They’re designed for everyday tasks like photos, apps, and video recording when used in compatible devices and handled with care. Dependability often comes down to choosing the right card for your device and use case.

• Match specs: Look for speed symbols (for example, Class 10 or U1) shown on this page and match them to your device’s requirements.
• Use properly: Always eject before removing, avoid filling to 100%, and keep cards away from extreme heat or moisture.
• Store safely: Use cases to protect contacts from dust and scratches.

Performance and lifespan can vary based on device settings and usage habits, so following these tips can help maintain reliability.

They’re removable flash storage you can use to add space for photos, videos, apps, and files on compatible phones, tablets, cameras, and laptops. This page includes different formats and capacities to fit a range of devices and needs.

• Formats you’ll see: SDHC, microSDHC, and microSDXC options are listed here.
• Capacities: You’ll find compact sizes like 32GB and larger options like 256GB and 512GB.
• Transfers: If your computer doesn’t have a slot, a USB card reader (including USB-C/USB options on this page) can help move files.

Always check your device’s manual to confirm supported card types and maximum capacity before buying.

Instead of focusing on names, compare by features that affect your day-to-day use.

• Capacity: Pick the space you need—from smaller sizes (e.g., 32GB) for casual use to larger options (e.g., 256GB or 512GB) for big media libraries.
• Speed class: Look for symbols on the card like Class 10 or U1 shown on this page; match them to your device’s recommendations for photos, burst shots, or video.
• Compatibility: Check whether your device supports SDHC, microSDHC, or microSDXC.
• Accessories: Consider whether you’ll use a card reader for transfers.

Your best pick depends on your device and workflow. Results can vary with file types and settings.

Formatting prepares the card for your device. It erases data, so back up first.

1. In a phone/tablet: Go to Settings > Storage (or similar), select the card, and choose Format. Use the option your device suggests.
2. On a Windows PC: Open File Explorer, right‑click the card, select Format, keep the default settings your system provides, and start the process.
3. On a Mac: Open Disk Utility, select the card, choose Erase, and use the format your device recommends.
4. In a camera: Insert the card and use the in‑camera menu to format.

After formatting, safely eject before removing the card. Results can vary by device and operating system.

It depends on what your device supports. This page includes microSDHC and microSDXC cards, and not all devices accept every format.

• Check compatibility: Your device manual or support page should list supported formats (microSDHC vs. microSDXC) and maximum capacity.
• Physical size: microSD cards are smaller than full‑size SD. Some devices accept microSD cards using an SD adapter; verify before use.
• Transfers: If your device can’t take a card directly, you can move files via a USB card reader.

Choosing a card that matches your device’s format and capacity guidelines helps avoid errors and keeps performance consistent.
