On paper, this SanDisk Extreme microSDHC 32GB UHS-I A1 V30 is very close to the Kingston microSDHC UHS-I U3 32GB, although it claims slightly lower write speeds (60MB/s versus 80MB/s). However, it does not hesitate to proudly wear the name "V30" which, theoretically, guarantees a write rate in video of 30 MB/s continuously.

PERFORMANCE:
Theoretical measurements were made using CrystalDiskMark 3.0.4. Practical steps for writing and reading large files were done using a 29 GB RAMDisk. We used a Lexar Professionnal Workflow USB 3.0 card reader. Theoretical results are obtained on CrystalDiskMark. This is the reduced average of 5 consecutive tests.

A priori at a disadvantage on paper compared to Kingston microSDHC UHS-I U3 32GB, this SanDisk Extreme microSDHC 32GB UHS-I A1 V30 is however equal game in practice. It will therefore easily handle the burden of a recording in 4K / UHD and will be perfectly in its element in a 360 ° action-cam. Count a little less than six minutes to completely empty the card.
