Version of Vista SP1 If I read the article correctly, it takes
348 seconds to transfer 1.9GB of data. That amounts to 5.6
MB/sec copyspeed, or about 11.2 MB/s transfer speed on the disk
(read + write). A simple, $50 SATA-II disk is able to sustain
50MB/s transfers, read or write, and quality hard disks even
more. What is happening with the remaining bandwidth? There is
some seek overhead, directory updates, etc but nothing that
would slow it down. Also, 11MB/s is hardly a big strain for main
memory, cache or PCI bus bandwidth, so it should not affect
responsiveness at all. Somebody mentioned lack of rigorous
benchmarking because no variance was measured. In this case, it
seems many times too slow compared to the physical limit of the
disk, so something is fun
