External Hard Drives - Why not SATA-2?

  villageidiot 22:48 19 Mar 2007

Question - My understanding is that USB 2.0 runs at 480Mb/s, and SATA-2 HDDs run at 3000MB/s (3Gb/s), i.e. six times faster. So why isn't a SATA-2 port put on the back of computers, for external HDDs to use?

Philosophising - What will happen when solid state 10GB+ HDDs get going? Will DRAM, HDDs, and solid state storage all merge into one for the first 10GB of storage for most computers?

I think they do make Sata External's but it works through the USB so it runs as the same speed

Many new mobo are just now starting to have e-sata ports, this should improve speed performance.
