The modicum of security these companies offer are better than the nonexistent security practices at the places I've worked for, lol. I trust them way more than the average user or small business.
if you are tech savvy, like to keep up to date on security and are ok with the hassle of setting up a NAS, sync stuff and know how to keep it secure, perhaps. If you had to pay me to do it for you, a few dollars service fee might be much cheaper...
