MEGA:最值得信賴、保護最好的雲存儲

MEGA is a cloud storage service focused on security that offers users excellent end-to-end encryption and a great free plan with tons of storage. However, its history has been marked by controversy and its zero-knowledge-encryption makes collaboration difficult. Find out more about MEGA, both the good and the bad, in this full MEGA review.

Key Takeaways:

  • MEGA offers one of the best free plans on the market: 20GB free excellent free plan.
  • User data and files are secure through its zero-knowledge encryption service.
  • Robust security means fewer options for effective collaboration.

Founded in 2013 as a successor to the infamous Megaupload — which you can read more about in our guide to what Megaupload is — MEGA cloud storage was created by the notorious Kim Dotcom. Following the takedown of Megaupload’s servers in Hong Kong, MEGA was incorporated in New Zealand as a cloud service dedicated to the security and privacy of its users’ data.

In spite of all its controversy, MEGA is still a very secure cloud service, and it’s one of the best choices for anyone looking for lots of free storage space. A free account will get you a whopping 20GB of cloud storage. Because of this, MEGA makes our list of the best free cloud storage services.

Although MEGA has a generous free plan, its paid plans are rather pricey and it doesn’t really offer enough cloud storage to make up for the price. There are certainly better alternatives that offer much more storage for a lower price. You can check out our review of Sync.com if you’re looking for a deal that offers top-notch security for a great price.

  • Despite its controversial past, MEGA is as trustworthy as any other leading cloud storage provider. It’s transparent about your privacy and even extends GDPR protection to users worldwide.

  • MEGA is not an illegal service and complies with all regulations that apply to a service of its type. It also has a dedicated support team to help take down any files that may be an infringement of copyright law.

  • MEGA does not give viruses through its software across all its platforms. However, like with any other cloud service, users should only download files sent to them from trusted sources to avoid viruses and malicious malware.

  • MEGA certainly outperforms Google Drive in relation to privacy and security. However, Google is a far better option for those looking for a cloud service that offers robust tools for collaboration.

MEGA Review: Alternatives

MEGA Strengths & Weaknesses

Pros:

  • Zero-knowledge encryption
  • Encrypted sharing links
  • Plenty of free storage
  • Previews for media & documents

Cons:

  • High prices for paid plans
  • Not good for collaboration
  • Poor customer support
  • User experience could be better

Features

80 % – Good

MEGA’s outstanding feature is its end-to-end encryption. All files that are uploaded to MEGA’s servers are encrypted on the side of the client, meaning the user is the only one who can decrypt their own data. Along with two-factor authentication, this makes for a very secure cloud storage service.

Apart from the excellent security, MEGA has plenty of features — some necessary, others not so much. It has several sharing features plus some nice extras, like the chat client. However, it lacks integration with third-party apps, so it’s not the best for collaboration, leaving some users turning to the likes of Google Drive and OneDrive (read our Microsoft OneDrive review).

MEGA provides a detailed overview to help you manage your storage.

What Is MEGA Used For?

MEGA is a secure cloud service that offers robust sharing features. It’s extremely useful for sharing sensitive data, with several layers of protection for your shared links. Everything uploaded to MEGA is encrypted with an individual encryption key, which can be sent separately. However, only paid users can set expiration dates and passwords for the links.

mega sharing encryption

Paid users can set unique passwords and expiry dates when sharing files. 

You can also share folders with anyone with a MEGA account. Sharing folders this way lets you set permissions for the folder, allowing you to choose who can upload to the shared folder, or alter any data inside it.

MEGA’s interface can be a little cluttered at times, and there’s a lot of overlap between its many features, especially when it comes to file sharing. In comparison, Tresorit is a secure cloud storage service that makes file sharing much easier and less confusing for the user. You can read more about Tresorit and its excellent sharing features in our Tresorit review, and also read our MEGA vs Tresorit comparison.

MEGA for Productivity and Collaboration

MEGA also offers a slew of apps, ranging from the standard desktop and mobile apps to live chat to dedicated apps for sharing large files.

mega live chat

Users can communicate via the live chat feature directly inside the MEGA web app.

