Title: Raid0 and 1Gb transfer rate
Post by: Zardoz66 on March 12, 2009, 05:28:36 PM

Question for you people that are running RAID0 on a gig network. What are your transfer rates like? do they seem better then other modes? or about the same making it a limit of the SATA contoller on the unit...

thanks

Ever thought about using the search function?

RAID0 performance does not differ significantly from RAID1 (or any of the others for that matter) and maxed out for me at around 30MByte/sec on gigabit with 9k jumbo frames.

Please note that the hardware you are using at the other end of the test also has an impact on this measurement.

Yes I did, and even though none of the topics are about about my specific question. I was able to derive this from what has been talked about.

basically the DNS-323 is bottlenecked.

from what I see the speed advantage that a RAID 0 can give you does not help as the DNS-323 controller does not preform well.

as for your post on raid 1 and raid 0 performance there is huge gain if the controller is any good however I do agree that the other end has play with that.

I will Polly test this out myself with the 323 and my iRAM

Correct me if i'm wrong but i believe this unit uses software Raid which adds to the overhead of processing.

You're not wrong - but - there's not a whole lot of processing required to run a RAID0 or RAID1 array.
