Thanks for all the help, Ill test it out later today.

Ill give it a test and see, its mostly video projects I move off my desk top into unriad, I was reading a post you tested this in. Is this the command you used "sysctl vm.dirty_ratio=90"? Where is the file on the flash "flash/config/disk.cfg"?

Ok, I assumed it would cache more, is this a commonly changed setting or is that bad practice?

Does it not cache the entire file in ram then write to disk ? Would raiding "0" the SSDs be any better ?

So Im able to achieve about 1GB/s for about half the transfer "lets say for a 5-10Gb file", then it drops to about 200-300Mb/s, then tanks to about 20-30 Mb/s. Im not sure why. Im not sure what my problem is. Is this a parity issue or my SSD cant keep up ? How would I trouble shoot this?

What kinds of SMB file transfer speed in windows with 10gb networking and good SSD cache disk should I be able to achieve?

Mind blown.... Great video So is there a way to increase parity ? So you can have more than one drive fail at once?

LOL kinda what I was thinking thanks for the info..

Made the switch to unraid last night, long time freenas user. How does Parity work in unraid? I understand how zfs raids work in freenas, in regards to number of disk and to size but when I set up unraid last night it only shows one Parity disk? Is this normal or do I have to add more Parity disk to have the entire array protected? I have set one of my 3TB disk to the parity disk and one 3TB in the array along with 8 1TB drive. my set up M/B: Supermicro - X9SCL/X9SCM CPU: Intel® Xeon® CPU E3-1280 V2 @ 3.60GHz Memory: 16384 MB lsi 9240-8i flashed to lsi 9211-8it mode HBA 8 1TB hds and 2 3TB hds
