JonathanM Posted April 23, 2021 Share Posted April 23, 2021 Faster disks or controller, depends on where the bottleneck is. Typically it's the disks. Quote Link to comment
MrYoshii Posted April 23, 2021 Author Share Posted April 23, 2021 (edited) I used the DiskSpeed docker to check all disks they are all fast enough. I think there is something else solowing down the whole maschin... homeserver01-diagnostics-20210423-1823.zip Edited April 23, 2021 by MrYoshii Quote Link to comment
JorgeB Posted April 23, 2021 Share Posted April 23, 2021 Parity disk is SMR (also disk6), but parity can really have an impact on all write performance. Quote Link to comment
MrYoshii Posted April 23, 2021 Author Share Posted April 23, 2021 i do not think it should be so slow.. Quote Link to comment
JorgeB Posted April 23, 2021 Share Posted April 23, 2021 Those are read speeds, SMR is slow for writes. Quote Link to comment
MrYoshii Posted April 23, 2021 Author Share Posted April 23, 2021 but not 10 MB/s slow Quote Link to comment
MrYoshii Posted April 23, 2021 Author Share Posted April 23, 2021 its still goin slow as hell.. is there a way to swap the slow wd drive with a faster one from the array? i can move all the data from one of the drives and use this one as parity. Quote Link to comment
JorgeB Posted April 24, 2021 Share Posted April 24, 2021 12 hours ago, MrYoshii said: but not 10 MB/s slow Very possible to get 10MB/s writes with SMAR drives, I get that with some of mine when they hit the SMR wall, you should at least avoid SMR for parity since that will impact writes to any array device, even non SMR.

MrYoshii Posted April 27, 2021 Author Share Posted April 27, 2021 i have now swaped the SMR drive i will check and if its still slow as hell i will post again ^^ Quote Link to comment
