Hi all,
How is the Raid performance on UNRAID?
For the following question : I do NOT care about redundancy or backups (only space and performance)
I have 2 identical machines - each with 12*8Tb drives.
One is running Ubuntu 20.04 with Raid 0
/dev/md1:
Timing cached reads: 10994 MB in 1.99 seconds = 5523.34 MB/sec
Timing buffered disk reads: 4042 MB in 3.00 seconds = 1347.14 MB/sec
root@Storage4:~# sudo hdparm -Tt /dev/md1
Identical machine (UNRAID OS)
/dev/sda1:
Timing cached reads: 9340 MB in 1.99 seconds = 4688.61 MB/sec
Timing buffered disk reads: 30 MB in 3.21 seconds = 9.35 MB/sec
Both machines are Raid0 (as performance is required over backups(I don't mind if I lose all data))
As you can see the performance of Buffered Disk Reads are not even close to being comparable!!

Have I setup UNRAID Array correctly as Raid0?
I'm beginning to think I have not!!!
Thanks for any help/suggestions you can offer...
