I was just playing around with Solus in a VM to see how it defaulted it partition setup (using the Plasma Testing ISO). What I noticed is that the installer doesn't follow modern best practices, and it will result in a partition layout that will hurt SSD performance and lifetimes. SSD partitions and modern 4K HDD should always have their sectors 4KiB aligned.
GParted, KDE Partition Manager, and Windows utilities default to aligning partitions to 2048 sectors (512 B/sec = 1 MiB boundaries). 1 MiB alignment will always be 4KiB aligned as well as for any potential issues with flash erase block sizes (which are higher than 4K).
I did an install from UEFI with ext4, and let it pick swap space, it resulted in this EFI partition
|Partition||Start Sector||End Sector||Size||Size (MiB)||4KiB Aligned||1 MiB Aligned|
The EFI partition is 4KiB aligned, but it doesn't match the default used for other programs. For some reason, the installer is leaving a 32 sector gap between the partitions, which then leaves all subsequent partitions misaligned. It would probably be better to just align all partitions to the 2048 sector/1MiB boundary.
