Hi Julien,<br><br>if you only have one Gigabit Ethernet then you can do a 128 megabytes/second transfer at max. And this is less than four 15k scsi disks can handle. So, at a worst case scenario you would have better speed if you had to totally re-sync two scsi disks.
<br><br>But usually you will probably be operation bellow that 128 MB/sec limit, so your answer depends on if you have another use for this third NIC or not.<br><br>Best regards,<br>Daniel Colchete<br><br><div><span class="gmail_quote">
