So wait, you are changing more than one variable in that test?
| no.I'm speaking about the overall change between single disk and optimal RAID 0 config. Quote:
You said "Just enable it, it won’t do any harm" except it can cause harm in the form of data loss.
| it's ON by default for WD HDDs, and the "data loss" might be less than you think ;) Quote:
RAID-1 needs to write to both disks but it can (essentially) be done simultaneously so the typical expectation is RAID-1 has the same write speed and up to 2x read speed as a single disk.
| theoretically yes, but practical experience shows slower write speeds with RAID 1 compared to a single disk setup |
