The G7 X Mark II takes a single UHS-I SD card and tops out at 1080p video, so it doesn’t need – or benefit from – the fastest UHS-II cards on the market. These are real UHS-I cards fast and reliable enough to keep up with the camera’s continuous burst mode and 1080p60 clips without paying for more speed than the camera can use.

The picks, in detail
SanDisk Extreme PRO UHS-I
SanDisk’s Extreme PRO line is the fastest UHS-I card on the market and comfortably outruns anything the G7 X Mark II can write.
- UHS-I U3/V30 rated
- Up to ~170MB/s read
- Rugged, waterproof build
- Wide capacity range
- Fastest UHS-I option available
- Excess speed headroom for burst shooting
- Costs more than the camera strictly needs
SanDisk Extreme UHS-I
The non-Pro Extreme trims price while still comfortably covering the G7 X II’s UHS-I write speeds.
- UHS-I U3/V30 rated
- Solid sustained write speed for 1080p video
- Shock/waterproof rated
- Same reliability reputation as the Extreme PRO for less money
- Slightly lower peak speed than the PRO tier (irrelevant for this camera)
Lexar Professional UHS-I
Lexar’s Professional line is a well-established UHS-I performer that keeps up with the G7 X II’s burst and 1080p60 modes.
- UHS-I U3 rated
- Fast sustained write speed
- Included file-recovery software offer
- Reliable, long-running product line
- Retail availability has been less consistent than SanDisk’s in recent years
Kingston Canvas Go! Plus
Kingston’s Canvas Go! Plus targets action and burst shooting, which lines up well with the G7 X II’s continuous shooting mode.
- UHS-I U3/V30 rated
- Rated for 4K on cameras that support it
- Wide temperature tolerance
- Strong reputation for consistent sustained write speed
- Not as widely stocked as SanDisk in every capacity
PNY Elite-X
PNY’s Elite-X is a budget-friendly UHS-I card that still clears the G7 X II’s write-speed needs with room to spare.
- UHS-I U3 rated
- Class 10 speed
- Multiple capacity options
- Lower price point than the big three brands
- Less brand recognition for long-term reliability
Samsung EVO Select
Samsung’s EVO Select is a dependable, widely available UHS-I card that performs well in compact cameras like the G7 X II.
- UHS-I U3 rated
- Waterproof/temperature-proof rated
- Consistent read/write performance
- Reliable performer at a competitive price
- Samsung’s SD line gets less attention than its microSD line
Sony SF-G Tough
Sony’s SF-G Tough is a UHS-II card that’s overkill for the G7 X II’s UHS-I interface, but it’s a legitimately durable option if you’ll reuse the card in a faster body later.
- UHS-II rated (backward compatible with UHS-I slots)
- Reinforced tough construction
- High write-speed ceiling
- Extremely rugged build
- Useful if you upgrade cameras later
- You pay for UHS-II speed the G7 X II can’t use
Buying tips
- The G7 X Mark II’s SD slot is UHS-I only – a UHS-II card will work but won’t write any faster in this camera, so don’t overspend chasing UHS-II speed ratings.
- Look for at least a U3/V30 rating to keep up with the camera’s continuous burst mode without the buffer stalling mid-sequence.
- 64GB is the sweet spot for this camera’s 1080p-only video – 128GB+ mostly matters if you shoot a very high volume of RAW stills.
- Buy from the manufacturer or a listed authorized reseller – SD cards are one of the most counterfeited accessories on marketplaces.
