New SanDisk SDHC card

It is most popular memory card for digital cameras.
SD card

Based on the capacity, there is different type of SD card.


SDSC (SD): 1 MB to 2 GB,   some 4 GB available.
SDHC: 4 GB to 32 GB
SDXC: ≥32 GB to 2 TB

I bought a San Disk Ultra SDHC cards pack. 2 X 16GB in one pack. with three color labels.

It is class 10.


Class is another important specification. It tells the speed to read, write, or transfer the data.

SDHC Speed Class 2.svg Class 2 MB/sec
SDHC Speed Class 4.svg Class 4 4 MB/sec
SDHC Speed Class 6.svg Class 6 6 MB/sec
SDHC Speed Class 10.svg Class 10 10 MB/sec

The bigger the class number, the faster.

To use the card in the different scenario.

  • Class 2 for SD video recording
  • Class 4 and 6 for high-definition video (HD) to Full HD video recording,
  • Class 10 for Full HD video recording and consecutive recording of HD stills

And also, to make sure the card you buy is campatiable with your device, say a CoolPix L22 digital camera. Go to the official site to find the list of Aproved SD cards for this product.

For this memory card pack I bought, open the pack completed, because the color labels are located on the upper portion.

It is about $20.00. 10 years warranty. 30MB/s read speed.
