Weird thing, you don't tin pads if you not going to install anything on them, maybe was installed and removed?
Well it’s good to know it’s a rare cpu tray. The serial number looks to be in the same format as my original 2009, an almost identical configuration except it came with 3x1gb ram vs 3x2gb.
It would be nice if it does. Granted, there's already a way to get NVMe SSDs to boot within a classic Mac Pro—but, of course, it's unorthodox.
Yeah, it works fine. I injected the NVMe driver payload shortly after making that post. So far it’s working flawlessly. Many others are also using 138/NVMe as well.

That’s some awfully slow write speed. I guess RAID 0 would just be good if you need faster read.
10.6 don't have TRIM and it's a mirror/RAID1, the interesting thing is more than 1500 read speed.
Edit: Incorrect info, Apple enabled TRIM for Apple SSDs with 10.6.8 update.

Yeah, I definitely have a problem going on there w/ the write speed. But as Alexandre points out, the cool part is the Read speed approaching 2x the single SSD (1400-1500MB/s). As he also points out, this is actually a RAID1 mirror (which is probably what you meant)...so while the write speed, when not fouled up like this, will be approx 1x of a single SSD, since the same thing is written in tandem to both SSDs; but the read speed can function like a RAID0 and get nearly 2x that of a single SSD.
So, while we're at it, any suggestions on what to do regarding that write perf? I know I know...OT.
Snow leopard (10.6.8) does have TRIM however on non Apple SSDs you generally have to use a 3rd party application to enable it/patch the kext responsible for it.
once TRIM is enabled its a good idea to run fsck -fy in Single user mode to force OS X to trim unused blocks. this can help recover disk speed on an SSD thats been run without trim for a long time (note this dosent work if the disk is APFS formatted)
These are SSUBX blades, so Samsung/Apple. Just re-checked, and they do in fact show TRIM Support status of "Yes" in System Profiler. Is there anything I can try remotely, since I don't have hands on the machine (to go into Single User mode) right now?
Yep, I was wrong about TRIM. Apple quietly enabled TRIM for Apple SSDs with 10.6.8 update.
heres a couple Stock BootROM dumps of my Xserve1,1 and MP2,1 (its a flashed 1,1), from my Microcode shenanigans
Added to the stash. It's half the size of 4,1/5,1 ones, but seems the same basic structure. Thx!
If that's a test drive, you may un-RAID them now, and just to check if the writing performance still the same. If yes, then may be TRIM is activated on 10.6.8, but not be used in RAID.
yeah pre MCP79 Macs have 2MB BootROMs (with the MP/XS using an EEPROM thats similar to the one used in NWR PowerPC Macs while everything else AFAIK uses a regular 8 pin SPI device)
(new world ROM PowerPC macs have 1MB parallel BootROMs)
it would be interesting to see where the CSM part of a BootROM is stored at and then have a look at the same place on the Xserve BR, as the Xserve (or at least on the surfice) dosent have a CSM and cant boot/Load Non EFI OSs/OptionROMs
Dual and Quad cards from QNAP leveraging the ASMedia Chipset in PCIe 2.0 and PCIe 3.0 configurations are compatible with Windows & Linux. With that in mind, they should be compatible with Mac OS.
From what I remember, the QNAP low cost PCIe SSD adapters are offered adapters with two M.2 slots. running at x4 that would have a max transfer rate of 1500 MB/Sec selling for $110ish. As well as adapters with 4 M.2 slots running at x8 that should max out at 3000 MB/sec - starting at $200 for a PCIe 2.x and up to $269 for PCIe 3.0.

Did Apple add bitruification support without having to use a PLX? Now that would be a game changer.

How did you install it though? Via the built-in update mechanism or did you download the full installer? At least in the past, fw updates are only available in the full installer.No new Bootrom update for me with this Beta
I realised I started the install of the Public Beta, not the DP. It was the full installer though. DP9 may still have a Bootrom update. I don't know
