It's the safe version of RAID 0.
On a real controller, yes performance can actually best RAID0. Of course four disks are required and the 50% overhead is hard to swallow. (as is with RAID1).
True RAID10 is what you want but that only exists in the SCSI world. A few SATA controllers may do it (LSi) however the firmware implication is unknown unless they really support this like their SCSI stuff does.
Getting back to topic at fist: 16MB cache may improve performance but honestly one is not going to feel it unless you're running SiSoft every day. RAID0 is rather task specific too. Any current gen ATA disk is going to be plenty fast for most desktop use. If you have a specific task then other options are available that are geared towards that use to improve storage performance.
