Zudnic Posted October 20, 2020 Share Posted October 20, 2020 (edited) I have a Dell T320, Xeon [email protected], 20gb ram. I have three disks, two are 7200 rpm and one is 5200rpm. Fourth disk is 5200rpm and used as parity. I have a 240gb SSD connected as cache. All are hard-wired via SATA internally. (Older machine, honestly not entirely sure which version of SATA it's running.) I have two shares, one called "xfer" and another called "share". All data on "xfer" is on Disk 2 and "Share" on Disk 3. I am moving data via Windows Explorer/SMB between each share. Transfer speeds are varying between 500kb - 5mb/sec. I'm not sure what my expectations should be in this case, but that seems awfully slow. What are best practices for transfer speed? Should I not use SMB? Edit: I found the doc here related to Midnight Commander. Maybe I'm an idiot, but I'm trying to do some basic stuff - I hit 6 to move something but nothing happens. My question on SMB still stands though. Thanks in advance. Edited October 20, 2020 by Zudnic Quote Link to comment
JorgeB Posted October 20, 2020 Share Posted October 20, 2020 Array disk to disk transfers never were very fast with Unraid, worse since it's not possible to use turbo write, still 5MB/s is on the low side, unless it's mostly small files, if you're using Widows 10 SMB is fine since the transfer is still done locally, you can post the diags during a transfer to see if there's anything there.

Zudnic Posted October 20, 2020 Author Share Posted October 20, 2020 (edited) @JorgeB Thank you. I am doing this on a Windows computer over my local network. Diagnostics attached.

JorgeB Posted October 20, 2020 Share Posted October 20, 2020 Diags show writes going to disk1 at about 30MB/s, that about right for array disk to disk transfer. Quote Link to comment
Zudnic Posted October 20, 2020 Author Share Posted October 20, 2020 @JorgeB thank you! If that's the case I'm confused as to why Windows shows it going at 850-1200kb/sec right now? Quote Link to comment
JorgeB Posted October 20, 2020 Share Posted October 20, 2020 Enable speed stats on Unraid and check speeds there, but Windows speeds should be accurate, Unraid speeds can also go up and down, I can only see the speed at the moment the diags were captured.

Zudnic Posted October 20, 2020 Author Share Posted October 20, 2020 Thank you, I didn't know about that. It's showing the transfers in the KB/s range. Quote Link to comment
JorgeB Posted October 20, 2020 Share Posted October 20, 2020 Are those large files? Quote Link to comment
Zudnic Posted October 20, 2020 Author Share Posted October 20, 2020 No. Approx 18k files across 6.3gb. Quote Link to comment