The live chat functionality can be useful for collaboration, as it is also secured by MEGA’s encryption protocol. However, keep in mind that metadata, such as the email address of your contact, remains unencrypted. Chat is available both through the MEGA website and via the mobile app.

You can share files inside the chat, either directly from your computer or from your MEGA cloud drive. There are no file previews when sharing inside the chat, so you’ll need to remember the file name. It’s a tiny bugbear, but something MEGA could certainly improve on.

MEGA also retains previous versions of any file you have uploaded, so it’s safe from any accidental changes saved to the cloud. Versioning is enabled by default, and files with previous versions are marked with a little clock icon next to them.

Unfortunately, MEGA’s strong focus on privacy and security doesn’t leave much room for collaboration options, so integration with third-party apps like Google Docs is impossible. If you need to collaborate on cloud-based files, Google Drive is one of the best options for that.

mega image preview

MEGA allows users to preview hi-res images inside the web application. 

MEGA’s file management system is fairly comprehensive, with separate tabs for recent and deleted files, incoming and outgoing shares, as well as a storage management tab where you can view statistics about your cloud storage use. You can also preview images, music and video files and PDF documents.

There’s also a feature called MEGAcmd that allows you to use a command-line interface for advanced management of your personal cloud. Using MEGAcmd and MEGA’s WebDAV integration, you can set up things like scheduled uploads or automatic backups.

Free Plan

Pricing

80 % – Good

The main draw of MEGA is its excellent free plan that comes with 20GB of storage and a generous transfer quota. Additionally, MEGA has four paid plans and a separate business plan. However, these plans are pretty costly and don’t offer any crucial features, so unless you need the larger amounts of storage they offer, there’s not much incentive to upgrade.

Pro Lite

  • : File transfer: (monthly plan) 12TB (yearly plan)
  • : 400 GB

Pro I

  • : File transfer: 2TB (Monthly plan) 24TB (yearly plan)
  • : 2000 GB

Pro II

  • : File transfer: (monthly plan) 96TB (yearly plan)
  • : 8000 GB

Pro III

  • : File transfer: 16TB (monthly plan) 192TB (yearly plan)
  • : 16000 GB

Business

  • : Up to 10PB
  • : 10485760 GB

The prices above are in U.S. dollars, conversions from MEGA’s pricing in euros.

Free Account Features

The free plan offers most of MEGA’s functionality, with exceptions such as time limits and passwords for links, longer retention periods for deleted files and the ability to grant your monthly transfer quota to other accounts.

It comes with 20GB of permanent storage, which is already among the most generous free plans. On top of that, there are several ways of expanding your storage.

Installing MEGAsync, MEGA’s desktop app, will get you 5GB of bonus storage. You can get an additional 5GB for installing the mobile app and 5GB for verifying your phone number. These bonuses, totaling 15GB, last for 365 days.

You can also nab an additional 5GB of bonus storage for each friend you invite to MEGA. Each confirmed referral gets you a bonus that lasts for a whole year, so you can easily expand your storage when you need it, at no cost to you.

Do not worry if you don’t see your bonus storage appear immediately. MEGA will send an email notification that your bonus storage is available, but may take a few days to appear on your account. 

It’s worth noting that free accounts are subject to transfer limits, but the exact amount is non-specific and usually resets every 24 hours. It’s also determined by your IP address, so in the worst-case scenario you can just connect to MEGA through a VPN.

If you think a free account with MEGA is not for you, you can check out Icedrive, another privacy-minded cloud service with an excellent free plan that includes 10GB of storage.

mega achievements

Users can bag additional free storage spaces by downloading MEGA’s apps and referring friends. 

The cheapest upgrade to your MEGA cloud storage account is the Pro Lite plan. It comes with 400GB of cloud storage and 1TB of transfer for a monthly price of $5.85 (4.99 euros). You can also choose to pay a yearly fee, which will bring your tally up to $58.59 (49.99 euros).

