In today’s digital age, we’re constantly bombarded with terms like megabytes, gigabytes, and terabytes. These units of storage capacity are crucial for managing our digital lives, whether it’s backing up cherished photos or navigating enterprise-level data solutions. Especially as we inhabit a world generating colossal amounts of data – projected to reach a staggering 149 zettabytes in 2024 and expected to double by 2028 – understanding these units is more important than ever.
This article will demystify file sizes and explore the relationship between gigabytes (GB) and terabytes (TB), the units you’ll frequently encounter when dealing with storage for your devices or online services. We’ll also touch upon different storage types, from physical drives to cloud solutions, and introduce a seamless way to manage files of any size.
Decoding Data Storage Units: Bytes, KB, MB, GB, TB
At the heart of digital data is the byte. Think of it as the fundamental building block. A byte is composed of 8 bits, with each bit representing a binary digit – either 0 or 1. These bits are the bedrock for storing all forms of digital information, be it text documents, vibrant images, clear audio, or high-definition videos.
While a byte is the basic unit, in practice, you’ll rarely encounter storage measured in just bytes. As data needs grew, we scaled up to larger units. This is where kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB) come into play. These are the units you’ll most often see when shopping for a new computer, smartphone, or external hard drive, or when managing your digital files online.
To grasp the scale, imagine storage units as volumes of water. A kilobyte is akin to a tiny sip, a gigabyte is like a full glass, and a terabyte? That’s comparable to an Olympic-sized swimming pool!
Storage units don’t stop at terabytes. They extend even further, reaching units like zettabytes and yottabytes. A yottabyte, the largest currently defined unit, is so vast it could theoretically store every book, video, song, image, and document ever created by humankind – or equivalently, 1,000 zettabytes, which itself equals one billion terabytes.
Decimal vs. Binary: The GB to TB Discrepancy
Have you ever noticed that a 1 TB hard drive you purchased seems to show up as less than 1 TB on your computer, perhaps closer to 900 GB? This isn’t an error; it’s due to the difference between decimal and binary systems in measuring storage.
Hard drive manufacturers often use the decimal system, also known as the SI (International System of Units) standard. In this system, storage is calculated in powers of 10. So, when a manufacturer labels a drive as 1 TB, they mean 1,000 GB (1 TB = 1,000,000,000,000 bytes). This aligns with how we generally use metric prefixes like kilo, mega, and giga.
However, computers typically operate using the binary system, calculating storage in powers of 2. This system, defined by JEDEC (Joint Electron Engineering Council) for memory like RAM and flash storage, defines 1 KB as 1,024 bytes, 1 MB as 1,024 * 1,024 bytes (1,048,576 bytes), and so on.
To clarify this potential confusion, the IEC (International Electrotechnical Commission) introduced binary prefixes like kibi (KiB), mebi (MiB), gibi (GiB), and tebi (TiB). Using these prefixes, 1 kibibyte (KiB) is precisely 1,024 bytes, differentiating it from the decimal kilobyte (KB) which is 1,000 bytes.
Despite these IEC prefixes, many operating systems still report storage using the JEDEC binary system with decimal prefixes (KB, MB, GB, TB) because they are more widely recognized. Thus, when you connect that 1,000 GB decimal-based hard drive to your computer, which interprets storage in binary, it will display approximately 931 GiB (or what’s often shown as GB) – creating the perception of less capacity, even though the actual storage amount is the same.
Here’s a table summarizing the difference:
| Unit | SI Standard (Decimal) | JEDEC Standard (Binary) |
|---|---|---|
| Terabyte | 1,000 gigabytes | 1,024 gigabytes |
| Gigabyte | 1,000 megabytes | 1,024 megabytes |
| Megabyte | 1,000 kilobytes | 1,024 kilobytes |
| Kilobyte | 1,000 bytes | 1,024 bytes |
At Proton Drive, we use the JEDEC binary system. Therefore, when you subscribe to 1 TB of cloud storage with us, you are actually receiving 1,024 gigabytes of storage space to safeguard your files, photos, and important documents.

How Much Storage Do You Actually Need?
Determining your ideal storage capacity hinges on what you intend to store. Different file types vary significantly in size, so your needs will depend on the volume and nature of your data. Someone backing up hours of high-definition videos will require considerably more space than someone primarily storing text documents.
Personal Storage Needs: For individuals, storage requirements often revolve around backing up personal memories and documents:
- 5 to 20 GB: Suitable for occasional storage of text files, documents, photos, and a few short videos.
- 50 to 200 GB: Ideal if you regularly store photos and videos, maintain a digital music library, or have a collection of software applications.
- 500 GB to 2 TB: Necessary for those who frequently work with HD or 4K videos, high-resolution photography, large design files, or extensive media libraries.

Business Storage Needs: For businesses, storage needs scale with the size of the organization and the type of data handled:
- 50 GB to 500 GB: May suffice for small businesses managing documents, presentations, spreadsheets, and basic file sharing among a small team.
- 500 GB to 1 TB: Better suited for teams or departments within medium-sized businesses that handle more data-rich projects and collaborative files.
- 1 TB or more per employee: Often required for businesses dealing with large datasets, technical files, video production, or extensive client data.

Storing and Sharing Terabytes of Data: Physical vs. Cloud
When it comes to storing and sharing large amounts of data, particularly terabytes, you have options ranging from physical devices to cloud storage.
Physical Storage
Historically, physical storage devices like external hard drives, SSDs, and USB drives were the primary method for storing and transporting files. They offer the tangible aspect of keeping your data “in your hands.” However, they come with limitations. Physical drives have fixed capacities, so expanding storage often means purchasing new hardware, which can become costly as your data grows into megabytes and terabytes.
Sharing data on physical devices can also be cumbersome and risky. Physically transporting a drive exposes it to the risk of damage, loss, or theft, potentially compromising your data. While email is an option for sharing, most email providers impose file size limits, typically around 25 MB, making it impractical for large files.
Cloud Storage
Cloud storage, in contrast, provides unparalleled convenience and scalability. Services like Proton Drive allow you to start with a modest amount of storage and seamlessly expand as your needs increase, without the need for physical hardware upgrades.
Cloud storage excels in collaboration. It enables easy access and sharing of files with colleagues or clients, regardless of geographical location. With Proton Drive, there are no file size restrictions, making it ideal for sharing terabytes of data securely, eliminating the risks associated with physical media.

FAQ
How much data can a terabyte hold?
A terabyte (TB) is a substantial unit of digital storage. Practically, 1 TB can accommodate roughly 250,000 photos at 4MB each or numerous software backups, depending on their individual sizes. Proton Drive empowers businesses to enhance teamwork by providing 1 TB of storage per team member, while individual users can access 1 TB of secure storage for just $14.99 per month.
Does 1 TB hold 1,000 GB or 1,024 GB?
The capacity of a terabyte (TB) depends on the measurement system used. In the decimal system, common among hard drive manufacturers, 1 TB equals 1,000 GB. However, in the binary system, used by computers for memory measurement, 1 TB is equivalent to 1,024 GB. Proton Drive adheres to the binary system as defined by JEDEC, ensuring that 1 TB of Proton Drive cloud storage provides you with 1,024 GB of actual storage space.
Does Proton Drive have limits on files I can upload or share?
Proton Drive does not impose any file size limits for uploads or sharing. This makes it exceptionally well-suited for handling large files like high-resolution videos, extensive datasets, or comprehensive photo libraries. Your total usable storage is determined by your subscription plan. A free Proton Drive account starts you with 5 GB of storage, and paid personal plans offer significantly larger capacities, up to 1 TB, depending on your chosen plan.
