SanDisk 256GB (A1) MicroSD
If you want nearly the biggest microSD card money can buy, get the San Disk 256GB A1 card. Yes, SanDisk recently released a 400GB card but it's way too expensive.
"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."
The biggest difference is with load times on phones. Launching apps or games is noticeably faster. It sounds like typical "press marketing" but it's true this time. Basically ensuring great performance and tons of space. This is the best price/performance/storage option available. I'll use this while I want for the 400GB cards to come down in price.
A regular 256GB Ultra Class 10 can be found for $149.
