That’s interesting. Will try that later today. Not in a position to remove all the cards at the moment.

Out of curiosity, how did people determine that? I don’t see that info anywhere on the spec sheet.

Much appreciated.

Since some people with the top WD Black had trouble getting it to work past 750MB/s, maybe the blade firmware has a problem when in a PCIe 2.0 slot - this will only be confirmed if someone with a Highpoint SSD7101A/Amfeltec Squid 3.0 could test one of these blades.
 
tsialex I wonder if you can answer this please with SSD7101A and Samsung 970 EVO 2TB drive formatted to APFS trim on My Speeds were (1st image)But formatted to MacOS extended Journaled its now this (2nd image)

Thanks for that. The Samsung Spec sheet basically says the same thing that you highlighted and people had better results with that blade. NVMe M2 is basically the Wild West on Mac at this stage. User testing and forums like this provide the only decent info available. Its much appreciated. I’ll report back when I have a chance to remove the cards, but your explanation seems more likely.

I'm the wrong person to answer this, I never did comparative tests of HFS+/APFS and I don't know about any overhead that APFS could have over HFS+.

Btw, unless you boot from another drive and don't have Spotlight indexing enabled for the drive that you are benchmarking, you can't compare benchmarks.

I’m running one of those in my Mac Pro at x4 PCIe 2.0 speeds, I have it in slot 2 though. I get about ~1450MB/s read and write. Maybe their eSata card is eating up half the bandwidth on slots 3 and 4?

Honestly, I don't believe any manufacturer spec sheet. When I'm buying something I try to find people with the same hardware config that I'm going to use the blade for.

Various manufacturers were found to use misleading spec sheets or dirty tricks like using the same name for totally different products after the reviews were published, so beware.

It's the exact same one? WD Black line has at least 2 major revisions and various minor ones.

Hmmm. That’s interesting also. Could also be that Amazon sent me older stock. No discernible date on the package, however.

The first thing is to remove all other PCIe cards, install into PCIe slot-2 and do a zap-PRAM.

After that, if the throughput still is around 750MB/s, try to exchange it to a more Mac Pro compatible blade, like Samsung 970EVO and others tested here - check the first post.

Problem solved. Put the PX1 in slot 2 and its running at the expected speed. 1427 write/1497 read.

Note: Had to zap PRAM 3 times before it would boot. Not sure what’s up with that, but it seems fine now.

Thank you TheIguana and TsiAlex for helping get to the bottom of this.
 
People are buying it cheaper from AliBaba, not AliExpress.

I pulled the trigger on exactly this I/O Crest card, an MSI VEGA 64 reference card and the Pixlas Mod cable from ModDIY.com

I will report back once I have a better benchmark compared to the PX1 and the HyperX Pred. single slot adapter.
 
^^^Since I bought my I/O Crest card the Alibaba price has increased from $169. to $199. The final price on my invoice with shipping and processing fee was $188.68. With the $30 increase that would make it at least $219. BTW, my card is in transit. It was held up at the vendor until I sent them a couple of eMails.

I really don't like doing business with the Chinese.

Just for the record, the one I am running was: WDS100T2X0C. Ergo should be the same one he listed.
 
I have just received the Iocrest. Card not recognized by the Mac Pro 5.1. It doesnt appears in the PCI System Information.

The fan running


Any help?

Thanks
 
EDIT : Which PCIe slot is it in ?

1. Reset the blade ? = Shut down, take it out and put it back in again

2. PRAM reset - wait for the CHIME 4 times? ( Do this anyway. )

3. Remove ALL other PCIe cards ( except GPU ) shutdown - cold re-start.

4. Possibly also remove the GPU ! Just do a cold boot with the IOcrest installed.
Then put the GPU back in and check to see if the IOcrest is listed.

I used 3. to get my 4,1>5,1 to recognise my HD 7950's 5 GT/s PCIE Link Speed as being x 16. Might work to get the IOcrest seen correctly

5. Defective IOcrest ? ask for a replacement.

Good luck many here are eager to hear your results.

with a 100 more, you can buy the new SSD7102, which is bootable in Mac and windows, I already tested the card on w10 on my hackintosh and is raid0 bootable with 4 Samsung 970 pro hitting almost 12 gbps, I ordered another card which should arrive as soon as stock becomes available, I also order some custom made backplates to cover that ugly green PCB, the only problem is that since the card is in pre sale, we still don't have Mac OS kext drivers or the app to make a raid0 bootable on Mac os, the card is recognized by default on Mojave but I can only make a raid0 using disk utility, yes it does boot in my hackintosh but I can only use the raid0 on HFS+ since raid0 is not bootable using APFS unless the person do some crazy steps , that I know about but I honestly don't have time for that crazy stuff

been there done that

to not complicated thing too much, the card boots in EUFI mode, what I plan on doing is this

when high point releases the kexts drivers for Mac
I plan on creating a raid0 array on APFS using high point app
yes you read that right APFS + RAID0 bootable

why? because the card creates a single logical drives that can be formatted as APFS and it will be treat it like a regular single drive

that means that it will create the preboot partition and recovery partition
just like any regular single drive
so Mac OS can be install in raid0 and boot from the card
remember the card is bootable, high point integrated the booting capabilities in the card firmware

