Sounds like a bad idea.

Keep games on your internal HD, but move all the porn to an external.

you can do it but it will dramatically increase load times. internal desktop SATA drives are realistically 4-5x faster than USB-connected drives. it's probably 2.5-4x the speed for internal laptop drives. also, external drives arent meant to read and write excessively. they're intended for archival purposes. the I/O card in externals can fry with constant use, and many of them do.

I did a little research... The hard drive in my comp is at 7200RPM

I see tons of External Hard drives that run at 7200RPM. Does it become slower because of the connection from the HD to my comp?

Also, I thought about just replacing my internal hard drive; which sounds like a pain with buying an external hard drive and buying a software to ghost all my stuff on it. Then transfer it back. (That is my guess as to what i would do). But the replacement would be 250GB and only 5400RPM.

Would the RPM decrease make that much of a difference?

I am quite ignorant on this topic, and thanks for your help.

Sweet, thanks for sharing all of your computer knowledge. If I need to get more memory soon i will probly get the HD you linked.

that drive looks good.
