Slow file transfer over Gigabit

[imagoon]

Once you've replaced the network cables, you're not going to see any significant improvement because of the poor write speeds on your disk array. Not to say that there wasn't a network cable problem there, but it is not the only problem.

I'm not very familiar with highpoint products, but you should check out if there is a management software for the RAID controller. Check to see if there are any problems reported from any of the drives, check write cache settings, etc. You might also check windows event viewer and see if it is throwing any errors accessing the RAID disks.

The card he lists has a max 4k strip write speed of 150MBps and hitting 450MBps using a 16K stripe. Those cards are by far not "cheap crap consumer" level. Not "ultrahigh level server" but decent over all.

FYI. Auto speed/duplex has nothing to do with the cable being bad. This a common misunderstanding.

You can have two wires correct and both sides will agree to do 1000/full.

So here an interesting twist. I copied a file from another gigabit computer on the network and it came across very fast:

Originally, I was copying the 35 gig file from the client (laptop) to the server, so the slow write speed or laptop settings may be the issue that I will need to look at next.

You can also use Crystaldiskmark on a network share for a very rough look at how things are going.

They are the new 4 KB sector drives. You say you are running Server 2008, which IIRC does not support that.

Server 2008=Vista=Support for 4K sectors
