simple question.

why do eSATA enclosure list a capacity limit??

doesn't the data just go direct over the cable? why should what is basicly a converter cable with an external power supply limit storage?
 
Depends on how the enclosure is designed.

Some enclosures that are eSATA only don't have any electronics in them at all ... just a cable that connects the eSATA external port to an internal SATA pigtail. These enclosures should not have any size limit.

Other enclosures that offer eSATA also have a 1394 or USB external connection, or have the ability to use an IDE/PATA drive inside rather than SATA. For these enclosures, the electronics that are doing the interface bridging can impose a size limitation.

Conceivably, some enclosures might state a size limit to ensure that you only use lower capacity drives, which run cooler, and are therefore within the enclosure's thermal limitations. I would say these enclosures would be marginal for any use in the first place.
