A gigabyte (GB) is a unit of digital information storage equal to 10⁹ bytes (one billion bytes). It uses the standard SI decimal prefix 'giga-'. One gigabyte is equivalent to 1,000 megabytes (MB).
Precise definitions:
- 1 gigabyte (GB) = 1,000,000,000 bytes (exactly 10⁹)
- 1 GB = 1,000 megabytes (MB)
- 1 GB = 1,000,000 kilobytes (KB)
- 1 GB = 8,000,000,000 bits (8 billion bits)
- 1 GB = 0.001 terabytes (TB)
Relationship to binary units:
- 1 gigabyte (GB) ≈ 0.9313 gibibytes (GiB)
- 1 gibibyte (GiB) = 1,073,741,824 bytes = 2³⁰ bytes
- 1 GiB ≈ 1.074 GB (7.37% larger)
Gigabyte (GB) vs. Gibibyte (GiB): Critical Distinction
This is the source of the infamous "missing storage" confusion:
Gigabyte (GB) — Decimal prefix:
- Exactly 1,000,000,000 bytes (10⁹)
- Based on SI standard (powers of 10)
- Used by storage manufacturers (hard drives, SSDs, USB drives)
- Used for data transfer rates, internet speeds, data plans
- Marketing and advertising standard
Gibibyte (GiB) — Binary prefix:
- Exactly 1,073,741,824 bytes (2³⁰)
- Based on binary powers (powers of 2)
- Used by Windows, Linux, macOS for storage reporting
- Used in RAM specifications (though often mislabeled as "GB")
- Technical documentation standard
Why your "500 GB" drive shows as "465 GB" in Windows:
- Manufacturer's claim: 500 GB = 500,000,000,000 bytes
- Windows calculation: 500,000,000,000 ÷ 1,073,741,824 = 465.66 GiB
- Windows displays this as: "465 GB" (but actually means 465 GiB)
- Result: Appears to have "lost" 35 GB, but it's just a unit conversion
Percentage difference: GiB is 7.37% larger than GB, so the gap widens with larger capacities:
- 100 GB = 93.13 GiB (6.87 GB "missing")
- 500 GB = 465.66 GiB (34.34 GB "missing")
- 1 TB = 931.32 GiB (68.68 GB "missing")
- 2 TB = 1,862.65 GiB (137.35 GB "missing")
Gigabyte (GB) vs. Gigabit (Gb): Don't Confuse Them!
Another critical distinction:
Gigabyte (GB):
- Measures storage capacity (data at rest)
- 1 GB = 1,000,000,000 bytes
- Used for: file sizes, storage devices, data plans
- Symbol: GB (capital B for Byte)
Gigabit (Gb or Gbit):
- Measures data transfer speed (data in motion)
- 1 Gb = 1,000,000,000 bits
- Used for: network speeds, internet connections
- Symbol: Gb or Gbit (lowercase b for bit)
- 1 gigabyte = 8 gigabits (since 1 byte = 8 bits)
Real-world example:
- 1 Gbps (gigabit per second) internet connection can theoretically download at 125 MB/s (megabytes per second) or 0.125 GB/s
- Calculation: 1 Gbps ÷ 8 = 0.125 GB/s
- In practice: Overhead reduces this to ~100-115 MB/s actual download speed
An exabyte (EB) is a unit of digital information storage equal to 10¹⁸ bytes (one quintillion bytes). It uses the standard SI decimal prefix 'exa-'. One exabyte is equivalent to 1,000 petabytes or 1,000,000 terabytes.
