Would you get an esata adapter for the express card port? If so, why bother with an extra device/driver/thing to go wrong, just plug into esata.
Although if you haven't picked out a laptop yet, and can't find one you want with an esata port, then exp card is the alternative.
the case exactly. if eSATA port is built in, then the case is solved. But some laptops come only with an Express Card port instead (a Sony Vaio im looking at) and hence the query.
But the main issue - will one loose considerable performance by going with an eSATA-to-Express Card adapter? If so, then i'll ditch the idea and look for a laptop with eSATA built in directly into the laptop.
