The H type of Olympus uses the DC main control in a fixed firing way to promote the speed. At this field Fuji and Olympus have separately choosed different technology to meet the speed requirement. The read-write speed is twice faster than normal type, and three times than M type. The normal reading rate is 4M/S and write-in rate 2.5M/S. And because of the low speed ( the most terrible disadvantage of MLC), it often makes troubles when recording videos.

However it runs into the trouble of incompatibility with some old Olympus and Fuji devices. M type is the MLC technology XD card developed in 2005. The normal reading rate is 5M/S and write-in rate 3M/S.

The earliest XD card is the so-called normal type. The different point is the different technology and chips, so that the speed is different, too. The sizes of these three kinds are the same. The common kinds of XD card in the market are these three kinds: normal type, M type, and H type. If there is need to delete a picture, it is suggested to delete it on the DC rather than on the computer. (2) When transmit pictures through a card reader, it is better to copy than to cut.

This will make the card cannot save pictures and drop dead halt. (1) Try not to format XD card through a card reader otherwise it will cause the format error of the card.

It also can be used as a storage medium of Compact Flash in DC. XD-picture card can not only be used at PC adaptor card and USB card reader, but also Compact Flash convert adaptor. It satisfies large amount of data write-in and has a lower consumption. And the read-write speed is faster ( reading rate is 5MB/S, and writing rate is 3MB/S). Fuji and Olympus have developed XD card with the largest capacity of 1GB in 2004. The common capacity of XD card is 512MB, 1G, and 2G. The theoretical maximum capacity can be 8GB. It is the lighter and smaller digital Flash Memory ay present. The size of it is 20*25*1.7mm, and the total volume is only 0.85 cubic centimeter. Compared to other Flash Memory, it has lots of advantages. XD-PICTURE CARD, XD card in short, which is taken from ' Extreme Digital', is a new kind of Flash Memory card. It can be used with various card readers and connected to PC. XD card has a super large capacity and great compatibility.

It becomes popular because of its mini size, light and convenient features. XD card, full name XD picture Card, is developed specially for saving digital pictures.
