On a normal system, random access time will have a much bigger effect on performance than raw throughput. Although you can transfer 800K sequentially to or from the outer cylinders on a modern drive in 20ms, it's going to take just as long to transfer a single 4K block from an arbitrary disk location because of seek time and rotational latency. So, you'd be better off running a file system on each spindle and spreading your data out accross those file systems than striping for one big file system.
