The first benchmark I used was Marcel Weber's CliBench Mk III SMP v0.7.10.
I was rather surprised
to see Windows Me come out with the fastest maximum read and write times. Its
read maximum was as high as 32 megs per second, a good 25% faster than the
highest read rate under Windows 2000 Pro. In case you're wondering, the UDMA/33
controller is not a limiting factor here. I ran some tests with the PCI bus, and
thus the onboard UDMA/33 controllers, overclocked, and got similar results.
Still, clearly the drive comes close to the limit of the UDMA/33 interface.
Interestingly, the minimum numbers were higher under Windows 2000 Pro, and CPU
usage was far lower.
Next, I ran Intel's IOMeter under Windows 2000 (it won't run under 9x). The settings were sequential/random 50%/50%, read/write 75%/25%, 1MB access chunks with updates every second (which is why the first two rows have identical results). Each run was 15 minutes in length.
Here, FAT32 is a little faster than NTFS5. This
shouldn't come as much of a surprise, since NTFS has a lot of reliability and
management overhead that FAT32 doesn't.
