Okay I cloned my new Samsung EVO 970 Plus from my OWC Accelsior, High Sierra / BootROM MP51.0089.B00 without a hitch and no firmware update, or newer 140. BootROM. So Samsung must have implemented something new ?I know fusion drives are unpopular here, but I had an idea for how to use one in my 5,1 and I’m curious if anyone has tried It before.
to start, I have a 2010 12 core 3.06ghz 5,1. I just moved my boot disk from a 256gb Apple SSUAX pcie blade (Slot 2) pulled from a 6,1 to a 256gb Samsung SM961 in a kryom.2 evo (slot 3). It’s pretty close to fully saturating the pcie 2.0 bus. I have my home folder striped across 2x2TB ironwolf HDDs in a software raid 0, and that array cloned nightly to a 4TB ultrastar HDD. I use an 8tb ultrastar HDD to store incremental backups of the ssd + raid array in time machine. All the HDDs are in the SATA II drive bays.
the idea I have is to fuse both the Apple SSUAX pcie blade and the 2x2TB RAID 0 array into a single fusion drive that I would use to store my home folder; the idea being that the frequently used library files and other databases could be readily accessible on the SSD, while keeping the 4TB capacity of the raid array that would be extremely expensive to replicate with SSDs.
Is this a terrible idea? I’d have my os & apps on an NVME blade, and as long as I set up the fusion drive properly I should get no worse speeds than my SATA II raid 0 array on its own, with occasional speed boosts from data cached to the SSD, right? I mostly use this machine to manage a large lossless iTunes library and a large adobe Lightroom catalog with lots of RAW files, editing photos in photoshop, editing audio in audacity and adobe audition, and web publishing. Would I be better off just using the SSUAX ssd as a scratch disk for photoshop and audition? I’ve got about 48GB of RAM, and typically only ever get close to using it all when I’ve got 8000 chrome tabs open. Would it make more sense to use 24gb of RAM in a ramdisk for scratch instead, since the files are all temporary anyway? Would it be insane to pull the 4TB ultrastar in favor of 2 more 2TB ironwolf HDDs to mirror + stripe in a 4x2TB raid 10 array, and then fuse THAT with the ssd?
have any of you tried any of this? Thanks in advance for any responses!
The way Apple use the SSD part of the Fusion drive as the write cache for the slow drive rapidly kills any non SLC SSD. Fusion drives are not recommended with any other type of NAND.I know fusion drives are unpopular here, but I had an idea for how to use one in my 5,1 and I’m curious if anyone has tried It before.

Fusion drives work more or less fine with the Apple OEM blades made specifically for Fusion drives since it uses SLC NAND with enormous write tolerance, anything else is just asking for trouble.
Alex is there a gain benefit for updating from BootROM MP51.0089.B00 to BootROM 140.0.0.0.0 considering I have to stay on High Sierra running Pro Tools for now till I can swing a metal card.

You can't, Apple efiflasher checks if you have a METAL supported GPU before flashing the BootROM.Thanks

Yeah I'm new to all this, and I still can't find updating firmware 140. within the High Sierra realm without using a metal card.

Seems you are misunderstanding, SATA and PCIe AHCI are both supported since the first Mac Pro 5,1 firmware, it's PCIe NVMe that started being supported with Sierra (4Kb/sector)/High Sierra(512bytes/sector) for non-bootable disks and bootable only with Mojave firmwares, 140.0.0.0.0+.That's interesting. All this time I've been booting off of a Accelsior (original ), 250meg SSD on Mt. Lion, and a partition of High Sierra with BootROM MP51.0089.B00, how's that possible ?
Every MP51.00xx.B00 BootROM initialise the PCIe slots as PCIe v1.0 by default for everything but the Apple OEM GPUs.Hi everyone,
Since it's my first post on this forum, I hope it's the good place for my question. I've searched a lot without finding the right answer.
According to the recommandations of the first post of this tread, i bought the IO Crest IO-PCE2824-TM2 card adapter, filled it with two blades of NVMe SSD (WD Black SN750) and installed in my MP 5,1.
Everything works fine except that i'm stucked with a speed transfert of about 1500 MB/s instead of the promised 2900 MB/s. You'll find all of the information of my configuration in the attached files.
My only guess is about the boot firmware since I don't have the latest one but the MP51.0089.B00.
I'm waiting for my new graphic card to make the move to Mojave and the 144.0.0.0.0 boot version.
Any thoughts ?
Thanks for yours answers.

Please don't post wrong info. A METAL supported GPU is a requirement for the BootROM upgrade past MP51.0089.B00.Upgrade the bootrom now. You don’t have to upgrade to Mojave to do it, you can keep high Sierra. There are instructions in these forums on how to do this. Good luck!
Thanks for your confirmation. Therefore, I just have to wait for my new graphics card.Every MP51.00xx.B00 BootROM initialise the PCIe slots as PCIe v1.0 by default for everything but the Apple OEM GPUs.
Apple changed it to PCIe v2.0 (5GT/s) as the standard setting only after 138.0.0.0.0 BootROM release.
Thanks, it turned out that for some reason Win10 just hadn't assigned it a drive letter for reasons.Check in Disk Management (diskmgmt.msc) to see if it is marked as offline.
OWC card have a x8 PCIe switch, that limits the maximum bandwidth avaliable to around 2900MB/s with a MP5,1. If you not going to use RAID and will not access more than one blade simultaneously, it will not be much of problem.Would getting the empty internal Accelsior 4M2 and adding 4x970 EVO Plus 2TB yield better performance/ same performance as having them on a PCIe slot each?
I plan to use them as individual drives — no RAID, but I can’t seem to understand clearly the bandwidth limitations of the Accelsior 4M2.
Anyone care to advise?
