Best UHS-I value
SanDisk Extreme Pro SDXC UHS-I 128GB
The UHS-I benchmark: 200 MB/s reads and V30 reliability for everyday shooting.
The Extreme Pro UHS-I is the default card for most cameras on earth for good reason: honest V30 video performance, fast reads for offload, bombproof availability and a price that lets you own several. If your camera is UHS-I only, stop shopping and buy two of these from an authorised seller.
Strengths
- Up to 200 MB/s read and 90 MB/s write with SanDisk QuickFlow on compatible readers
- V30 and U3 rated for uninterrupted 4K UHD video
- Shock, temperature, water and X-ray proofing
- The most widely stocked card here, so buy only from authorised sellers to avoid counterfeits
Limitations
- UHS-I bus caps sustained writes well below UHS-II V90 cards
- 200 MB/s reads need a QuickFlow-compatible reader; standard UHS-I readers are slower
- Counterfeits are common in marketplace listings, so seller choice is critical
| Format / bus | SDXC, UHS-I |
|---|---|
| Speed class | V30, U3, Class 10 |
| Max read / write | Up to 200 MB/s read, 90 MB/s write (128GB) |
| Capacities | 64GB to 1TB |
| Durability | Shock, water, temperature and X-ray proof |
Best for: Stills shooters and 4K V30 video on UHS-I cameras who want proven reliability cheaply.
Skip if: Your camera has UHS-II slots and you shoot long RAW bursts; you are leaving speed unused.
Best UHS-II for offload speed
Lexar Professional 2000x SDXC UHS-II
UHS-II speed up to 300 MB/s reads for fast offloads and cleared buffers.
The 2000x earns its place on read speed: 300 MB/s-class offloads change how a shoot day ends. Verify the video class on your chosen capacity, and hybrid shooters who prioritise turnaround over absolute sustained guarantees get superb value here.
Strengths
- Up to 300 MB/s reads dramatically shorten card-to-SSD offload times
- UHS-II second row of pins unlocks fast buffer clearing on compatible bodies
- Backward compatible with UHS-I slots at reduced speed
- Strong price-to-speed position among UHS-II cards
Limitations
- Video speed class varies by capacity, so verify V60 versus V90 on the exact SKU
- Peak write figures are burst numbers, not sustained guarantees
- Needs a UHS-II reader to realise the read speeds
| Format / bus | SDXC, UHS-II |
|---|---|
| Speed class | U3, V60 or V90 depending on capacity, check SKU |
| Max read / write | Up to 300 MB/s read, up to 260 MB/s write (select capacities) |
| Capacities | 64GB to 256GB |
| Durability | Temperature, shock and vibration resistant |
Best for: Hybrid shooters on UHS-II bodies who offload large shoots and hate waiting.
Skip if: Your video needs guaranteed V90 sustained writes; check the exact capacity's class.
Best SD for professional video
ProGrade Digital SDXC UHS-II V90 Cobalt
A true V90 card with 300 MB/s reads built for professional video and bursts.
When the codec demands a guaranteed 90 MB/s floor, ProGrade's V90 Cobalt is the SD card professionals reach for: true V90 sustained writes, 300 MB/s reads and health monitoring through Refresh Pro. It is the SD ceiling before CFexpress takes over.
Strengths
- Guaranteed V90 minimum sustained write of 90 MB/s for demanding codecs
- Up to 300 MB/s read and 250 MB/s write peak performance
- Refresh Pro health-monitoring support extends card life management
- Laser-etched serials and rigorous batch testing target pro reliability
Limitations
- Premium pricing per gigabyte versus V60 alternatives
- Full benefit requires UHS-II slots and reader throughout the workflow
- Smaller retail footprint than SanDisk and Lexar
| Format / bus | SDXC, UHS-II |
|---|---|
| Speed class | V90, U3, Class 10 |
| Max read / write | Up to 300 MB/s read, 250 MB/s write |
| Capacities | 64GB to 512GB |
| Extras | Refresh Pro compatible, custom laser-etched serial |
Best for: Professionals shooting high-bitrate video and long RAW bursts on UHS-II bodies.
Skip if: You shoot JPEG stills casually; V30 UHS-I cards deliver the same day for less.
Best CFexpress for durability
Sony TOUGH CFexpress Type B
The bend-proof CFexpress card with 1,900 MB/s reads for flagship bodies.
The TOUGH card's monocoque shell survives bending, drops and grit that retire ordinary cards, while delivering flagship-class read and sustained write performance. Field, wildlife and sports shooters who treat cards roughly should pay the Sony premium happily.
Strengths
- TOUGH monocoque construction resists bending, drops and dust far beyond standard cards
- Up to 1,900 MB/s read and 1,500 MB/s class write performance
- Sustained performance suited to 8K and high-framerate RAW video
- Media Scan Utility health monitoring via Sony readers
Limitations
- Premium pricing, especially at high capacities
- Type B only, so many Sony bodies need Type A instead
- Peak speeds need a fast CFexpress reader and USB or Thunderbolt bandwidth
| Format | CFexpress Type B |
|---|---|
| Max read / write | Up to 1,900 MB/s read, 1,500 MB/s write class |
| Capacities | 240GB to 960GB depending on series |
| Durability | TOUGH spec: bend, drop, dust and splash resistant |
| Monitoring | Sony Media Scan Utility compatible |
Best for: Flagship Sony, Nikon and Canon shooters who abuse cards in harsh field conditions.
Skip if: Your camera uses CFexpress Type A or XQD-only slots; check body compatibility carefully.
Best CFexpress for capacity
Lexar Professional CFexpress Type B Gold
High-capacity CFexpress Gold with strong sustained writes for 8K RAW.

