Indusbird Posted May 17, 2020 Share Posted May 17, 2020 Hello all, I apologize for another slow read/write thread but I have read through tons of other posts here, on reddit, and elsewhere and could not find anything that closely enough resembled my setup and problems. I finally rebuilt my NAS and pulled the trigger on UnRAID at the recommendation of several friends and coworkers. Everything went relatively smoothly but I've been very disappointed in the read/write performance, especially compared to the Lacie NAS this is replacing. Reading large single files from the server seem to top out around 25 MB/s and writing large single files to the server top out around ~40 MB/s. For the writes, I understand there are limitations to the write performance in UnRAID. However, shouldn't a single data drive + single parity drive configuration with Turbo Write enabled be getting closer to the max write speed of these drives? As for the read speeds, these are my biggest concern since they're so far off from my expected performance. Thanks, Nick Here are my specs, settings, and things I've tried for reference: -Initial parity build is completed -Turbo Write enabled -No known drive issues -iperf tests show no issue with network connection. Also tried direct ethernet to server. -Tried transfers between UnRAID server and Macbook wired to ethernet, Windows laptop wired to ethernet, and another server on my network. -Tried coping via SMB mounts in Mac/Windows, rsync, and scp. Specs and info: UnRAID 6.8.3 Intel i7-4770k Gigabyte Z87N-WIFI Motherboard w/ 1x Intel Gigabit Ethernet + 1x Atheros Gigabit Ethernet 8GB RAM 2x 8TB Seagate IronWolf Pro NAS (1 Data + 1 Parity) No cache drive (yet). Plan to add one soon. tower-diagnostics-20200517-1341.zip Quote Link to comment

JorgeB Posted May 18, 2020 Share Posted May 18, 2020 The array shoudd be much faster, especially with just one data drive which makes work similar to a RAID1 array, two things you can test, copying directly to a disk share instead of user share, you can enable disk shares on settings -> global share settings, then copy to \\tower\disk1, another thing would be to add an SSD as cache, for either test do a standard SMB copy using Windows explorer, from a Windows 10 PC if possible.

Indusbird Posted May 21, 2020 Author Share Posted May 21, 2020 Thank you for the suggestion and I apologize I've taken so long to get back! I was finally able to try out the disk share suggestion. As far as I can tell it is producing marginally faster read speeds (28-30 MB/s), but is not helping the write. I am definitely planning on adding a cache drive soon, but I was hoping for better base performance without it. Quote Link to comment

There should be, with that array config you should easily get gigabit line speed with reads and writes, something else is going on there. Quote Link to comment
