I am getting about 12 MB/s for sequential reads single threaded per 
disk. The disks are 18GB, 7200 rpm, ultra fast/wide scsi disks. I am 
really not sure about the cache.

So what is the consensus now? Let's just stick to RAID 0 - should I see 
more when going multithreaded or should I not be worried that the 
transfer rates are dropping off? Note that the rates drop off even if I 
am only running a 2 disk RAID  0 i.e. my bus is not being maxed out then.

Cheers, Vlad.
