MP All Models PCIe SSDs - NVMe & AHCI

[basslik]

No, I still have the I/O crest card as well. The Crest card is real great, but the heatsink is larger. When in slot#2 it obstructs airflow to the GPU. The Ablecom card is a lot shorter and slimmer and let’s air flow to the GPU. It’s not an issue any more since I have the Vega Pro, but it was a problem when I still had the 580 in there. Since The MP is my main archive computer, I have all PCIe slots filled with fast ssd blades.
The crest has two older AHCI blades, the others have NVME blades. I threw out all usb adapter cards unfortunately.

Mine has been in slot 2 since day one. I say around four years. Never had any heat issues whatsoever. Running high tracks counts, with many CPU intense plugins, and never got overheated.

Plus you take a hit if you are not using the x16 lanes with two Nvme's in it, if running RAID, reduced speed.

There's enough flow for sure though.

I imagine doing video would be a heat concern though.

Just ordered a SM951 MZHPV256HDGL AHCI for my mac pro 1,1/1,2. Bought some cheap PCI-NVME adapters some time ago and let's hope they can do AHCI SATA SSD but will find out. Have a link to another cheap PCIe to AHCI that does work according to reddit post but first i'll check the online specs of the ones i already have.

GLOTRENDS PA20 2 Ports M.2 NVMe to PCIe 3.0 X4 Adapter with PCIe Bifurcation Function, Support 22110/2280/2260/2242/2230 Size, Support Soft RAID​

anyone tried this one? There is one review on german amazon that says it works perfectly on 5,1 and even boots Mojave. Seems like a good alternative to buying a used I/O Crest dual card? If I had a usecase for having M2 storage on a cMP5,1 I would buy one

From Amazon listing seems that Glotrends PA20 is a ASM2812 based card, should work, but with no performance gains since is a x4 upstream switch.

No, since is a x4 card the performance will be around 1450MB/s and is only useful for installing two M.2 NVMe blades to one slot.

Do not buy this card thinking that you gonna have PCIe 3 performance with a MacPro5,1, again, this card is just a way to use two NVMe blades with the x4 Mac Pro slot.

oh yeah i always forget that 5,1 has PCIe 2.0 lol. the performance gains are pretty minimal then. Thanks for reminding me

No, no performance gains whatsoever.

hm but isn't 1450 MB/s over 50% faster than a SATA SSD in a 5,1 (which is around 600 MB/s)?

You can use a $3 M.2 single adapter from AliExpress and have the exact same 1450MB/s.

Btw, edit your post and remove the fast storage or someone will probably read only your post and buy the card.

 

[tsialex]

SATA SSD in a 5,1 (which is around 600 MB/s)?

MacPro3,1/4,1/5,1 SATA controllers are SATA II (also called SATA 300) and limited to up to ~250MB/s sustained throughput.

now I have a 500mb/s sata mx500 ssd, I would like to buy a pcie card for an m.2 even just to go double the speed, but I didn't want to spend a crazy amount of maximum €50 on Amazon... any advice?

I would like to install mojave on m.2 and then update with oclp to osx 14 or 15 and then boot from there

You'll need to metal card to update to Mojave.

As Alex statedd, Sata will not give you the 500MB speed though.

PCIe will certainly quadruple the Sata speed.

Can't go wrong with the Samsung EVO 970.

yes I already have an rx 580 card and crucial ssd hd, I just wanted to upgrade to m.2 on pcie, but without spending a fortune

I suggest a OWC Accelsior PCIe. Pretty cheap, and rock solid.
OWC Accelsior 1A
The Accelsior 4M2 if you wanted to take full advantage of slot2. But there's cheaper cards out there for that purpose.

Oggi ho ricevuto questo adattatore Glotrends NVMe PCIe 4.0 x4 con dissipatore di calore.

Non sono sicuro di quale modello M.2 acquistare:
Samsung 990 PRO (nuovo)
WD Black SN850X (nuovo)

Crucial P5 Plus (usato)
Samsung 970 Evo Plus (usato)

 

[Mad Kat]

Another question, should I prepare the m.2 by initializing in Apfs and then with ccc I copy from the hd that I still have or repeat the steps, installing mojave and then with oclp I move to macos 13/14/15 (I still have to decide which one)

Hey guys! 👋
Sorry to interject...

Now, I don't know if somewhere in those previous 152 pages (O___O) of comments there's already an answer to this question/issue...

But I have a 2013 Mac Pro, and I wanted to upgrade the SSD, so I went with a KIOXIA XG6 one, because this info. looked very promising:

Now, long story short: it does in fact 'work'...

-BUT, there is one annoying issue: I cannot sleep my computer for more than, say, 5hrs. If I do, when I click or press a key to wake-up my computer, the screen is gray, and pixelated/jumbled. The only way to get it to work again is by holding the power-button, shutting it off, and restarting it.

Moreover, if the computer has been shut off for 5+hrs (overnight, say), I can't just hit the power-button once to turn it on. Doing so just leads to a folder and ? icon, as though the SSD isn't even recognized yet. So what I have to do is press the power-button once, wait 2 seconds (-almost like giving it an initial 'charge' to come back to life (....?)), then hold the power-button until start-up is force-canceled, then hit the power-button again, this time letting it start-up like normal, which it totally, reliably does at that point.
...
That is the dumb 'ritual' I have to do every morning before starting my work... -___-

So, anyone out there care to opine on what might be happening here?
-Anyone heard of this happening in other circumstances?
-Any known solutions?

It's worth noting that this does NOT happen (i.e. the computer can sleep and wake 100% normally, etc.) when I use the original, Apple-made SSD (256GB) it came with.


Anyway, thanks for any help/ideas/leads! 😁👍

~Cheers!
