External RAID system for E-Sata laptop

I'm intentioned to change laptop and I'll take one with E-Sata. I want also to be able to use external RAID system, like for example two western digital velociraptor 10.000.

Anyone knows some external box that supports 2-4 HD, has internal raid card, and have a single E-Sata connection to connect it to a laptop or desktop with E-Sata?

Thanks.

eSATA is simply standard SATA with a slightly higher
transmission voltage, to support longer external cabling,
and a different connector to distinguish the two.

You'll need a controller inside your laptop that
supports "port multiplier" functionality,
or an adapter like this Express Card eSATA controller:

(found the latter at Newegg searching for "laptop port multiplier" )

Check also at Addonics: http://www.addonics.com
e.g.:

They have tons of devices that may help you.


Another one is Cool Drives: http://www.cooldrives.com

I don't think that Enhance Technology caters to laptop users,
but their products are very well engineered: http://www.enhance-tech.com/


Our recommendation: get a laptop with an Express Card interface,
and go with Addonics' Express Card eSATA controller above,
because they have already done the necessary integration
with external storage enclosures.
