The Ricoh G900 isn’t demanding: any current SD/SDHC/SDXC card from a major brand handles it, with V30 (U3) giving comfortable headroom for its 4K30 video. Picks below, plus sizes and in-camera formatting.
The Ricoh G900 camera doesn’t come standard with a memory card as standard. Some retailers sometimes put together bundles that might include an SD card, but chances are you’ll have to pick up a memory card separately. So the natural question is: what’s the best SD card to get for it?
If you just want to cut to the chase, here are some quick recommendations. Any of these is a good choice for the G900. They’re compatible with all of the camera’s features, they’re from reliable and well-known memory card manufacturers, they’re readily available at major retailers, and they can often be found at reasonable prices. You can find more information on these further down this page.

Ricoh G900 memory card requirements
So which SD card should you get for your G900? The specs and manual are pretty light on specifics, but the gist is:
- SD/SDHC/SDXC or FlashAir
And yes, that’s about it.
The reason for that is that the G900 is not especially demanding on the speed of the SD card, at least by current standards. It does have 4K30 video and HDR video modes, though, so there are cards that will be too slow to keep up.
Worth noting: FlashAir is a variation on SD cards developed by Toshiba. It conforms with SD specs but adds wifi capabilities, like the now-discontinued Eye-Fi cards. While it is still technically possible to buy FlashAir cards, the ones I’ve come across are absurdly expensive and therefore simply don’t make a good choice. Which is why I’m not including any here in these recommendations.
Something to point out is that, like other Ricoh cameras, the G900 does have some user-accessible internal memory. And, at 6.5GB, it’s surprisingly large. But it’s not really large enough to be a viable replacement for a memory card. It’s best used as a kind of backup if the SD card happens to fill up.
So what I’m aiming to do here is provide some practical recommendations on which SD cards to get for the G900 so you can spend less time searching online and more time out shooting.
I’m not trying to list every SD card that works in the G900 — there are many others that will work just fine as well. I’m focusing here on ones that offer a good combination of meeting the requirements of all of the G900’s features, are readily available at major retailers, are cost-effective, and come from major manufacturers with track records for good-quality cards. And, because the G900 just doesn’t need–and can’t take full advantage of a fast SD card–there’s no point forking out the big bucks for a cutting edge fast SD card.
So here are some more specific recommendations:
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

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!).

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.

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.

What size SD card to use in the Ricoh G900
The G900 is compatible with SDHC and SDXC cards. That means you can use cards from 4GB all the way to the largest cards currently available, which are 512GB and even 1TB cards. The current sweet spot for a combination of convenience, being readily available, and being cost-effective is probably around the 128GB to 256GB cards. And given that this camera really lends itself to traveling, the larger cards will give you more flexibility with much less risk of running out of space partway through a trip (but you can also obviously take a spare or download your photos and videos on the road).
How to format memory cards in the Ricoh G900
The G900 has separate functions for formatting the SD card and the internal memory. To format the SD card, go to:
Setup > Format [Card]You can find the function to format the internal memory directly under that.
How to format SD cards with a computer
It’s always best practice to format memory cards in the camera you’re planning to use them in, but if that’s not practical or not what you want to do, it is possible to format them with a computer. But there are some things to watch out for, particularly when it comes to choosing which filesystem to use. So I’ve put together guides on how to format SD cards on Mac and how to use the free SD Card Formatter app for Windows or Mac.
