Sony RX100 VII memory card compatibility & requirements
If you’re wondering how large a card the RX100 VII can handle, Sony’s own documentation only lists capacities up to 256GB by name, though owners have reported no problems running larger 512GB and even 1TB SDXC cards in it. There’s no official upper limit stated by Sony beyond the SDXC standard itself, so capacity isn’t really the thing to optimize for here — speed class is.
A memory card is an essential accessory for the Sony RX100 VII. Without it, you’re not going to be able to take many photos or shoot much video.
The Sony RX100 VII is a pocket-sized camera in Sony’s Cyber-shot series. But the size is deceptive — this camera packs a 20-megapixel 1-inch sensor and shoots 4K30 video at up to 100Mbps.
The RX100 VII has a single UHS-I SD card slot, and it’s compatible with SDXC, SDHC, and SD cards.
microSD cards will work in the RX100 VII, but only inside a full-size SD adapter. Sony’s manual is blunt about this: drop a bare microSD card into the slot and you may not be able to get it back out. The adapter is also one more contact point that can work loose, so if you have the choice, buy a full-size SD card and keep the microSD-plus-adapter route for when it’s all you have.
Sony RX100 VII memory card recommendations in detail
So which SD card should you get for your Sony RX100 VII? Here’s a more detailed explanation.
The RX100 VII’s instruction manual offers some guidance, but it can be vague. For our purposes here, I’m focusing on memory cards that will let you use all of the Sony RX100 VII’s features.
I’m focusing here on Secure Digital (SD) cards. While the camera is compatible with Sony’s Memory Stick format, those cards generally do not support the 100Mbps bitrate required for the highest quality 4K video. By contrast, modern SD cards easily handle this data rate.
These cards are all rated V30 and work well in a very wide variety of cameras, with good versatility for shooting photos and 4K video.
My emphasis here is on cards that meet these criteria:
- They're fast enough for all the features of this camera.
- They're from a reputable and reliable brand, so you can count on them working well.
- They're readily available at major retailers, so you should be able to find them without much trouble.
- They're good value for money, so you're not paying too much for a card that is more than your camera can take full advantage of.
If you want to use a faster, fancier card, you can, but you won't see any extra benefit in doing so while you're operating the camera (but you might see some faster speeds when downloading the photos to a computer, depending on your computer and memory card reader combination). And, as always, I recommend buying from a major retailer to minimize the chances of getting burned with a counterfeit memory card.
SanDisk Extreme V30 UHS-I
- Type: SDXC / SDHC
- Video Speed Class: V30
- UHS Bus Interface Type: UHS-I
- Maximum Read Speed: 230 MB/s
- Storage Capacities: 32GB, 64GB, 128GB, 256GB, 512GB

SanDisk's Extreme range are good bets for many cameras, and that's true here too. SanDisk has faster ranges, like the Extreme Pro line, but this Extreme line is both quick enough for most cameras and usually less expensive than those faster cards.
One thing to note with SanDisk cards is that they recycle their model names. So you can find Extreme cards that are older and slower. You'll probably find those older versions work just fine — it really depends how far back you go. I've used many SanDisk Extreme cards over the years in many different cameras and have found them to be very reliable. They're also often good value, and you can sometimes find them sold in 2-packs (it's always good to have a spare on hand!).
Lexar High-Performance 800x PRO BLUE Series V30 UHS-I
- Video Speed Class: V30
- UHS Bus Interface Type: UHS-I
- Maximum Read Speed: 150 MB/s
- Storage Capacities: 64GB, 128GB, 256GB
Check current price and availability at:
The Lexar 800x Pro range is a relatively new model that replaces the old 633x cards that were mainstays of Lexar's SD cards for a long time. This newer V30 card is still a good combination of speed, reliability, and value, and you can often find them in multipacks to have spares on hand.
Delkin Devices ADVANTAGE V30 UHS-I SDXC (180 MB/s)
- Type: SDXC
- Video Speed Class: V30
- UHS Bus Interface Type: UHS-I
- Maximum Read Speed: Up to 180 MB/s
- Storage Capacities: 128GB, 256GB, 512GB, 1TB

Delkin Devices have recently come out with a range of new SD cards of varying speeds and specs. This is one of their mid-range cards that is rated for V30 video recording speeds. This newer version is rated for read speeds of up to 180 MB/s (the older version of the Advantage maxxed out at 90 MB/s).
Nextorage Classic V30 UHS-I SDXC Card
- Type: SDXC
- Video Speed Class: V30
- UHS Bus Interface Type: UHS-I
- Maximum Read Speed: Up to 200 MB/s
- Storage Capacities: 128GB, 256GB, 512GB

Japanese brand Nextorage makes excellent memory cards, although they're not always easy to find in stores in the US. But if you can find them, in my experience they're a very good bet. This is their basic (or "Classic") model, rated for V30.

Making sense of SD card specifications
SDHC vs. SDXC: Why you want 64GB+
Most of the cards you’ll see available now have either SDHC or SDXC printed on them.
The practical difference is capacity. Cards 32GB and smaller are labeled SDHC and use the FAT32 file system. Cards 64GB and larger are labeled SDXC and use the exFAT file system.
Recommendation: Use SDXC cards (64GB or larger). Why? Not because a 32GB SDHC card locks you out of a video mode — Sony’s own card table allows SDHC for XAVC S 4K at 100Mbps as long as the card is U3-rated. The real reason is the file system. SDHC cards use FAT32, which can’t hold a single file bigger than 4GB, so Sony’s manual notes that a long XAVC S clip recorded to an SDHC card gets split into 4GB pieces that you then have to rejoin on the computer. SDXC cards use exFAT and keep the clip as one file, and 64GB or larger also gives you sensible room for 100Mbps footage.
UHS-I vs. UHS-II: Don’t overpay
The Sony RX100 VII has a UHS-I interface. While you can use the faster and more expensive UHS-II cards (the ones with the second row of pins), you won’t see any speed benefit inside the camera. Save your money and stick to high-quality UHS-I cards.
It’s also worth ignoring the big speed number printed on the front of the card. A card badged 170MB/s won’t hit that in this camera — the UHS-I bus tops out around 104MB/s, and those headline figures are read speeds measured in a fast card reader, not write speeds. The U3 or V30 rating is the number that tells you whether the card can keep up while recording.
Video Speed Classes: Look for U3
To shoot 4K video at 100Mbps on the RX100 VII, Sony requires a card that is rated UHS Speed Class 3 (U3). You will see this symbol as a ‘3’ inside a U-shape bucket on the card.
Most modern cards also carry the V30 (Video Speed Class 30) rating, which is effectively the same speed guarantee.
Any card with a U3 or V30 symbol is fast enough for everything this camera can do.
How to format an SD card in the Sony RX100 VII
It is best practice to always format memory cards in the camera that you’ll be using them in. This sets the card up with the correct database file structure.
On the Sony RX100 VII, you can find the format function under:
MENU > Setup (Toolbox icon) > Format
