Is there an audible difference streaming files from a NAS compared to build in SSD?

Both SSDs and hard drives do the same job: They boot your system, and store your applications and personal files. But each type of storage has its own unique feature set.
Hard drives win on price and capacity. SSDs work best if speed, ruggedness, form factor, noise, or fragmentation (technically, a subset of speed) are important factors to you. If it weren't for the price and capacity issues, SSDs would be the hands-down winner.
