Cloud storage software is a platform that lets us store all our files, documents, photos, and more on the cloud. In short, we move our data off our physical hard drives and store it on a much bigger hard drive that we don’t own. We use any internet enabled device to upload or download, access and organize it all.
In this guide, we’ll unpack the best cloud storage platforms available today based on their price, free storage space offered and security features offered by the platforms.

What is Cloud Storage Software?
Cloud storage software frees you from the limited confines of your device’s storage. It provides access to seemingly endless off-site servers where all your important documents, photos, and media can find a new digital home. Instead of cramming everything onto your laptop or phone, you can now upload your stuff into remote spaces known as “the cloud”.
These cloud servers are really just lots of computers clustered together by companies like Google and Dropbox, that let you rent some of the space on them. Then, once your data is stored in the cloud, you can retrieve it using any internet-connected device. This is done through your browser or a dedicated app.
You also don’t ever have to worry that someone else’s data will get mixed up with yours, because built-in tools help organize everything into neat folders so nothing gets lost in the digital shuffle. Some cloud services even “sync” by automatically mirroring file changes across devices. So whenever you update a document from work, the same changes will be on your tablet almost immediately.
Security also remains a top priority in the cloud. Encryption locks down your info, while redundancies (you can think of these as backup plans) spread copies of your data over multiple servers. So your important files don’t get lost in the event of hardware glitches and so on. In short, cloud storage software expands your digital space without limits.
What is the purpose of Cloud Storage Software?
Cloud storage exists to free you from the fuss of needing physical storage hardware. Instead of purchasing expensive servers to hold expanding digital archives, its prime purpose lets you store stuff on a remote server that you access via the internet. So no matter your gadget or location, as long as you’ve got internet access your files follow you anywhere through cloud software.
Organization and sharing also become simpler with tools that keep your information found, synced and available to teammates. Best of all, scaling needs up or down won’t demand investing in new machines — the clouds adapt effortlessly on demand.
Is Cloud Storage the Same as Cloud Object Storage?
No. Cloud storage works like your computer’s filing system, with folders holding files. It’s ideal for everyday tasks and team projects due to familiar navigation and sharing features. Each folder is a box that anyone with permission can access, with all the files in it. One file can be copied into multiple boxes, but changes to one won’t be synced to any of the copies.
Cloud object storage takes a different path, treating data as standalone “objects” instead of files sorted into one or multiple folders. Every object is in a data lake — or one giant folder, and each one gets unique tags that make specific data easy to locate. Perfect for huge unstructured datasets. The tags are for keeping everything sorted into different folders, or categories.
The difference is that one file can be in multiple categories, without you needing to make multiple copies of it. So while both solutions safely store your information on remote servers accessed over the internet, cloud storage focuses more on access flexibility while object storage dedicates its energy to monumental scalability.
How Does Cloud Storage Work?
At its core, cloud storage is all about saving your important files onto the internet. Your browser or application does the heavy lifting behind the scenes to shuttle everything from gadget to remote server. Here’s the basic rundown of what really happens.
- Software on your phone/computer starts by splitting data into small, unrecognizable pieces. This is called chunking.
- If your cloud storage solution uses encryption during transit, these pieces get scrambled into gibberish using special algorithms.
- The encrypted chunks upload over the internet to server farms belonging to your cloud provider. These servers are basically individual computers with massive hard drives, or storage space.
- These servers stash different pieces across multiple machines, so if one of them glitches, it doesn’t destroy all your data. Most cloud storage providers have redundancies in place — which means each piece will also be copied to a whole other server, usually in an entirely different location.
- When retrieving data, your cloud storage software uses your unique secret keys to reverse-engineer encrypted pieces back into usable files. This decryption usually happens on your device, so if your data gets intercepted in transit — it’s still a jumbled mess.
There are also firewalls and access controls that help keep your data safe when it’s at rest or stored safely on the server, as well as syncing and offline access options. But these all work with slight variations of the same basic steps we’ve just outlined here.
What to Put in Cloud Storage Software?
When it comes to cloud storage, the sky’s the limit on what you can upload. Photos, videos, music, documents—if it’s digital, it probably finds a happy home in the clouds. Developers like cloud storage as a remote workshop for coding projects. Businesses use it to simplify teamwork by sharing files together.
Even backups can be stored in cloud storage, since clouds safeguard your crucial data from device failures. Pretty much anything goes as long as it fits within storage limits. Just watch out for copyrighted media or sensitive info that needs extra encryption beyond the basic security that cloud storage providers offer.
What Are the Factors to Consider When Choosing Cloud Storage?
When shopping for cloud storage, it’s best to do your homework on key concerns listed in the below sections. This way, you won’t find yourself having to figure out how to move all your data from one cloud storage provider to another at some point in the future.
Storage capacity: Think about how much data you have currently and how that might change over time. Free tiers only offer so much space before you’ll need to upgrade, and each provider’s paid tiers are structured differently. Compare basic specs like included storage, upgrade options, and pricing structures so you’re not caught off guard when you hit those caps.
Cost methodology: Some providers bill a consistent monthly rate. Others charge on a pay-as-you-use model. Then there are those who charge annual fees, or offer lifetime plans. Understand how you’ll be paying so you can make sure the costs align with your budget, and you’re not stuck with an unexpected bill you can’t afford.
