Best back-up disk for 2020 iMac desktop

Need a backup disk that's compatible with my 2020 iMac desktop running Big Sur OS 11.6. I recently bought a SanDisk Extreme Portable SSD 1TB and the volume is not compatible. Previously, I tried a G-Technology 1TB G-Drive mobile USB-C but it was "fried" when I tried to write data to it. Can anyone recommend a decent back-up disk to run with Time Machine?

iMac 27″, macOS 11.6

Look at the external SSDs from OWC (MacSales.com). You can call Customer Support at OWC and they can suggest the best of their many models for your intended use and budget. I have 8 of their SSDs currently in use. Very reliable, great customer support and warranties.
