I see two possible issues. Most likely, your issue is caused by using hard disks that are Advanced Format drives. AF drives are not inherently compatible with the X310 because it is running the original version of Windows Home Server. That version was built ontop of Windows Server 2003. Some drives have jumper settings to adapt AF drives to work on XP, Server 2003 and WHS systems. I'd look into that. Also, it could be your Symantec product. To check, try temporarily disabling it on your connected workstations and see if slow downs go away.
