What is the best SD card?

The "best" SD card depends entirely on what you are using it for —whether it's high-speed 4K/8K video recording, fast burst photography, or just general everyday use in a Nintendo Switch or dashcam.

The top-performing SD cards categorized by use case include:

1. Best Overall / Professional Video & Burst Photography: SanDisk Extreme PRO UHS-II V90 SDXC Go to product viewer dialog for this item.

To help narrow down the exact card you need, let me know:

• What device are you putting the card into (camera model, drone, switch, etc.)?
• What resolution/format are you shooting or storing (4K video, RAW photos, casual snaps)?

If you mean a full-size SD card for a camera, my best all-around pick is:

• SanDisk 256GB Extreme PRO SD UHS-I - $91.95 (newegg.com)

My picks

• Best overall: SanDisk Extreme PRO 256GB UHS-I — fast, V30/U3, excellent for 4K video and burst photography.
• Best value: Samsung PRO Plus 256GB — excellent performance for the money; current comparisons put it among the strongest value choices.
• For professional 6K/8K video: Go V60 or V90/UHS-II rather than a normal V30 card.
• If you need microSD: SanDisk Extreme or Samsung PRO Plus are excellent general-purpose choices; V30 is the sweet spot for most 4K devices.

For most people, I'd buy 256GB V30/U3. It's a much better balance than paying a premium for 512GB/1TB unless you regularly shoot lots of video.

If you tell me what device you're putting it in (camera/GoPro/phone/Switch/Steam Deck/etc.), I can give you the exact best card and capacity.

If you mean a full-size SD card for a camera, my best all-around pick right now is the SanDisk Extreme PRO UHS-II V60. It offers V60 sustained write performance, up to 300 MB/s read speeds, and is rated for demanding 4K/6K video and burst photography.

• SanDisk Extreme PRO 256GB UHS-II V60 - $249.99 (Best Buy)

My picks by use

• Best overall: SanDisk Extreme PRO UHS-II V60 — excellent for serious photography and 4K/6K video.
• Best value:

— V60, up to 280 MB/s read and 205 MB/s write, currently around $200 in the results I found.

• Best budget/most cameras: SanDisk Extreme PRO UHS-I V30 — plenty for most 4K cameras and substantially cheaper than UHS-II.
• For extremely demanding 8K/RAW: look for V90 rather than V60; the camera must support it.

If you tell me what device you're using (camera/phone/GoPro/Switch/drone) and how much storage you want (128GB, 256GB, 512GB, 1TB), I can tell you the exact card I'd buy.

The "best" SD card depends heavily on what you are using it for (photography, 4K/8K video, action cameras, or a Nintendo Switch) and whether your device supports high-speed UHS-I or UHS-II formats. [1][2]

The top-performing SD and microSD cards on the market are categorized below by their strengths:

1. Best Overall for Cameras (UHS-I)

Add to list This is the gold standard for everyday and enthusiast photographers. It offers great write speeds (up to 90MB/s) and read speeds (up to 200MB/s on compatible readers), easily handling raw burst photography and solid 4K video recording. It’s reliable, weather-resistant, and widely compatible with almost all mainstream cameras.

2. Best for Professional Speed & Video (UHS-II / V90)

Add to list If you shoot high-bitrate 4K/8K video or rapid-fire RAW bursts on a high-end professional camera, you want a V90 UHS-II card. The Sony Tough series features a solid molded resin build that lacks the fragile plastic ribs and write-protect switches of normal cards, making it 18x stronger and completely waterproof/dustproof (IP68) alongside blazing read/write speeds (~300MB/s).[1]

Add to list A slightly more affordable alternative to Sony's Tough line for pure high-speed transfer and buffer clearing, highly rated by professionals.

3. Best Value & Performance

4. Best for Drones, Action, and Dash Cams (MicroSD)

Add to list Comes with an SD adapter and dominates the drone and action camera market due to its temperature, shock, and water resistance combined with high write speeds.

Add to list Specifically built for continuous 24/7 write cycles. Choose these if you are buying a card for a security setup or a car dash cam where regular cards would quickly wear out.

If you let me know what device you are putting the card into (e.g., a specific camera model, drone, or Nintendo Switch) and your preferred capacity , I can recommend the exact card and size you need.

If you mean a full-size SD card for a camera, my best all-around pick right now is:

• SanDisk Extreme PRO UHS-II V90 - $207.99 (Best Buy)

One important catch: the "best" SD card depends heavily on your device. A UHS-II card in a UHS-I-only camera won't give you UHS-II speeds.

If you tell me what camera/device you have (e.g. Sony A7 IV, Canon R6 II, GoPro, Nintendo Switch, Steam Deck, etc.) and your preferred capacity/budget, I can tell you the exact SD card I'd buy.

Top SD Card Options

How to Choose

• Check your camera: Older or basic cameras only need a standard UHS-I card (V30 class). High-end mirrorless and cinema cameras need faster UHS-II cards (V60 or V90 classes). [1][2][3]
• Look at the V-rating: The video speed class (like V30 or V90) tells you the minimum sustained writing speed. Buy V30 for standard 4K video or V90 if you record heavy 8K/high-bitrate files. [1][2][3]

If you share your camera model and what you plan to shoot (photos or video) , I can recommend the exact card speed and size you need.

If you mean a regular full-size SD card, my best all-around pick right now is the SanDisk Extreme PRO SDXC UHS-I V30, especially 256GB. It offers up to 200–250 MB/s read speeds and is rated U3/V30, making it a strong choice for photography and 4K video.
