I'd easily recommend ownCloud to small businesses or teams within organizations. I've not used ownCloud in large deployments, so I'd hesitate before suggesting it in a situation where more than 10 users need support. That said, ownCloud is easy to set up and multiple instances could be used to service a large user base.
I think this service works very well for me, but I have been a Verizon customer for almost 15 years. If you are someone who hops carriers it may not be the best fit. I also like that you can easily use it with all of your employees regardless if they prefer Android or Apple phones. (Whereas using Apple's or Google's services may not work seamlessly for all phones.) I think it still has room for improvement, and sometimes I worry about the longevity of utilization due to the nature of cell phone carriers constantly changing prices, plans, and every option under the sun to make a buck that we could be very screwed in the future if Verizon does something stupid (because historically, they all have)
Attention and dedication to making the product a world class product with continual product updates.
Ease of use from an administration standpoint, and a very Clear UI.
The price -- you can't beat free!
Mobile applications are great.
Integration with public S3 cloud providers like AWS S3 and Wasabi S3.
2FA authentication is supported and works great!
Marketplace Add-Ons: I love this! For example, I can install an add-on that natively opens raw images. I am a photographer as well, and being able to quickly view the CR2 Raw Files direct from the camera is fantastic! This was made possible by a marketplace add-in.
Embedded Media Players: Photos, Music, and Video files can be viewed and played right in the browser window.
Sync application to keep local files on a computer updated with the files on the server.
Access control and permissions -- shareable links!
Inability to easily collaboratively edit the same document by several people. Some advances have been made with Collabora (Libreoffice online) but it is still very sub-par compared to Office365 and desktop/online Office editing Sharepoint or OneDrive documents.
Apps for Calendar and Contacts are not part of the basic core, and although now quite supported they cannot still be easily deployed in common email clients such as Outlook or Thunderbird, separate CalDAV and CardDAV plugins need to be installed. Embedding an email solution and plugins for major email clients so they can work just by entering username and password would be good.
Risk of moving important folders/files to another location just by random drag-and-drop on Windows. Sometimes this breaks public links that cannot be restored anymore. Reverting such mistake by any of the users is impossible automatically.
When some user deletes some data in a shared folder it is put into recycle bin of the owner of the folder. The user who deleted cannot himself/herself revert such action as he/she does not see the recycle bin (trash) of the owner. Also, there is no log in the recycle bin who deleted that file or folder.
The home screen shows a little bit of everything, but being a control freak, I would like to be able to customize it. (Granted, it would most likely have most of the same elements, but, for example, I don't need photos scrolling across the top. I'd rather have buttons like quick links to jump directly to what I want or to see a further bird's eye view of the content.
I like receiving notifications that a back-up is complete, but I would like to be able to set what other notifications are and aren't allowed to push to my phone.
I have set Verizon Cloud to back up on wifi OR using the data network. But if you are using wifi while doing a content restore and you lose that connection, either by leaving the building or the local wifi dropping out momentarily, the entire content restore will stop and need to be restarted. This can be very frustrating.
OwnCloud is easy for me to use, and I believe it would be for others too. The barrier for most people will be the set up. For a technology professional like myself, ownCloud's setup is pretty straightforward, but it's not the sort of thing most casual users will be able to handle. Also, it's on the user to maintain the service. These can be taken care of by paying someone to do it for you.
Compared with other cloud services, ownCloud has been the most efficient. It doesn't create a noticeable drain on resources and very quickly syncs across all my devices. I'm usually able to save a file on my laptop and by the time I walk over and sit down at my desktop machine, it's already there. I don't need to wait as often as I have with services like OneDrive.
Regarding the community edition, there is a reasonably good support on the IRC, forums and in the issue section on Github. Perhaps a much more individual approach would be available if the premium support was chosen and the instance of the server was provided by the Owncloud company that also offers some premium extensions, not available generally. However, we did not need this level of support yet.
The paid cloud services are expensive if you need a lot of data. You're giving your personal and business information to a data-hungry organization. Local NAS solutions are too slow. We run ownCloud on an older business PC and the performance is outstanding, even for remote access, due to local syncing.
All of the others provide more free storage. Verizon should out best or at least equal the best when you are already a Verizon data subscriber. It seems that by not doing this that they want to "nickle-and-dime" their already loyal customer base
Thus far is has been a positive experience, and has saved a lot of man hours of both employees who replaced their phones to the IT department trying to help them put everything back no longer needs to go through a lengthy process.
The cost of this option is a bit higher than I'd like. I think Verizon is a little too proud of a product that every company is now starting to offer.
There is a free version with limited space, so at least trying it out to see how it will fit with your needs isn't much of a risk.
