|Canon IXUS 90 IS Storage capacity
10 Megapixel and JPEG format storage in the lowest possible compression deliver a file size of approximately 4.3MB. If we take around 200 pictures, 1GB of storage capacity is the least we need. And if you plan to run wild with the video capturing function, and want to capture a 30 minute video in the highest quality, you have to consider purchasing 8GB of storage. I’d advice you to purchase sufficient storage capacity which should not be a problem with today’s prices. A so-called SDHC memory card with a minimum storage capacity of 4GB is my suggestion.
Considering a 1GB storage capacity:

|SD & SDHC memory cards
The SHDC card is slowly catching up with the SD memory card. In fact it is the same format but technically upgraded to enable surpassing the 2GB boundary. A storage capacity of 4GB is the minimum as far as I am concerned and that gives me enough reason to use the SDHC memory card as a standard storage medium. Also for the Canon IXUS 90 IS camera. If you don’t need this much capacity, you can go for the SD card. The SanDisk Ultra II Plus SD memory card is a very convenient card. It has the size of an SD card but with an additional unique feature: you can remove the card from the camera and literally break it in two which frees a USB interface. This enables inserting the card immediately in a free USB port and get access to the stored pictures or videos.
Speediness of memory cards and card readers
SD memory cards are available in various speeds. The advantage of a faster memory card is rapid data transfer providing the computer and the device reading the card are equipped with a fast USB 2.0 Hi-Speed connection. Or you can choose to purchase a card reader. This handy device needs to be connected to the USB port and is capable of reading a card and writing to it rapidly. The computer will recognize the device as an external hard drive. Additionally you will also save energy.
NB-5 Lithium Ion battery
Canon is a faithful user of the NB-5L Lithium-Ion battery and we can consider that to be an advantage. If you swap from an old model IXUS to a newer one, chances are high that you can keep on using the same battery. The NB-5L battery has a capacity of 3.7V 1120mAh. The battery needs approximately 2 hours to fully charge and serves for more than 300 pictures. (Room temperature, change of wide angle and telephoto lens every 30 seconds, using flash every other picture and deactivating the camera each time after capturing 10 pictures. Camera stays deactivated for a while. After that camera is activated again and test procedure is repeated.) If you expect to take more pictures or if you frequently play back the captured images or videos, a second battery might be an option.
