SanDisk 32 GB microSDHC Flash Memory Card SDSDQM-032G, for use in 8-Inch Vizio Tablet VTAB1008. Benchmark results, however, shows that the class-4 Sandisk card is actually faster - most of the time.
Has been used in two sets of benchmark programs. One is called "Flash Memory Toolkit v2.0 ', which measure the random read / write speeds between 1MB and 15MB file. The other is called 'H2testw v1.4', which measures the speed of read / write sequential use 1GB file. Here are the results of two sets of benchmark programs:
- For smaller files (1-5MB), then Sandisk class-4 card provides write speeds of stunning 15-17MB / s,
- For larger files (10-15MB), then the speed Sandisk 8mb / s for writing
- For large files (1GB), Sandisk dropped to 5.5MB / s
- Speed reading is high, which is about 18MB / S (this figure may be limited by the maximum speed card reader)

What shows up is that: When used in a typical digital camera (with 3-5MB file size), 'class-4 "card is SanDisk at least twice as fast as the others.

For a card that will be marketed as a 'class-10', should maintain the write speed of 10MB MINIMUM / s.Kartu Sandisk, on the other hand, beyond the needs of 'class-4' by a large margin.

The capacity of this card, as reported by the computer on my computer, only 29.7GB. Note that this is actually normal, because the computer defines a person's Giga 'as '2 to the 30th power', which is 7.4% greater than 1 billion. So 29.7GB comes to nearly 32 billion bytes, which is 32GB according to the marketing people''.
