People tend to focus more on cameras and lenses when discussing camera gear. Those are exciting, fun purchases! However, once a new photographer find themselves out taking photos, the next piece of gear takes center stage, and becomes infinitely more important: memory cards. All digital photographers must use them to store photos, and indeed, you absolutely want to have the best memory cards for photographers or video, that you can possibly get.

Unfortunately, not all memory cards are created equal, and buying the wrong memory card could put your photos at very serious risk! So, that is why you absolutely must understand at least the basics of memory cards… They come in different physical shapes and formats. They come in different storage capacities, of course.

Also, of course, there are different brand names, as well as different transfer speeds and physical durability. Put all this together, and it can be intimidating to consider how it’s actually the memory card, and not your camera or lens, that is the final “point of (potential) failure” in capturing your photos!

When it comes to choosing which are the best memory cards for photographers, it’s worth noting that the answer will change based on each photographer’s needs. Specifically, of course, what camera do you own, but also, what do you photograph?  With that in mind, here’s our guide to help you find the best memory cards for you.

Understanding Different Types of Memory Cards

If you’re new to photography, you should notice early on that your camera does clearly label which type or types of memory cards it can accept. There will always be a basic label on the camera itself, plus the user manual will go into greater detail about memory card compatibility.

Many cameras only take one SD card, and some have two individual slots for two SD cards at once! Other cameras may only take XQD, CFexpress, or other memory cards. Some cameras with dual card slots can use multiple memory card formats at once, such as SD and CFexpress or XQD and SD.

What you still must figure out, however, is which version of the card format that your camera uses is the best memory card to serve your needs. We intend to help you in both areas. Below, we’ll break down different memory card types and look at the strengths and weaknesses of each before sharing our picks for the best memory cards.

SD Memory Cards

SD memory cards

Professional photographers and hobbyists alike use SD (Secure Digital) format memory cards. However, the specific acronym, “SD”, is actually outdated, as you’ll see next. It is important to remember this because you do not simply want to buy any SD card; you need to look for specific types. (Read on!)

SDHC Memory Cards

Again, SDHC (Secure Digital High Capacity) cards are an older type in the SD family. They were ideal for casual and aspiring photographers, or even a professional who may have been working 5-10 years ago. However, SDHC cards only come in 8-32GB capacities, and today we usually recommend 32-64GB as a minimum capacity for most photographers who have a camera with 24 megapixels or more. So, once gain, read on! 

SDXC Memory Cards

SDXC (Secure Digital Extended Capacity) is the current generation of the SD card format. SDXC comes with 64GB and higher capacity, as well as significantly greater speeds.

So, when a fellow photographer asks you, “Hey, can I borrow an SD card?” …they probably mean SDXC. However, again,  when shopping for memory cards, double check to make sure it says SDXC!

The SDXC memory card format is perfect for photographers and videographers of all types, from beginners to professionals. Even if your camera has 40+ megapixels, or captures 4K video, an SDXC memory card should be fine. Unfortunately, there is one more caveat, so read on…

SD Memory Card Speeds (UHS-I, UHS-II, V30, V90, U1, U3, …and more!)

Now, this is where shopping for SD (SDXC) memory cards can get truly confusing and frustrating. Unfortunately, there are multiple ways in which SD card speed is measured/labeled.

If you want the simple answer, as of 2024, make sure that the SD cards you buy are SDXC, UHS-II, U3, Class 10.

With that being said, if you want you can skip to the “XQD” section. If you’re interested in technical details, keep reading…

First, all SD cards have what is called a “Speed Class” rating. The slow, older speed classes are either discontinued and/or irrelevant to modern cameras, so we’ll skip right over the oldest speed ratings, and talk about UHS-I and UHS-II. (UHS stands for Ultra-High Speed)

Start by looking for SD cards with a “U3” rating. By comparison, a “U1” would be practically unusable on modern high-megapixel cameras, because it only guarantees a  transfer speed of 10 MB/s, and cameras these days can capture 50-75+ MB raw files at 10+ frames pre second. Yikes!

So, “U3” SD cards with a UHS-I and UHS-II speed rating are the bare minimum for most photographers. UHS-I should be fast enough for casual photographers, even with high-megapixel cameras. They usually reach up to 200 MB/s read speed, which is very respectable. Professionals or anyone who photographs fast action will likely want UHS-II, which we’ll get to in a minute.

