With laptop price under $500, I don't think cost is a concern.
As for data transfer rate, I have my music stored in NAS and retrieve them wireless using 802.11g and still fast enough. In fact, I can upload/download music files simultaneously w/o issue.
Storing files in NAS has the added benefit of automatic backup. Buffalo NAS has RAID and I prefer having redundancy than larger space, I don't have to worry about HD crashing. Also, I can put the noise making HD away from my listening room.
