Post your performance results
I thought it might be interesting to see what kind of performance everyone is getting with IO Meter so that we can compare what we're getting. So I thought we could all post our results in this thread...
Minor update
Changes:
ReadyNAS NV Rev B
2 x HGST 7K250 250GB HDDs
2 x HGST T7K250 250GB HDDs
Firmware: RAIDiator™ v3.01c1-p3 [1.00a032]
Online, 37% of 681 GB used, X-RAID (Expandable RAID), 4 disks
All streaming services disabled (was HSMS, uPnP)
Results:
Immediately after expansion
Jumbo OFF, via Switch
256K_Write 11.754537
256K_Read 21.188849
Which I found disappointing since I had assumed that a stripe set would be faster than a mirror, at least for reads. Thinking perhaps that the expansion had not best optimised the test file I deleted it and allowed IOMeter to recreate it.
256K_Write 15.476495
256K_Read 25.818728
Much better, and a slight improvement from 2 disks
NOTE: there was also a reboot of NAS and PC after deleting the test file, so this might have had some influence too.
NV Jumbo On, via Switch, NIC @9k
Run 1
256K_Write 18.467976
256K_Read 20.927655
Run 2
256K_Write 20.036544
256K_Read 21.021096
I did two runs as I saw some quite large access times for the first run. Run 2 is better but no real change from 2 disks.
I also discovered that my switch does support Jumbo Frames, which is :D
As before since reads far outnumber writes in quantity and priority, I am running with JFs disabled.
