xD cards: is there a need for speed?

Do all xD-Picture Cards have the same read/write speed? I have seen the CNET article on SD and CompactFlash card speeds, but what about xD?

in our "Digital camera memory-card selector
" article because you don't really have many choices for that format. Not only is it the proprietary brainchild of Toshiba, Olympus, and Fujifilm, but it comes in only one write speed for capacities of 64MB and greater: 3MB per second (120X). Last February, the three companies announced a new generation of xD cards, dubbed Type M
for multi-level cell.
Though Type M cards will support higher capacities--the latest ones max out at 1GB, but the technology reportedly can go as high as at least 8GB--they're not compatible with some older cameras. However, the Type M cards are the same speed as the older version, and Fujifilm's U.K. site
warns that in some cases they may be even slower than their predecessors.
