Find the Cheapest SD Cards Per GB in 2026
Looking for the best SD card deals? BuyPerUnit compares 696+ SD cards and microSD cards ranked by price per gigabyte — so you can find the most storage for your money.
Right now, the cheapest SD card storage starts at just $0.000/GB, while the average across all cards is $38.475/GB. Whether you need storage for your camera, drone, Nintendo Switch, or phone, we help you find the best value.
SD Card Buying Guide: Get the Best Value
1. Bigger Cards = Lower $/GB
A 256GB card at $25 ($0.098/GB) beats a 64GB card at $12 ($0.188/GB) in value. If you can afford more capacity upfront, you'll save long-term.
2. Match Speed to Your Device
4K video needs U3/V30 speed. 1080p or photos need U1/Class 10. Don't overpay for speed your device can't use.
3. microSD + Adapter
microSD cards with adapters work in both slots. They're usually the same price and offer more flexibility than full-size SD cards.
4. Stick to Known Brands
SanDisk, Samsung, and Lexar are reliable. Avoid no-name cards with suspiciously low prices — they often have fake capacity ratings.
microSD vs SD Card: Which Should You Buy?
| Type | Typical $/GB | Max Capacity | Best For |
|---|---|---|---|
| microSD | $0.05-0.15 | 1TB | Phones, Switch, GoPro, drones |
| SD Card | $0.05-0.20 | 1TB | DSLR cameras, camcorders |
