Detailed UHS-II SD Card Reviews (January 2026)

1. SanDisk Extreme Pro V90 – Fastest UHS-II Card for 8K Video

The SanDisk Extreme Pro V90 consistently delivered the fastest write speeds in our testing, hitting nearly 280MB/s sustained writes during 8K recording sessions. When I shot a 45-minute continuous 8K take on a Sony FX6, this card never throttled while other V90 cards dropped to 200MB/s after 15 minutes.

Customer photos validate the premium build quality, with the distinctive black and red design that SanDisk has perfected for professional media. The card feels solid in hand, and the IP68 rating means it can survive being dropped in water or exposed to dusty environments that would destroy lesser cards.

During my burst photography tests with a Canon R6 Mark II firing at 20 fps, this card cleared buffers nearly twice as fast as V60 cards. I captured 120 RAW files in 6 seconds with zero lag, where V60 cards started choking after 40 shots.

The 256GB capacity stores approximately 352 minutes of 4K UHD video at 60fps or 286 minutes of 8K video at 30fps. For sports photographers using best mirrorless cameras for sports, this capacity means you won’t need to swap cards during a critical game.

Who Should Buy?

Professional videographers shooting 8K or high-bitrate 4K, sports photographers needing maximum burst performance, and anyone who shoots in harsh environments where water and dust resistance matter.

Who Should Avoid?

Photographers whose cameras don’t support UHS-II, casual shooters who don’t need sustained write speeds, and anyone on a tight budget.

2. Lexar Professional 2000x – Best Premium V60 for 4K Video

Lexar’s 2000x card punches above its weight class, delivering V90 performance at a price that undercuts SanDisk and Sony. During my testing, the card maintained consistent write speeds during 4K 60fps recording on a Panasonic GH6, never dropping frames even in long takes.

The 64GB capacity is ideal for shorter shoots or as a backup card. Real-world user images show the distinctive black and gold Lexar design that looks professional and is easy to identify in a camera bag full of media.

I noticed PC transfer speeds were slightly slower than some competing V90 cards, averaging about 250MB/s versus the 280MB/s I got from SanDisk. However, in-camera performance was excellent, with buffer clearing times that matched more expensive cards.

Some Windows users reported compatibility issues requiring a Mac for file transfers, though I didn’t encounter this problem during my testing with a Windows 11 PC and Lexar’s own card reader.

Who Should Buy?

3. Sony Tough G Series – Most Rugged UHS-II Card

The Sony Tough G series is built like a tank, with a one-piece molded construction that eliminates the weak points found in traditional SD cards. During my testing, I accidentally stepped on this card (don’t ask), and it continued working perfectly. Sony claims it’s 18 times stronger than standard SD cards, and after seeing customer photos of bent cards that still function, I believe it.

The ribless design removes the write protection switch entirely, which is brilliant because that tiny plastic tab is the number one failure point on traditional SD cards. No more worrying about breaking off the switch or having it slide into the locked position at the worst possible moment.

Thermal performance impressed me during extended video shoots. The card ran noticeably cooler than V60 alternatives, with my Sony FX3 reporting a 5-degree temperature difference during a 30-minute 4K 120fps recording. This heat management translates to more consistent performance and potentially longer card lifespan.

The completely sealed monolithic structure earns IPX8 waterproof and IP6X dustproof ratings. Customer photos show the card surviving drops onto concrete and even brief submersion, though I didn’t intentionally destroy mine to verify.

Who Should Buy?

Travel photographers shooting in harsh conditions, outdoor sports photographers, news photographers who need gear that survives anything, and anyone tired of babying their SD cards.

Who Should Avoid?

Studio photographers who never leave climate-controlled environments, budget-conscious shooters, and users who don’t need extreme durability.

4. ProGrade Digital V90 – Best for Cinematic Cameras

ProGrade Digital was founded by former SanDisk executives, and that heritage shows in this card’s video-focused design. The standout feature is constant write speed performance that doesn’t fluctuate, which is critical for cinematic cameras recording All-In-One formats that demand consistent data rates.

Every card undergoes 100% testing before leaving the factory, with serialized tracking of components and manufacturing data. This quality assurance shows in the reliability, with multiple users reporting years of trouble-free use including wedding filmmakers and documentary shooters.

The Refresh Pro software (sold separately) lets you monitor card health and restore performance over time, a unique feature that extends the card’s lifespan. I tested this on a card that had been heavily used for six months, and the refresh process restored write speeds to near-new levels.

Write speeds top out at 250MB/s, slower than the 299MB/s of Sony Tough or 300MB/s of SanDisk Extreme Pro. However, the sustained nature of these writes means better real-world performance for video than cards with higher peak speeds that throttle under sustained load.

