The router is only 10/100 but is only used for the internet.
Note that fast broadband (> 25Mbps) requires both a router and modem with gigabit WAN ports
The pc that I was using (Win XP Pro) only has a network card of 10/100 as does its switch it is plugged into. The laptop is Win 7 and has a 1G network card but I had it plugged into the same switch (10/100) as my pc so I could transfer the documents.
I would recommend replacing all 10/100 switches and cards with gigabit. The prices are so low these days it just isn't worth suffering with 10/100 anymore. You won't see 10x faster performance, but you should see from 2x to 5x faster transfer speeds, depending on what other bottlenecks there might be in the pipeline. Also note that two systems don't have to be plugged into the same switch in order to transfer files, they just have to be on the same LAN.
I think the write back cache is enabled by default??
The write-back cache is disabled by default under Intel chipset-based RAID. Scott.
