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?

Can someone use this: IO CREST SI-PEX40138 Internal 4 Port Non-Raid SATA III 6GB/S with M.2 B-Key 22x42 Pci-E X4 Controller Card for Desktop PC Support SSD and HDD with Low Profile Bracket. JMB585 Chipset with this and get 9 ports??? IO CREST Internal 5 Port Non-Raid SATA III 6GB/s M.2 B+M Key Adapter Card for Desktop PC Support SSD and HDD. JMB585 Chipset

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 GB also 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.

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?

Thanks everyone. I'll see what I can do about swapping out the older local drive.

I tried the Lite version of the link provided to test file transfer of a 1024MB file from my Win7 pc to the array. Results are attached.

>Do you have a separate gigabit switch or are they plugged into a router with gigabit LAN ports? 2 switches: -Server into a NetGear Prosafe GS116 (Gigabit) -Win7 PC into a NetGear Prosafe GS105 (Gigabit) >If so, what make/model of router? Technically 1 router and 1 Access Point: -Router: Linksys E3200 (gigabit ports) out to Internet -Access Point: Linksys WRT610n (gigabit ports) >Are the server and test PC's plugged into the same gigabit switch? Yes & No, the Win8 is into the GS116 & the Win7 is into the GS105 then into the GS116 "hub". Server is in the basement into the 16port switch where all bedrooms are pulled to central access panel. Win8 pc is wired at a desk direct to the basement. Win7 is at the TV along with the AVR, DishNet receiver, etc...requiring more plugs hence the 5port then to the wall that is direct to the "hub" switch. I could test a direct to basement connect for the Win7 temporarily bypassing the 5port, but that would ONLY be a test as I wouldn't run another pull and ultimately rely on the 5port anyway. >Are all devices negotiated at 1000/full? No on the Win8 due to internal card limitations. Win7, assuming yes according to the ipconfig info as well as the dual lights on the switches. >What type of cables are you using?Pre-made or did you crimp them yourself? Crimped by installer during the low-volt install throughout house at time of build 8 yrs ago. All CAT5e except for minor "jumpers" to the routers/switches which are store-bought CAT6.

yeah...I got the MB / mb down pat based on my previous life. The #3 metric was puzzling and didn't know if the 7 vs 8 winders had issue. I appreciate the net-net at the end...essentially, "quit 'cher whinin'" but I thought I was reading that array with parity may be capable of 80M (big B) speeds internally. My Parity checks will avg. 50-70M(big B) depending...disk 2 is an older EARS that hdparm's at 50-60MB on reads.

Isn't it always about speed...oh, and money. But this time, speed. Version: 5.0-rc12a New build: System: ASRock - B75 Pro3 CPU: Intel® Core i3-2100 CPU @ 3.10GHz - 3.1 GHz Cache: 512 kB, 64 kB, 3072 kB Memory: 4096 Module (max. 32 GB) Network: eth0: 1000Mb/s - Full Duplex Array (mostly on-board 6GB/s SATA plugs) Parity: 3TB Red Cache: 1TB Black Data: 1x2TB Red, 1x2TB Black, 4x2TB Green Trying to squeeze every bit of the speed out of the setup to get fast writes to the array. I've attempted to look and try certain actions based on every Tom, Dick, and Harry's recommendation, but not overly confident on the "why" to do something other than just the simple act of trying it. test PC: Win8 HP AIO on a 100 Mbps hardline Moving 1943818KB file and reporting what Win8 says the speed obtained: Array -> C:\ (WD 1TB Green EARS): 11.4MB/s C:\ -> Cache: 11.4MB/s Cache(AppData share) manually Win8 -> Array: 6.0MB/s C:\ -> Array: 11.4MB/s Cache(AppData share) manually using MC -> Disk 6 (2TB EZRX): 25.5MB/s test PC: Win7 Dell on a 1000 Mbps hardline Moving 1943818KB file and reporting what Win7 says the speed obtained: [*]Array -> C:\ (WD 80GB SE 7200): 33MB/s [*]C:\ -> Cache: 36MB/s [*]Cache(AppData share) manually Win7 -> Array: 26MB/s [*]C:\ -> Array: 34MB/s --- Do y'all think I am maxed out? Hearing/reading about 80's and 90's...is that all because of spin speed avg for my array? Secondly, if anything is done on the array (read, write, browse) the speed of the copy dips dramatically . I am not running Cache-dirs. Thirdly, would a syslog following a reboot help those much higher in the food chain determine if I am "tweaked"?

diggin the SuperMicro's for almost 3yrs now.

SMART test attached from "old" parity drive.

Great idea on a SMART for the Parity. Since the array is puking data bits into external buckets right now, I am not going to spin 'er down, but will surely review her status when I can pull it. Surprisingly enough, my server is my backup of my multiple desktops that are used for those critical circumstances. Doing a backup of the critical data on the server is normally done quarterly, and guess when calendar qtr end is...yep. It all seems to happen all at once. The other data that is on the server are Hollywood hits and some Nashville noise. I guess I'll put in this MB: ASROCK B75 PRO3 with an i3.

Thanks guys. Ok, I'll consider #3 going forward. Frank, I won't have a 2TB that would be stable enough to rebuild the Parity drive once I have satisfactorily backed up the data. I understand the "shoulda got a 3TB" statement, but the 2TB was my "get it up and going" drive that would later live nicely in the array. If I could stand up the 3TB as the "new" parity, then I would not really need the 2 to be a 2....since I am working with the drive size limitation of 4.7 on the recovery phase. I read somewhere that SATA cables are best left unbundled in the case....so no pretty wire-ties?
