wily, <never above 5MB/sec.... What is limiting me here?> Windows is limiting. WindowsXX has typical data transfer requests in chunks of 4kB only. To get good transfer rates out of a drive, you need requests of 64kB at least. 25MB/s is a contiguous transfer rate from outer cylinders of freshly defragmented drive when running in bus-mastering mode under DOS. You should not confuse this rate with numbers sometimes reported from some hand-crafted HD benchmarks when running under Windows. With WinXX disk cache you may easily get bogus 100 or 160 MB/s, which is apparently non-sustainable, and where 99% of data comes form the system memory (disk cache). Take care, - Ali
