Unclear how long this offer from Sync.com is available. The offer is for existing users, so if you're a new user you'd have to do a free sign-up first (which gets you 5GB, plus additional GB for referrals, using an app, and a few other options):
- Sign-up (you could use the OzB random referral link below to spread the love), then
- use the subscription upgrade link in this deal to get the discounted paid storage for 1 year: 200GB US$45, 2TB US$72, Unlimited US$405, all plan will renew at the regular prices.
Not bad for a fairly well-regarded cloud storage service which isn't US-based (they're based in Canada). While the various lists online that rank/score cloud storage are often unreliable, sync.com often ranks among the top five across a range of lists, particular with end-to-end encryption and zero-knowledge authentication. It's worth reading a few different reviews to understand pros and cons of any cloud storage provider.
I've used their free account for a long time, but haven't before been offered discounted paid storage. The free service has been reliable, though upload speeds are rarely great (a common problem for most cloud storage, but YMMV) and the experience from the Android app can be mixed when adding new files. Mac and Windows apps and web interface have all worked well for me. For simple uses, the free sharing of some folders and documents has proved useful within the free account.
