As someone who has always been cautious about SSD writes (possibly overcautious/ paranoid? Idk, some seem to think it's not a concern with modern SSDs. But I haven't really spent any time researching recently.) I always like to have a hard disk as well as an SSD and I put my writeback device and any swap partitions there.
Sorry this probably isn't a helpful answer.
No it's actually worse than superfluous commas, and the author is using them where things like periods ought to be. The author does not actually understand how use sentences properly.
