This post is about disk space and the disk space “consumed” by Windows 7. Disk space is the sort of thing where everyone wants to use less, but the cost of using a bit more relative to the benefits has generally been a posiitve tradeoff. Things have changed recently with the availability of solid-state drives in capacities significantly smaller than the trend in spinning drives. Traditionally most all software, including Windows, would not hesitate to consume a 100MB on a specific (justified) need when looking at a 60GB (or 1,500GB ) drive; with desirable machines shipping with 16GB of solid-state storage, we are looking carefully at the disk space used by Windows—both at setup time and also as a PC “ages”. We also had a specific session at WinHEC on solid-state drives that might be interesting to folks. This post is authored by Michael Beck, a program manager in the core OS deployment feature team.
