Buyers have long assumed a gap that wide must be a loss leader or a trap. It is neither. It is a different business model built on a different cost stack.
For most of the last decade, a terabyte of hot object storage from a challenger cloud cost about the same as a sandwich. Backblaze B2 charged $5 per terabyte per month until October 2023. IONOS still advertises $4.99. The same terabyte on Amazon S3 Standard costs $23, a list price that has sat at $0.023 per GB in US East since 2016.
Buyers have long assumed a gap that wide must be a loss leader or a trap. It is neither. It is a different business model built on a different cost stack, and in 2026 that cost stack is being stress tested for the first time. Hetzner raised its object storage base price from €4.99 to €6.49 on April 1. Backblaze moved B2 pay-as-you-go from $6.00 to $6.95 on May 1. Wasabi went from $6.99 to $7.99 on July 1, citing "increased costs for storage hardware, energy, and data center operations."
This piece opens up the economics: where a $6.95 terabyte actually goes, the five design choices that make challenger pricing possible, why the $5 floor is cracking now, and what that means for anyone signing a storage contract this year.
The simplest test is whether the cheapest providers make money on storage. Most challengers are private, but Backblaze files with the SEC, so its numbers are the best public window into challenger economics.
In Q2 2026, Backblaze reported revenue of $42.7 million, with B2 Cloud Storage revenue up 34% year over year to $26.6 million. Gross margin was 63%, and adjusted gross margin, which strips out depreciation and stock compensation, was 80%. Adjusted EBITDA reached 30% of revenue, and the company raised its full-year revenue guidance to $172 million to $174 million.
A company losing money on every terabyte does not post a 63% gross margin. Backblaze still reports a GAAP net loss ($5.1 million in Q2 2026), but that loss sits below the gross profit line, in stock compensation, interest, and operating expenses. The storage itself is profitable at a price one third of S3.
The flip side matters just as much. If a challenger can earn a 63% gross margin at $6.95, a hyperscaler charging $23 for a comparable hot tier is not pricing to cost. It is pricing to what a captive customer will pay.
Map Backblaze's Q2 2026 income statement onto its list price and the cost stack becomes visible. The ratios below are company-wide (they include the Computer Backup business), so treat them as an illustration of the shape, not a precise B2 unit cost.
The line everyone worries about, the drives and servers, is roughly 16 cents of every revenue dollar. That is why the 2026 hard drive shock translated into a 16% list price increase at Backblaze rather than a 46% one. Depreciation spreads each drive purchase over years of service, so a spike in drive prices only reaches the income statement as old capacity is replaced and new capacity is added.
Half of the price covers engineering, sales, and administration. This is where scale matters most, and where a single-product company has a structural edge over a hyperscaler: there is no parallel organization building 200 other services whose overhead has to be recovered somewhere.
Hyperscaler object storage is one service inside a platform that has to fund compute, databases, networking, AI services, and a global sales force. Challengers build one storage product, one API (S3-compatible), and one billing model. Fewer features means less engineering, less support surface, and a much simpler rate card.
Backblaze published its first open-source Storage Pod design in 2009 to avoid enterprise storage array pricing, and it has kept pushing density since. Its Q1 2026 Drive Stats report shows 26TB drives now in the fleet. Every jump in drive capacity spreads the cost of chassis, rack space, power, and cooling over more terabytes, which is the single most reliable lever on cost per TB.
Amazon S3 Standard stores data redundantly across at least three Availability Zones by default. Backblaze splits each object into data and parity shards spread across 20 storage servers in a "Vault" inside one data center (17 data and 3 parity shards in its long-standing design). Parity overhead of roughly 18% is far cheaper than full cross-zone replication. The trade-off is real and discussed below: single-region storage does not survive the loss of a region unless you pay to replicate it.
Flat pricing only works if a few customers cannot turn it into a loss. Challengers protect the model with usage rules rather than line items. Wasabi bills a 1TB minimum, charges for a 90-day minimum storage duration, and keeps egress free only while monthly downloads stay at or below the volume stored. Backblaze includes free egress up to three times average monthly storage, then bills $0.01 per GB. These clauses are not fine print. They are the mechanism that keeps the headline price viable.
AWS charges $0.09 per GB for the first 10TB a month of internet egress from S3, which is $90 per terabyte moved, nearly four times the monthly cost of storing that terabyte. Challengers give most of that away because wholesale bandwidth costs a small fraction of that rate. Cloudflare R2 takes the logic furthest: it charges $0.015 per GB-month for storage, more than double Backblaze, but zero for egress, because Cloudflare already operates one of the largest networks on the internet and monetizes it elsewhere. Different model, same insight: egress fees are a lock-in tool, not a cost recovery tool.
The challenger model depends on buying drives cheaply and in volume. That assumption broke this year. On its February earnings call, Western Digital said it is "pretty much sold out for calendar 2026," with long-term agreements already signed for 2027 and 2028. Seagate said its nearline capacity is "fully allocated through calendar year 2026." Tom's Hardware reported average hard drive prices up 46% since September 2025.
| Provider | Before | After | Change |
|---|---|---|---|
| Hetzner Base price, Germany/Finland, April 1 |
€4.99 | €6.49 | +30% |
| Backblaze B2 Pay-as-you-go, May 1 |
$6.00 | $6.95 | +16% |
| Wasabi Pay-as-you-go, July 1 |
$6.99 | $7.99 | +14% |
| IONOS Listed, September 2026 |
$4.99 | $4.99 | No change |
| Amazon S3 Standard US East, first 50TB |
$23.00 | $23.00 | No change |
Those supply agreements favor the largest buyers. Western Digital told investors it holds firm purchase orders from its top seven customers. A challenger buying a fraction of that volume pays closer to spot pricing and waits longer. The hyperscalers, whose storage prices were never cost-based, have not moved their list prices. The challengers, whose prices are cost-based, have had to.
IONOS is the notable holdout. Its object storage page still lists $4.99 per TB, although data transfer is billed separately, so the all-in number depends on how much you read back. We covered its pricing strategy in depth with the IONOS team on the DataStorage.com Podcast (Ep 3).
The other response is to lock in demand so drive purchases can be planned years ahead. In Q2 2026 Backblaze signed a five-plus-year, $335 million agreement with CoreWeave, lifting its remaining performance obligations to $396 million. ARR from customers paying $50,000 or more grew 67% year over year. Backblaze CEO Gleb Budman, who discussed the company's challenge to hyperscaler pricing on our podcast (Ep 1), now frames B2 as the capacity storage layer for AI. Committed contracts give a challenger the forecast it needs to negotiate drive supply the way a hyperscaler does.
Cheap storage is cheap for identifiable reasons, and each reason has a buyer-side consequence.
Consider a media or AI team keeping 100TB of hot data and pulling 30TB a month out to users, partners, or a GPU cloud. At September 2026 list prices in US regions, excluding request fees:
| Provider | Storage | Egress | Monthly total |
|---|---|---|---|
| Amazon S3 Standard | $2,250 | $2,591 | $4,841 |
| Cloudflare R2 | $1,500 | $0 | $1,500 |
| Wasabi | $799 | $0 | $799 |
| Backblaze B2 | $695 | $0 | $695 |
The S3 bill is seven times the B2 bill, and more than half of it is egress. That ratio, more than any storage rate, explains why the GPU and storage decisions are now the same decision: every move between compute providers drags data behind it.
Challenger storage was never cheap because it was subsidized. It was cheap because it was honest about cost. In 2026, that honesty is showing up on the rate card, and the buyers who model the whole bill will still come out ahead.
