    First part of my two part question.

    Would you guys go for a external HD with 1 TB at 7200 rpm at 3.0 GB/S or

    640 GB at 7200 rpm at 6.0 GB/S?

    Size not that big of an issue. Does the transfer speed make a big difference?

    Secondly... I plan to also connect this to a pc with an esata port (the HD has one too). Will this give me close to internal HD speed? Sorry if this is real noobish.

    As platter based, mechanical storage devices (HDDs) don't have such high data throughput as S-ATA 6Gbit/s offers, namely 500 to 600 MB/s, there is no point in getting an HDD with such interface, as HDDs normally peak at 120MB/s (if 7,200 RPM), for which even S-ATA 1.5Gbit/s will suffice. Only if you have one of the newer SSDs, which are even faster than S-ATA 3Gbit/s (285MB/s), the S-ATA 6Gbit/s makes sense.

    Therefore it is up to you, if you want more external storage or less internal storage.

    Did you read his advice... or did you just not understand?