Next up is the Pro I plan, which costs $11.71 (9.99 euros) per month or $117.19 (99.99 euros) yearly. It offers 2TB of cloud storage and a 2TB transfer quota.

The Pro II plan comes in at $23.43 (19.99 euros) per month or $234.39 (199.99 euros) per year. This gets you 8TB of cloud storage and a monthly transfer quota of 8TB.

The most expensive plan is the Pro III plan, which costs $35.15 per month (29.99 euros), and it comes with 16TB of transfer and storage space. If you opt for a business account, you get unlimited cloud storage and transfer for the monthly price of $5.86 (5 euros) per user, with a minimum of three users.

These plans aren’t the cheapest around. pCloud is more affordable, and it’s an excellent cloud storage service overall. You can read our full pCloud review for more information.

Ease of Use

80 % – Good

MEGA’s interface design seems a little dated by today’s standards, with its bold reds and dark contrasting grays. This does help a lot with legibility, though, making everything easy to notice and read. MEGA added a dark mode in 2021, which makes it a little easier on the eyes at night.

mega dark mode

You can use MEGA in dark mode for better viewing in low-light situations.

MEGA offers several apps that let users access the service in different ways. There are the two desktop apps we mentioned, as well as mobile apps for Android and iOS. The browser experience is handled either through the MEGA.io (formerly MEGA.nz) website or the dedicated add-on for Google Chrome and Mozilla Firefox. MEGAcmd further expands MEGA’s feature set.

mega desktop client

Users can sync folders and drag and drop files to their MEGA cloud storage directly from their desktop.

MEGA in the Browser

The browser interface is the main way of using MEGA, and it’s where you’ll find all the necessary tools. There are several tabs to the left for easy navigation, but you’ll be spending most of your time using the “cloud drive” tab. This tab has a navigator on the left side that shows your cloud drive’s folder structure, and your files are displayed on the right side of the screen.

From here you have access to all your files. You can right-click any file or folder to manage sharing links or to move, copy or delete them, plus you can download or preview them. You can use the “file upload” or “folder upload” buttons to upload data to your MEGA cloud storage, but you can also just drag and drop them into the browser window to upload.

mega sync folder

MEGA creates a sync folder for files uploaded from your desktop.

MEGA Desktop and Mobile Apps

The desktop experience is mainly handled through the MEGAsync app. Installing the app creates a MEGA folder on your computer where all your data is synced. While installing the app, you can choose whether to sync all folders or only select folders.

The MEGAsync app appears as a taskbar icon on Windows. The app functions mainly as a transfer manager that allows you to upload and download files and folders, as well as manage your synced folders. It also lets you stream files while your computer is online, functioning like a peer-to-peer service.

mega mobile app

MEGA has an easy-to-use mobile app; however, it’s lacking some basic functionality.

One small issue with the app is that there is no “back” button, meaning that whenever you open a menu, you have to click away and then reopen the app from the taskbar. That can get annoying really fast if you have a lot of work to do in the app.

The mobile app functions just like any other mobile cloud service app. You can upload and download files, send links and move files around. Turning on “media upload” will automatically upload your photos and videos to MEGA, and MEGA’s chat feature is also accessible through the mobile app.

Usability Issues

Since its launch, MEGA has added a ton of features, but neither the interface nor existing features have been updated accordingly. This has created some overlap between features that can leave users confused about which app to install or which sharing feature to use.

You can’t create upload links for folders, but you can turn them into MEGAdrop folders, which lets anyone with the link upload to it. However, you can’t share download links for MEGAdrop folders without them reverting to regular folders. This could have been resolved by simply allowing the user to create upload links.

All the clutter is especially visible when comparing the service to Dropbox, which has one of the most polished user experiences for a cloud storage service. You can find out more about it in our Dropbox review. It’s one of the easiest cloud services to use and is a departure from MEGA’s cluttered interface. 

If you’ve had trouble using MEGA’s service, you can read our guide for a detailed look at how to use MEGA.

You can access the settings menu through the system tray (Windows) or the menu bar (macOS).

