Best SD cards for Raspberry Pi projects and small AI experiments

[WildManSteve40]

A lot of Raspberry Pi stability problems get blamed on the board or the operating system when the real issue is the card. For a Pi running logs, Docker containers, small AI tests, Home Assistant, or a little Python project, I would rather use a card with proven random performance than the cheapest large card on the page. The SanDisk 128GB Extreme PRO SDXC Card is a strong pick when you want fast transfers and a full size SD format, while the SanDisk Extreme PRO 128GB SDXC UHS-I Card is still a known option for camera and maker use. If the build is based around a Raspberry Pi 5, the Raspberry Pi 5 8GB gives you enough headroom to make the storage choice matter. I would avoid unknown brand cards for anything that writes constantly because the first failure usually happens after you trust the setup.

I have had cheap cards corrupt Pi installs more than once, so I agree that card quality matters more than people think.

For read mostly projects I will risk cheaper cards, but anything logging data every day gets a better card now.

The Pi 5 has made storage bottlenecks more obvious to me. It feels wrong putting a bargain bin card in it.

I still prefer moving serious Pi projects to an SSD, but a good SD card is fine for testing and lighter jobs.
