People who read from disks and people who write to them. How SSDs organize data definitely had read and write performance implications and if you're writing to disk, some write habits that are perfectly reasonable on regular disks can cause catastrophically fast wear on SSDs.
- KennyBlanken 4y agoYes, but the number of people who need to be worried about aligning their writes and such is pretty small; certainly not "every" programmer. The author gets into the weeds about certain things application level programmers almost never need to know or concern themselves about. He really doesn't understand what's useful information and what isn't. If you're programming at enterprise scale, this sort of stuff is the responsibility of architect-level programmers and senior systems engineers. Even most linux sysadmins know all about block alignment (well, if they predate most of the various tools figuring out block size/alignment stuff for you.) It's nothing new - RAID arrays work best when properly aligned, for example.
