Ideal/Recommended partition


I’m downloading OpenSuse21.1 for 64 bits, now I want to install to get better performance on my system as follows: I have two disks

First one is 120Gb, there I want to get all OS, this hd can be deleted/formated as you recommend.
Second one is 400Gb /dev/sbd Ext4 /home for my work files, actually with my files and I don’t want to lost them.

Please give me best recommended partitions for above configuration, I need to use manual partitioning due I want to conserve my second hd unchanged.

Best regards

Just choose to use entire HD by going like this

The installer will do just as we would recommend
