Re: stripe size
what is the stripe size of an X-RAID2 array? is it a fixed setting or can it be changed?
I know that Netgear don't wan't to make troubles to it's own users - it's obvious but...
Ready NAS ultra 6 (intel ATOM D510 - not plus intel pentium) - 6x 2TB WD20eurx + 4GB ram + jumbo frames (also on switch and PC and all between) + cables not longer than 10m on each side of switch + pionieer teaming in adaptive loadbalance mode (tested with LACP - not diff at all on file transfer between LACP and pionier teaming)
Guess what speed i get when i'm write a one file ex. 10GB with drag&drop on WIN 7 x64 or 8.1 x64?
You guessed - it's not 128MB/s - not even 100MB/s - and somtimes it's below 70MB/s - suprised?
When i turned on jumbo frames it was a diffrence - yes in writes ex. 50MB vs 70MB. But it still NOT 128MB?
When read file it's 100MB+ in most - i can't say the cables are wrong or something.
Writes on disk are hmm... SLOW and it's not the fault of HDD itselfs - i think.
Intel Atom D510 + 4GB ram + 6x2TB can't do any faster? or it's the chunk size, raid5 or shit know what?
One HDD (wd20eurx) can read and write 135MB/s + on beginning (tested on PC) - they are all in raid5.
Maybe Raid5 is the problem? - but i need to have any opportunity to get data back on drive failure.