Precise definitions:
- 1 exabyte (EB) = 1,000,000,000,000,000,000 bytes (exactly 10¹⁸)
- 1 EB = 1,000 petabytes (PB)
- 1 EB = 1,000,000 terabytes (TB)
- 1 EB = 8,000,000,000,000,000,000 bits (8 exabits)
Relationship to binary units:
- 1 exabyte (EB) ≈ 0.867 exbibytes (EiB)
- 1 exbibyte (EiB) = 1,152,921,504,606,846,976 bytes = 2⁶⁰ bytes
- 1 EiB ≈ 1.1526 EB (15.26% larger)
Exabyte (EB) vs. Exbibyte (EiB): Massive Scale Distinction
At exabyte scale, even small percentage differences matter enormously:
Exabyte (EB) — Decimal prefix:
- Exactly 1,000,000,000,000,000,000 bytes (10¹⁸)
- Based on SI standard (powers of 10)
- Used by cloud providers, data centers, global statistics
- Standard for internet traffic and data creation metrics
Exbibyte (EiB) — Binary prefix:
- Exactly 1,152,921,504,606,846,976 bytes (2⁶⁰)
- Based on binary powers (powers of 2)
- Used by technical specifications, scientific computing
- Standard for certain supercomputing and research contexts
Why the 15% difference is critical:
- 1 EB = 0.867 EiB (significant difference)
- Data center planning: 100 EB = 86.7 EiB of actual capacity
- Scientific datasets: Precision matters for resource allocation
- Global statistics: Internet traffic measured in EB (decimal)
Exabyte (EB) vs. Exabit (Eb): Global Data Distinction
Another critical distinction at massive scale:
Exabyte (EB):
- Measures storage capacity (data at rest)
- 1 EB = 1,000,000,000,000,000,000 bytes
- Used for: cloud storage, data centers, archives
Exabit (Eb or Ebit):
- Measures data transfer (data in motion)
- 1 Eb = 1,000,000,000,000,000,000 bits
- Used for: network capacity, global internet bandwidth
- 1 exabyte = 8 exabits (since 1 byte = 8 bits)
Real-world example:
- Global internet traffic: ~200 EB annually
- Network capacity: Measured in Eb/s (exabits per second)
Note: The Gigabyte is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Exabyte belongs to the imperial/US customary system.
History of the Gigabyte and Exabyte
The prefix 'giga-' (meaning billion) was adopted as an SI prefix in 1960. Its application to the byte (gigabyte) became widespread with the increasing capacity of computer storage media like hard drives in the 1980s and 1990s.
The "Giga-" Prefix Origins (1960)
International standardization:
1960: 11th General Conference on Weights and Measures (CGPM):
- Officially adopted "giga-" as the SI prefix for one billion (10⁹)
- Derived from Greek "γίγας" (gigas) meaning "giant"
- Part of the expanded SI prefix system: kilo (10³), mega (10⁶), giga (10⁹), tera (10¹²)
Scientific context before computing:
- Originally used in physics and engineering (gigahertz, gigawatt, gigajoule)
- Computing adopted SI prefixes as storage capacity grew
Early Gigabyte Storage (1980s-1990s)
When gigabytes became practical:
1985: IBM 3380 Direct Access Storage Device:
- First mainstream storage system with multi-gigabyte capacity (up to 2.52 GB per unit)
- Used by mainframe computers
- Cost: Approximately $100,000+ per unit
- $40,000-$50,000 per gigabyte
1991: IBM 0663 Corsair:
- First consumer hard drive exceeding 1 GB (1.05 GB capacity)
- 3.5-inch form factor
- Price: $2,799 (approximately $2,665 per GB)
- Revolutionary for personal computing—suddenly PCs could store hundreds of applications
1997: Hard drive prices drop below $1,000/GB:
- Typical 4 GB drive: $300-$400 ($75-$100 per GB)
- Enabled multimedia computing (video editing, game installations)
Late 1990s: CD-ROMs reach 650-700 MB:
- A single CD held 0.65-0.7 GB
- Software distribution moved from floppy disks (1.44 MB) to CDs
- Games and applications could be hundreds of megabytes
The GB vs. GiB Ambiguity Crisis (1960s-1998)
Decades of confusion:
The root problem: Computer memory uses binary addressing (powers of 2), but SI prefixes are decimal (powers of 10).
