On flash, yes. On HDD's, APFS is slower because of file fragmentation. On HDD's also, the fastest volume (HFS) will be the first volume created, the slowest will be the last. On Flash media, it makes no difference.

When creating multiple RAID volumes, do they have the same speed as one big RAID volume in which I create APFS volumes?

There are two ways to do this. I suspect what you want is to create multiple volumes. Just specify the volume size, on each. they are independent this way.

Alternatively since this is APFS by default, you can create one volume, in RAID 0, then use DIsk Utility to create additional volumes. these are APFS volumes, so they share the space on each. It can be confusing, but each volume can use the entire disk, until it cumulatively fills up.

Hi,

I just bought an Express 4M2 box, with 4 NVMe of 2 TB each, to replace old disks. If I set each one individually, the speed will be limited. So I'm thinking about a RAID 0 configuration but I'm not so familiar with that. Can I make a RAID 0 setup with the 4 disks to have a better speed, and the partition them to respect the structure I had with my older disks? Is this the correct way to do it? And how do I do it?

I'm on macOS Ventura, Mac Mini M1

Thanks!
