Virtual Memory: SSD vs HDD
| Aspect | Virtual Memory on SSD | Virtual Memory on HDD |
|---|---|---|
| Speed Impact | Noticeable slowdown but tolerable (10-50ms delay) | Severe slowdown (100-500ms+ delay) |
| User Experience | Programs stutter briefly when swapping | Programs freeze for several seconds |
| Thrashing | Can handle moderate paging before thrashing | Thrashes quickly with heavy swapping |
| Wear Concern | Older SSDs have limited write cycles (modern SSDs handle it fine) | HDDs can handle unlimited writes |
| Best Use | Emergency backup when RAM temporarily full | Only for basic tasks (web browsing, documents) |
