SDXC cards can hold 48GB – 2TB worth of pictures and video.

Other Vital Memory Card Information

For those of you who are thinking about getting memory card for the A490, you should realize that aside from storage capacities, memory cards also have different speed ratings. These speed ratings on the memory cards are there to show the speed at which data can be read or written directly to the card. SD and SDHC cards have speed ratings of 2, 4, 6 and 10. SDXC cards speed ratings go from Class 4, 6 and 10. SDXC cards also have another speed rating known as Ultra High Speed (UHS)

  • Class 2 – Minimum of 2 MB/s performance. (Slowest)
  • Class 4 – Minimum of 4 MB/s performance. (Average)
  • Class 6 – Minimum of 6 MB/s performance.  (Above Average)
  • Class 10 – Minimum of 10 MB/s performance. (Fastest)
  • UHS-1 (SDXC CARDS) – Speeds up to 104 MB/s.

Our speed class rating for the Canon A490 would be to get either a Class 4, 6 or 10. The best choice would be to go with a Class 10, as the prices are so cheap now. My experience with the slower cards has been nothing but frustration. When taking pictures on the high settings, the camera takes a while to write the data to the memory card. If I had owned a faster speed class card, I would not have to wait as long. The same can be said about transferring video and pictures from the camera to the computer. With a slower card, it can be a painstakingly slow process.

This is a cheaper option if the 32 GB is too expensive, but one thing that I am certain of is that you will be getting a quality product.

*Compatibility Issues

Now that you have identified the memory card that you want, if it is a SDHC or SDXC card, then you need to check your computer or laptop’s card reader. Many of the older computers/laptops have SD card readers and as such they will not be able to read the SDHC or SDXC card formats. If you look and see it can only read SD, then you need to get a card reader that can read SDHC and SDXC cards. The good thing is that these products are not that expensive. If you are looking at getting one, you can get one here.
