Dan Sung has written a very detailed comparison of the five main cloud storage competitors. And I agree with this fragment of Dan’s conclusions:
(…) The most powerful approach of all, though, is probably to use these things in combination. Use the free 25GB from SkyDrive for your photos, Google for your docs and mail (or perhaps more Windows Live) and Amazon for videos seeing as there’s no file size limit. Dropbox is the one to use for convenience. It’s the best syncing tool of the lot and given that storage on the service isn’t cheap, use it as just that – a tool.
Possibly the best advice of all is to use them all. Use them all up until the point where you have to pay for them. That way you’ll max out your storage and minimise your cost but perhaps use each service for just one type of media. That way you might actually be able to keep track of it all.
You need only remember one secure password – the passphrase that unlocks your password vault. This Troy Hunt essay is very worthwhile – Troy explains in detail the bad things that can and will happen to you by using the same simple passwords across all those Internet accounts.
(…) And this brings me to a neat philosophical conclusion; security is all about risk mitigation -you never actually become “secure”, you merely decrease your risk. On balance, the risk of your account details sitting out there in even a very secure website is significantly higher than having them sit there in your 1Password file.
But beyond just security, the password manager route is a very handy solution. Having all your accounts handy on all your devices and being able to simply logon with the once strong password is a very convenient route indeed.
And finally, when the time comes that you realise one of your accounts has been breached (and trust me, it will come), it’s no good thinking about password security then – it’s too late. So put aside a few hours one afternoon, spend just a few dollars and get yourself organised. Either that or start developing a taste for acai berries!
Troy recommends the same solution we prefer, 1Password on Dropbox. For that solution you need two strong passwords, one each for Dropbox and your 1Password file. Then all your very-strong-passwords are available to you on all your devices (computers, smartphones, iPads, …).