Security measures: Your data deserves the highest levels of protection, whether it’s sensitive personal information or a shopping list. Check that your files stay encrypted both on servers and during transfers. Look for secure login protocols like two-factor authentication (and turn them on!). Also consider where servers are based if data sovereignty is important to you.
Accessibility across devices: With cloud storage, access anywhere is the promise if you have an internet connection. But this doesn’t necessarily mean that access is hassle-free and intuitive. Make sure the software you’re considering is easy to use at all times, no matter your device or operating system.
Collaboration features: Do you want to be able to share your files and folders with other people? If so, then features that make that as easy and secure as possible are essential. Things like customizable access controls, file versioning, real-time updates and more all play a role. When it comes to file sharing — what is most important to you?
Once you’ve narrowed down your choices using these factors, the last thing to consider is budget. Which option gives you all the things that are essential to you and most of the things you’d like, and also fits into your price range?
What Cloud Storage Has the Largest Storage Capacity?
Mega shines with its very generous 20 GB free tier as well as paid plans reaching 16 TB. For the all-out largest amounts, iDrive goes up to 100 TB in their premium subscriptions and Sync has a new unlimited Teams plan.
Others like Backblaze are more limited with a pay-as-you-go style $6 per 6 TB per month, with ‘unlimited’ capacity for backups only. And while Amazon Photos is great for unlimited photo storage with a Prime membership, its video cap is low.
There is one major exception worth flagging. Amazon’s S3 storage caters towards large infrastructure needs thanks to its virtually unlimited design. So while not tailored for individuals, it could suit extreme long-term or high-volume storage demands better than consumer options.
Is Cloud Storage Secure?
Yes. Reputable cloud storage providers have you covered with various layers of protection.
Encrypted data meets encrypted transfers, so whatever you upload is scrambled into an unreadable format during transport and while at rest on servers. This alone makes your files extremely difficult for wrongdoers to access. Providers also spread data across multiple remote locations. So even if one server runs into problems, others can seamlessly pick up the slack without risk to your documents.
And tight access settings let you manage exactly who can see, change or distribute each file or folder. Plus, major cloud outfits invest heavily in security systems designed to catch intrusions and attacks early. Firewalls, intrusion detection and prevention systems, work tirelessly behind the scenes to keep bad actors locked out of their systems.
What Are the Best Free Cloud Storage Solutions?
Here are a few top cloud storage solutions with the best free plans.
Mega: If maximizing available storage without spending a cent matters most, it’s tough to top Mega’s very generous free tier of 20 GB. That’s more than enough space for years of documents, photos, and other files for many casual users. Plus, they’re well known for the strength of their privacy and encryption protocols.
Google Drive: Drive strikes an ideal balance with 15 GB in its free plan while blending seamless integration with powerful Google Workspace apps. Files stay easily accessible across Gmail, Docs, Sheets and more within their user-friendly ecosystem. Add in easy to use access controls and the benefit of Google’s cybersecurity teams, and Drive is difficult to beat.
Proton Drive: When privacy and security are the top concerns, Proton Drive takes data protection very seriously with zero-knowledge encryption and protection policies. Its free 5 GB tier is small but allows robust file storage and sharing without compromise. And you don’t get much more transparent than a completely open-source solution.
Overall these free services respectively lead in either offering maximum space, well-rounded functionality or industry-leading privacy at no cost. For most needs, one will likely suitably cover light personal or work files without busting your budget. Evaluate features to identify the best overall fit.
Is Google Drive Better Than Microsoft OneDrive?
Both Google Drive and OneDrive cover basic cloud storage needs well with free tiers and paid options adding more space over time. Each also lets you easily access files across devices and platforms with Desktop and mobile apps for a seamless experience anywhere.
Where they differ most is integration flavors and available storage. Google Drive pairs tighter with Workspace apps like Docs, freely enabling real-time collaboration. This makes Google Drive a better fit if your workflows rely heavily on those productivity tools.
OneDrive plays nicer with Microsoft Office files, on the other hand. Storing and editing documents in OneDrive keeps them in perfect sync with the corresponding Word, Excel or PowerPoint software. This tighter bond gives OneDrive an edge for related workflows.
Storage-wise, Google Drive starts users off with a more generous 15 GB free offering versus OneDrive’s 5 GB. Though OneDrive counters with a competitive $2/mo paid tier unlocking 100 GB of room. Both uphold security and accessibility well, too. Yet, Google Drive’s file search functionality could give it an advantage when digging into stored content is imperative.
Overall either service handles basic cloud storage competently. Look closest at ecosystem partnerships, free storage amounts and specific collaboration needs to determine which white-labels itself as a stronger player for your unique situations. Both deserve consideration.
What Other Enterprise Software are There?
Besides cloud storage options, another software area to consider includes enterprise resource planning (ERP) systems and CRM software.
ERP software aim to pull together different functions under one digital roof. Usually focused around finance, inventory and human resources initially, many now integrate storage and file sharing too. This seamlessly connects usually siloed operations for streamlined data access across departments.
CRM plug-ins concentrate on customer interactions from leads to service. Smart CRM tools automate repetitive marketing tasks to boost productivity. Combined with cloud storage, sales teams gain 360-degree profiles with clients’ full interaction history at their fingertips.
Together, these enterprise software form broader digital ecosystems. Connecting storage utilities and collaborative workspaces to core ERP and CRM packages strengthens whole-business visibility. Those seeking applications beyond basic file hosting would do well exploring opportunities for deeper workflows and operational insights through these related expansion areas.
