Hardware, Embedded Systems "The Serial ATA International Organization today, made the third-generation SATA interface official. The new interface provides a 6 Gbps high-speed serial data connection between the system and most of today's data storage devices such as hard drives, solid-state drives, optical drives, and enterprise tape drives. The interface also provides connectivity to external storage devices in its eSATA port variant. It is 100% backwards compatible with devices that support the SATA 150 MB/s and SATA II 300 MB/s standards."

You can easily saturate SATA-II port using multiplexer and 4 disks. All neatly connected to single eSATA port in motherboard. Increased bandwidth is nice.

BTW, SATA as CPU interconnect? What a mad idea is that, could you provide link?

The only exciting use I have seen of SATA has been as an interconect for multiple CPUs.


come on, hypertransport 3.1 is the way to go for disks ;)

Why on earth would you multiplex multiple disks on a single SATA port?

In any case, I saw the SATA interconnect used by some SUN guys to piece together a mulitprocessor system made of multiple FPGA boards, each running a OpenSPARC instance in their respective FPGA.

Here is the link for the presentation SUN gave us at the RAMP retreat:

(see slide 17)
