Best object storage for egress-heavy workloads
3 models · updated 2026-09-09
The verdict
Cloudflare R2 leads — All 3 models rank Cloudflare R2 the top pick.
As of 2026-09-09, Claude, Gemini and Grok collectively rank Cloudflare R2 #1 for object storage for egress-heavy workloads on ModelsAgree — unanimous among the 3 models that have answered. The models' case: Zero egress fees is its entire thesis and the single most decisive factor for egress-heavy workloads. The models' main caveat: Storage-per-GB and Class A/B operation costs are middling and it is Cloudflare-ecosystem-gravitational. The strongest alternative is Backblaze B2 — Free egress up to 3x your average monthly storage, and truly unlimited free egress through the Cloudflare/Fastly Bandwidth Alliance partnerships, plus.

Zero egress fees is its entire thesis and the single most decisive factor for egress-heavy workloads; S3-compatible API, deep integration with Cloudflare's global CDN and Workers so bytes leave from edge PoPs at no bandwidth charge, and pricing is purely storage + operations. For anyone serving large or unpredictable read traffic (media, downloads, AI datasets, static assets), it is almost unbeatable on total cost.

Claude Zero egress fees is its entire thesis and the single most decisive factor for egress-heavy workloads; S3-compatible API, deep integration with Cloudflare's global CDN and Workers so bytes leave from edge PoPs at no bandwidth charge, and pricing is purely storage + operations. For anyone serving large or unpredictable read traffic (media, downloads, AI datasets, static assets), it is almost unbeatable on total cost.
Gemini Completely eliminates egress fees unconditionally, offers standard S3 API compatibility, and integrates natively with Cloudflare's global edge network for automatic CDN caching without cross-cloud transit hops.
Grok Unconditional $0 internet egress at any volume with no fair-use cap, S3-compatible API, and native placement on Cloudflare’s global edge (Workers + CDN) so public serving, media, and multi-cloud reads stay cheapest once traffic exceeds storage; $15/TB storage plus modest Class A/B ops is the right trade for this workload class. Assumption: the typical user is serving to the internet or other clouds, not staying inside one hyperscaler.
Where it falls shortper Claude Storage-per-GB and Class A/B operation costs are middling and it is Cloudflare-ecosystem-gravitational; not ideal for write-heavy or operation-heavy workloads, and multi-region/compliance controls are thinner than the hyperscalers.
per Gemini High-frequency metadata and write operations incur relatively expensive Class A/B request fees, and it lacks mature cold-tier storage options.
per Grok Higher raw storage than B2/Wasabi and per-request fees that add up on write-heavy or tiny-object patterns; not the pick if you only archive and almost never read.

Free egress up to 3x your average monthly storage, and truly unlimited free egress through the Cloudflare/Fastly Bandwidth Alliance partnerships, plus among the lowest storage prices in the market; simple, S3-compatible, and battle-tested for backup and media serving. Excellent value when paired with a CDN.

Claude Free egress up to 3x your average monthly storage, and truly unlimited free egress through the Cloudflare/Fastly Bandwidth Alliance partnerships, plus among the lowest storage prices in the market; simple, S3-compatible, and battle-tested for backup and media serving. Excellent value when paired with a CDN.
Gemini Pairs rock-bottom base storage pricing with zero egress fees when routed through Bandwidth Alliance CDN partners (such as Cloudflare or Fastly), plus a generous free direct egress allowance of up to three times stored data volume.
Grok Lowest credible storage among mature S3-compatible services (~$6.95/TB) with free egress up to 3× stored volume and fully unmetered egress when fronted by Bandwidth Alliance partners (Cloudflare, Fastly, Bunny); for CDN-backed serving the all-in bill often undercuts R2 because storage is roughly half. Near-tie with R2 when a partner CDN is already in the path.
Where it falls shortper Claude Egress beyond the 3x cap is billed, and raw performance/consistency and enterprise features (fine-grained IAM, global multi-region) lag the majors — best as a CDN origin, not a low-latency primary store.
per Gemini Direct public egress beyond the 3x allowance incurs per-GB costs, and centralized datacenter locations necessitate a third-party CDN to achieve global low latency.
per Grok Only two regions and a hard 3× cap unless you add a partner CDN; thinner feature set and fewer compliance checkboxes than the hyperscalers.