File Sharing & Syncing

90 % – Excellent

MEGA offers a full file-sharing feature set, with only some minor things missing. There are many ways to share files and folders and even some interesting and unique features that the competition doesn’t offer.

The main way of sharing files is by sending links, which you can create with the “get link” option. Each link is encrypted, and the encryption keys can be sent separately. Plus, you can set passwords and expiration dates for links to make them more secure.

You can also use the “sharing” option to share files, but this is more useful for folders because it lets you set permissions for different users. You can set an individual recipient’s permissions to “read only,” “read and write” or “full access.” However, you can only share things with someone who has a MEGA account.

To let someone without a MEGA cloud storage account upload to your folder, you can turn that folder into a MEGAdrop folder. This will let anyone with the MEGAdrop folder’s link upload to it.

The only things missing from MEGA’s sharing functionality are setting download limits for links and restricting individual users from accessing linked files, though the encryption keys and password protection should take care of the last part well enough.

mega folder sharing

Users can share folders with both internal and external users, and set user permissions.

MEGA Sync

The MEGAsync app creates a sync folder on your hard drive, and this is where all your files are synced. You can choose which folders to sync, and you can even sync existing folders to your MEGA cloud storage account.

mega drop file sharing

MEGAdrop allows external users to add to and download files from a shared folder.

Syncing folders is easy and it’s done via the desktop app’s system tray icon. You can select which folder to sync by clicking the “sync” option in the app’s dot menu, and then selecting “add sync.” You can then choose a folder from your hard drive to sync to the cloud, and choose which folder on your MEGA cloud account to sync to, or you can create a new cloud folder for it.

MEGA doesn’t offer block-level sync though, which means that an altered file will have to be reuploaded in its entirety, instead of only the parts that changed. This makes syncing data slightly slower than some competitors.

Speed

75 % – Good

In previous versions, MEGA had disappointing upload and download speeds. Thankfully, things have improved with the latest versions of the application. As with all our cloud storage tests, we uploaded a 5GB folder of mixed files using a 100 Mbps connection for both uploads and downloads.

In previous tests, it took 24 minutes to upload a 1GB folder. It’s refreshing to see MEGA has greatly improved on those performance times for uploads, especially now that we’re uploading a much larger folder. Download speeds are not necessarily anything to write home about, but they are passable. 

First attempt: Second attempt: Average:
Upload 0:08:38 0:08:50 0:08:44
Download 0:08:10 0:07:14 0:07:42

Is MEGA super quick? No. But its improved performance means that we can now recommend it to those who put speed toward the top of their list of cloud storage needs. However, if you’re looking for an all-round speed demon, you should consider Dropbox, which offers some of the best performance in the space (check out our full Dropbox review).

MEGA has improved its performance in terms of speed, making it a more attractive option.

Security

98 % – Excellent

Security is what MEGA prides itself on, and it’s one of its best features. MEGA is one of only a handful of cloud storage services that provide end-to-end, zero-knowledge encryption. The best part is that it offers its encryption services at no cost at all, unlike most other storage services.

MEGA encrypts all of your data client-side, so you are the only one holding the encryption keys. This means that neither MEGA nor any malicious actor has a way to access your data without your consent.

The encryption protocol that MEGA uses is the standard 128-bit AES encryption for your at-rest files, and it encrypts your data in transit using the TLS protocol, also with 128-bit AES. This means that your files are secure on the MEGA servers and while being uploaded or downloaded, so your data is safe from man-in-the-middle attacks.

MEGA uses two-factor authentication to add an extra layer of security for your login. This means that even someone with your account data will not be able to log in to your account and compromise your private data.

MEGA should be a safe place to store all of your private data because the client-side, end-to-end encryption ensures the privacy of your files, even if someone gains access to your data. All of this makes the MEGA cloud service very secure.

With this level of security, MEGA is unable to reset your password should you forget what it is. However, you can recover your account by downloading a recovery key. We recommend you do this and keep it safe, so you can access your account if you forget your password.

It’s important to download your recovery key for access to your account if you lose your password.

