i think you and i have the same laptop. early 2015 13" retina A1502.I absolutely agree with you. My main idea was to answer the question what is behind 4K LBA when posting the link. For me it doesn't make too much sense to re-formatting it to 4k, mine is running with 512MB sector size in my MacBookPro 13 early 2015, without any issues. Performance is - having MacBook Pro Early "restrictions" in mind - at the maximum level.
likewise, seems its running fine, with whatever sector size it came with. i don't i'll mess with it, with no reward seen on the other side.
so far i've mostly been on linux and sleep / suspension is working A-Okay. i think it worked in windows too but i haven't stressed the disk out in windows to give any meaningful feedback.
this little blue drive is pretty sweet for the price so far : )
