SD cards

Are SD cards reliable?

Episode 1037

Rolf from Barstow, CA

Rolf likes that Windows tablets have SD card slots to access more memory. Leo says that is a bonus, but it's important to understand that flash memory has a limited number of writes and can fail. So he should be sure to make a backup of the data he puts on them. He'll be able to get a few years out of them, though.

What microSD card should I get for my cell phone? (Part 1)

Episode 1034

Carla from Irvine, CA

Carla is looking for a good microSD for her Samsung Galaxy S3, but she keeps hearing about them crashing. Leo says that microSD cards can crash like anything else. Sandisk is his brand of choice. What class should she get? Leo says class 4 or better is fine, but she shouldn't spend a lot of money on class 10 cards because a cellphone can't really use that speed. Since they can crash, it's vital for her to back up her images and videos as often as she can.
