Maplestory and a SSD - help

An SSD is not going to help much at all. Maplestory's data is compressed. The bottleneck you get in load time is actually the uncompression of files and not the reading of them. The processor controls that speed. The hiccups you get when people show up in your map are due to maple uncompressing the proper sprites/animations from the WZ files. First it reads it from disk, then it uncompresses it to memory. The disk read is the shortest part of that operation.
