SanDisk Class A1 Micro-SD Card (256GB)
Back in 2017, SanDisk released an all-new Class "A1" build for mobile. This WILL make your phone faster. It's called the A1 specification. Instead of Class 1, UHS-1, or any of those other crazy markings on an SD chip -- look for "A1".
Essentially SanDisk's new 256GB A1 microSD card is way faster than anything prior, and guarantees to make our phones open apps and games quicker. Better performance throughout.
"A1 can manage random read input-output access per second (IOPS) of 1,500 and write IOPS of 500, so it can quickly open apps and process accompanying tasks, such as audio, graphics, saved profiles and in-app permissions."
It sounds like typical "press marketing" but this is real. The performance makes apps and games open a little faster, which makes a big difference day in and day out.
Last year these were $200, but now you can find it for around $85.
