I have been using an Icy box 'Sata II Mobile rack' caddy system for several years - and mine is key lockable.
I am not being sarcastic when I ask what is cool and new...it seems it's only new from 'Antec'. I don't know what the 'e' in eSATA means, it mentions easy, but mine is also hot swappable, though I tend to power down as for the few occasions I swap it's not worth the risk.

Can I tag on a tangental but practical question?
On occasion I have wish to connect the caddy to my laptop.
The caddy consists of an outer shell and the sliding inner caddy.
I have spare outer shells, so is there a practical way to connect this to the laptop?
The box says it has both 15 pin SATA and 4 pin power connector.

This one looks solid

I've been using an Icy SATA caddy for some time too. However I had to modify the caddy for use in an Antec case because the Antec case design I have only firmly fixes 5.25" drives on one side :eek: - the other side is supported on a sprung guide. The caddy would flex when inserting the drive, preventing it from working properly.

It looks as though Antec have come up with their own solution, by making the caddy a more rigid construction.

BTW I think the 'e' in eSATA stands for 'external'.

These things are cheap and work well and the SATA drive just slots straight in.
Works with eSATA on my MBP and via USB on my windows workstations.

Mark: have you ever measured the drive R/W speeds you get via the USB/SATA bridge in that NewLink HD-HDOCK04?

(Presumably, the eSATA-to-SATA connection internally is passive, and hence does not affect the speed, unlike the USB/SATA bridge.)

As stated above it means External.

Now with a PC Specialist Quad Core i7-3770, 16GB RAM, 180GB SSD, GeForce GTX560 Ti Graphics Card, Blu-Ray & DVD R/W Burners and can't wait to set it up. Now up and running.  What a difference in Blu-Ray footage.

No, I haven't! But I can give it a go. Do you happen to know how one measures such a thing with a Mac?

Thank-you Nigel and Harry.
Re-reading the link with this in mind I'm still not clear what's what.
I assume the internal cable is an extra item to any other caddy (non'e') and that the tall thin oblong hole in the facia is a connection for daisy chaining the cases.
Because of this wiring arrangement, it seems this 'E'xternal HD can't be connected to, say, a laptop?

On Marks external link, I assume that external HD's have slower I/O etc, so are less suitable for video editing, but OK for archive/storage?

None of those assumptions apply:
Neither USB nor eSATA can be daisychained, internally or externally - only FW or SCSI works like that.
(SATA/eSATA can be Port-Multiplied, but thats a different technology requiring specific chipsets).
The Antec caddy appears to have an additional second SATA-channel connector on the front bezel, to attach to via its cable to a second SATA channel on the HBA.

Either USB or eSATA connect to any laptop with a cardbus or PC Express card slot, with the appropriate plug-in card - which can be 2 channel eSATA.
Mounted internally or externally a SATA/eSATA (or USB) drive will have exactly the same data transfer speed.
(eSATAS/SATA about 4 times faster than USB 2).

Thank-you Paul.
Using multiple icy boxes I use one inner caddy for each HD but only one of the outer cases for the 5.25 inch bay.

If I understand correct, I could buy 2 of the linked eSATA caddy and use:
1)One to replace the Icy Box internal with the same (non-SATA) connection.
2)One to connect to my laptop (eSATA), upon buying PC Express card.
I can then hot swap drives between laptop and main pc?

This would be a bonus over my current set-up as 2 caddy would fulfill future needs as the HD's slot straight in, unlike Icy box, where I tend to have an additional case for each additional HD.

Hi
Yes to that more or less.
But the unit Mark M linked to would be better to attach to a laptop.
The Antec caddy is designed to fit into a computer 5.25" bay. You would need to mount it into an external DVD-type case to supply power and connect it to a laptop reliably.

eSATA has several advantages over SATA for external use. SATA connections are not robust enough for external use - 50 plug-in operations as against 10,000+ for eSATA (and the eSATA spec has slightly better defined voltage pulse transients to allow longer cable runs over 1m).
