In case anyone is considering testing the IO Crest switch card I contacted a supplier on Alibaba and the sample price for one is $165 plus $30 shipping to the US, plus any customs fees/tariffs, so probably best to just order it under the Syba brand from a domestic supplier.
I just added some colour to the compatibility status. I think this can greatly avoid members misread the poor supported options as the good possible options.
And if anyone just want the good option, can look for the green.
Can you elaborate on that? I'm currently booting Sierra from a Raid 0 created with SoftRAID on a Apricorn Velocity Duo (800MB/s theoretical throughput, 660MB/s actual throughput). I have not updated to High Sierra because I didn't have time to research what APFS would do to my setup.
Super Micro has a x16 PCIe switch card model AOC-SLG3-8E2P. I can't seem to find it anywhere though. They list it here: https://www.supermicro.com/products/nfo/storage_cards.cfm

How about this 4 blade for $169 due to be released in October. https://store.mineority.io/sqrl/acorn-nest-x4/
I can't see a PLX switch on their board diagram.
From their webpage : " AcornNest X4 allows you to host four Acorn units in a PCIe 2.0/3.0 x16 or PCIe 3.0 x8 slot without any special motherboard requirements."
birfucation ?
I found this in post #485 https://bitcointalk.org/index.php?topic=4391318.480
" The Nest X4 has a PCIe switch so it eliminates the need for the MB to support bifurcation to share the power of the acorns."
I wonder .. . .

Yes, yet they state USB 2.0 or USB 3.0 + Link width X16 .. and . . if there is no switch onboard only the first blade of possible 4 will be viable AFAIK.
The Syba 2 blade Is .. I quote " DEDICATED USB 3.0. I assume that USB 3.0 is backwards compatible .. . is this true when the word "DEDICATED" is used in the product description ?
Depending on the PLX or ASMEDIA SWITCH being aboard the $169 price is certainly attractive.
( They also have a 2 blade adapter which supposedly has onboard bifurcation )

Ok, who’s going to be the first to guinea pig an Optane SSD... 
I see it listed at $149.99 and there’s a 2 M.2 version for $129.99. I sent them an email to ask about the switch.
I have a spare supermicro x16 switch available. It was used once and successfully managed to electrically fry the x58 chipset on a 4,1 cpu tray.
WOW ! Thanks for that info !
Can you tell us more about that ( painful ) experience ? What do you think caused it ?
What else was in the PCIe slots when the 'FRY'occurred ?
They no longer list that model in their "Downloads/manuals 'list

Supermicro sounds like a wonderfully competent company:

Thanks for the reminder. I also have an efi modded 680 gtx that stays in high speed fan mode at all times due to the super micro card. The apple 1tb ssuax I had at that time survived with all data and no harm.
Don’t be in a rush to buy a new SSD. Prices expected to decline into next year.

I think this scenario can be possible, but honestly, it's one of that things that you can do but shouldn't.
Think about how much points of failure you have.
I definitely wouldn't do it.
In case anyone is interested, I couldn't get this to work either re-seating or in the kyro adapter.
I returned it and replaced it with a 970 Evo which works fine (Even though it's also based on a PM981 controller).
I don't know if there was a problem with the individual original drive or a problem with the specific model, but either way the 970 is working fine.
i can confirmed the "IO Crest IO-PCE2824-TM2" two blade card work with 4,1/5,1

Good speed?
If 3000 MB/s is good from your perspective, it's twice the maximum speed of a traditional PCIe 2.0 m.2 adapter.
The ASM8424 chipset, at the heart of the I/O Crest solution, supports an electrical x8 connection, with a maximum throughput of ~ 3000 MB/s.
Alex,
Off topic... but you've been so helpful to everyone... FYI - I notice you have some "ghosting" around your fonts. I had the same strange colors when I stuck in my RX580 yesterday. Turning off LCD font smoothing in Sys Prefs>General got rid of that for me if it's bugging you.
