We have a Snap Server 4100 system that had failing HDs and wasn't really being used anymore. (SnapOS 3.4.803) We decided to try and get some more 'life' out of the system, and to try and replaced the HDs in it.

We put in 4 identical brand-new Seagate 120GB 7200rpm drives; and formatted them into a RAID 5.

After it finished building, (I left it overnight, but the log shows it only took a couple of hours) we started backing up some machine images to it; but the transfer speeds were PAINFULLY slow! In windows going to the share, with no other users connected to the snap server, it was only copying the single large image file at about 20% of the 100Mbps link as shown in the windows task manager--about 2.5MBps! If 2 people used it at once the rate dropped down to a mere 6% average (750KBps!)

That seems pretty low for the 'max speed' of this sort of device?

I tried an FTP test, and it is MUCH WORSE! FTP to the 4100 over 100Mbps connection only transfers at 400KBps-500KBps! I can't get an FTP transfer faster than 500KBps! That's only 4Mbps...my home Internet connection is faster than that!

Also, watching the transfers in Task Manager, the connection level 'drops' every 5 seconds or so to almost nothing, and then starts again a second later.

Thinking it might be a network issue, I checked the switch, but there are no errors shown on it. I also swapped the network cables. The same performance was seen from multiple Windows machines to this snap Device. The other windows servers on this switch test at normal expected speeds (they're Gigabit NICs and transfer at 90% of the 100Mbps connection on my computer); and they have similar spec'd drives (3 80GB ATA drives in a RAID 5 for example).

I remember that this snap server used to be 'slow' before but not THIS slow!

Is there any Network settings or things to check on the Snap itself? After replacing the drives, the system retained all it's previous 'settings' (IP address, shares, name, etc), although obviously all data was gone. Should I have reset it to Factory Defaults? What else should I look at? Anyone else have a working 4100? What kind of speeds do you get?