Who Should Buy?

Cinematic camera users (Sony FX series, Canon C70, RED Komodo), filmmakers who value consistent performance over peak specs, and professionals who want health monitoring for their critical media.

Who Should Avoid?

Still photographers prioritizing burst speed over video performance, users who don’t want to buy proprietary card readers, and anyone who never shoots video.

5. SanDisk Extreme Pro V60 – Best SanDisk V60 Value

This card sits in the sweet spot between performance and price for most photographers. The V60 rating guarantees minimum 60MB/s sustained writes, which is sufficient for 4K 60fps and even 6K video on many cameras. During my testing with a Canon R6 Mark II, it handled 4K 60fps recording without any dropped frames.

The 4.9-star rating from nearly 3,000 reviewers speaks volumes about reliability. Customer images show the card in action across various cameras, with users consistently praising its bulletproof performance. I put it through a stress test of 500 RAW photos in burst mode followed by 20 minutes of 4K video, and it never faltered.

SanDisk’s 7-proof protection includes water, shock, temperature, X-ray, magnet, drop, and vibration resistance. While not as rugged as the Sony Tough series, this protection is sufficient for most shooting conditions short of war zones.

The 280MB/s read speed significantly speeds up file transfers. I offloaded 120GB of files in about 7 minutes using a UHS-II reader, compared to nearly 15 minutes with UHS-I cards. For landscape photography where you might fill multiple cards during a sunrise shoot, this time savings adds up.

Customer photos demonstrate the card’s compact size relative to camera bodies, and several users have tested it successfully in cameras ranging from Sony Alpha series to Nikon Z bodies with no compatibility issues.

Who Should Buy?

Hybrid photo/video shooters, enthusiasts moving from UHS-I to UHS-II, and anyone wanting V60 performance without V90 pricing.

Who Should Avoid?

Sports photographers needing maximum burst clearing, 8K videographers, and anyone whose camera requires V90 for high-frame-rate video.

While rated for 180MB/s writes, my tests showed sustained speeds around 60MB/s during continuous recording, which is still sufficient for V60 requirements. The card maintains consistent performance without the throttling I’ve seen from some competitors during long takes.

Who Should Buy?

Sony camera users especially FX30/A6700 owners, videographers needing 256GB capacity, and shooters wanting reliable performance at a good price.

Who Should Avoid?

Users whose cameras require V90 for high-frame-rate video, extreme burst photographers, and anyone needing maximum write speeds.

8. Sony Tough M Series – Best Mid-Range Tough Card

The Sony Tough M series brings the legendary Tough build quality to a more accessible V60 price point. You get the same one-piece monolithic construction as the G series, just with slightly lower speeds that are still excellent for most professional applications.

Customer photos consistently highlight the card’s durability, with users sharing stories of cards surviving drops, water exposure, and even being run through washing machines (though I don’t recommend testing that). The 18x strength advantage over standard cards provides real peace of mind for travel and outdoor shooting.

The absence of a write-protect switch eliminates a major SD card failure point. Traditional cards commonly fail when this tiny plastic tab breaks off, but Sony’s ribless design removes this vulnerability entirely.

During my testing, I transferred a full 128GB card in under 10 minutes using a Sony UHS-II reader. The 277MB/s read speeds are among the fastest in the V60 category, significantly reducing post-production downtime.

Some users note the tight fit initially, which requires slightly more force to insert and remove. This snug fit actually prevents accidental ejection, and I found it smoothed out after a few weeks of regular use.

Sony’s customer support impressed me when they proactively reached out about a firmware update for older Tough M cards that had known corruption issues. This level of support builds customer loyalty and justifies the premium pricing.

Who Should Buy?

Travel photographers, outdoor shooters, professionals who value durability above all else, and Sony camera users wanting brand-matched reliability.

Who Should Avoid?

Indoor studio photographers, budget-conscious buyers, and anyone who doesn’t need extreme durability.

10. Kodak Ultra Pro – Best Budget UHS-II Card

The Kodak Ultra Pro is the most affordable legitimate V60 UHS-II card on the market. During my testing, read speeds actually exceeded the rated specs, hitting 267-293MB/s depending on the reader used. Write speeds held steady at the advertised 100MB/s, which is sufficient for V60 requirements.

At less than half the price of premium V90 cards, this delivers UHS-II performance for budget-conscious enthusiasts. Customer photos show the card in various camera setups, with users confirming it handles 4K recording and RAW burst photography without issues.

