SanDisk 400GB MicroSD Card: Use your phone like a portable drive

SanDisk 400GB Class 10 MicroSD Card

Get It For: Rs 21,499

This 400GB microSD card is the highest capacity micro SD card currently available. It’s meant for niche users who want to keep or record a lot of 4k videos or use their phone as their portable drive for all personal data.


Since there are not a lot of smartphones supporting 400GB cards, SanDisk also includes a microSD to SD card adapter — this way you can use it with any laptop also. We used the card with an Asus Zenfone Max Pro M1 and it worked flawlessly.


Out of the 400GB, we had access to 387GB of storage on the card.

In AndroBench, the card scored a read speed of 82.39 MB/s while the write speed was 57.32 MB/s.

SanDisk claims a read speed of up to 100 MB/s, so a speed of 82.3 MB/s is impressive in our opinion.
