Twice as reliable as raid 0… hahaha.

The main feature is that it’s USB4 instead of TB. Apparently because of the power management between USB and TB, you get 3.1GB/s instead of 2.4GB/s of the same NVMe. And it could work on some systems that have USB4 but not TB, particularly some PCs.
Other than that it would be a lot more boring…
usb4 makes it great as a shuttle drive between different systems too
I just started using the Sabrent Thunderbolt 3 to Dual NVMe M.2 with my Mac Studio as a RAID 1 external disk and its really fast. Working with 4.5k RAW material, no proxies.
It’s nice that we’re getting to the point where storage speeds are all in the “plenty good” territory.
Sort of how game framerates now are like 160fps, despite, you know, humans being unable to discern much more than 60-100fps.
There are gamers that swear by their 240 fps gpu/monitors…

Hi Rufus, are you still using the Thunderbay 4 mini?
I’m searching for a small, mobile setup.
How are you using this disk array? OSX Software Raid 0 or OWC Softraid?
Can you provide any numbers in terms of performance? 
Thanks for your help!
Yeah still using it, although just as a project drive now. I have the Express 4M2 as a Framestore, because I needed more space. How come SSDs don’t seem to be getting any bigger? I was buying 8tb SSDs in 2019 I think, and still that’s the largest size available. I would love to load it up with 4x16tb.
Anyway, yeah it’s good. I stopped using softraid because it has a few issues I didn’t like. So they are both setup with the OSX raid setup. Both have worked seamlessly so far.

Let me know if you need any more info.
Thx for your answer! That helps a lot.
For your 8TB issue… the micron SSDs are available in 16TB, but kinda pricy.

Can you play an EXR sequence 16bit real time 2k with this configuration?
Uncompressed 16bit 2K is about 450 MB/sec, so yes.
