takkkkkkk Posted May 27, 2021 Share Posted May 27, 2021 I have an array with 16SATA drives + 2 Parity (8-14TB SATA), and 2 pools (with 1TB SATA SSDs). They're all connected to 4*6 SAS2 backplanes. My array write peaks at around 110MB/s, but then drops to ~55MB/s, the 2 parity drives are shucked wd140edfz, which, from what I read, should give me a decent transfer speed. Other drives are mixture of 8-14TB SATA drives. The 2 pools are made up of 1TB 860 EVO, and I'm getting sustained read/write of ~160MB/s When I'm downloading it downloads using one of the pool (download), when it's completed, it moves to the other pool that has a media share (temp), then mover moves to an array. I'm using this approach because I then have 2TB of buffer storage, so that even if I'm only getting 55MB/s on array, it has enough buffer to move the downloaded files before it runs out of space. However if/when I'm downloading a huge list of files, it 2TB buffer isn't enough, and my downloader starts telling me I'm running out of space. So, I'm trying to see if I can increase array speed in anyways. Any thoughts / Ideas? My Tunable is set as "auto", if that makes any difference. Quote Link to comment

I also didn't see a significant improvements in performance... Quote Link to comment

I'll giver it another shot. May be I could just spin up the drives when I see the pools starting to get full Quote Link to comment
