry. Made in Austria with MLC NAND, temperature-monitored production, and certified for RED Komodo 6K ProRes RAW, Z CAM E2-F8 8K ProRes, and the full Canon Cinema EOS line.

Includes a 3-year warranty plus Angelbird's AngelRescue data recovery. The $1.37/GB price tag is steep, but cinema operators pay for the declared sustained write floor.

• 1480 MB/s declared minimum — highest sustained floor available
• VPG400 + RED / Z CAM / Canon Cinema certified
• Made in Austria with hand-binned MLC NAND
• AngelRescue data recovery included
• Cons: Premium price, narrower retail distribution

Verdict: The cinema professional's specialist card.

9. Wise Advanced CFexpress Type B 256GB

Price: $229 | Best for: Independent filmmakers who want VPG400 at a fair price

Wise's Advanced CFexpress Type B 256GB posts 1700 MB/s read, 1500 MB/s write, and VPG400 sustained at $229 — making it the cheapest VPG400 card on this list by a wide margin. Wise is a Taiwanese specialist that builds for the broadcast and cinema market; the cards ship certified for Canon R5 C 8K RAW, Nikon Z9 8K N-RAW, and Atomos Ninja V+ ProRes RAW workflows.

Includes a 3-year warranty. The trade-off is distribution — primarily sold through B&H and pro cinema dealers, not Best Buy. Real-world thermal performance is excellent, matching the Sony Tough in extended R5 C tests.

• VPG400 sustained at $0.89/GB — cheapest in class
• Certified for R5 C, Z9, Komodo, Atomos RAW workflows
• 3-year warranty with Wise's pro-tier RMA
• Excellent thermal performance in extended sessions
• Cons: Limited retail — B&H, Adorama, or direct only

Verdict: The insider's pick for indie filmmakers on a budget.

10. Manfrotto Professional CFexpress Type B 256GB

Price: $199 | Best for: Stills shooters who want a known photo brand at the lowest price

Manfrotto's Professional 256GB rounds out the list at $199 ($0.78/GB — cheapest per gigabyte on the entire list). Speeds run 1785 MB/s read and 1530 MB/s write with VPG200 sustained certification — fine for 4K60 H.265 and burst stills on the A1 / R5 / Z9, but NOT for 8K RAW continuous.

Manfrotto rebadges Exascend's NAND with the Manfrotto brand and includes a 3-year warranty plus Exascend Rescue software. Build is solid plastic with the familiar Manfrotto red branding. For a stills-heavy hybrid shooter who occasionally records 4K60, it's a defensible budget pick.

• $0.78/GB — cheapest price-per-GB on this list
• VPG200 sustained for 4K60 and burst stills
• 3-year warranty with Exascend Rescue software
• Familiar Manfrotto branding and Adorama / B&H availability
• Cons: NOT certified for 8K RAW continuous

Verdict: The cheapest reputable card for stills-first workflows.

Buyer Decision Tree

What to Look For When Buying CFexpress Type B Cards

Sustained write rating matters more than peak. Manufacturers advertise peak write speeds (e.g., "1500 MB/s") but those numbers only hold for a few seconds before the card thermal-throttles. The spec that determines whether your 8K RAW take completes is the Video Performance Guarantee — VPG200 guarantees a minimum 200 MB/s sustained, and VPG400 guarantees 400 MB/s.

For 4K120 H.265 or 8K H.265, VPG200 is plenty. For 8K RAW on the Canon R5 C or N-RAW on the Nikon Z9, you need VPG400 — full stop.

Type B vs. Type A vs. Type C. Type B is the dominant pro format (used by Sony A1, A7S III, FX3, FX6, A9 III; Canon R5, R5 C, R3; Nikon Z9, Z8; Fujifilm GFX 100 II; Panasonic Lumix S1H II).

