Abhi I thought the new operating systems are hungry on processor, RAM and graphics. Can we manage by handling SSD alone ?
If you consider how physical and virtual memory works in most systems, the pagefile (swap in Linux) becomes active just before the physical memory is allocated. In slower SATA based drives, the access speeds are interior owing to moving parts, so this type of virtual memory isn't really useful for high end tasks, but sufficient to keep the system running whilst the volatile memory queue clears. With an SSD drive, the read and write speeds are by far superior, therefore, the system runs at optimal speed regardless of using physical or virtual memory.
