HDD vs SDD - QuickBench 4 benchmarking
Here's the results of tests I ran today using QuickBench 4 from SpeedTools.com:
Small Random READ 4K - 1024K
HDD 80G = 9MB/s
SDD 64G = 35MB/s *
Small Random WRITE 4K - 1024K
HDD 80G = 11MB/s
SDD 64G = 16MB/s *
Small Sequential READ 4K - 1024K
HDD 80G = 40MB/s *
SDD 64G = 35MB/s
Small Sequential WRITE 4K - 1024K
HDD 80G = 30MB/s *
SDD 64G = 18MB/s
Medium Sustained READ (2MB - 10MB)
HDD 80G = 39MB/s
SDD 64G = 50MB/s *
Medium Sustained WRITE (2MB - 10MB)
HDD 80G = 41MB/s *
SDD 64G = 24MB/s
Large Sustained READ (20MB - 100MB)
HDD 80G = 35MB/s
SDD 64G = 51MB/s *
Large Sustained WRITE (20MB - 100MB)
HDD 80G = 35MB/s *
SDD 64G = 29MB/s
(* means fastest of the two for a given test)
I posted the graphs and analysis here:

BOTTOMLINE: The SSD does small random read/write faster than any existing notebook drive. That's why it boots fast, launches fasts, and wakes fast. Haven't tested it but I bet it does Photoshop scratch disk and virtual memory more efficiently as well.
