It is most popular memory card for digital cameras.
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.
| Class 2
| Class 4
| Class 6
| Class 10
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.
