May 15, 201511 yr Just installed my 8tb parity drive and started a parity sync and it says eta is 1.5 days do you think two 4tb hard drives in raid 0 would be ok for my parity to make it go faster?
May 15, 201511 yr Author ahh thanks for the link, I guess I could have done a search for that but I was just being lazy But I guess it looks like when I get a couple more 8tb drives I can use 3 of my old 3tb drives and make a raid 0 array for the parity. Or do you think the speed increases wouldn't be worth it and I should just add those to the storage? the 3x3tb would be bottlenecked by the 8tb read speeds I guess right? so does around 200Mbs sound right for the parity speed in this set up?

It will slow down as it gets to inner cylinders. There is a thread or two about these drives and tests of them. Did you decide to buy these without research?
May 15, 201511 yr Author no I did some research and came across a thread that said they work very well for the unraid environment (including parity), I just didn't know how long it would take for a parity check. At current speeds it says about 16 hours (127MB/s), which I figure will be close to 20 to 24 to finish. I have my parity to sync every week right now but if I leave it how it is I might have to change it to once a month. So I am just looking for some other solutions to make it go a bit faster.
