It seems freeBSD doesn't have lspci and I have no idea what's the equivalent. I do connect the usb drive via a usb2 pci card. When I plugin, I got this dmesg: uhub2: VIA UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub2: 2 ports with 2 removable, self powered ehci0: <VIA VT6202 USB 2.0 controller> mem 0xf4008400-0xf40084ff irq 9 at device 15.2 on pci0 ehci0: [GIANT-LOCKED] usb3: EHCI version 1.0 usb3: companion controllers, 2 ports each: usb1 usb2 usb3: <VIA VT6202 USB 2.0 controller> on ehci0 usb3: USB revision 2.0 uhub3: VIA EHCI root hub, class 9/0, rev 2.00/1.00, addr 1 uhub3: 4 ports with 4 removable, self powered ... da0 at umass-sim0 bus 0 target 0 lun 0 da0: <DMI External 1.12> Fixed Direct Access SCSI-0 device da0: 40.000MB/s transfers da0: 476940MB (976773168 512 byte sectors: 255H 63S/T 60801C) Looks right to me. > Rsync will only copy things that have changed, whereas SMB will copy the > whole file. > > Doug > Thanks for point it out. Looks like rsyncd will be a good choice. I will do another test run with rsyncd method and see if that can help. Any suggestion on how to find the speed limit step? How to determine how fast the data transfer to USB drive? In Vista, I can monitor network, harddrive, memory usage in real time. Does unix have something similar? Thanks!