Privacy

85 % – Very Good

Privacy is where things get a little tricky with MEGA. Most users will have nothing to fear and their data should be safe with MEGA. However, MEGA’s sordid past has been mired in controversy from the day it was founded, and its relation to “pirate king” Kim Dotcom can be worrying for some.

MEGA’s servers are located in Canada, New Zealand and several European Union countries. This means that MEGA has to comply with the GDPR, a law that protects your data. MEGA further extends GDPR protections to all of its users, even those residing outside of the EU.

MEGA has spread out its server network like this to prevent a government of any single country issuing a takedown of its servers, as a precautionary measure to avoid something like what happened to its predecessor, Megaupload.

Is MEGA Safe to Use?

MEGA is a safe service to use. However, there are some points about user data that you should be aware of. 

Its privacy policy states the service may hand over user data to advertisers, but the user will remain anonymous. That’s similar to how the likes of Google and Microsoft operate, as well as some other organizations. If you’re not overly concerned about your data potentially being handed over to third-parties then this won’t be an issue.

MEGA never has full access to your data, owing to its client-side encryption. Plus, even if MEGA was forced by law to hand over your data, it is all encrypted by its zero-knowledge service. 

However, MEGA does hold onto some metadata about your MEGA usage, including:

  • The IP addresses of the devices you use to access MEGA
  • Browser types and operating systems of those devices
  • File sizes, versioning order and parent-child relationships
  • Various timestamps, such as when files are created or deleted
  • The email address of anyone you have contacted on MEGA, including people you’ve added as contacts and people you’ve shared data with via MEGA’s sharing function
  • The email address of anyone you’ve contacted using MEGA’s chat system
  • Takedowns and account suspensions
  • MEGA’s communications with you
  • Your account settings, including your avatar

This data doesn’t amount to much, but it’s enough to discern whether a user is breaking MEGA’s terms of service or any copyright laws. 

MEGA, Kim Dotcom and China

MEGA.nz was founded by Kim Dotcom in 2013. Since leaving the company in 2015, he has made claims that MEGA has been taken over by a Chinese investor, William Yan, who is wanted in China for fraud. Whether this is accurate has yet to be determined, but it’s something to be aware of, as some may not wish to use a service that’s covered with controversy. 

It’s also important to note that a large portion of MEGA’s shareholders are influenced by or connected to the Chinese government. China is notorious for its lack of interest in protecting people’s privacy. Again, no wrongdoing has been confirmed, but it’s worth having these concerns on your radar.

Luckily, all of your files are encrypted, so not even MEGA can actually access your sensitive data. This means you should have no worries about China’s president looking at your cat pictures.

Customer Support

75 % – Good

MEGA is somewhat lacking in the customer service department. It has a help center for frequently asked questions, but if you can’t find an answer there, you can contact customer support via email.

You can use the help center to find answers to most questions, which are neatly categorized into sections about the various apps and services and further divided into topics. The help center is fairly comprehensive, and there are image guides for most articles there.

mega customer support

MEGA’s customer support is limited. However, it does have an extensive help center that covers most issues.

The only way to actually contact a customer service representative is through email. Though MEGA offers 24/7 email support, response times can vary. It claims to respond within 24 hours, but a whole day of waiting may be too much for some users. We received a response within six hours of sending our test query. 

Also missing from its customer support service are phone support and a forum where users can discuss issues among themselves, and live chat would be a welcome addition. MEGA could learn a thing or two from Google Drive, which has a wealth of customer support options available at all times.

The Verdict

Despite all the drama surrounding it, MEGA remains a solid cloud storage service. With its strong dedication to privacy and security, it is one of the safest cloud services around. Plus, all of its security features are available for free, so you don’t have to pay extra for its encryption services.

MEGA’s free plan is very generous, with an upgradeable 20GB of storage, making it one of the best free cloud services. It lacks only some minor features, and its ample storage is enough to satisfy most users’ needs.

However, if you need more storage than the free plan offers, MEGA’s prices can be prohibitive. You may be better off with a service like Sync.com, which offers much of MEGA’s functionality at a lower price and without the attached controversy.
