hi there, what exacty is the point of having an external sata port on the back of a machine? the A8N32 sli delux has one. what can i do with this?

I wondered the same thing because without running power to the outside of the case it would be useless.

Also needs an eSATA cable and right now the price is silly, something like $12+ each from my product search.

what exactly is an eSATA cable? is using this external sata port just an alternative to using an external USB/firewire hardrive? if so, would an external sata drive be faster than a usb2/firewire drive?

what I understand is that they are used w/ servers and the like. With my P5N3SLI Deluxe, i was trying to plug a regular cable into it w/o looking & then felt silly.

The eSATA supports SATA2 @ 3GB (whether the MB really supports this is another mattter).

I know you can get SATA external controller cards so why the eSATA, idunnaknow. SATA is 150/300 Gb and USB2 is 400mb. Hope someone can tell me why eSATA would be better unless it is needed to support MS Vista lol!

sorry i don't feel like doing math right now :lol:  what's more, 300gigabits or 400megabytes?

Encarta saysssssssssss: Gigabyte: a unit of computer data or storage space equivalent to 1,024 megabytes

this means that Gb is much more gooder than Mb

when they say sata is 300Gb per second, isn't it 300 gigabits? i always thought GB = gigabytes and Gb = gigabits. and MB = megabytes and Mb = megabits. am i wrong?

Certainly, 400 megabits is only 50MB/s. USB 2.0 is 480 megabits, 60MB/s. SATA is 1.5 and 3.0 gigabits, roughly 150MB/s and 300MB/s (the math is wrong using 10's instead of 8's, but the SATA organization doesn't seem to mind).

Anyway, SATA is much faster than USB 2.0 from the base spec, but it gets worse: In reality, USB 2.0 can't get anywhere near its rated througput. USB 2.0 peaks out around 30MB/s in real use, and that means SATA 150 is 5x as fast, SATA 3gigabit is 10x as fast as USB 2.0.
