Quick Take
SDHC and SDXC are capacity standards, not speed ratings. SDHC covers cards from 4GB to 32GB (FAT32); SDXC is everything from 64GB up (exFAT). Every modern camera and phone takes SDXC ā buy SDXC unless a very old device specifically requires SDHC.
When shopping for a memory card, youāll often come across Micro SDHC vs Micro SDXC labels.
At first glance, they might seem almost identical, but there are key differences that affect storage capacity, performance, and compatibility.
If youāve ever been confused about which one to choose for your camera, phone, or gaming console, this guide will break down everything you need to know.
By the end, youāll have a clear understanding of Micro SDHC vs Micro SDXC cards and which one suits your needs best.
What is Micro SDXC?
Micro SDXC (Secure Digital eXtended Capacity) cards are designed for high storage and fast performance. If youāre working with large files, recording in 4K, 5K, or even 8K resolution, or need extra space for high-resolution photography, a Micro SDXC card is your best bet.
Storage Capacity
Micro SDXC cards start at 64GB and go up to 1TB (and beyond, as new models are released). This makes them ideal for professional cameras, drones, and gaming consoles that require high-speed storage for large media files.
Performance and Speed
Most Micro SDXC cards offer UHS-I or UHS-II speed classifications, meaning they support fast read and write speedsāoften exceeding 90MB/s. This is crucial for tasks like recording high-bitrate videos or shooting RAW photos in burst mode.
Best Uses for Micro SDXC
- Professional photography & videography (DSLRs, mirrorless cameras, drones)
- Action cameras (GoPro, Insta360)
- Gaming consoles (Nintendo Switch, Steam Deck)
- Smartphones & tablets for high-performance apps
Here are some top-rated Micro SDXC cards available on the market:

The SanDisk Extreme Pro SDXC is one of the best high-performance memory cards you can get. It supports 4K video recording, has a 90MB/s write speed, and 95MB/s read speed, making it a top choice for professional photographers and videographers.

The Samsung EVO Select Micro SDXC is a great option if you need high storage but donāt want to break the bank. It features 95MB/s transfer speeds, but with a 20MB/s write speed, itās more suited for casual users rather than professionals working with RAW files.
What is Micro SDHC?
Micro SDHC (Secure Digital High Capacity) cards are designed for smaller storage capacities. These are the cards most commonly used in budget cameras, mobile devices, and gaming consoles.
Storage Capacity
Micro SDHC cards are available in 8GB, 16GB, and 32GB sizes. If you donāt need a ton of space and mostly work with 1080p video or basic photography, an SDHC card will work just fine.
Performance and Speed
Since they have a smaller capacity, SDHC cards tend to be slower than SDXC. Many SDHC cards are Class 10 (10MB/s write speed), meaning they can handle basic Full HD (1080p) video recording, but they may not be ideal for high-bitrate 4K footage.
Best Uses for Micro SDHC
- Basic point-and-shoot cameras
- Smartphones and tablets with expandable storage
- Older gaming devices (Nintendo 3DS, PSP)
- Security cameras (Wyze Cam, Blink, Arlo, etc.)
Here are some of the best Micro SDHC cards available:

FAQ
Can I use a Micro SDXC card in a device that supports Micro SDHC?
No. SDHC devices only support up to 32GB storage, so an SDXC card wonāt work unless the device explicitly states that it supports both formats.
Can I format a Micro SDXC card to work as an SDHC?
Technically, you can format an SDXC card to FAT32 (which SDHC uses), but this will limit its performance and features. Itās better to use the card in a device that fully supports SDXC.
Whatās the best SD card for a GoPro or drone?
GoPro and drones require high-speed UHS-I or UHS-II SDXC cards. Some of the best choices include:
- SanDisk Extreme Pro SDXC
- Samsung EVO Select SDXC
- Lexar Professional 1066x SDXC
Is an SDXC card worth it for a smartphone?
If your phone supports expandable storage, an SDXC card with A2 rating is a great choice. It helps with faster app loading and better performance.
Which SD card is best for 4K video recording?
For 4K video, you need an SDXC card with at least V30 (30MB/s write speed) or higher. Some top options include:
- SanDisk Extreme Pro
- Samsung EVO Select
- Lexar Professional 1000x
Which One Should You Get?
If you need more than 32GB and plan to record in 4K or higher resolutions, go with Micro SDXC. Itās the best choice for cameras, drones, and gaming consoles that require high-speed storage.
If you just need a budget-friendly option for basic 1080p video or everyday storage, then Micro SDHC will work fine.
Choosing the right SD card depends on your specific needs, so make sure you check compatibility, speed class, and storage capacity before making a decision.
