I have just upgraded iMac 2019 SSD & M.2 NVME….Do I need to create a Fusion Drive?

[M25]

Hi looking for some help. I have upgraded the Sata III and the NVME M.2 on my iMac 2019. I’m not too hot on the software side of things.

I know to installed the macOS and the programs on m.2 and keep sata for files however do I need to create a Fusion Drive or just keep them both separate seeing as they are both SSD?

Any help would be appreciated

The whole point of a Fusion Drive is to take advantage of the faster speed of a small SSD in combination with a slower spinning HD. In other words, if you have 2 SSD's, the there is no point to creating a Fusion Drive and some sources I've read in the past claim that it could actually make things worse

@Rich B22 drops a truth bomb.

Use the 2 drives as "standalone" (NOT fusion) drives.
Things will work better that way.

Thanks…this confirm my suspicions. When installing macOS fresh can I install it using a bootable usb I have created if both SSD are replaced?

Yup. When booted from the USB, use Disk Utility to erase and format the SSD drives. Install macOS onto one of the SSD drives.
