Samsung said its 256-gigabyte solid state drive (SSD) for data storage is 2.4 times faster than traditional hard drives. To me this just emphasizes how advanced traditional HDDs are. I would've expected a bigger increase in speed. Then again, I'm not sure how significant a single number is (random access, small files, large files, seek time...)
