Hi,
I have a Thecus 5200BR Pro
with 5x750GB Raid 5
And it is sssooo slooowwwwwwwwwwww
I am not complaining about overall transfer speed. It's all right, I knew it was around 30MB/s ( I got ~ 45MB/s when using it without RAID5, single disk)
The parity is written to the 5th disk after some time. So all gets stopped and parity is written.
Why is that??
This way whenever you're copying something to the device, and guess what it's a NAS for ... I say whenever you copy something to it, you are not able to listen to music, watch movies ..
it all get stopped after 7 sec or so, then back again, then stop again ...
Ehy? Is there a way around this?
Thank you !! This way it's really useless. I might have to sell it.

Strange. If have 5 * 500GB Samsung HD in RAID5, watch videos, listen to music and write files and have no interruption. A question to that : do You use a Windows Vista Client for watching videos, listen to music and writing files ? If Yes, then this is a known bug of Vista. See i.e this article: blogs.zdnet.com/hardware/?p=709br Peter PS : Data and parity is distributed over all disks in a RAID5 |

Try SMB instead of AFP, and see how you go.

I tseems it was AFP, now no problem with writing/reading from SMB ..
iTunes though wants on the mac the volume to be mounted as AFP to be able to read the music library ..
thank you all ...
and for Thecus people ... please fix this !!!!!! ...
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The fastest transfer speed I can obtain reading from my 5200 is ~38MB/sec yet the disk drives are capable of over 70MB/sec. I've tried jombo frames and even tried link aggregation accross all 4 GigE ports without any significant performance difference. Does the RAID not do look-ahead buffering or employ elevator-seek disk controlling? It should not be slower than the drives, anyway. What gives?

I agree, new user here with n5200 pro! I created a ram disk to be sure it wasn't my disk that was the slow one...
37 MBps! Not bad, but not great with RAID 5.
