writes *unless* you are creating an ISO image on your disk. In my opinion it is much more important to optimize for the more common, concurrent read case, than it is for the sequential write case with intermittent reads.
You're missing the point. The only reason the reads are intermittent is that the application can't proceed until the read is done and the read is being starved by writes. If the read was serviced immediately, the next read could get scheduled quickly and they wouldn't be intermittant.