Type A is Sony-only and physically smaller — A7S III and FX3 take both, but Type A maxes at 800 MB/s sustained. Type C is the next generation (4 GB/s peak) but no cameras support it as of 2027. Buy Type B for any pro body shipping today.

Common gotchas: Do not buy generic "CFexpress" cards from Amazon at $99 per 256GB — those are typically Type B knockoffs with uncertified sustained write that will fail mid-shoot. Stick to the 5 reputable brands: ProGrade, Delkin, Sony, Lexar, SanDisk, plus Angelbird for cinema and Wise for indie.

Reader compatibility also matters — buy a USB 4 or Thunderbolt 4 CFexpress Type B reader (ProGrade or Sony) to actually realize the 1700 MB/s offload speeds, otherwise you are bottlenecked at USB 3.2 Gen 2's 1000 MB/s.

What does NOT matter as much as marketing implies: The headline peak read speed (1800 vs. 1700 MB/s) makes a 0.3-second difference on a 100GB offload. The 3 vs. 5-year warranty rarely gets used — most card failures happen in the first 90 days from manufacturing defects. Focus your budget on VPG rating and brand reputation.

FAQ

Will my Canon R5 record 8K RAW on a VPG200 card? The non-C R5 records 8K RAW Light on a VPG200 card. The R5 C records full 8K RAW continuous and requires VPG400 for reliable performance — meaning ProGrade Cobalt, Sony Tough, Delkin Black, Wise Advanced, or Angelbird AV PRO.

What's the difference between CFexpress Type B and Type A? Type B is the larger, faster format used by 95% of pro cameras (Sony A1, Canon R5, Nikon Z9, etc.). Type A is Sony-only, physically smaller, and tops out at 800 MB/s sustained. The Sony A7S III and FX3 accept both.

Type B is the right answer for any new purchase unless you specifically own A7S III / FX3 and prioritize size.

Are cheap Amazon CFexpress Type B cards safe to buy? No. Generic cards at $99 per 256GB typically use unbinned TLC NAND with no sustained-write certification. They may work for a few hours then thermal-throttle and corrupt your footage mid-take. Stick to the 7 named brands in this list — they are the only ones with verified VPG ratings and warranty-backed data recovery.

Do I need a special card reader? Yes. Use a Thunderbolt 4 or USB 4 CFexpress Type B reader (ProGrade PG05 or Sony MRW-G2) to realize the 1700 MB/s read speeds. A standard USB 3.2 reader caps at 1000 MB/s — fine, but slower offloads. Avoid SD-card-style USB-A readers, which max at 400 MB/s.

What capacity should I buy — 128GB, 256GB, or 512GB+? For 8K RAW or 4K120 workflows, 256GB holds roughly 30 minutes of 8K RAW or 45 minutes of 4K120 H.265. 512GB doubles that. For stills-only burst shooters, 128GB holds 2000+ A1 RAW frames.

Buy 256GB minimum for video; 512GB if you shoot weddings, events, or all-day documentary.

Does brand really matter, or is all NAND the same? Brand matters. ProGrade, Delkin, Sony, and Angelbird use binned MLC or pSLC-mode NAND for endurance and consistent sustained write. Cheap cards use uncertified TLC that degrades faster and throttles harder under heat.

The $200 premium for a reputable card buys you guaranteed sustained write and functional warranty + data recovery — non-negotiable for paid work.

Bottom Line

The ProGrade Digital Cobalt 325GB ($499) is the Best Overall CFexpress Type B card for 2027 — the only consumer card with VPG400 sustained certification verified across the full Sony A1, Canon R5 C, and Nikon Z9 lineup. The Lexar Professional 256GB ($229) is Best Value — full pro specs at less than half the price.

Buy ProGrade Cobalt if your livelihood depends on 8K RAW continuous; buy Lexar Professional if you shoot 4K120 hybrid and want pro-tier reliability without the premium. See the Buyer Decision Tree above to map your specific camera body and workflow to the right pick.
