Sorry John, there is no advantage to using eSATA over FW to do backups. First there is the cost of the needed adapter, and then there is the
twitchiness of the interface itself to contend with.
Then why does Apple use a SATA interface inside their
computers if it's too "twitchy"?

Because internal SATA is not the same as eSATA. The internal SATA
connector simply isn't designed for the stress/strain/repetition of an
external I/O connection ... which is precisely why the SATA standards
board rejected it for external SATA and approved the less-bad eSATA
connector. Go do your technology research, John.

You are talking about a non issue, the connector isn't the issue. It's the rate of data transfer and you know it's faster. There are adapter cables that will let you plug in a regular SATA drive to the different eSATA connector.

This is a minor issue. I remember someone having to buy a USB to Mini USB cable to make an external device compatible. It did not come with a cable and the person thought a regular USB cable was all they needed.



I mean if FW is so much better, why not use it for the internal
connector for the HD on all Macs?

Because paying more to have the superior connector for *external*
connections simply isn't value-added for quasi-permanent and stress
relieved *internal* connections.

No it would not. A FW port would be very easy to put inside. You're a damned liar and clueless. Everyone who does backups and restores as part of their JOB knows that eSATA/SATA is way faster than Firewire. Sometimes you don't even need an enclosure for the external drive. The external adapter comes with a power connector that extends a power connector from the internal power supply.

I would love to hear your answer as to why Apple is dumping FW on some of it's computers. LOL


I guess all the PC makers
in the world don't know as much as you because they think SATA
is just fine for storage, even Apple. I tell you what, why don't
you get FW and run your OS off it. Then you'll find out why the
companies use SATA.

The basic reason why many PC manufacturers offer eSATA is because it
is cheaper than Firewire,

Complete bull***! PC manufactures put FW headers on the motherboard. How easy would it be to produce a cable that would just change the FW header on the MB to a standard FW connector. You are full of bull***. The reason they use SATA is because it's faster and more efficient.


and because their profit margins are so
slim, they're trying to save a few pennies & dimes anywhere they
can. Specifically, the technical cost of an eSATA port is quite low,
because it can be added by simply externalizing a preexisting internal
SATA port...no additional controller chips required.

Already shown that this is complete bull***.


Go do your technology research, John.


Here we go again, I've shown you time and time again why FW is slower. I've also shown you that Apple is dumping FW on many of it's computers. Why haven't they dumped SATA?


eSATA is identical in performance to SATA, just so you know.

When you're only measuring simple I/O transfers, sure.


I'm glad you finally see the light. There is nothing more to be said.
