Are eSATA2 and eSATA3 cables/ports physically the same?

Hello,

We have to design a prototype home server for school. The idea is to get the most of the ideal buyer's dollar and with features that will sell it well.

I have chosen this motherboard :ASRock A330ION. It is a great feature rich motherboard with lots of possibility. I would like to install an ASUS U3S6 USB 3.0/SATAIII Card. This would enable USB 3.0. Since I have no need for the SATAIII on the card, (will be using standard SATII on motherboard), I was curious to see wheter I could turn these 2 SATAIII ports into 2 eSATAIII ports.

I want to use something like this to get some more I/O out of the machine. It turns 2 standard SATA ports into 2 eSATA ports that can be installed in an expansion slot. This is exactly what I am looking for.

However, I would like to know if there is physically anything different between SATAII cables and SATAIII cables. I was under the impression that the only thing SATAIII about SATAIII was the chipset controlling the drives. Am I wrong? If so, does anybody know an SATAIII to eSATAIII bracket adapter thing?

Thanks for your time.

Check this out and see if it will fill your needs. It supports 6Gb/s and is backward compatible with 3Gb/s SATA.

Oh my. Thanks alot! It got one nasty review but that was just someone complaining about their $5 purchase. That should do it! If they come out easily, I'll find a way to keep them in. (Adhesive tape or something).

Thanks.

Last time I looked, several years ago, the eSATA standard calls for
a slightly higher transmission voltage -- in order to support
longer external cables. So, when it doubt, it's best to purchase
cables that are rated for 6G and have eSATA connectors, both.

Although, in a pinch, cables with eSATA connectors should already have
electrical compatibility with the slightly higher transmission voltage.


The item linked above seems to fit the bill:

Another detail to consider is the support, or lack of support,
for "hot swap" at the ports to which those cables are connected:

typically, "IDE" mode in the BIOS does not support hot swapping,
whereas "AHCI" and "RAID" should support hot swapping
(Intel "Fan Boy" speaking here).


RTFM (Read The Fine Manual -- not always "F"ine, however :) 


WORST CASE is that you will need to connect -and- power up
your eSATA HDDs and enclosure(s) BEFORE booting your machine.
