•Recommended capacity : 16GB to 256GB (MLC type)

It is VERY important when using micro SD cards for recording, that the cards are rated for heavier usage.

All flash memory has a finite number of write cycles. Meaning that unlike a spinning magnetic hard drive. 

Most off the shelf micro SD cards that can be bought online or from a local retailer will be consumer grade flash memory with a rough max number of writes to a cell of about 3,000 to 5,000 writes, before permanent failure will occur in each cell.

Below are some estimations on write cycles.

Triple Level Cell - Consumer grade flash:

3,000 to 5,000 write cycles maximum

Multi Level Cell - MLC - Is middle range flash memory, used in a number of commercial applications:

8,000 to 10,000 write cycles maximum

SLC - Single Level Cell - is high level flash memory. Normally used in SSD's but is available for micro SD cards.

90,000 to 100,000 write cycles maximum.