1960s-1990s: Binary interpretation becomes common:
- Computer scientists used "kilobyte" = 1,024 bytes (2¹⁰), not 1,000
- "Megabyte" = 1,048,576 bytes (2²⁰), not 1,000,000
- "Gigabyte" = 1,073,741,824 bytes (2³⁰), not 1,000,000,000
- Rationale: Memory addresses are binary, so powers of 2 made sense
1980s-1990s: Storage manufacturers use decimal:
- Hard drive makers used 1 GB = 1,000,000,000 bytes (exact SI definition)
- Marketing advantage: Decimal prefixes made drives appear larger
- Example: 100 billion bytes marketed as "100 GB" (decimal) showed as "93.13 GB" in Windows (binary)
Consumer confusion and lawsuits:
- "Missing storage" complaints: Consumers felt deceived when drives appeared smaller than advertised
- 2006: Western Digital lawsuit: Settled for marketing "400 GB" drives that showed as 372 GB in Windows
- Apple, Seagate, others: Similar lawsuits alleging deceptive marketing
IEC Binary Prefix Solution (1998-Present)
Official standardization to end confusion:
1998: IEC introduces binary prefixes (IEC 60027-2 standard):
- Kibibyte (KiB) = 1,024 bytes (2¹⁰)
- Mebibyte (MiB) = 1,048,576 bytes (2²⁰)
- Gibibyte (GiB) = 1,073,741,824 bytes (2³⁰)
- Tebibyte (TiB) = 1,099,511,627,776 bytes (2⁴⁰)
Result: "Gigabyte" (GB) officially reserved for exactly 1 billion bytes (10⁹)
2008: ISO/IEC 80000 standard reinforces binary prefixes:
- International standard formally distinguishes GB (decimal) from GiB (binary)
Current adoption status:
- Storage manufacturers: Universally use GB (decimal)
- Operating systems: Mixed—Linux increasingly uses GiB, Windows still shows "GB" but calculates in GiB, macOS uses GB (decimal) since 10.6
- RAM specifications: Technically should use GiB, but often marketed as "GB" (e.g., "16 GB RAM" actually means 16 GiB)
Modern Era (2000s-Present)
Gigabytes become consumer standard:
2000s: Hard drives reach 100-500 GB:
- 2000: Typical drive 20-40 GB ($5-$10 per GB)
- 2005: Typical drive 160-250 GB ($0.50-$1 per GB)
- 2008: First consumer 1 TB drive (1,000 GB) from Hitachi
- Prices consistently drop following Moore's Law-like trends
2007: iPhone launched with 4-8 GB storage:
- Made gigabytes the standard for mobile devices
- Rapidly increased to 16-32-64 GB models
2010s: SSDs mainstream (128-512 GB typical):
- Solid-state drives offer speed advantages
- Initially expensive ($1-$2 per GB in 2010)
- By 2020: $0.10-$0.15 per GB for consumer SSDs
2020s: Terabytes become consumer standard, gigabytes for mobile:
- Typical laptop SSD: 256-512 GB (budget) to 1-2 TB (high-end)
- Typical desktop HDD: 1-4 TB
- Smartphones: 64-256 GB standard, flagships 512 GB-1 TB
- Cloud storage: 15 GB free (Google), 2 GB free (Dropbox), 5 GB free (iCloud)
The "Exa-" Prefix Origins (1975)
International standardization for extreme scales:
1975: 15th General Conference on Weights and Measures (CGPM):
- Officially adopted "exa-" as the SI prefix for one quintillion (10¹⁸)
- Derived from Greek "ἕξ" (hex) meaning "six" (representing 10¹⁸)
- Part of the expanded SI prefix system: peta (10¹⁵), exa (10¹⁸), zetta (10²¹), yotta (10²⁴)
Scientific context before computing:
- Originally used in physics for extremely large measurements
- Theoretical unit until digital data made it practical
Computing Era: EB Becomes Reality (1990s-2000s)
When exabytes became measurable:
1990s: Internet and digital libraries:
- World Wide Web growth created measurable data at EB scale
- First large digital libraries reached petabyte scale
- Scientific computing began generating EB-sized datasets
2000s: Cloud computing and big data:
- 2006: Amazon S3 launch marked practical EB-scale storage
- 2008: Google File System papers discussed EB-scale systems
- 2010s: Social media, streaming, IoT accelerated data growth
2010s: Hyperscale data centers:
- 2012: Facebook data center design for EB-scale storage
- 2015: Microsoft announces EB-scale cloud capacity
- 2020s: Major cloud providers operate at multi-EB scale
EB vs. EiB: The Massive Scale Ambiguity
Confusion at the highest scales:
The root problem: Even at exabyte scale, decimal vs. binary matters
2010s: Technical vs. consumer usage:
- Cloud providers: Use EB (decimal) for marketing and statistics
- Scientific computing: Use EiB (binary) for technical specifications
- Network engineering: Mix both depending on context
Current adoption:
- Consumer/global stats: EB (decimal) dominates
- Technical specifications: EiB (binary) for precision
- Hybrid usage: Context determines which is appropriate
Common Uses and Applications: gigabytes vs exabytes
Explore the typical applications for both Gigabyte (imperial/US) and Exabyte (imperial/US) to understand their common contexts.
Common Uses for gigabytes
Storage Device Capacity
Capacity of hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, and memory cards.
