I'm looking at the Sabrent Rocket NVMe 4.0 SSD in the Ankmax enclosure connected to a Mac

Studio Ultra TB4/USB4 front port vields a maximum read speed of 3,082MB/s and a maximum

write speed of 2,853MB/s. I was going to use 4 x 2TB for 8TB 0 raid and get 12,000MB/s max.

I'm not a Tech person by any stretch and I was wondering if there were any thoughts on this .

TIA

A Raid 0 of 2 disks is 1.5 of it's speed, not twice

3 MB/s is not so fast ; NVME Crucial P5 Plus goes up to 6.6 MB/s reading 5 MB/s writing

4 disks at raid 0 not 2

(two Sabrent dual NVMe enclosures) with a total of four SSDS

running on two TB4 ports in a RAID O. This gives about 6,000 MB/sec read speed.

To calculate the average speed of 4 disk in a raid 0 is not multiplying the disk speed by 4, it is commonly said that you multiply by 1.5 for two. (I had raid 0 of 8 HD  and a raid of 8 x SSD a long time ago)

You mislead me when you wrote "Studio Ultra TB4/USB4 front port vields a maximum read speed of 3,082MB/s and a maximum write speed of 2,853MB/s." what is it ?

Raid 0 is a good solution ! This configuration seems very promising 

If you buy those components on Amazon, you can always send them back if your not happy of the results

I use "BlackMagic Disk test speed" to have the real speed

Understand that you have to have also a lot of memory and it is better to use VI instruments inside your DAW instead going to VE

I am very interested that you publish the result you get with "Blackmagic"

For the moment I am very happy using my MacBook Pro with 64 GB and 4TB internal MVMe, I can play very large orchestration (85 track) if I check that the swap is equal 0
