看和WD6000HLHX 是单盘200的~~
就是
VelociRaptor VR200M，SATA3接口 32缓存

而上一代VelociRaptor则被称为VelociRaptor VR150M 就是WD150HLFS和 WD3000HLFS~

SATA2接口~ 16M缓存

那WD4500HLHX 单盘多少？貌似是sata3接口的~

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second.