Why gigabytes are the standard unit:
- Right size scale: Most consumer storage devices are 64 GB to 2 TB (2,000 GB)
- Marketing clarity: Easy to compare (256 GB vs. 512 GB vs. 1 TB)
- Universal understanding: Consumers understand "more GB = more storage"
Labeling conventions:
- Under 1,000 GB: Listed in gigabytes (128 GB, 256 GB, 512 GB)
- 1,000 GB and above: Listed in terabytes (1 TB, 2 TB, 4 TB)
- Decimal standard: All manufacturers use GB = 1 billion bytes exactly
Shopping considerations:
- Operating system overhead: Formatted capacity slightly less than advertised (file system metadata)
- Windows calculation: Shows capacity in GiB but labels as "GB" (appears 7% smaller)
- Price per GB: Compare costs (e.g., 512 GB SSD at $50 = $0.098/GB vs. 1 TB SSD at $80 = $0.080/GB)
Large File Sizes
Size of large files like high-definition movies, software applications, operating systems, and game installations.
Digital media distribution:
- Streaming services: Netflix, Disney+, Amazon Prime download options (2-10 GB per HD movie)
- Game digital distribution: Steam, Epic Games Store, PlayStation Store, Xbox Store (20-150 GB per game)
- Software downloads: Adobe Creative Cloud, Microsoft Office, professional apps (1-5 GB each)
File management implications:
- Download time: 50 GB game at 100 Mbps = ~67 minutes (12.5 MB/s × 4,096 seconds)
- Storage planning: Must ensure sufficient free space for installations
- Backup considerations: Large files require external drives or cloud backup plans
RAM Capacity Specifications
Measuring Random Access Memory (RAM) capacity (though gibibyte, GiB, is technically more precise and often used by OS reporting).
RAM specifications:
- Marketing: Advertised as "GB" (e.g., "16 GB DDR4 RAM")
- Technical reality: Actually measured in GiB (16 GiB = 17.18 GB)
- Module sizes: Always binary powers (4 GB, 8 GB, 16 GB, 32 GB per module)
Why binary matters for RAM:
- Memory addressing: CPUs use binary addresses (2ⁿ)
- Physical chips: Organized in binary capacities (512 Mbit, 1 Gbit, 2 Gbit chips)
- Standard modules: 8 GB module = 8 × 1,073,741,824 bytes = 8 GiB (not 8 × 1 billion bytes)
Operating system reporting:
- Windows: Shows RAM in "GB" but calculates in GiB (16,384 MB = 16 GiB shown as "16.0 GB")
- macOS: Shows RAM in GB (decimal) since OS X 10.6
- Linux: Increasingly uses GiB notation properly
Mobile Data Plans
Quantifying data usage in mobile data plans or internet bandwidth caps.
Plan structures:
- Prepaid plans: 5 GB, 10 GB, 20 GB, 40 GB monthly allotments
- Postpaid plans: Tiered (3 GB/10 GB/30 GB) or unlimited (throttled after 50-75 GB)
- Shared family plans: 20-100 GB shared across multiple lines
- Overage charges: $10-$15 per additional GB (or throttled to 128 kbps)
Tracking usage:
- Carrier apps: Real-time GB usage monitoring
- Phone settings: Built-in data usage trackers (iOS Settings → Cellular, Android Settings → Network & Internet)
- Warnings: Notifications at 75%, 90%, 100% of plan limit
International roaming:
- Expensive GB rates: $5-$20 per GB in some regions
- Roaming passes: Daily unlimited (e.g., T-Mobile $5/day, AT&T $10/day)
Cloud Storage and Backup
Cloud storage service allocations and usage.
Consumer backup workflows:
- Photo backup: Google Photos (unlimited compressed or 15 GB high-quality), iCloud Photos (5 GB free tier)
- Document sync: Dropbox, OneDrive, Google Drive for cross-device access
- Full system backup: Time Machine to external drive, Windows Backup, cloud backup services (Backblaze unlimited for $70/year)
Business cloud storage:
- Google Workspace: 30 GB per user (Business Starter), 2 TB per user (Business Standard)
- Microsoft 365 Business: 1 TB OneDrive per user
- Dropbox Business: 5 TB minimum (3+ users)
Bandwidth considerations:
- Initial upload: 500 GB to cloud at 10 Mbps upload = ~5 days continuous

Additional Unit Information
About Gigabyte (GB)
How many bytes are in a gigabyte (GB)?