- Requires CFexpress Type B reader investment
| Format | CFexpress Type B |
|---|---|
| Max read | Up to 1,900 MB/s |

| Use case rating | 8K RAW and high-bitrate video workflows |
| Warranty | Limited lifetime (region dependent) |
Best for: Cinema and flagship stills shooters who need big capacities for 8K RAW days.
Skip if: You shoot short clips and JPEGs; SD V90 covers you at a fraction of the cost.
Best microSD overall
Samsung PRO Plus microSD
The fast microSD for drones and action cameras: 180 MB/s reads, V30 writes.
PRO Plus is the microSD to buy when the footage matters: V30 plus A2 performance, 180 MB/s reads, six-proof durability and a 10-year limited warranty. Drones, action cameras and handhelds all run at their full bitrate on it.

Best microSD value
SanDisk Extreme microSD UHS-I
The drone and GoPro staple with V30 4K performance and huge capacity options.
Extreme is the card drone and GoPro manuals name because it simply works at V30 bitrates for the lowest sensible price. Buy from authorised sellers to dodge the counterfeit flood and it is the best microSD value in photography.
Strengths
- V30 minimum sustained writes handle 4K action camera bitrates
- Up to 190 MB/s reads with QuickFlow-compatible readers

How we chose
Sustained writes over peak claims
Video and burst performance live at the sustained floor, not the box headline. We ranked V90, V60 and V30 guarantees and published sustained figures first, and treated unspecified cards as burst-only media.
Format matched to camera
A UHS-II card in a UHS-I body runs at UHS-I speeds, and Type B does not fit Type A slots. We framed every pick by the body class that can actually exploit it, so no reader overbuys a bus their camera lacks.
Reliability and support
We weighed construction, serialisation, health monitoring and replacement policies. A card is a single point of failure for irreplaceable work, so warranty behaviour on the worst day outranked small speed differences.
Counterfeit resistance
The best-selling cards here are the most faked products in photography. We favoured lines with strong authorised-channel availability and advised seller discipline throughout, because a fake V90 is worse than an honest V30.
Questions, answered
V30, V60 or V90: which do I need?
Match the card to your codec bitrate. Most 4K up to 400 Mbps needs V30 headroom, high-bitrate All-I and 4K 120p modes want V60 or V90, and 8K RAW belongs on CFexpress. Your camera manual lists the required class per recording mode, so trust it over marketing.
Is a faster card wasted in a slower camera?
For in-camera recording, yes beyond the slot's bus. A UHS-II card in a UHS-I body records at UHS-I speed, though it still offloads faster in a UHS-II reader. Buy for your next body only if an upgrade is imminent.
How many cards should I own?
At minimum two per format you shoot, rotated and formatted in-camera. Professionals carry a day's worth plus a spare set, and never shoot an irreplaceable job on a single unmirrored card.
Should I format in camera or on a computer?
Format in the camera that will shoot the card. It builds the exact file system and folder structure the body expects and is the simplest corruption prevention habit in photography.
