WD Red Vs Seagate Ironwolf - T340 TrueNas

Mikey · 17 Dec 2021 at 23:07

I've got some 3TB Dell NL SAS drives in my TrueNas setup, 4 x 3TB, but TBH they're just so damn loud, so I'm looking at swapping them out for CMR WD Red or Seagate Ironwolf drives of prob similar capacity. Server has 8 bays, but only using 4 atm.

Currently in a RAIDZ2 setup, although wishing I'd gone for 2 x mirror setup for the vdev.

Any views on how loud the above disks are?

The old Red 3TBs are very quiet. I had six in my NAS and there was a bit of clunking when they were accessed but virtually no rotation noise so I'd expect the Red Plus to be the same.

I replaced the 3TB Reds with 6TB Ironwolfs (Ironwolves?) and I don't think they're any louder.

I have one iron wolf I use in a hotswap cabinet along with others, it seems lighter than others, potentially a little quieter but the one thing i have noticed is it seems very cool given that when i swap it out it's usually only been powered down a minute before. Some of the others I have (especially the WD blacks) get warmer, or a lot warmer

That's probably down to the difference in spin speed. The Blacks are 7200RPM and the Iron Wolf is probably 5400 or 5900.

could be, but for archival storage, i'm happy with the slower spin speeds
