This could be a difficult question, so I hope I have allocated enough points for it. I am creating a media storage server by using a NAS storage device. Specifically, I have a LaCie Ethernet Disk Mini 1TB NAS drive with Gigagibit port. We are sampling a single DVD ripped with AnyDVD. This particular Video TS folder is 7700MB. I have used two different laptops, a Toshiba X205-SLi and a Gateway TA6 Tablet PC. Both PC's have a 10/100 ethernet port. I am not positive of the HD speeds. I am pretty sure they Gateway is a 5400 RPM, but I believe the Toshiba has 7200RPM drives. I have now attached to a basic Linksys router, using its 4 port 10/100 switch. Nothing else is connected except 1 PC and the NAS drive. I have also tried it on our Gigabit backbone plugging directly into a Netgear 24 port Gigabit switch. I don't have the model off hand, but all ports are gigabit. This network does have some traffic on it, but not to the point to even come close to maximizing the traffic.
I am accessing the drive by typing the drive through Internet Explorer, \\192.168.0.X. From there I either drag the Video TS folder or copy/paste it into the network drive.
In any case the results are the same. It is taking roughly 8 hours on either PC. Looking at C-net's review of this piece, their test system transfered a 5GB test file in about 19m and a 10GB file in 40m.
What could be causing this huge discrepancy? I know there are a lot of factors involved - HD speeds, network speeds, NAS HD speeds, etc.
