M+ XD cards work on the same products as M cards, only they're faster.
XD memory cards let you store data -- mainly digital pictures, and then transfer it between devices. There were two primary XD card types: M and M +. The XD card is now obsolete.
History
XD cards reached the market in 2002. They were developed by Fujifilm and Olympus as a means to store audio and visual data in portable media. The drawback to the XD cards was that they only worked in Fujifilm and Olympus products, unlike the SD card, which has more universal compatibility.
Type M Cards
Type M cards hit the market in 2005. They could store up to 2 gigabytes (GB) of audio or visual data, weighed 2 grams and had a NAND Flash-type memory.
Type M + Cards
The XD Type M+ cards had one major difference over the type M cards -- they could transfer data up to 1.5 times faster than the type M cards. Since they were developed later (2008), they also were compatible on some modes that the type M card was not. Physically, they were identical to the type M cards.
