But 75k IOPS is a bit too much :) I've been doing some benchmarking using sysutils/fio recently. It seems that for my desktop SATA disk (a Samsung F3) around 28-30k iops is about the maximum, seen both on Windows 7 (NTFS) and FreeBSD (ZFS). FreeBSD is much more bursty compared to Windows, getting 80k iops and 210MB/s for a few seconds followed by several of 0. -- Bruce Cran _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "freebsd-performance-unsubscr...@freebsd.org"
