Why Is the Right Memory Card Important?
No memory card, no photos — it’s an often underestimated but essential part of your camera gear. The memory card stores all your photos and videos and therefore needs to be chosen carefully.
A bad or too-slow card can be a real headache: your camera takes forever to save data, or you suddenly run out of storage space. To avoid moments like these, picking the right memory card is almost as important as choosing the camera itself.
With the right card, you save yourself a lot of frustration and can focus entirely on shooting photos or video.
What Should You Look for When Buying a Memory Card for Your Camera?
When buying a memory card, the most important thing is what your camera supports. Your camera determines the format and the basic requirements of the card — so you don’t have complete freedom of choice here. But don’t worry, we’ll help you navigate the storage jungle!
Type of Memory Card
First things first: which card type does your camera support?
Most cameras today use SD cards, while professional models often require CFexpress cards. Some compact devices like drones or action cameras rely on Micro SD cards.
Which card is right for you is listed in your camera’s manual or often directly next to the card slot.
Important: Only the matching formats and types will work. Make sure you pick the right card to avoid unnecessary returns.
What Do SDHC and SDXC Mean?
You may have already come across the abbreviations SDHC or SDXC on your camera or a memory card. These two terms say nothing about the speed or quality of the card — only about the storage type and the maximum capacity.
- SDHC stands for “Secure Digital High Capacity” and covers cards from 4 GB to 32 GB.
- SDXC stands for “Secure Digital eXtended Capacity” and covers the range from 64 GB to 2 TB.
The difference is purely technical — the one thing that matters: older cameras sometimes only support SDHC cards. Your camera’s manual will tell you which types are compatible. Modern cameras can generally read and write both formats without any issues.
Speed
Speed is super important — it determines how quickly your camera saves data after each shot.
The card format your camera supports already gives you a rough idea of how fast the card needs to be.
UHS-I cards are on the slower side, while CFexpress cards are genuinely fast. But even within card types, there are faster and slower models depending on what you need.
Pay attention to the write and read speeds — these are usually printed directly on the card. UHS-I cards offer write speeds of about 10 to 90 MB per second, UHS-II cards come in at 150 to 300 MB per second, and CFexpress cards reach an impressive 400 to over 1,500 MB per second.
For SD cards, the V-rating system (V30 to V90) is a handy guide: V30 means the card can write 30 MB per second, which is more than enough for Full HD video. For 4K video or fast burst shots, go with a V60 or V90 so the camera can keep up.
Storage Capacity
How much storage you need depends entirely on how you shoot. Are you photographing while traveling or filming in high resolutions? Then a higher-capacity card makes sense.
- 64 GB: Perfect for hobbyist photographers who mainly shoot JPEGs.
- 128 GB or 256 GB: Ideal if you shoot in RAW or film in 4K. Better to have a little more storage than too little — there’s almost nothing more frustrating than running out of space mid-shoot!
If large cards feel too risky, you can also use multiple smaller cards. That way you always have a backup on hand in case one card fails.
Compatibility
Not every memory card fits every camera. CFexpress cards are more common in high-end models, while SD cards are used across all price ranges.
Your camera’s write speed should also match the card — there’s no point in buying a super-fast UHS-II card if your camera only supports UHS-I.
Always check what your camera needs and can actually handle before you buy.

Old Memory Cards – These Types Are No Longer Current or Very Rare Today
In the world of memory cards, there are also older formats that have since been replaced by more modern and faster options. Here’s a quick overview of the formats you’re unlikely to need:
The dinosaurs of memory cards are CF or CompactFlash cards — once popular, but now replaced by modern formats like SD and CFexpress. They’re only used in a very small number of cameras anymore, and finding new models has become quite difficult.
With the decline of DSLR cameras, manufacturers experimented with new formats. XQD and CFast cards showed early promise but are barely being developed any further today. Both have since been replaced by the faster and more versatile CFexpress cards, which have established themselves as the standard for high-end cameras.
Conclusion – Which Memory Card Is Right for You?
The most important first step is checking which memory cards are actually compatible with your camera.
From there, think about how much storage space you really need and whether you want a particularly fast or durable card. Depending on your needs, you can then decide between a premium model or a more affordable alternative — both will do the job as long as they match your camera and how you shoot.

Frequently Asked Questions About Memory Cards
Which memory card is best for 4K video recording?
For 4K video, high write speed is essential so data can be transferred to the card fast enough.
If your camera uses SD cards, go with a UHS-II card — write speeds of around 150 to 300 MB per second are enough for most 4K recordings.
If your camera supports CFexpress, you’ll be really well equipped: write speeds of 400 to over 1,500 MB per second handle even the highest bitrates and longer clips without breaking a sweat.
How much storage space do I need for my photography?
It really depends on how you shoot! For hobbyist photographers who mainly take JPEGs, a 64 GB card is often more than enough.
If you shoot in RAW or record 4K video, plan for at least 128 GB — especially if you’re traveling for an extended period.
Honestly, better to have a little too much storage than too little. You really don’t want to miss a shot because your card is full!
What is the difference between SD UHS-I and UHS-II?
In short: UHS-II is faster. While UHS-I cards max out at around 104 MB/s, UHS-II cards can reach up to 312 MB/s.
That makes a real difference when shooting lots of images in burst mode or transferring large video files to your computer. If your camera supports UHS-II, the upgrade is absolutely worth it!
Can I use a Micro SD card in my camera?
Yes, but it depends. With an SD adapter, you can use Micro SD cards in most cameras.
That said, Micro SD cards are generally not as durable or as fast as regular SD cards.
They’re great for action cameras or drones, but for high-quality photos and videos we’d recommend sticking with a classic SD card.
Why are CFexpress cards so expensive?
CFexpress cards are true high-tech storage media — ultra-fast, extremely rugged, and built for professionals working with high-resolution images or 8K video.
The high price reflects both the complex manufacturing process and the fact that these cards are still relatively new to the market. They’re currently used mainly in high-end professional cameras, which keeps them in niche territory.
That said: if you have a camera that supports CFexpress and you want to get the most out of it, they’re definitely a worthwhile investment.
