Btrfs Memes

You just unboxed your shiny new 1TB SSD, formatted it with btrfs like a proper Linux enthusiast, and suddenly you're staring at 0.73 TiB of usable space. The guy in the painting? That's you, pointing accusingly at the manufacturer like they personally robbed you of 270 GB. Here's the thing: manufacturers count in decimal (1 TB = 1,000,000,000,000 bytes) while your OS counts in binary (1 TiB = 1,099,511,627,776 bytes). Add in filesystem overhead, and boom—your "1 TB" drive is actually 0.91 TiB before formatting, then drops to 0.73 TiB after. It's technically not a scam, but it sure feels like one when you're trying to install yet another 200GB game. Marketing departments have been pulling this move since floppy disks, and we still fall for it every single time.
