Oct 31, 2011 - PCI Express enabled computer with available PCIe slot. Double-click on the “Ports (COM & LPT)” option. MosChip MCS9901-CC. Mac OS 10.4/10.5. For the latest drivers/software, please visit www.startech.com/.
Introduction Stumbling into an Amazon warehouse Deal, I picked up the HighPoint 7101a NVMe PCIe adapter, equipped with a MacPro friendly Broadcom 8747 PCIe bridge at a great price. While Highpoint's acknowledgement of MacPro compatibility was sketchy at best, I ordered one to go along with a recently acquired Samsung 970 Pro NVMe Boot drive. Some Images PEX 8747 48-Lane, 5-Port PCI Express Gen 3 (8 GT/s) Switch, 27 x 27mm FCBGA The ExpressLane™ PEX 8747 is a 48-lane, 5-port, PCIe Gen 3 switch device On to the results Let the numbers speak for themselves. I'm VERY impressed with the near PCIe 3.x performance on a '09 CMP with the Highpoint 7101A PCIe SSD Adapter and the Samsung 970 pro.
Read performance has almost doubled from 1500MBs to 3000MBs. Writes are up 50%. Taking a look under the hood, The 7101A addresses PCIe SSD’s at a pcie 3.0 x4 8.0Gts link, saturating the x16 a pcie 2.0 connection at close to PCIe 3.0 speeds. If there is a Holy Grail of PCIe SSD adapters for the cMP, this may be the one.
970 Pro in a standard m2 x4 adapter with a heatsink. 970Pro in the 7101A. Whilst the 7101a usually costs $400, a qty can be found at enthusiast pricing on Amazon for $275. It’s clear the HighPoint 7101a brings a new level of PCIe NVMe / AHCI Sata Express performance to the 4,1/5,1 that’s unattainable with any other controller. I was able to tear down the Amfeltec Squid 2.0x4 this morning, removing 3 SM951's and their heatsinks that are setup in a software raid. Moving them across to the 7101A, some interesting results came to light: Addressing a single SSD at a time, the Highpoint 7101A is MUCH FASTER than the Amfeltec Squid. Allowing near PCIe 3.0 speeds from our aging mac pro.
Using a Software RAID 0 setup for the Amfeltec Squid, the Highpoint 7101A is about 25% SLOWER than the Squid. Perhaps I need to reformat the array with a different block size. Let's start with BlackMagic Speed Test: Highpoint 7101A 3xSM951 Highpoint 7101A 2xSM951.
FASTER THAN 3X SM951 in 7101A. Amfeltec Squid - 3xSM951 Highpoint 7101A 3xSM951 Highpoint 7101A 2xSM951 Amfeltec Squid - 3xSM951 QuickBench is another great test to show bandwith. Lets look first at 4k - 1m tests: Highpoint 7101A 3x SM951 Highpoint 7101A 2x SM951 Amfeltec Squid - 3xSM951 Lets look at some larger file transfers. Highpoint 7101A 3xSM951 Amfeltec Squid - 3xSM951.

Insight: I had back surgery a week ago and time at my standing test bench is limited. With that our of the way. Off to today's results: I was able to tear down the Amfeltec Squid 2.0x4 this morning, removing 3 SM951's and their heatsinks that are setup in a software raid.

Highpoint 7101A 3xSM951 Amfeltec Squid - 3xSM951. Posting an update. The Mojave public beta & a 4,1-5,1-NVMe modded EFI firmware / 970 pro NVMe install and Boot works without issue. Also reporting that Sleep/Resume causes no issues. Enabling Hibernation support. The Mac Pro powers down without flashing power button, indicating a successful hibernation.
The hibernation file is shown to take up 28G of disk space. From powered off hibernation to operational desktop takes 6-7 seconds. For reference, it usually takes almost 20 seconds for my cMP to chime. Been following your posts and success stories with getting the Samsung 970 Pro NVMe drive to boot on the cMP via the firmware mod. Good stuff and thanks for sharing!!
I am seriously considering the highpoint 7101A card coupled with the 970 Pro 1TB drive. I also just read your nvme guide and was wondering whether you patched your original rom to boot apfs volumes prior to injecting the nvme DXE driver as I patched my cMP 3,1 ROM with the APFS patch (which is working as expected). I did a quick comparison between the two bin files and the only difference was a deletion of 25.5 kilobytes at offset 0x9f70 and an insertion of 25.5 kilobytes at offset 0x14fdbf. Do you foresee any issues in applying both the apfs and nvme patches to the cMP 3,1 ROM?

Without drivers, the Highpoint 7101A card appears to have a max transfer rate of 3000 MB/S in the cMP. So it doesn't scale well, but it delivers enthusiast class PCIe 3.0 transfer rates to an aging Mac from 2009.
With 2 970 Pro's in RAID0, average Maximum Read speed is 3126 MB/Sec. Average Maximum write speed is 2932 MB/Sec. 970 Pro 1TB average Maximum Read speed is 3071 MB/Sec. Average Maximum write speed is 2622 MB/Sec.
