If your logic is to be followed through, then every thread should deleted once the original poster's questions was answered. The forum stores all these threads so you could use the search function, and instead of having to WAIT for some good samaritan, you could find the answers right away left by those same good samaritans back in a day when the question was new.
Expecting answers to be given to you when you want them and not search for them, basically assumes that ONE person's time is more important than MANY people's time.

To top it off, some of the less carputer oriented questions can be answered through means of and basic self-education. Such as this topic.

To the original poster, if you want to start understanding as opposed to just a Yes/No answer, compare speeds of the devices you want to use AT133/USB/FLASH and whatever else. Some answers become self-evident.
