September 8, 20178 yr So new to the joys of unRAID but been muddling through I was on windows 10 being used as a sever before hand. with that being said I been slowly (sometimes painfully slowly) moving my data into unRAID. I just finished a preclear on a 4tb drive and went to add it and said I could not as it was larger than my parity (also 4tb) so I sucked it up and moved the parity drive to my array and set my freshpre clear to be the new parity. It is maxing out at 9MB/s for the rebuild process which seems like it is wrong. my local disk transfers were pegged between 20MiB to 500Kib a sec using unassigned devices and Krusader. When I switched over to unraid I took that time to update some of the system (Sata controller card, more memory, hot swap bays etc) I am just not sure what to check or what could be going on. I have attached my info screenshot as well as my array and parity info. the hot swap bays are: ICY DOCK FatCage MB155SP-B x3 sata cables are: RELPER 6pcs SATA III 6.0 Gbps Cable with Locking Latch (blue) x15 sata 10 port pci-e card is: Ableconn PEX10-SAT 10 Port SATA 6G PCI Express Host Adapter Card hopefully someone can give me some insight here as I think I am going nuts trying to pinpoint the bottleneck.
September 8, 20178 yr Author here are the smart test logs for all my current drives minus flash and cache. My 4TB drives are connected to the motherboard the 1, 2, 3TB drives are hooked to the controller card.

September 8, 20178 yr Author ok after some more research which I should of done to begin with to be honest.. it sounds like it is the sata controller cards fault. Anyone have a suggestion for an alternative that wont break the bank? I need 16 ports. https://www.amazon.com/gp/customer-reviews/R3AOHV2LS9VXLR/ref=cm_cr_dp_d_rvw_btm?ie=UTF8&ASIN=B0177GBY0Y#wasThisHelpful EDIT: looking at the LSI SAS9201-16i any thoughts on that before I bite the bullet as about 75$ more than I already spent on last failure.

September 8, 20178 yr I have 5 LSI 9201-16i's. They work great. I got 112.2MB/s average parity check speed on an 8 & 6TB mixed drive server (would go up if all my drives were 8TB but not sure exactly how much). Another 6TB server got 121.5 MB/s average speed. Just make sure you don't get a counterfeit card. I buy used server pulls and have yet to get a counterfeit card. It may not be as likely with a 9201-16i as it is with a IBM M1015 but I think there have still been reports of counterfeit cards with 9201-16i's as well. Edited September 8, 20178 yr by BobPhoenix

Thank you that is what I wanted to hear, looking on ebay seems i only have a few to choose from with sellers with kinda ok feedback. thanks again for your input!