the problem is that I need the kext drivers to be able to do this

I had SSD7101 so I know what I'm talking about
it is exactly the same behavior with SSD7102
before high point released the kext drivers for SSD7101 I had the same problem that I have now with SSD7102

why? because I still don't have the kext drivers for SSD7102

if you don't use high point drivers then Mac OS will not see the raid as a single logical volume
Mac OS will be able to recognized the card using Mac OS generic integrated drivers
you will be able to create a raid array but you won't be able to create a single logical drive because you need high point drivers to be able to do that

and without creating a single logical drive then card won't be bootable on Mac OS using APFS

with out high point driver, Mac OS will only see all the drives as separates individual drives
not as only one single drive

there is a big difference when you create a raid0 array using disk utility
vs
creating a raid0 array using the web guide app

disk utility uses the old way that creates boot osx partitions then you won't have the recovery partition or the preboot partitions using disk utility to create the raid0 array

but when you use the web guide app, after creating the raid0 array then Mac OS will only see the drive as a single drive, and if you format the raid0, Mac OS will see the raid0 drive as a single drive and it will create all those partitions for you and the raid0 volume will be bootable in APFS

hope I didn't complicate things

Thank you SO MUCH for the extense information, Gogete. Much appreciated. So you are telling me that you can boot Mojave
from a SSD7101 in that non standard raid ? Sounds rare. Whata about Safebot? Or boot to the recovery petition?
[doublepost=1545324877][/doublepost]Just one question. How fast is supposed to be a single NVMe Evo 970 with the Iocrest. It goes at the same speed as with just a riser, 1.500GB/seg in Slot 2
[doublepost=1545324972][/doublepost]

MIne has arrived today. Maximun 1500GB/seg with an EVO 970. Dont understand. Slot 2

When I ordered mine they said there were no Mac drivers available yet so they canceled my order and said they will let me know when they become available. Can you confirm you can boot the drives in the cMP in HS or Mojave?
 
I am talking about 7102
exactly this is the new SSD7102 not SSD7101 which is not bootable
they told me that they "high point" will release Mac OS drivers at the 1st quarter of 2019
the same thing happened with SSD7101, i had one SSD7101 and when I was going to order the 2nd one
I discovered the new SSD7102 which is better than the previous SSD7101 because the new SSD7102 is bootable

so I sold my SSD7101 and bought the new SSD7102
I ordered the 2nd card yesterday

I have 8 samsung 970 pro

yes the card is working right now in Mojave with without the need to install any driver
if you look in Library/ Extensions
you are going to see these two files

HighPointIOP.kext
HighPointRR.kext

those 2 files are included in Mac OS Mojave by default
the only difference is what I already explained
I'm sure you will be able to boot your M.2 drive using the multi boot option
to do bootable raid0, it has to be in HFS+ for now

you can do APFS raid0 but as data only, not bootable

unfortunately I can't confirmed about Mac models because I have a Hackintosh, not a real
Mac but I'm sure the card will work as long as the mac you have has a 16x pci-e 3.0 for maximum performance

I'm not sure if the Mac Pro 5.1 has pci-e 3.0 slots, I think they only have pci-e 2.0 but I'm not sure
if that is the case then that will create a bottle neck because is like running a pci-e 3.0 at 8x

they said the same thing about the SSD7101 and I manage to make the unbootable card bootable on Mac OS using clover boot loader , simply by installing the EFI folder in one of the boot osx partitions

I know real Macs are a totally different story but is really up to you
but the card is advertise to work on Mac OS, just like the previous card and they did release the drivers right on time
is just that they don't have the drivers right now to let you use the web gui app to create the raid volume the right way

it all depends on the number of drivers you have and what you are planing to do
you can install Mac OS on a single drive and use all the others drives individually until they release the drivers for Mac OS

you can do raid using disk utility but I'm not sure if it will be bootable on a Mac without high point drivers

I honestly don't like guessing when is not my money on the line
like a said is up to you

the card works on my system not because is a pc or a hackintosh
the card works because it has the default drivers already integrated on Mac OS mojave

but you will have some limited support until high point releases their drivers that are specially made or designed for that card

hope you understand my English

at 16 pci-e 2.0 the most you can get out the card is 6000 read and 6000 write
that is like running the card at 8x 3.0

I'm sure if you use the card in none raid mode just for the time being
until HP releases the proper drivers
you will be able to boot Mac OS Mojave or HS

I'm sorry I don't have a real Mac to run a test for you

Hare are what shown in the System Information. Anyone can tell me if it´s correct. Evo 970 at maximum 1500MB/s read/write at Slot 2
x4 is correct?

I can see that with the Iocrest other people gets the right speed. I really don´t undestand.

Thanks

So x16 it´s the correct link speed. Now I can see why mine only gets 1.500MB/s. Probably i will send back the card. No improvement this way.

Well This is odd. Tried what Mikx told me. Booted without the graphic card, and evrything is as supposed to be.

iocrest single.png




But when I connect the tge gaphic card again, comes back to 1500MB/s read/write.
 
*******

Which PCIe slot is the IOCREST in ? Slot 1 or slot 2 ?
( I did ask that . . . . :) it may be relevant. . no idea here as I don't have one yet. )
