Impacts general system efficiency and quickness. Moving within the OS, launching native Windows programs, and other tasks gain advantages from the SSD's performance.
I noticed a noticeable improvement in overall responsiveness and faster load times when switching from a traditional hard drive to an SSD, and again when moving to an M.2 NVMe drive as the boot disk. For gaming, benchmarks, or rendering tasks, there’s only minimal change since the system handles data quickly regardless of read speed or caching. That said, the jump in responsiveness is substantial—especially after switching from HDD to SSD. It really enhances the experience, even if it doesn’t affect FPS much. The game loads almost instantly now, like in Fallout 4, which makes playing more enjoyable. Windows also feels and reacts much faster overall. Results depend on the type of SSD you choose and its specifications, but it’s safe to say any SSD will outperform an HDD in read/write speed and IOPS.
Could having only the operating system installed affect performance or functionality?
There is some indication that bigger SSDs tend to perform slightly better, while having more data stored on an SSD can cause slower speeds but only in small ways overall. So I wouldn’t say it’s a big deal. If everything stays the same except the drive type, the speed depends mainly on two factors: 1. How fast the drive reads and writes and its IOPS performance 2. The system’s workload—like background processes or active tasks. Even if your apps or files are still idle, they won’t impact results unless they’re being used. That said, switching from a HDD to an SSD usually boosts responsiveness and reduces load times for any setup.
