Personally, I disagree about the notion that a few gigabytes are tiny, even on modern desktops/laptops. I’d love to have that extra space on my laptop, as I’m running short right now. I realize there are multi-terabyte drives out there, but how many “modern computer” users actually have one? Let us not forget the fact that SSDs, which being considered by many, tend to have lower capacities than hard drives. On top of that, many of the most popular commercial programs are starting to consume more and more disk space (typically without adding any real features) with each new version, presumably to add more anti-user code. Likewise for videos, since after all we really need 4k, so that someday we can “really need” 8k. Of course, if Microsoft really wanted to consume less of their users’ disk space, they would probably find ways of making the system use less space in the first place.
But… how much do you want to bet this compression is simply LZ77, the [B]EXACT SAME[/B] transparent compression that even low-end computers have been able to use with ease for years? If so, why are there any system requirements at all? I’ve seen computers from the late 1990’s/early 2000’s that could read/write compressed files with very little difference in RAM/CPU usage. I always advise people using NTFS to compress as much as possible (while being careful not to compress the bootloader, which cannot function when compressed), so as to decrease HDD access times and increase the amount of free space.
