MaxConnect offers Direct Backplane Ready Attachment for 2.5 inch or 3.5 inch SAS/SATA Hard Drives or SSD Disk Drives
http://www.maxupgrades.com/istore/index.cfm?fuseaction=product.display&product_id=189

Okay I think I'm having a senior moment? Does this upgrade the backplane from SATA II to SATA III thereby eliminating the need for custom outward facing drive sleds and additional SATA III cabling?

My current setup:

Mac Pro 4,1 (2009) flashed to 5,1
2.66 Xeon Quad Core
High Sierra 10.13.6
16GB DDR3 ECC 1066Mhz RAM

Bay 0 Upper: Superdrive DVD/RW
Bay 0-1 Lower: Hatachi HDD SATA II 3GB/s (Replacing with SATA III HDD)

Bay 1: WD Blue 3D NAND SATA SSD 6GB/s
Bay 2: WD Caviar Black HDD SATA III 6GB/s
Bay 3: WD Caviar Black HDD SATA III 6GB/s
Bay 4: WD Caviar Green HDD SATA II 3GB/s (Replacing with SATA III HDD)

I may go all SSD but for now this is the cheapest option. I still have to upgrade the GPU and have it flashed with MAC EFI or go with a dual GPU setup and possibly dual monitors, haven't settled on anything yet.

It's a SAS RAID card, forget that. Apple kills support for 3rd party RAID cards at every new macOS release.

Honestly, just stay with SATAII speeds with your hard disk and invest into a NVMe PCIe SSD. You will get much more throughput from your money.
I was trying to avoid PCIe SSD due to the 300W combined maximum for all PCI Express slots. I still have to upgrade the GPU and was thinking about a dual setup so I can boot from GT 120. If I go that route all 3 PCIe slots will be filled.

If you use a PCIe SAS RAID card, you will use 10 times more energy than a PCIe NVMe SSD, maybe much more.

BTW, every way you will use to improve disk throughput, will need a PCIe card…

What issue are you experiencing that you need to solve? Are you experiencing a performance problem which SATA-III will address?
Yes, all my drives will be SATA III but operating on a SATA II interface. I'm getting better than expected speeds on the SATA SSD but when transferring files between the HDDs it's like driving with the emergency brake on.

Even with a PCIe RAID SAS card, you will not get much improvement from single drives, only with a RAID array.

What your main application? Maybe we can suggest something that will improve.

I understand you'd prefer SATA-III because your device are SATA-III but that doesn't answer the question of what issue are you trying to solve (unless the issue is you do not like running SATA-III devices off of a SATA-II bus)? What do you expect to achieve by using SATA-III?

Forget the RAID arrays, just buy a 1TB NVMe SSD drive like Samsung 970EVO and a Angelbirds Wings PX1 adapter.

When you have both at hand, do a BootROM dump, compress and PM me it. I'll insert the NVMe EFI driver on your firmware and you will boot from the NVMe drive like you boot from your hard disks.

You can get this speeds with a NVMe drive plus a HighPoint SSD7101A card: #1068

You da man! When I get everything squared away I'll send you a PM.

Thank you.

Hmmm... My old Caviar Green SATA II is out performing my newer Caviar Black SATA III? The WD Blue SATA SSD seems to be right on par with SATA II bus.

If you want to buy Angelbird Wings PX1, Adorama store on eBay has the best price, $59 with shipping. Amazon had HighPoint SSD7701a promo, $275 each.
Looks like the HighPoint SSD7701a is PCIe 3.0

My specs:

Three open full-length PCI Express expansion slots5

One PCI Express 2.0 x16 slot
Two PCI Express 2.0 x4 slots

All slots provide mechanical support for 16-lane cards
300W combined maximum for all PCI Express slot

While the benchmarks look impressive I have to ask: How do you expect they will increase your productivity?
Are you here to interrogate me or will you be adding something helpful to the discussion? Your line of questioning from the start has been a bit Gestapo-ish.

HighPoint SSD7101A has a PLX bridge that uses the 16 PCIe 2.0 lanes to combine all into 4 PCIe 3.0 4x connections for M2 SSDs, that's how people who have this card can get double throughput from SSDs than the common adapters. The magic is all done by the PLX chip.
