How Much Does 100 TB of Cloud Storage Cost?

The cost of 100 TB of cloud storage usually ranges from $500 to $2,500 per month, depending on the provider and features. Budget-friendly options like Wasabi or Backblaze charge around $500–$600 per month, while enterprise providers such as AWS, Google Cloud, or Azure can cost $2,000–$2,500 per month.

As for Athena by WebWorks Co., their pricing page currently lists plans such as Athena Helios for ₹3,999 (for 15 GB of storage) and Athena Chronos for ₹7,999 (for 30 GB) .Extrapolating that to 100 TB would be extremely expensive under their retail pricing—so for such large volumes they likely use custom enterprise pricing not publicly posted.

Storing 100 TB of data isn’t about keeping vacation photos safe. It’s about ensuring business continuity, supporting massive workflows, and having reliable backup systems in place. But how much does it actually cost?

Why Would Someone Need 100 TB of Cloud Storage?

100 TB sounds huge at first, but for many organizations it’s not excessive—it’s a requirement. Let’s look at who really needs this much space:

Media & Entertainment Companies

• Film studios, production houses, and ad agencies often shoot in 4K, 6K, or 8K quality. One hour of raw 8K footage can take up 7–8 TB. Multiply that across several projects, add editing versions and final copies, and you quickly cross 100 TB.

Healthcare Sector

• Hospitals store medical imaging such as MRIs, CT scans, and X-rays. Each file is large, and because patient histories must be retained for years, storage piles up. A medium-sized hospital can easily require 100 TB or more for patient archives.

Scientific Research & Education

• Universities and labs handling genomic research, space data, or AI model training datasets need massive storage. These projects generate hundreds of terabytes that must be securely stored and shared among researchers.

Businesses with High Client Data

• Accounting firms, legal practices, or IT companies manage sensitive client files and compliance records. With multiple clients and long retention policies, reaching 100 TB over time is common.

Backup & Recovery Systems

• Many businesses follow a “3-2-1 backup rule” (three copies of data, stored on two media, with one off-site). If your main storage is 30 TB, backups can easily add up to 100 TB.

Factors That Affect the Cost of 100 TB Cloud Storage

The cost of 100 TB storage isn’t one-size-fits-all. Different factors influence what businesses end up paying each month or year:

Type of Cloud (Public vs Private)

• Public clouds often charge lower per-TB rates, but costs rise with user licenses and transfers. Private cloud storage may seem higher upfront but usually saves money for larger teams since it avoids per-user fees.

Number of Users

• Many providers charge per user. For example, 100 TB at $800/month sounds fine, but add 50 users at $5 each, and you’re paying $1,050 monthly. Unlimited user options eliminate this extra cost.

Data Transfer Costs

• Downloading or moving files often comes with fees called “egress charges.” Businesses that regularly move large datasets may face higher monthly bills than those that mainly store files.

Performance & Speed

• Fast storage with higher bandwidth costs more. A video studio needing quick upload and download speeds will pay more than an archive service storing old records.

Security & Compliance

• Extra features like encryption, role-based access, and compliance with standards (such as HIPAA or GDPR) can push prices higher. For regulated industries like healthcare or finance, these costs are non-negotiable.

Support & Reliability

• Premium customer support and guaranteed uptime may add to pricing but are critical for enterprises that can’t afford downtime.

Example: A startup archiving research data might choose a slower, cheaper option since access is rare. But a post-production studio handling video editing will pay more for high-performance storage that speeds up daily operations.

Public Cloud vs Private Cloud for 100 TB

Choosing between public and private cloud storage significantly impacts the cloud storage 100tb cost.

Public cloud

• Storage is shared across multiple users.

• Providers often charge per TB and per user.

• Extra costs may apply for data transfers, downloads, or collaboration tools.

• Works best for small teams with lighter usage.

Private cloud

• Dedicated storage environment for your organization.

• Usually allows unlimited users without extra fees.

• Offers isolated workspaces, stronger security, and predictable costs.

• Best for businesses managing sensitive or large volumes of data.

For smaller storage needs, public plans may work. But when it comes to 100 TB, private cloud usually becomes the more reliable and cost-effective option.

Pricing Models for 100 TB Plans

There are a few common ways providers structure their pricing for 100 TB storage:

Per TB per month

Example: If the provider charges $8/TB per month, then 100 TB would cost $800 monthly. This looks simple but often comes with hidden extras like per-user fees.

Flat rate packages

Some providers offer one discounted package for 100 TB. For instance, instead of $1,000 monthly, they may charge $850 for bulk purchase.

Add-on costs

These may include fees for extra users, higher bandwidth, or premium support. While base costs might seem low, the add-ons can increase the overall expense.

For example, a startup paying $10/TB per month spends $1,000 monthly. But with 50 users at $5 each, the real cost jumps to $1,250 per month.

Typical Cost Range for 100 TB

While prices vary across providers, here’s a general idea of what you can expect:

• Public cloud: Around $800 to $1,200 per month, depending on per-TB and per-user charges.

• Private cloud: Around $1,000 to $1,500 per month, but usually with unlimited users and no hidden fees.

This means the 100 TB cloud storage cost could range between $9,600 and $18,000 annually, depending on the structure and services you choose.

Benefits of Choosing the Right Provider

Despite the challenges, the right provider makes 100 TB storage simple and cost-effective.

• Transparent pricing avoids unpleasant surprises in monthly bills.

• Scalability allows you to increase storage without rebuilding from scratch.

• Collaboration improves as teams share and access files centrally.

• Security protects business-critical data with strong safeguards.

For example, a digital agency managing multiple clients’ campaigns can save thousands yearly with bulk pricing, while also keeping data organized and safe.

Wrapping Up

The 100 TB cloud storage cost depends on how you set it up. Public storage might seem affordable for light users, but it often comes with hidden expenses. For organizations dealing with large volumes of data, private cloud storage is usually the smarter choice. It ensures unlimited users, stronger security, and predictable long-term pricing.

At the end of the day, the right option is less about finding the cheapest number and more about finding the plan that keeps your data safe while controlling expenses.
