My drive shows up as UDMA133 also. What I did notice is that my WD Raptor was slightly outperformed a few times on UFS2 by my actual ATA-100 Western Digital drive. This seems somewhat bad as the Raptor costs a hell of a lot more and one would hope that it would pound the ATA-100 drive pretty thoroughly. Even the CPU overheads on both drives were about the same. Maybe its=20 that 8MB caching :). I haven't found a good reason yet. Soeren, do you actually have SATA drives to test with or do you just=20 have SATA adapters with SATA->PATA dongles? Do you need more hardware to run some benchmarks yourself? [I don't know that I can afford to buy you a SATA disk but I wonder anyway :)] Dave > -S=F8ren > _______________________________________________ > freebsd-current@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-current > To unsubscribe, send any mail to=20 > "freebsd-current-unsubscribe@freebsd.org"
