What is the sync process for Dropbox and Evernote?

Ok, thanks much Scott.
Obviously the group has limited experience with large projects that could benefit from a continuous safe on line storage system.  Taking notes and whatever is not what I need to do.   I am a photographer running Lightroom and Photoshop.  I have a library of about 1000 photos.   I have been warned by Adobe's user groups not to trust Evernote for a continuous backup of the library.  Primarily because in the sync process, while editing in Lightroom, the storage can get corrupted if we are not very careful to complete the sync before closing the Adobe apps.   Evernote warns us by spinning a wheel.  Dropbox doesn't "seem" to have this problem.  Or does,  and  do not supply a feedback during the sync process.
I have Comcast Internet.  There upload speed in Philly, near there headquarters, is limited to 10 Mgbts per second.  Elsewhere in our country a customer is lucky if they get 1Mgbs.   The reason for this as stated by Comcast is it impairs  hacking and stealing etc etc.  Verizon advertises  much higher upload speeds but has limited nationwide coverage with their fiber optic system.  And they recently dropped email.  So I guess we can forget about online storage unless it is done in bits an pieces which is what Evernote and Dropbox would do if they could handle this kind of continuous traffic.  I can't afford a T1 long line which is what business uses to reach offline storage.  Obviously not everyone is equal.  Hover, in Canada, seems to have amazing throughput to Philly.
The only other option seems to be to buy commercial quality SSD's.

I do appreciate you taking the time to respond.
Thanks again,
Howie
