1What's the difference between SD, microSD, and CompactFlash cards?
SD cards are the standard size for cameras and devices, microSD is the tiny version for phones and drones, and CompactFlash is older technology rarely used now. Unless you have an older camera, you'll want either SD or microSD depending on your device.
2How much storage capacity do I actually need?
For photos, 64GB works for most people shooting in standard formats; for 4K video, aim for 128GB or higher since footage eats space quickly. If you're shooting all day or recording long videos, go larger to avoid swapping cards mid-shoot.
3Does read/write speed matter, and what numbers should I look for?
Read speed affects how fast you transfer files to your computer, while write speed matters for capturing video without dropping frames. For 4K video, look for cards rated V30 or V60 minimum; for photos and regular use, V10 is usually fine.
4What's the difference between UHS-II and UHS-III cards?
UHS-III is faster than UHS-II, but only if your device supports it—check your camera or device specs first. If your device only supports UHS-II, buying the pricier UHS-III won't give you any real benefit.
5Is it worth buying from major brands versus cheaper alternatives?
Major brands like SanDisk and Kingston have better reliability and warranty support, which matters since card failure means losing your footage. Cheaper cards occasionally work fine, but the risk isn't worth it when your irreplaceable moments are at stake.
