What 100 GB gets you
At 100 GB the pick is Dropbox at $11.99 for 2 TB — far more capacity than needed, but cheaper than the plans that match 100 GB exactly.
That mismatch is the normal state of cloud pricing: plans are sold in large steps, so the smallest paid tier is usually several times the storage you asked for.
How the comparison works
The page filters plans that cover the storage you need and ranks them by monthly price. Capacity above the requirement is not a benefit unless you will use it, so the cheapest plan that fits is usually the right answer.
Worked example: 100 GB
Free tiers (2–15 GB) do not cover 100 GB.
Entry paid tiers start around 100 GB and run to 2 TB.
Dropbox at $11.99 for 2 TB is the lowest monthly price among the plans that fit.
Per GB that is about $0.006 — but per GB is the wrong metric when 1.9 TB goes unused.
What actually decides the choice
- Sharing and collaboration. If others must edit files, the plan’s sharing model matters more than capacity.
- Device sync. Some services count every synced device; others charge per seat.
- Photos. Unlimited photo storage on some plans can make a smaller quota irrelevant.
- Egress and restore. Large downloads or a full account restore can be limited or billed.
- Annual billing. Most of these prices assume a yearly commitment; monthly billing is typically 20–30% more.
Where the price can be beaten
For 100 GB of static backup, object storage such as S3-compatible services can cost a few dollars a month — but you manage the client, and retrieval is billed. For a family sharing documents, a bundled office suite with 1 TB is often better value than the cheapest pure storage plan.
What to check before subscribing
Confirm the plan’s actual storage, whether the price is per user or per account, and what happens at renewal — introductory rates commonly rise in year two.
Frequently Asked Questions
Why does 100 GB need a 2 TB plan?
Because providers sell plans in large steps. There is often no 100 GB paid tier, so the cheapest plan that covers 100 GB also includes far more space than you asked for.
Is the price per month or per year?
The comparison uses monthly-equivalent pricing, which for most providers assumes annual billing. Paying monthly is typically 20–30% more.
What about free tiers?
Free plans generally offer 2–15 GB, which does not cover 100 GB. They are useful for testing a service, not for storing a photo library.
Is cheaper object storage a real alternative?
For backup of static files, yes — a few dollars a month plus retrieval costs. It is not a drop-in replacement for a synced folder, because you supply the client and manage versions yourself.
Do prices renew at the same rate?
Often not. Introductory rates for the first year are common, and renewal can be 30–50% higher. Check the renewal price before committing to an annual plan.
