Find the Cheapest SD Cards Per GB in 2026

Looking for the best SD card deals? BuyPerUnit compares 876+ 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 $2.199/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.

Frequently Asked Questions About SD Cards

What's the cheapest microSD card per GB right now?
The cheapest SD card storage per gigabyte is currently $0.0000/GB. Higher capacity cards (256GB+) typically offer the lowest price per gigabyte.
What SD card speed do I need for 4K video?
For 4K video recording, you need at least a U3 or V30 rated card. These can write at 30MB/s or faster, which is necessary for 4K bitrates. For 8K or high-bitrate 4K, look for V60 or V90 cards.
What size SD card do I need for Nintendo Switch?
Most Switch games are 5-15GB, with some up to 30GB. A 256GB card holds 15-40 games and offers the best value. 512GB or 1TB is overkill unless you have a huge digital library. Any U1/Class 10 card is fast enough for the Switch.
Are SanDisk and Samsung SD cards worth the premium?
SanDisk and Samsung have excellent reliability and warranties. For professional use (weddings, paid work), the peace of mind is worth it. For casual use, budget brands like Silicon Power or Lexar offer good value with solid reliability.
