Microsoft OneDrive

In terms of cost and usability, I think OneDrive is the best product out there. I've tried so many cloud providers like Amazon, Google, Dropbox, Box etc etc and I think that OneDrive is the most trustworthy platform and great if you're concerned of your data suddenly being deleted because some automated scan suspects something "illegal" on your account (for example, Google has a habit of suspecting pirated content exists and disabling your entire account over it)

With all that said, it's not perfect. The Android app tends to ignore your requests to ONLY upload photos (it uploads screenshots and various other junk you don't want in your Camera Roll) and the UserVoice feature suggestions are basically ignored.
There's no file tree directory view and you can't unzip within the browser. These aren't features that absolutely destroy your use of the service - but they are basic essentials!

OneDrive makes sharing files between computers and phones really easy.

When compared to alternatives such as Google Drive and Dropbox, OneDrive is terrible. Issues I have include files not syncing, opening files as read-only after clicking to open an editable copy, and finding newer versions of a synced file on the server.

The best thing about OneDrive other than lots of people using it already is that it can sync SharePoint sites, making it good for businesses in this one regard.

There are multiple versions of OneDrive depending on where you download them from. The Apple AppStore version, for example, periodically corrupts the account and forces you to delete everything and re-find every folder you want to sync. Individually. This occurs about every 2-4 weeks.

All of the versions, however, offer zero control over how and where files are stored, burying things in nested folders, or in insanely long file names. On Windows it doesn't even allow you to store files on an internal hard drive it decides is unsuitable.

OneDrive is absolutely awful.

Probably the worst cloud service you can get.
I tried to use it for university, and it gave me lots of problems so I finally had to change to Google Drive (DropBox is good too):

[ANDROID APP] (I haven't tried the iOS one, but probably the same)

• Lacks lots of features, they put one feature and then change it again at worst. They don't listen to users at all, you ca see the OneDrive's UserVoice is full of requests that doesn't even get accepted.
• There was a "feature" that automatically made albums out of your personal photos, which couldn't be disabled and didn't even work properly. Sometimes I got over 8 notifications a day about new auto-albums being created. It took about 7 months to them (even with lots of requests on their Onedrive UserVoice) and then it finally could get a disable option.
• The built-in PDF reader was horrible, sometime didn't even open and lacked essential features (like upload to OneDrive, the Find function didn't work properly, you couldn't even open the PDF with another app).
• There was a reward in which you could get 100 GB extra on OneDrive if you installed their Office apps…Yep I tried like 4 times but didn't even work.
• As they followed their horrible "Modern" UI approach, every section where you see your files (Icon, Name, Size…) occupied way too much, so there was very little space for every thing. Did a request on OneDrive UserVoice, got lots of votes, but a waste of time.
• The app ocuppied too much space in the phone (even Google Drive was way lighter, which has more features), so another reason to uninstall it.

[DESKTOP APPs]

• As people already know, it already comes in Windows, and does things you didn't even ask for as their strategy to try to get customers. At the time I was using it, It didn't even have an interface (now it does, but is horrible), so you couldn't know what the hell was OneDrive doing (no info at all, won't even tell at what speed it was downloading/uploading), a just too basic function in my opinion.
• Their macOS app is unusable, with serious problems in performance and sometimes not working.
• Their Linux app is another pain, just switching to MEGAsync is far better.
  (seems like things outside Windows isn't very important to them…)
• All those problems have already been reported to them (via OneDrive UserVoice), but have taken almost no action to it.

[WEBSITE]

• Another mess, and a pain to use. I had to edit some Plain Text files (with less than 100 lines) and sometimes it would lag or freeze and had to close the browser and open again.
• Their Office Online apps are slow and buggy for apparently no reason. I used Word and PowerPoint Online and it had almost no functions when their competition (for exemple Google Drive) had more than capable apps. Even their notes app, OneNote, would stop loading and took too much time to show my notes (I mean, they're all Plain Text, and about 15 sections…).
• Even today their OneDrive website's UI is not fully changed to their new messy approach, when they have been like 3 years with it.
• And finally let's not forget the shameful downgrade and scam they did to their users. Before you'll get this cloud space: 15 GB for creating and account + 15 GB for installing their app and enabling their Pictures Backup function + 5 GB for every friend recommendation (with a limit, of course),
  . So totally over 30 GB free. How all this ended?
• Well, from overnight they realized they couldn't afford all those GB they were giving to the accounts, so they cut it down to just 5 GB, rise the prices, and disable all bonuses (although you can still get the 5 GB friend recommendation bonus). And all that because a business with the size of Microsoft couldn't anticipate to what was too obvious (there's plenty little business out there wich offer unlimited GB without lying to their users).
• What's worst about all that? You could save your space GBs if you asked them for it, but…They didn't warn/notify to ANY OF THEIR USERS. I found out about it while reading online news (it was a small blog post, so Microsoft made sure that very few people would know about how to keep their space GBs). WHAT A SHAME.

[Conclusion]
Just use Dropbox (2 GB free), Google Drive (15 GB free), or even Box or MEGA (35 GB free, with temporal GB bonus). OneDrive just isn't worth it, as a student, too much problems to deal with (I admit I did expected it, as it follows same experience as the rest of Microsoft products).
You can still use it if you just need online Backup and don't need to edit any files (although you'll only get 5 GB, so better sign up to any other cloud).
DON'T PAY FOR IT (unless you're paying for Office Online and you get it additionaly).

OneDrive and Dropbox are by far the best.

• Preinstalled on Windows 8 or later
• Currently i am using this because i have 1TB Free Storage in onedrive for business
• OneDrive Files On-Demand helps you access all your files in OneDrive without having to download all of them and use storage space on your device. (Odrive Feature like)
• Microsoft states in their?Terms of Service: “You must sign into your Outlook.com inbox and your OneDrive (separately) at least once in a one-year period, otherwise we will close your Outlook.com inbox and your OneDrive for you.”
• Dashboard are very slow and timed out when too much operation such as 200 batch delete files or move, etc
• Recycle Bin Restoration are very bad, it won't restore file with same folder name !
