Haven't tried a microSD, using USB stick instead, but the mid/high-tier cards from SanDisk or Samsung should be a safe bet in terms of performance, reliability and durability.
The max AsiAir Plus supports up to 1TB cards,

Example models to consider: SanDisk Extreme or Ultra series, or Samsung Pro Plus or Evo Plus series should do the job.
