So I just bought a U3 smart pen drive (see http://en.wikipedia.org/wiki/U3
) thinking that I need a bit of a portable "office" for university and maybe using others' computers. Before buying it I only scratched the surface of that U3 stuff, and thought it sounded excellent. Now I'm not so sure... Not that it's bad or anything, but I'm not sure whether there's any real benefit to running my portable software U3 style or just "regular portable" (like http://portableapps.com/
).some Pros:Autorun when inserted.
Since U3 involves mounting two partitions, one of them is a virtual CD-rom drive with CD autoplay features, that'll start the U3 launcher on the other regular flash partition. (read above links for better explanation)Compressed format.
Not that important, but space on the flash drive is saved for other things. With 4 gigs of space, I don't know if a couple hundred kb's matter With an AHK script, most apps can be "U3ized"
Take a look at U3Helper
!some Cons:Needs two drive letters.
While this is no problem on my home system, it can be a problem on a university or other "networked" areas, where the system might not allow more than one drive letter for inserted flash drives. I know the place I study gives me problems with this, thus making the drive pretty much unusable Needs to uncompress to run.
While compression may save space on the drive, I think it makes all apps a wee bit slower since it needs to decompress them to fixed drive to run.
Since I've only recently started using this stuff, these lists are small, but I'd like other's input as well. Both pros and cons with the U3 system and/or the "regular" portable solution are very welcome!
