October 21, 201015 yr I'm moving all my data to my new UnRaid box and i was wondering if the write speed that im getting is normal, super fast or super slow. I was checking in UnMenu, under "MyMain" tab in performance view. There says that my Write I/O is 21,2 MB/s atm. Sometimes goes low as 9MB/s or 6MB/s and sometimes goes up to 24MB/s The file that im moving now (bunch of folders) is 470 gb and looks like is going to take 14 hours. And i have a lot of data to move after that. Another question. Should I move the folders 1 by one or just a bunch of them all together? Would make any difference in the write speed? Btw im over 100mb network.
October 21, 201015 yr Quite normal for a 100Mb/s network. I'm surprised you are seeing anything much above 12MB/s with it. Your PC will only send one file at a time, so you might as well queue up a bunch of them. You'll do a lot better if you can get a 1000Mb/s connection. (I realize the PC might not have the capability, so in that case, just be patient) With a 1000Mb/s connection many get between 25 and 35 MB/s transfer speed. Joe L.
October 22, 201015 yr Author Im going to the states again in a few weeks and i'll be getting a 1000 switch. (i live in Chile) and it was pretty interesting bring the Server as my luggage last week LOL.
October 22, 201015 yr Not sure where the files are coming from. If they are coming from a storage (i.e. non-OS) drive in one of your pc's or perhaps a USB enclosure it is possible to install the drive in your server and mount it in unRAID. Search the forums for SNAP or midnight commander (MC). This would allow you to eliminate the 100 mbps LAN bottleneck while transfering files. Might not be worth the effort though if you're only moving over ~0.5 TB. Also, this does not apply to your current situation, but once you have a 1000mbps connection you can also remove the parity drive from the array when you initially transfer files onto your server. You would see transfer speeds of 60-70MB/s with the parity drive removed as compared to 25-35MB/s with it installed. Once the transfer is complete then add the parity drive back in and calculate parity. This is what I did when I first copied all my info onto my server. Once I had a good parity calculation then I deleted all the files from their previous location.
October 22, 201015 yr Odd, when I had a 100Mbps network I consistantly saw a 11MBps flat line transfer speed. It's pretty much impossible to be transfering at 21Mbps over a 100Mbps network. It's hard to believe you're getting this transfer speed unless you have the data device connected right to the server and you are avoiding the network. Why don't you tell us where the data is coming from. Peter

Why don't you tell us where the data is coming from. Peter He described the "performance" tab on unMENU. It shows write performance to the disks, after the data is already being transferred on the LAN to the buffer cache. It is easy to see why it was jumping all over the place, depending on the data transferred and the buffer-cache in memory being flushed to the disks. I suspect the network performance was 10-11 MB/s as usual on a 100Mb/s LAN connection. Joe L.
