You should be able to saturate a 100mbit link with anything made in the last 5 years. The slowest machine I have it a P6/200 with FreeBSD 4.1 and this disk: ad0: 3067MB <QUANTUM FIREBALL_TM3200A> [6232/16/63] at ata0-master using WDMA2 , which does 7MB/sec raw, can feed a NFS client doing a file read at 5MB/sec. -- Dan Nelson dnelson@allantgroup.com
