Like those other services, Box has a desktop application which lets you set up a folder on your hard drive to sync automatically with the internet. However, despite the fact that it consumes an unreasonably large amount of system resources, it works incredibly slowly– something customers have been complaining about for several months.
Here’s my speedtest.net results:
Not too shabby, right?
Well, I’m currently downloading files through Box Sync at about 5 kBps, or about 0.08% the speed the connection is capable of. Meanwhile, the program is eating about half my processor power (though it jumps up and down) and 300 MB of RAM.
Dropbox seems to be the king here, though Google Drive isn’t too bad. Spideroak’s always been slow thanks to its client-size encryption (they’re a zero knowledge host), but even Spideroak seems spry compared to Box Sync.
So: Caveat Syncor.