There are exactly 1,000,000,000 (one billion or 10⁹) bytes in 1 gigabyte (GB). This is the official SI definition adopted by the International Electrotechnical Commission (IEC) in 1998. Storage manufacturers use this decimal definition universally, which is why a "500 GB" hard drive contains exactly 500 billion bytes.
How many megabytes (MB) are in a gigabyte (GB)?
There are 1,000 megabytes (MB) in 1 gigabyte (GB), following the SI decimal standard. To convert GB to MB, multiply by 1,000. To convert MB to GB, divide by 1,000. For example: 5 GB = 5,000 MB, and 2,500 MB = 2.5 GB.
What is the difference between a gigabyte (GB) and a gibibyte (GiB)?
A gigabyte (GB) uses the decimal prefix 'giga-' and equals 10⁹ (1,000,000,000) bytes. A gibibyte (GiB) uses the binary prefix 'gibi-' and equals 2³⁰ (1,073,741,824) bytes. A gibibyte is approximately 7.37% larger than a gigabyte (1 GiB ≈ 1.074 GB). Storage manufacturers use GB (decimal), while Windows calculates storage in GiB but mislabels it as "GB," creating the infamous "missing storage" confusion where a 500 GB drive shows as 465 GB (actually 465 GiB) in Windows.
What is the difference between a gigabyte (GB) and a gigabit (Gb)?
A gigabyte (GB) measures data storage capacity in bytes, while a gigabit (Gb) measures data in bits, commonly used for data transfer rates (e.g., Gbps). Since 1 byte = 8 bits, 1 gigabyte (GB) = 8 gigabits (Gb). File sizes are measured in GB, while internet connection speeds are measured in Gbps. A 1 Gbps connection downloads at approximately 125 MB/s (megabytes per second) or 0.125 GB/s—NOT 1 GB/s!
How much storage is 1 GB?
1 GB can store approximately:
- 200-300 smartphone photos (3-5 MB each)
- 250 MP3 songs (4-minute songs at 128 kbps)
- 1,000 text documents (Word files with some images)
- 40-60 minutes of 1080p video (compressed)
- 12-15 minutes of 4K video (compressed)
- 500,000 plain text files (2 KB each)
For reference, a typical 1080p movie is 4-5 GB, a modern smartphone photo is 3-5 MB (so 1 GB holds about 250 photos), and a large PC game is 50-150 GB.
Why does my 500 GB hard drive show as 465 GB?
This is the infamous "missing storage" phenomenon caused by two different unit systems:
What's happening:
- Manufacturer's claim: 500 GB = 500,000,000,000 bytes (decimal, using 10⁹)
- Windows calculation: Divides by 1,073,741,824 (binary GiB, using 2³⁰) = 465.66 GiB
- Windows display: Shows "465 GB" (but actually means 465 GiB, mislabeled)
You didn't lose 35 GB—it's just unit conversion. Your drive contains exactly 500 billion bytes as advertised. The 7.37% difference is because gibibytes (used by Windows) are larger than gigabytes (used by manufacturers). Additionally, ~1-2% is used for file system overhead after formatting.
macOS handles this better: Since OS X 10.6 (2009), macOS displays storage in decimal GB matching manufacturers, so a 500 GB drive correctly shows as "500 GB."
How long does it take to download 1 GB?
Download time depends on your internet connection speed:
Common internet speeds:
- 10 Mbps: 1 GB = ~13 minutes (1.25 MB/s)
- 50 Mbps: 1 GB = ~2.7 minutes (6.25 MB/s)
- 100 Mbps: 1 GB = ~80 seconds (12.5 MB/s)
- 1 Gbps (gigabit fiber): 1 GB = ~8 seconds (125 MB/s)
Calculation: Divide Mbps by 8 to get MB/s (because 1 byte = 8 bits), then divide 1,000 MB (1 GB) by MB/s to get seconds.
Real-world note: Actual speeds are typically 70-90% of advertised due to network overhead, server limitations, and congestion.
How much does 1 GB of storage cost?
