I have been using Infomaniak services for a few years now. I have my email with them, several domains and use Kdrive almost exclusively these days. Talking about Kdrive specifically, it is fast and has all the typical features you would expect from these types of services. The cloud side with the office integration is really good too.
If anything, the only negative I can find at the moment is that the app does not offer a lite mode (download as you need) feature for Linux so you have to download everything. That said, it does offer a WebDav feature which integrates well.
As for the kSuite, I would say you only need that if you are using it for business. Otherwise the solo or family package would suffice. I have kSuite too and it has some additional features but nothing you would need as an individual.
Hi, my bad on the ‘family’ reference. It is the ‘teams’ package that I use, I just use it for my family. Like I mentioned before though, it is far more cost effective than the kSuite, which is targeted at businesses.
As for the transferring for data, this is possible via a feature in kDrive. It is capable of transferring from a number of cloud storage services, including OneDrive. You can get more info on that here: https://www.infomaniak.com/en/support/faq/2406/import-external-data-to-kdrive
I still have my OneDrive at the moment but aim to close this down. I use my Synology to synchronise the data between kDrive, OneDrive and my Synology for data safety. (Yes, this is overkill) I will eventually remove OneDrive from that as I get a better home cloud setup in place.
