SATA3 is 6Gbps at 8/10b encoding: or 600MBps.

SAS is 12Gbps or 1200MBps (I don't know if it uses 8/10b encoding, but I'll assume that for simplicity)

------------

Hard Drives are no where close to breaking the SATA3 barrier, let alone the enterprise SAS 12Gbit barrier.

You're probably still correct, but what I saw from the immediate next generation was something like 9 platters and two or more independent read/write heads.

So we might be headed for what used to be a single write head (and its single throughput stream) to double, triple, or more.

Especially since the additional read heads enable the datacenters to scale shared object storage more effectively with more dense drives, which seems to be the main customer/application for HDDs at this point.

I remember a long time ago when I upgraded my motherboard and was pleasantly surprised that my SSD suddenly became twice as fast. Didn't even consider that I was switching from SATA2 to SATA3, was more interested in my CPU upgrade.

On an unrelated note, are you the same Dragontamer that I've met and played with at PDXLAN? Or do you just happen to use the same alias?

Unlikely me. We must have the same online alias (it is a very common alias in my experience...)
