Re: saavy in the ways of SATA and SATA2
by David Roth Weiss on Jul 2, 2008 at 10:45:22 pm

[Bob Flood] "1. CAn someone direct me to a reliable and informative site about SATA, SATA 2 and eSATA?"

Just let go of that part Bob, as it's really transparent to the user. Okay? The original Serial ATA specification was 1.5Gbps, SATA 2 Serial ATA specification is 3.0Gbps. Now you know, but it's not really important.

[Bob Flood] "it seems that with a SATA 2 drive and connection, your limiting factor in throughput becomes the drive, rather than the inter connect, such that you get all the performance of a 7500 rpm video drive that the manufacturer intended, so a single drive would have higher throughput via SATA then via FW800. is this correct?"

I think you meant 7200RPM. Right?

The bandwidth of Firewire 800 is 800Mbit/sec, while SATA is 1.5 or 3.0Gbps, which is two to four times faster. The same drives can be used by each technology, but they have very different controllers, with SATA providing a much larger data pipe.

What is your objective?
