alt Hacker NewsThis is the most useless thing I've seen on here lately. It's not necessary on hard drives, as the page cache did a decent job of improving disk access even in the 90s, let alone with today's fast HDDs. And if you're on an SSD... it'll just burn that out faster.
I love it!
Page caches are nice, but you would see meaningful reduction in load times for the OS and applications by getting data in order on spinning disks. Especially games that used most of your ram and loaded reasonably large level files.
fat seemed particularly prone to spreading files into very small chunks across the disk surface; it's not so big of a deal when fragmented files are made up of large contiguous chunks.