Memory Card Read Speed VS Write Speed

It is important to insert this caveat now: memory cards have two different speed ratings: read speed and write speed! You may see “200 MB/s” displayed prominently on a memory card or packaging, but that could only be its read speed, which is the speed you get when transferring photos to your computer. The write speed, which is how fast your camera can save photos to the memory card, might be a LOT slower, unfortunately! So, always read the fine print when shopping for SD memory cards, and check both the read and write speeds. These days, most all photographers will want an SDXC UHS-I or UHS-II card that reaches 200-300 MB/s transfer speeds.


Photographers who do a lot of high-speed or near-constant shutter clicking, (or high-quality 4K video) will want to shop exclusively for UHS-II SD cards. The best ones can offer not just 300 MB/s read speed, but also an impressive 299 MB/s write speed. (Impressive for SD, that is…)

Unfortunately, as if that wasn’t complicated enough, there is one more thing: a video-centric speed rating: “V30” or “V60”. Thankfully, this “V” rating is a bit more straightforward: V30 means a minimum of 30 MB/s write speed. V90, for example, means a minimum write speed of 90 MB/s.

Memory Card “X” Speed Ratings

A few memory card brands, (mostly Lexar) still also use yet another unhelpful speed rating, such as “1667X” or “1800X”. Unfortunately, these numbers don’t mean very much! Also, again, they might only be the read speed, not a write speed. Therefore, we recommend ignoring these numbers completely; just look closely for the read & write speeds.

microSDHC and microSDXC

The microSDHC and microSDXC formats are perfect for camera phones and action cameras, but we don’t generally recommend them for professional cameras because you’ll be relying on a (cheap plastic) adapter to write and read every single one of your photos.

Outdated: CompactFlash Memory Cards

Another card format that is becoming rarer because of upgraded versions is the CompactFlash. Before, this memory card format was common for almost all high-end DSLRs. However, the capacities and speed of SDHC and SDXC have made CF an outdated memory card format.

Outdated: CFast Cards Memory Cards

Don’t be fooled! The CFast memory cards are not compatible with the Compact Flash format, despite sporting the same structure and size. The CFast cards are known for being significantly higher speed than CF, however, both are now relatively obsolete. If you own a slightly older camera that uses CFast cards, or are considering buying one, you’ll want to keep this in mind.

XQD Cards

These memory card formats are limited only to some Nikon DSLRs, mirrorless cameras, and Sony camcorders. At this point, camera manufacturers are not leaning toward this format, because CFexpress cards supersede it. But, XQD Cards are known for impressive performance for video recording and high-speed photography.

CFexpress Cards

best memory cards for photography 06

For a high-speed, professional memory card, the current industry standard is CFexpress. Unfortunately, this memory card format is only available for selected high-end cameras such as the Sony A1, Nikon Z9, and Canon R3, plus a few others.

CFexpress cards come in two types: Type A and Type B. These two types are not interchangeable, and a camera that allows only a Type A card cannot operate with a Type B format, or vice versa.

CFexpress type A memory cards are unique in that they are physically similar to SD cards, though not exactly. A few cameras can accept both SDXC and CFexpress type A; mainly Sony, plus some Canon, but not all. CFexpress type B memory cards, on the other hand, share physical dimensions and connection formats with XQD; so, some cameras are compatible with both. (Mainly Nikon)

With these two different versions of the same memory card, (by name at last) it is definitely important to pay very close attention to which type of CFexpress card you are buying, and making sure it is compatible with your camera. Having said that, virtually all CFexpress cards are blindingly fast, with transfer speeds measured (theoretically) in the 1000’s of MB/sec.

NOTE: CFexpress type A cards have a theoretical maximum speed of 1000 MB/sec, while CFexpress type B cards reach up to 2000 MB/sec. Both are adequate for almost all types of photography

Conclusion | The Best Memory Card For Your Camera

best memory cards for photography 02

Despite the overwhelming variety of memory cards available, your camera manufacturer will always be a reference point for which format to choose. You don’t have to get out your user manual every time you shop for a new memory card, though; just go by the guidelines outlined in this article, and the label on your memory card door.

Beyond that, the best memory cards for you as a photographer will depend on the genre of photography you shoot, as well as the frequency. Wedding photographers will potentially capture thousands of photos per week, for example, and will require more storage, faster speeds, and long-term durability. Most photographers, whether doing professional portraits or casual vacations or everyday photography, will get the best value out of owning just two (since everybody needs a backup, pro or not) …of whichever offers enough storage space and physical quality.

Knowing your own specific needs will give you criteria for your budget, storage capacity, and speed.  We hope that this list helps you with your search for the best memory cards. If you have a top pick that didn’t make a list, let us know in the comments below.
