How do I test disk performance in Freebsd60 ?
I use FreeBSD60 on Dell1600 SC ( 2gbyte Ram 4 CPU ) amr0: LSILogic MegaRAID 1.51 mem 0xfcc0-0xfcc0 irq 21 at device 2.0 on pci2 amr0: LSILogic PERC 4/SC Firmware 351X, BIOS 1.10, 64MB RAM I have 3 scsi disks that each about 70 Gbyte based RAID5. That is Total capacity nearly 140 Gbyte. I want to test disk / raid card. I tried below command 10 times while I 'm root date dd if=/dev/zero of=deleteme.now bs=64k count=300 rm deleteme.now date 1 - 19660800 bytes transferred in 3.420916 secs (5747232 bytes/sec) 2 - 19660800 bytes transferred in 3.318186 secs (5925165 bytes/sec) 3 - 19660800 bytes transferred in 1.325308 secs (14834893 bytes/sec) 4 - 19660800 bytes transferred in 1.475633 secs (13323637 bytes/sec) 5 - 19660800 bytes transferred in 1.458992 secs (13475605 bytes/sec) 6 - 19660800 bytes transferred in 1.373914 secs (14310066 bytes/sec) 7 - 19660800 bytes transferred in 1.597467 secs (19307485 bytes/sec) 8 - 19660800 bytes transferred in 1.308806 secs (15021937 bytes/sec) 9 - 19660800 bytes transferred in 1.324031 secs (14849201 bytes/sec) 10- 19660800 bytes transferred in 1.438717 secs (13665510 bytes/sec) As you see the values of bytes/sec is not stable very changeable. I wonder Do disks or the raid card work properly ?

I want to test disk / cd /usr/ports ; make search info=performance should give you some tools (bonnie, from memory) raid card. ... other than setup raid, yank the cable in one/several of the drives and see what happens?
