Hi everyone,
as per the subject, I'm getting very slow write performance on a 3
disk raidz1-0 zpool. IIRC the disks are early 1tb WD green drives.
Not sure what i should tell you, but during copies of large 10gb+
files rsync is showing around 2MB/s, which is terribly poor i think.
Sorry if this is a common question, not sure what to do.
