RN102 Expected Performance?
I purchased an RN102 a few weeks ago and have just gotten it around to setting it up. It was the preconfigured model with 4TB (2x2TB Toshiba Drives). Reading the report at smallnetbuilder, it looks...
Obvious questions but not asked yet :
Is the volume rebuilding ? (I believe it would take 14 to 24H for raid1 with 4To)
Is your network OK ? (no TCP retransmit, no lost packets, your mac no using wifi as top priority even with cable plugged...)
Do you have background apps like torrent downloader, a server app or that kind of thing ?
For info, my RN104 (which has the same hardware with 4 disks) does 90-100 read and 40-50 write with 4 seagate NAS HDD (test OS is win2012R2 with two caviar black in raid0 via CIFS/SMB). The limiter is the CPU. Maybe you should try to disable unused protocols and apps to keep CPU usage low. Speed fluctuates with file size and sometimes, the NAS pauses (drop to 0bytes/s for 2 or 3 seconds, don't know why).
Raid should be splitting between disks on the fly, otherwise raid5 would be a nightmare ;) and raid1 useless if a disk fails before the resync.
if you have enabled SSH (and then already ignored the warning), you should be able to see if the CPU is crawling or not with "top", if you see high %WA, then check network and disk.
