eSata because network too slow
Hi Everyone i am new to this product. I have a Ready Nas 4200, i have 4 3tb drives on raid 5. The problems i am having is getting my 6tb of files from my MacPro 2010 over the network. I am runing...

Can i use the esata to transfer files ?
Not from the Mac Pro. You can connect an external disk via esata, but not a computer. Computers can only access the NAS via the network.

Are you confusing megabytes and megabits? ~116 MB/sec is the ceiling for gigabit ethernet.
basically Mbps or like 20 megabytes
i only have in one drive now and i am getting 258Mbps. when i use two drives i get 119Mbps

You mean you destroyed the RAID array and built a new one?
-what firmware is the NAS running?
-was the RAID volume still syncing when you ran your tests?
-what are you using to measure the speed?
-Firmware 6.5.0
-No it was not syncing
-i am using iStat for mac

Mbps is Megabits per second.
MBps is MegaBytes per second.
It makes a huge difference onto the values and their signification!
For example, the practical limit is around 120MBps on a 1000Mbps network (1Gbps).
Mb/s istat uses. I am sending over a 7gig video file, its taking like 15 min and shows 68Mb/s

The math checks out (7*8*1024*1024*1024/900 is 67 mbits).
Reasons for slow speeds:
-some service or background process running on the NAS
-internet security or AV software running on the client
-packet loss/congestion on the network
-packet fragmentation on the network
-mixed speed networks with no flow control
-failing disks on the NAS
-Can you confirm that all links on the path are gigabit? (I imagine you already have, but am just confirming).
-are you using jumbo frames on the client
-what services are running on the NAS
-have you looked at the disk health?
-can you check both read and write speeds?
