eSATA (external SATA)

There seems to be some confusion in the NGs about eSATA.

The most prominant features of eSATA are the longer cable
length (up to 2 meters), the cable's shielding, and the plug to
accomodate the shielding. eSATA can be used with external
adapters for both desktop PCs and laptops, and external
enclosures are available that have their own power modules
and cooling fans.

Here are some links to representative info:

Not in this group, unless you want to start it with this.
So why only posted to this group?

Well, those are obviously not eSATA.

Of which only the last one is eSATA.

Unfortunately it doesn't say whether it has an eSATA to SATA bridge or not.
"Interface: E-SATA Only" suggests that there is only an eSATA connector.
Want to point us out to eSATA diskdrives?

Q.E.D. on your confusion.

Because you're here, Rod.

Very funny. Not so clever, though, Rod.

You have to extract your head and read the page, Rod.

Two of the three cable types involve eSATA, Rod.

You are really dumb, Rod.

OK, I'd like to know more about eSATA so here are a few questions.

Regular USB/Firewire enclosures require a bridge chip to translate
between the interfaces. Since eSATA is native, I assume such a bridge
chip would be needed? Is the only difference the connector? In which
case the enclosure would just need a simple connection between the
eSATA and SATA connector on the host/device side. Or, are there some
other difference such as signalling level that need an IC to take care
of?

How is power usually supplied for 2.5" eSATA enclosures? I've seen
some use USB power(probably a Y cable for more current) but since an
unconfigured USB device can only draw 100mA, doesn't the enclosure
have to enumerate before it gets the full 500mA? If so wouldn't
another USB chip be needed?

between the interfaces. Since eSATA is native, I assume such a

According to the Silicon Image white paper on eSATA,
the differences between SATA and eSATA a

1) the cable and its connectors,
2) the higher signal levels needed to accomodate
the longer cable, and
3) the shielding and grounding requirements for the
external enclosure and the hard disk drive.

In which case the enclosure would just need a simple
connection between the eSATA and SATA connector
on the host/device side. Or, are there some other difference
such as signalling level that need an IC to take care of?

The white paper implies that with an eSATA cable of
1 meter or less, the SATA control chips should work.
The brackets listed as "SATA Internal-to-External Bracket"
should do the job in such a case:
http://www.firewire-1394.com/externa...-solutions.htm

The white paper also mentions SATA/eSATA signal level
adapters on PCI cards for cable lengths up to 2 meters.
These currently are made by SIIG and probably others.

How is power usually supplied for 2.5" eSATA enclosures?

As far as I can see, Kingwin doesn't make eSATA enclosures
for 2.5" SATA hard drives. For 3.5" SATA hard drives,
the Kingwin website lists a plug-in power "adapter", i.e.
power supply module, for its eSATA enclosures. The
eSATA enclosures for 3.5" hard drives are models:
JT-35E-BK, JT-35EU-BK, KH-350SE-BK, and the
KH-350SEU-BK.

I've seen some use USB power(probably a Y cable for more
current) but since an unconfigured USB device can only draw
100mA, doesn't the enclosure have to enumerate before it gets
the full 500mA? If so wouldn't another USB chip be needed?

I'd not use USB power for a 3.5" hard drive. I don't know
about 2.5" hard drives powered by USB. For reliability of
any external hard drive, I'd want a cooling fan and a dedicated
power supply.

The white paper no good to you, huh.

According to the Silicon Image white paper on eSATA,

2) the higher signal levels needed to accomodate the longer cable, and

Right Timmy, so where are the drives with eSata signal drivers?

3) the shielding and grounding requirements for the
external enclosure and the hard disk drive.

In which case the enclosure would just need a simple
connection between the eSATA and SATA connector
on the host/device side. Or, are there some other difference
such as signalling level that need an IC to take care of?

The white paper implies that with an eSATA cable of
1 meter or less, the SATA control chips should work.
The brackets listed as "SATA Internal-to-External Bracket"
should do the job in such a case:
http://www.firewire-1394.com/externa...-solutions.htm

The white paper also mentions SATA/eSATA signal level adapters

on PCI cards

So Timmy, where are the drives with eSata signal drivers?

for cable lengths up to 2 meters.
These currently are made by SIIG and probably others.

The eSATA enclosures for 3.5" hard drives are models:

JT-35E-BK, JT-35EU-BK, KH-350SE-BK, and the
KH-350SEU-BK.

So Timmy, does it pay well to be a Kingwin shill?


I've seen some use USB power(probably a Y cable for more
current) but since an unconfigured USB device can only draw
100mA, doesn't the enclosure have to enumerate before it gets
the full 500mA? If so wouldn't another USB chip be needed?

I'd not use USB power for a 3.5" hard drive.

No kidding: Like you could.

I don't know about 2.5" hard drives powered by USB.

There isn't much that you really know, is there, Timmy.
Just some pretend loudmouth showoff kiddy.

For reliability of any external hard drive, I'd want a cooling
fan and a dedicated power supply.

So who needs 'em? You're too hung up on specs and
published standards to move your bowels without a manual,
