Backblaze B2 vs MEGA: Which Should You Buy?

If you’ve been in the home-lab game as long as I have, you know that your local RAID array is not a backup—it’s just fast storage. The real nightmare begins when you realize your “safe” data is all under one roof. To truly sleep at night, you need an off-site target.

Depending on how you build your stack, you’re usually looking for one of two things: a raw bucket to dump snapshots into via your NAS, or a user-friendly cloud drive where you can toss files and share them. That brings us to Backblaze B2 and MEGA. These are fundamentally different animals—one is object storage designed for machines, the other is cloud storage designed for people.

The Analysis: Infrastructure vs. Interface

When we talk about “storage,” the terminology gets muddy. To clear it up: Backblaze B2 is object storage. In my experience, this means it doesn’t behave like a folder on your computer; it behaves like an API endpoint. If you are running a professional-grade NAS or using backup software that supports S3-style targets, this is the gold standard for keeping costs predictable while ensuring your data exists in a different zip code.

MEGA, conversely, falls into the traditional cloud storage category. It’s built around an interface and user experience. You aren’t typically scripting API calls to MEGA; you’re dragging and dropping files or using their client to sync folders. For the hobbyist who doesn’t want to manage a complex backup pipeline but still wants encrypted storage, this is the path of least resistance.

The Cost Conversation: TBs vs. Flat Rates

The pricing models here represent two completely different philosophies. Backblaze B2 uses a utility-based model at $6/TB/mo. This is ideal for those of us who scale our data organically. You pay for what you use, which makes it incredibly efficient if your backup footprint is small but grows over time. However, the “gotcha” here—and one every home-labber needs to account for—is egress fees. Moving data in is usually fine, but pulling large amounts of data out will cost you.

MEGA takes a more traditional subscription approach at $11/mo. The real draw here isn’t the paid tier, though; it’s the entry point. They offer 20GB for free, which is significantly more generous than most of the industry. It’s perfect for those who just need to store critical documents and small configuration files without opening a wallet. The trade-off? Bandwidth caps. If you try to move massive datasets in short windows, you’ll hit a wall.

Pros & Cons

Backblaze B2

Pros:

• Cheap: Very competitive pricing for those scaling their storage.
• Simple: No-nonsense deployment.
• NAS-native: Plays incredibly well with existing home-server hardware and backup suites.

Cons:

• Egress fees: You have to be mindful of how often you pull data back from the cloud.

MEGA

Pros:

• 20GB Free: One of the best free tiers available for getting started.
• Encrypted: Built-in encryption provides peace of mind for sensitive files.

Cons:

• Bandwidth caps: Not suitable for high-velocity data transfers or massive daily syncs.

Which should you buy?

The choice here isn’t about which product is “better,” but rather where it sits in your architecture.

Choose Backblaze B2 if you are building a professional backup pipeline. If you have a NAS and want to set up an automated, S3-style off-site target that just works in the background, this is the correct choice. It’s built for the “set it and forget it” mentality of infrastructure management, provided you can handle the egress costs if a total disaster recovery scenario occurs.

Choose MEGA if you want a versatile cloud drive. If you don’t have a dedicated server and just need a secure place to store files across multiple devices—or if you are operating on a zero-dollar budget and want to take advantage of that 20GB free tier—this is your winner. Just be aware that the bandwidth caps make it less ideal for multi-terabyte archival dumps.

FAQ

What is the difference between object storage and cloud storage? Object storage, like Backblaze B2, stores data as objects with metadata and is typically accessed via APIs, making it ideal for machine-to-machine backups. Cloud storage, like MEGA, usually presents a file/folder hierarchy designed for human interaction and direct file synchronization.

Does MEGA offer a free version? Yes, one of the primary draws of MEGA is its generous 20GB free tier, making it an excellent choice for users with smaller storage needs.

Are there hidden costs with Backblaze B2? While the monthly cost per TB is low ($6/TB/mo), you should be aware that egress fees apply when retrieving data from their servers.

Can I use these as a direct replacement for my local hard drives? Generally, no. Both are SAAS products designed for off-site redundancy or cloud access. Due to bandwidth caps on MEGA and egress fees/latency on Backblaze B2, they should be used as secondary backup targets rather than primary working drives.
