I have a Pro 6, I create volume with 5 disks (3TB each). After sync completed, I added 6th disk as dual redundancy.It is very slow to restrip after 6th disk is added. Is this normal? It will take more than 10 day!!!!!!Configuration: RAID Level X-RAID2, 6 disks (with dual redundancy) Status: Restriping 1% complete, Time to finish 276 hr 8 min, Speed 2891 KB/sec RAID Disks: Ch 1 : Seagate ST33000651AS [2794 GB] 2790 GB allocated Ch 2 : Seagate ST33000651AS [2794 GB] 2790 GB allocated Ch 3 : Seagate ST33000651AS [2794 GB] 2790 GB allocated Ch 4 : Seagate ST33000651AS [2794 GB] 2790 GB allocated Ch 5 : Seagate ST33000651AS [2794 GB] 2790 GB allocated Ch 6 : Seagate ST3000DM001-9YN166 [2794 GB]

Restriping can take a long time particularly when migrating from single to dual-redundancy.What services do you have enabled? Any add-ons installed. Disabling unneeded services should help speed up the syncing a bit. If a service is using a lot of CPU that can really slow down resyncing big time. Recently a resync was crawling at 1MB/sec on my Ultra 6 (has a much slower CPU than your Pro 6). After disabling a service that was hogging CPU resources the resync sped up to 30 something MB/s

I turned of the following services:Bonjour serviceUPnPReadyDLNAFile Protocol:AFPHTTPRsyncStill very slow:Time to finish 256 hr 57 min, Speed 3103 KB/sec

No add-ons. I rebuild the volume.

Any data on the unit yet?If not, you may wish to do a factory default (wipes all data, settings, everything), open RAIDar (http://kb.netgear.com/app/answers/detail/a_id/20684/), click Setup and choose X-RAID2, tick the dual-redundancy option and confirm your choice. This should be a lot quicker.

Thank you. I was using 4.1.6. Upgraded to 4.3.4 and rebuild volume with dual redundancy.

That's the RAIDar version not RAIDiator (still good to upgrade to the latest RAIDar though).

What version of RAIDiator x86 are you running (latest is 4.2.22)?

RAIDiator 4.2.22 (for Pro 6)
RAIDar 4.3.4 (just upgrade)

BTW, I have a NV+ RAIDiator 4.1.10 [1.00a043]. Pro 6 Network bandwith kills the NV+.

Well the NV+ (v1) is using hardware that's pretty much the same as a product released back in February 2006. The Pro 6 was released late 2010. Of course one would expect a big performance difference. The NV+ uses a slow Infrant CPU whereas the Pro 6 uses a very fast Intel one.

Do you have any experience with network teaming?
Round Robin vs. XOR, which is robust?