Flat per-GB storage with no egress and no API-request fees under its policy, making costs trivially predictable for high-download workloads; S3-compatible and simple to reason about at scale.

Claude Flat per-GB storage with no egress and no API-request fees under its policy, making costs trivially predictable for high-download workloads; S3-compatible and simple to reason about at scale.
Gemini Offers zero egress fees and zero API request charges under a simple flat storage rate, providing total cost predictability for sustained read-heavy access patterns.
Grok Flat ~$7.99/TB with $0 egress and $0 API fees under a simple 1:1 fair-use rule, no request nickel-and-diming, and straightforward S3 compatibility—predictable and cheap when monthly downloads stay near stored volume.
Where it falls shortper Claude The "no egress" is a fair-use policy capped at your stored volume — download more than you store and you can be throttled or asked to upgrade; also a 90-day minimum storage charge and 1TB minimum, punishing for churny or small-object datasets.
per Gemini Bound by a strict fair-use policy where monthly egress cannot exceed total stored data volume, alongside a 90-day minimum retention billing policy that penalizes ephemeral objects.
per Grok 1 TB monthly floor plus 90-day minimum retention punish small or high-churn buckets; sustained egress well above stored capacity is explicitly out of policy.

EU-native S3-compatible store with a low base that already includes 1 TB storage + 1 TB egress, then only ~€1/$1.20 per extra TB out—among the cheapest all-in numbers for European or cost-sensitive high-volume serving without a $0-marketing asterisk.

Grok EU-native S3-compatible store with a low base that already includes 1 TB storage + 1 TB egress, then only ~€1/$1.20 per extra TB out—among the cheapest all-in numbers for European or cost-sensitive high-volume serving without a $0-marketing asterisk.
Claude S3-compatible object storage bundled with Hetzner's famously cheap, generous bandwidth; extremely strong raw value for European-hosted, egress-heavy workloads where you want predictable low bills without CDN gymnastics.
Where it falls shortper Claude Region footprint is limited (EU-centric), the product is younger and less feature-rich than R2/B2, and there's no built-in global edge — latency for distant users needs your own CDN in front.
per Grok Locations limited to DE/FI, per-account bucket/object caps, and unused included quota does not roll over; not global and not zero-egress at extreme ratios.

Purpose-built for egress-heavy media/content delivery: geo-replicated edge storage tightly fused to a very cheap, fast global CDN, with bandwidth priced far below hyperscalers. For video, images, game assets, and software distribution, its delivery cost-per-GB and edge latency are its whole reason to exist.

True $0 public egress (most regions as of 2026) at ~$7.55/TB storage, S3-compatible classes, EU data-sovereignty story, and no API/egress line items for standard serving—solid European alternative when R2/B2 residency or US CLOUD Act exposure is a problem.

Grok True $0 public egress (most regions as of 2026) at ~$7.55/TB storage, S3-compatible classes, EU data-sovereignty story, and no API/egress line items for standard serving—solid European alternative when R2/B2 residency or US CLOUD Act exposure is a problem.
Where it falls shortper Grok Weaker global edge and ecosystem than R2; APAC free-egress window is time-limited and Standard class is single-zone unless you pay for 3-AZ.

Rank history
Just missed the top 5
Claude Storj — decentralized, genuinely low egress and good durability, but its distributed model adds operational and performance unpredictability that keeps it off the top tier for typical practitioners · Amazon S3 — unmatched durability, ecosystem, and features, but its high per-GB egress pricing is precisely the wrong fit for egress-heavy workloads — the category this question penalizes most
Gemini Storj — Offers low baseline storage and egress rates across a distributed network, but variable tail latency and decentralized node reliability keep it behind dedicated object stores for performance-sensitive egress
Grok IDrive e2 — cheapest storage and 3× free egress but thinner public-serving track record and ecosystem · Filebase — free egress and strong claimed throughput at R2-like $15/TB but smaller vendor without Cloudflare’s network
