Box

Pros

There are many things to love about Box. For one, its Business plans come with unlimited storage! We started out with Free just to try it, then moved to Starter then Business (as we needed more than 10 users on board). It's worth it esp for small to medium-sized businesses looking for a secure place for storage with tons of extra features for both admin and security.

The 5GB upload is enough for the big multimedia and other iso/archive files we have.

For our admin, the integration with our Active Directory saved us from having to require our users to create/maintain an extra account (user/password) for Box. We are also proud to announce to our team about its security features like SSL, encryption, and even two-factor authentication for the meticulous.
Although​ we haven't had the need for the DLP (Data Loss Prevention) that Box advertises, we are happy that this is part of our subscription and gives a little extra boost of confidence with our files.

The corporate logo can also be incorporated into the platform to make it personalized according to your company's branding scheme.

Box also offers a ton of possible integrations. So far what we use are integrations with Google Suite (e.g., docs), Salesforce (CRM), and MS Office 365. This makes it easy for users​ to create content is our usual platforms and then easily save and manage them in Box.

Cons

We have quite a number of staff who already use other online storage platforms (Dropbox, Google Drive). Note that Non-Box users can only access files as Read-Only... in which case our people really had to be forced to create an account for edit purposes and collaboration.

Pros

I used it and introduced it to my research group when I was in grad school few years back. We also ended up getting a larger size account to fit our needs. University purchasing handled the financial side of it, but I'd like to think our recommendations for enteprise scale buys were taken heed.
BoxSync when used in conjuction with a box account does a great job of doing automatic backups on the cloud, that also help in access from different computers/collaborators simple.
It can handle large file sizes (5 GB file upload limit) for most work, has excellent integration with word processing for online document editing. Note, I have not tried very large single file uploads yet, the largest has been a movie file of 750 MB.
Recently they added notes feature which is useful for commenting while sharing files.
Mostly it is a very stable and secure cloud backup tool, great for workflow and content management in groups.

Cons

I dont know if they ever had a referral program unlike dropbox. No other major drawbacks as a user. By default, it sends a lot of emails whenever anything is changed in the folders. turning off that feature took a while to figure out for me.

Pros

The ease of use of spinning up Box folders and collaborating among internal employees or external clients/customers. The granular permission settings within each folder allow the administrator ("owner" or "co-owner") help regulate privileges from editing, to downloading, and reading which is a great tool when looking to share with multiple parties at different levels. We stopped sending attachments via e-mail (not secure) and simply use Box now to point toward a Link where the file is located. If you don't have access to the link, you are unable to see the file. Our employees and customers love this feature and it keeps everyone involved and access privileges in check.

Cons

When using Box Drive, it can be a bit slow to sync when creating new folders, or modifying file names, directly on the desktop application (recommend using the Box web site), however, this is extremely minor. we have had many successes using Box and have not even considered exploring any other solutions for over 5 years.

Pros

They concentrated on the enterprise first, which is valid. Therefore security has always been tight, platform support is solid, and enterprise administration is very robust. Shared folders are great in a workplace and make everything very simple to get the right docs to the right people when they need them. Box is definitely an enterprise company, with the support to back up that claim.

Cons

I should start by saying I tried Box, Dropbox, and Drive head-to-head back when everyone was going to cloud-storage and my experience with Box since then has been on and off. I'm still a current user of Drive and Dropbox and I pay for both every month. Our office doesn't need the level of admin support Box provides, which is the only feature that puts it ahead of the competition.

Box was just never as feature complete as Dropbox, I don't want a separate cloud storage provider for business and for home use and Box lacked simple tools like automatic photo upload. As well, the web interface lacks and the uploads feel slower and more prone to error when compared to Dropbox. It's improved lately but it's still behind in file viewing support, etc.

Also paid users have a max file size!!! Unacceptable if you do any sort of video/graphics work.

Pros

The most beneficial thing about the Box software is that Box has enabled us with easy sharing of files and data which in return have saved us precious time for other activities and we have gained utmost benefit from it in organizing our employees and professionals content. Box has secured all of work and we can easily retrieve our files in the most efficient ways. It also includes some highly efficient tools which and we gained allow us to organize and sort the data in the most easy way.

Cons

But in accordance to our business objectives, it does not fit 100% well cause there are some requirements that has to be fulfilled via other tool to keep us working. So it also needs some improvements from its own end. It also needs to improve its way of organizing the data. We are mostly confused in retrieving the files and folders while looking for specific contents. Box has limited storage capacity for new users. And its additional storage could be bought for high prices which are reluctantly rated at very high price.
