Can someone use this:
with this and get 9 ports???

I find it interesting that my 3TB Parity being a 6 GB/s Red running OB is just as "fast" as one of my 3TB data 6GB/s Reds running on the bus throttled at 3 GB/s. Not that I planned it this way, but it is interesting to see it proven that a spinning disk has a hard time getting 6Gbps speeds. I guess the only drives that can saturate 6Gbps SATA connections are solid-state disks.

Can I move disk connections around on the MB and cards without having to rebuild them in the array?
I guess I have a few slowpokes.

Sorry for the delay...weekends, kid activities, etc, etc.
The server is set up with:
M/B: ASRock - B75 Pro3
CPU: Intel® Core™ i3-2100 CPU @ 3.10GHz (5x SATA 3Gb/s & 3x SATA 6Gb/s connections on board)
Memory: 4 GBalso installed
2x Adaptec 1430SA cards on PCI bus
Adapter 1 has 3x 2TB WD Green Data disks
Adapter 2 has 2x 3TB WD Red Data disks & 1x 1TB WD Black Cache disk + 1x 3TB WD Red disk (precleared & ready as backup)OnBoard
1x 3TB WD Red Parity
1x 2TB WD Red Data
1x 2TB WD Black Data
3x 2TB WD Green Data
1x 2TB WD Green (precleared and ready as backup)
I use 3 SUPERMICRO CSE-M35T-1B 3 x 5.25" to 5 x 3.5" Hot-swap SATA HDD Trays in a tower case configuration.
Can I move disk connections around on the MB and cards without having to rebuild them in the array?

Last checked on Thu 01 Feb 2018 11:04:04 AM EST (two days ago), finding 0 errors.
Duration: 11 hours, 4 minutes, 3 seconds. Average speed: 75.3 MB/s...for an array of 1 parity and 10 data disks and 1 cache
1x 3TB WD Red Parity
2x 3TB WD Red Data
1x 2TB WD Red Data
1x 2TB WD Cavier Black Data
6x 2TB WD Cavier Green Data
1x 1TB WD Cavier Black Cache
I get some slow write speeds to the array (5MB/s direct write to parity then share, so I am not using the cache to it's fullest extent and mainly using it as a staging drive for docker programs).
I want to get a 2nd parity (probably move up to a 6TB Red). If I use 2 parity drives, should they be = in size and how bad will this slow things down?

You are absolutely correct...my bad for not looking hard enough at the connections first.
But I think either is good in its own right for unraid connectivity and controlling SATA. Yes?
