December 14, 20205 yr Hello, I have been looking through threads for any solutions. I have come across a lot of solutions, but none seem to be the fix for me. I am struggling to get any transfer speed greater than 1 mbps. I have my unraid connected directly into my 10Gb switch along with my Mac Pro which I am transferring files from. Disks Include: 2 x 4Tb Ironwolf NAS Drives, One is a parity 1 x 1Tb Barracuda SSD in Disk Array 1 x Gen 4 FireCuda SSD as Cache The thing that confuses me is that when I benchmark this drive from my mac I get 920ish Mbps, but when I try to transfer a file it is sluggish 1 mbps. I'd settle with anything over 100 mbps. The files I am trying to write are local on my mac device (not in icloud or something). Edited December 14, 20205 yr by KRF
January 2, 20215 yr Hi KRF, im also using mac os and i had lots of problems in the beginning using UNRAID. What surprised me, is that the cache drive didn't speed up transfer very much. Which is the same for you... What i found out while testing is, that the transfer speed strongly depends on the protocol. I assume you are using SMB... because it is recommended. The weird thing about this is, that apple itself recommends the SMB over AFP, but AFP is much faster with the current UNRAID version... Another important point is, which files are you transferring? -> i always tried with a 7 GB .iso image (this gives faster speeds than a lot of small files) From SSD (Mac) to SSD (UNRAID) over a Gigabit network i got the following speeds: - AFP: full speed, around 110 MB/s which is perfectly fine (theoretical 125 MB/s) - SMB: everything between 0 and 120 MB/s - SMB seems pause every few seconds... results in around 70 MB/s in average -> on a windows machine this is stable I also found out, that in the next Version of UNRAID: I think i tried "beta30" - the SMB integration is FASTER than at the moment and AFP is completely gone (as expected from the recommendations) ... so i hope this helps you a little... i know its not really a solution for now... just sharing some thoughts, ideas and measuring.
