<div>Dear all-users:</div>
<div> I wanna test a block-level caching and prefetching algorithm upon DiskSim. Does Disk contain a single buffer?The cache in the internal disk is not the one. The test case is very simple. If disksim has one, Can I prohibit it to make sure no cache or prefetching effect except the one I use. Should I build one myself combining the current version or use the one in DiskSim?</div>

<div> Look forward to your help.</div>
<div> Thanks.</div>