Storage costs have dropped dramatically over decades:
Historical costs per GB:
- 1985 (IBM 3380): ~$40,000-$50,000 per GB
- 1991 (IBM Corsair): ~$2,665 per GB
- 2000: ~$5-$10 per GB (consumer HDDs)
- 2010: ~$0.10-$0.20 per GB (HDDs), $1-$2 per GB (SSDs)
- 2020: ~$0.02-$0.03 per GB (HDDs), $0.10-$0.15 per GB (SSDs)
- 2024: ~$0.015-$0.02 per GB (HDDs), $0.06-$0.10 per GB (SSDs)
Modern examples (2024):
- 1 TB HDD: $40-$50 → $0.04-$0.05 per GB
- 1 TB SSD: $70-$90 → $0.07-$0.09 per GB
- Cloud storage (Google One 100 GB): $1.99/month = $23.88/year → $0.24 per GB per year
Storage costs continue declining ~30-40% annually for SSDs, more slowly (~10-20%) for HDDs.
Is 128 GB enough storage?
128 GB is the minimum usable storage for modern devices, but adequacy depends on usage:
Sufficient for:
- Chromebooks/lightweight laptops: Web-based work, streaming (not downloading) media
- Budget smartphones: Light app users, cloud photo storage enabled
- Tablet for consumption: Reading, streaming, casual gaming
Inadequate for:
- Gaming PCs: Modern games are 50-150 GB each—only 1-2 games fit
- Content creators: Video editing, photography (RAW files), graphic design
- Heavy app users: Many large apps, offline media libraries
- Professional work: Large software suites (Adobe, CAD, development environments)
Recommendation: 256 GB minimum for comfortable general use, 512 GB-1 TB for gaming/content creation, 2 TB+ for professional media work.
How many gigabytes per month for internet usage?
Average household internet usage varies widely:
Light users (10-50 GB/month):
- Email and web browsing
- Occasional video streaming (few hours/week)
- Social media browsing
- Online shopping
Moderate users (50-250 GB/month):
- Regular HD video streaming (1-3 hours/day)
- Video calls and remote work
- Music streaming
- Software/app downloads
Heavy users (250-500 GB/month):

About Exabyte (EB)
How many bytes are in an exabyte (EB)?
There are exactly 1,000,000,000,000,000,000 bytes (one quintillion bytes, or 10¹⁸ bytes) in 1 exabyte (EB). This is the official SI definition. For perspective, this is enough storage to hold:
- All books ever written: ~500,000 times over
- Every photo ever taken: ~50,000 times over
- 50,000 years of continuous HD video recording
- The complete DNA sequence of every human on Earth: ~7.5 million times over
How many petabytes are in an exabyte?
There are exactly 1,000 petabytes (PB) in 1 exabyte (EB). This follows the SI decimal standard where each prefix increases by 1,000. Therefore:
- 1 EB = 1,000 PB
- 1 PB = 1,000 TB
- 1 TB = 1,000 GB
- So 1 EB = 1,000 × 1,000 × 1,000 GB = 1,000,000,000 GB
How many terabytes are in an exabyte?
There are 1,000,000 terabytes (TB) in 1 exabyte (EB). Using the conversion:
- 1 EB = 1,000 PB
- 1 PB = 1,000 TB
- Therefore: 1 EB = 1,000 × 1,000 TB = 1,000,000 TB
This means 1 EB could theoretically store the entire iTunes music library (50 million songs) approximately 20,000 times, or store 1 million typical PC hard drives worth of data.
What is the difference between EB and EiB?
EB (exabyte) equals exactly 1,000,000,000,000,000,000 bytes (10¹⁸) using the SI decimal prefix system. EiB (exbibyte) equals exactly 1,152,921,504,606,846,976 bytes (2⁶⁰) using the IEC binary prefix system. An exbibyte is approximately 15.3% larger than an exabyte (1 EiB ≈ 1.153 EB).
This distinction matters at exabyte scale:
- Cloud storage providers advertise in EB (decimal)
- Technical specifications may use EiB (binary)
- 100 EB of cloud storage = 86.7 EiB of actual binary capacity
How much data is created globally each year?
Global annual data creation reached approximately 120 exabytes (EB) in 2023, according to various industry estimates. This includes:
- Video content: 80 EB (streaming, social media, surveillance)
- Photos and images: 20 EB (smartphones, social media, professional)
- Text and documents: 10 EB (emails, web content, documents)
- IoT and sensors: 25 EB (connected devices, industrial sensors)
- Scientific data: 15 EB (research, astronomy, genomics)
By 2030, annual data creation is projected to reach 500 EB globally.
How much storage do major cloud providers have?
Major cloud providers operate at exabyte scale:
Amazon Web Services (AWS):
- Total storage capacity: 100+ EB
- S3 object storage: 200+ EB of customer data
- Additional services: 50+ EB across other storage types
