How do you pros do it benchmark your servers?
I got raid 6 setup and going with cache and bbu. I'm starting to copy data into the new raid drive and Windows is indicating 119MB/s at best.
Granted the source disk is a sing disk on AHCI but its 6Gb/s too. Shouldn't I be seeing much faster speeds?
New raid, new dual CPU board, DDR4 Etc.
4 hours to move a 300GB OwnCloud Folder.
This cannot be right!
I have both processors installed but I only have 32GB of DDR4 and another 14 slots to fill but I need to slow down on the purchasing :)

6Gb/sec is the maximum the *interface* can handle, not the speed of the disk itself. 120MB/sec is actually pretty good. The only way to get faster is more disks, and honestly RAID6 is expensive too. Parity calculations will slow writes by a chunk.

Thanks Cliff. I believe it was you that had recommended a benchmark tool in another one of my Qs several months ago.
Do you recall what that was? I would like to test this build if possible.
That speed is within the ballpark for a desktop class rotating magnetic media drive.  Does not indicate a fault.

In many cases, windows built in performance monitors can give you insight into bottlenecks. But if you want to stress test, crystaldiskmark is pretty good for that.

I think I did this smart this time. Or at least not as dumb...
ss m2 boot dive 120GB. 4 WD Enterpise drives in a raid 6 array on a megaraid 92261-8i and an internal 3TB Red For Host backup and 2TB Red hot spare embedded in the server.

Note: I purchased the Enterprise WD Yellow drives because no raid card (except elcheapo Highpoint Rocketraid Card that created an array on these drives in the first place) can see any of my new WD Red drives no matter how many times I clean them with Diskpart or anything I tried for several days.
I have another thread about this issue and no one seems to have an answer for it.
