Hi Till, Thanks for the feedback.
I'm deliberately trying to push the envelope. I believe that ZFS will act as a buffer between drives and run at the slowest device speed, but I'm wondering if there is a threshold where ever ZFS will throw up its hands and give up. I'm trying to make a ZFS pool focused on resilience, while using drives that are already laying around. Performance is understandably going to take a hit. The vision is a pool consisting of a number of mirrored vdevs. I mean... if I had a load of hard drives on SATA and connected another drive via SATA to USB adaptor, would ZFS still handle it and slow down, or would it throw a fit? Many thanks, Michelle. On Sat, 2022-10-29 at 12:33 -0300, Till Wegmueller wrote: > Hi > > It can get yarring.
