MP 1,1-5,1 Big Sur and Raid 0

[0488568]

Hello,

Can anyone confirm if they have RAID 0 working with an external drive in Big Sur?

Just found this:

Create a disk set using Disk Utility on Mac

Use Disk Utility on your Mac to create a RAID set to optimize storage performance and protect your data.

support.apple.com

And it seems Big Sur brings back support for RAID 0.

I have a sonnet card with 2 SSD and would like to install Big Sur.

Thanks!

Nothing changed, still non-bootable only:

• Striped (RAID 0) set: A striped RAID set can speed up access to your data. You can’t create a RAID set on your startup disk; you must first start up your computer from another disk.
• Mirrored (RAID 1) set: Protect your data against hardware failure with a mirrored RAID set. When you create a mirrored RAID set, your data is written to multiple disks so the information is stored redundantly. You can’t create a RAID set on your startup disk; you must first start up your computer from another disk.

Hi,

Do you know of a working tutorial to get 2 external ssd (sonnet pci card) formatted to APFS and RAID 0?

I tried this with Catalina and was not able to get it working. Thats why im still with Mojave.

If not, what would you recommend for a nvme boot up solution?

Thank you.

Seems you didn't understood the real problem, it has nothing to do with internal vs external.

Apple only supported bootable arrays with HFS+ and never supported it with APFS, so 10.13.6 is the last macOS release that can boot from an array officially. You can make an ugly hack to make it work with Mojave, but you have to clone your boot disk to one disk and then do the updates there and clone back to the array, but this is an insane amount of work with the sheer number of updates being released lately. Use your array for data/storage/scratch disk.

NVMe adds a lot of boot time, the throughput from high end blades is insane when you compare with SATA2, but takes a minute more to boot since all PCIe space need to be detected/enumerated. Another thing, boot drives most of the time access disk with 4k transfers, NVMe blades don't improve it dramatically unless you spend a lot.

Read the first post of the PCIe SSD thread to see what work or don't:

PCIe SSDs - NVMe & AHCI

This is a general info thread for blade SSDs that can be used in the Mac Pro. This is a WikiPost so anyone with the proper credentials may edit it. NVMe SSDs can be used as a boot drive in the MP5,1 and MP6,1 with the latest firmware installed (beginning with version 140.0.0.0.0 for MP5,1 and...

So what are my options? Longer boot up with nvme but better performance. Or boot with only one drive formatted with APFS in my sonnet?

Basically, yes.

I can’t remember where I saw the post, but I followed difficult directions & installed Catalina to a Raid0 w/ terminal commands to set it up & dosdudes patcher to install Catalina because super duper disk clones did not work. I have raid0 w/ 2 x 250GB ssd’s and over 500 on the black magic disk speed test

You saw it Here ... This is indeed an AMAZING write-up that just works ... I followed it a few months ago and created a RAID-0 With 3 NVME Adata Gammix S50 on a hackintosh and it is insanely fast... I get read speeds of 8600 ... The funny thing is that I cannot do it again... The reason ? For some really insane and obscure reason... When you create an installer with createinstallmedia command from Apple and put your EFI there it boots perfectly... But in order for this hack with RAID 0 to work you need at the FINAL STAGE to BOOT from Dosdude's Catalina Patcher to perform APFS Patch AND SIP Patch.. but the last 2 months I can't boot when I create the installer with Catalina Dosdude Patcher... So I cant do it again on my new rig and this is so funny ! Other people state that they cant boot even on a real unsupported catalina mac after 10.15.5.... so there are issues with the patcher actually..I even tried 10.15.4 and older but it still does not boot ! Does anyone know if you can apply the dosdude patches on a drive without BOOTING from the installer ? Thanks ! Maybe the new big sur patcher will let us do it AGAIN ! Its so refreshing and helpful when you get these speeds !!! Raid 4 ever !

Come on Community..pls help Generic_bug and myself get Big Sur running on RAID0 (for speed) Generic_bug are You BS'ing 8600 read speeds !? THAT'S What I want !!! I have Big Sur running good on 3 of my Macs. 2 of my Mac Pro's I used https://create.pro/opencore-catalina-install-guide/ and the Video.. On 1 of my Mac Mini's I used

.. If I better understood OpenCore I think I could do the RAID0 But it's a bit over my head...With all the Big Sur Patches out there I really wish DOSDUDE1 did 1. His worked good & were Easy...

Can anyone tell me if this still works, or am I getting to old to do VooDoo Magic on my MP’s ? I did it ok 2 X , but since it won’t update I tried it again & this time I could NOT get it to work. Does it work on Big Sur ? Should I be putting Big Sur on a NVMe, a SSD in a Tray, a SSD on a PCIe (sata 6 ) adapter or RAID0 for performance ? I am now using OC but I see Big Mac patch, Patched Sur and other confusing stuff. ?? I concidder my self a Mac Pro expert but I am no “TSIALEX’ or Martin Lo” Man I miss the DOSDUDE1 Patches…they were easy & just Worked…

The only way I managed to make RAID-0 work was using macOS Catalina, was through micropatcher.sh

Maybe it works with macOS Big Sur and Monterey.

Hi wegg3, how did you make your RAID array. With this commands ?

diskutil unmountDisk disk0
diskutil unmountDisk disk1
gpt destroy /dev/disk0
gpt destroy /dev/disk1
diskutil appleRAID create stripe Storage JHFS+ disk0 disk1
diskutil unmountDisk disk2
gpt create disk2
gpt add -t hfs disk2

Sorry to bother you, but could you elaborate on how you were able to boot Big Sur from a RAID array using micropatcher.sh?

Sorry, it only worked on Catalina.

 

[edulterado]

Is there any successful experience installing Big Sur on a bootable RAID 0 with an unsupported mac?

I've tried with both OCLP and micropatcher, all to no avail.