I ran integrity tests that wrote and read the entire card capacity twice, with zero errors or corrupted files. For a budget card, this reliability is impressive and suggests Kodak has good quality control despite the lower price point.

The nostalgic Kodak branding appeals to photographers who remember the company’s film legacy. While Kodak doesn’t manufacture these cards (they’re licensed), the brand has been careful about maintaining quality according to user reports.

The 2-year warranty is shorter than the lifetime coverage from Lexar or SanDisk, which reflects the budget positioning. However, user reports of failures are rare, suggesting these cards are reliable despite the shorter warranty period.

Who Should Buy?

Budget-conscious photographers wanting UHS-II speeds, enthusiasts upgrading from UHS-I, and anyone who wants legitimate performance without premium pricing.

Who Should Avoid?

Professionals who can’t risk shorter warranty coverage, 8K videographers, and users who need maximum write speeds.

Understanding UHS-II Technology

UHS-II (Ultra High Speed Type II) cards feature two rows of electrical pins instead of the single row found in UHS-I cards. This dual-lane architecture allows for parallel data transfer, effectively doubling the theoretical maximum bandwidth from 104MB/s (UHS-I) to 312MB/s (UHS-II).

The second row of pins is what makes UHS-II special. When both camera and card support this dual-lane communication, data flows simultaneously through both channels, dramatically reducing buffer clearing time and enabling higher sustained write speeds for video recording.

However, UHS-II cards are backwards compatible. They’ll work in UHS-I-only cameras, but they’ll default to single-lane UHS-I speeds. This is important to know: buying a UHS-II card won’t magically make your older camera faster if it doesn’t support the interface.

The physical difference is visible: UHS-II cards have two rows of pins on the back, while UHS-I cards have only one row. This extra row is what enables the dramatic speed increase that professional videographers and sports photographers rely on.

Buying Guide for UHS-II SD Cards

Choosing the right UHS-II card requires understanding your specific shooting needs. Let me break down the key factors based on my testing experience.

V60 vs V90: Which Speed Class Do You Need?

The video speed class (V60 or V90) indicates minimum sustained write speed, not maximum. V60 guarantees at least 60MB/s sustained writes, while V90 guarantees 90MB/s. This sustained speed is what prevents dropped frames during video recording.

Speed Class	Minimum Write	Best For	4K 60fps	8K Video
V60	60MB/s	4K video, photography	Yes	No
V90	90MB/s	8K, high-bitrate 4K	Yes	Yes

For most photographers and 4K videographers, V60 is sufficient. You need V90 if you’re shooting 8K, high-frame-rate 4K (120fps+), or high-bitrate codecs like All-I or ProRes. Otherwise, you’re paying for performance you won’t use.

Solving for Burst Photography: Look for High Write Speeds

Sports and wildlife photographers need cards that clear buffers quickly. Write speed matters more than read speed here: a card with 250MB/s writes will clear your camera’s buffer significantly faster than a card with 100MB/s writes, regardless of read speeds.

When shooting burst photography, pay attention to real-world write speeds rather than just the V-rating. Some V60 cards with high write speeds outperform V90 cards with lower write speeds for burst photography.

Solving for Video Recording: Match Card to Bitrate

Every camera has a maximum bitrate for each video format. Check your camera’s specifications and choose a card that exceeds that bitrate with headroom. For example, if your camera records 4K at 200Mbps, you want a card with at least V60 rating (60MB/s = 480Mbps) to ensure reliable performance.

Solving for Durability: Consider Your Shooting Environment

If you shoot outdoors, travel frequently, or work in challenging environments, durability features matter. Sony Tough series cards offer the best physical protection with their one-piece design, but SanDisk’s 7-proof protection is also excellent for most conditions.

Waterproof ratings matter if you shoot near water or in rainy conditions. IPX8 means the card can survive continuous immersion, which I’ve tested accidentally more than once.

Solving for Workflow: Don’t Forget the Card Reader

All the speed of your UHS-II card is wasted if you’re using a slow card reader. For Intel Windows laptops with high-speed USB ports, invest in a quality UHS-II card reader to maximize transfer speeds.

I tested file transfers with various readers and found differences of up to 40% between cheap readers and quality ones from ProGrade, SanDisk, or Lexar. The reader matters as much as the card for transfer speeds.

Solving for Budget: When to Save vs. Splurge

V60 cards offer better value for most users. Only spring for V90 if you genuinely need the sustained write speeds for 8K or high-frame-rate video. Otherwise, a quality V60 card will serve you just as well for a fraction of the price.

Watch for seasonal SD card discounts during Black Friday and holiday sales. Premium cards often see 20-30% discounts during these periods, making it the best time to stock up on professional media.
