Seedbox Price Per TB (2026): What 11 Providers Actually Charge for Storage

Why the sticker price tells you almost nothing

Seedbox providers price in three different currencies and across disk sizes that range from 200 GB to 28 TB. That makes the advertised figure meaningless on its own. Three plans priced within a couple of dollars of each other illustrate the problem:

• GigaRapid Eco AF30 — €2.99/month. The cheapest plan we track, and by far the worst value for storage: 200 GB works out at roughly $17 per TB.
• Ultra.cc Lancer v2 — €4.95/month. Costs 65% more, but gives you 1 TB — about $5.70 per TB, a third of the price of the 'cheaper' plan.
• Ultra.cc Spirit v2 — €8.75/month. Nearly triple the entry price, yet the cheapest storage of the three at roughly $5 per TB.
• The pattern holds across the whole market: the lowest monthly bill and the lowest cost of storage are almost never the same plan.

How we calculated it

The method is deliberately simple, so you can reproduce it against any provider's pricing page.

• We take the monthly price, not the discounted annual rate — annual commitments distort comparisons and lock you in before you know whether the service suits you.
• We use the price in the currency the provider actually bills in, then normalise to US dollars at the reference rate on the day of the check (EUR 1 = USD 1.1485, GBP 1 = USD 1.3435, 1 August 2026).
• We divide by advertised storage, in terabytes.
• Every figure below was read from the provider's own live pricing page on 1 August 2026, not copied from an older review.

The cheapest storage on the market right now

Sorted by cost per terabyte per month, the picture is dominated by high-capacity HDD plans. These are the standout tiers:

The trap nobody advertises: upload quotas

Cost per terabyte only tells you what storage costs. It says nothing about how much data you are allowed to push out — and on several providers, that is the real limit. This is where the ranking changes shape depending on what you actually do.

• Metered upload: Ultra.cc, Whatbox and Seedboxes.cc all cap monthly upload while leaving downloads unlimited. Allowances scale with the plan (Ultra.cc runs 2–55 TB, Whatbox 10–40 TB on HDD tiers).
• Unlimited traffic: Feral Hosting and RapidSeedbox place no monthly cap on either direction, though both apply fair-use policies and Feral throttles during weekend peak hours.
• What this means in practice: if you seed heavily on private trackers, a plan with a generous upload allowance beats a plan with cheaper storage. If you are archiving a media library you mostly stream to yourself, the cheapest terabytes win outright.
• Check the upload column before the price column — it is the single most common reason people outgrow a seedbox within two months.

NVMe: five to ten times the price per terabyte

NVMe plans occupy a completely different price band, and the gap is much wider than most guides suggest. Ultra.cc's Blackbird is the cheapest NVMe storage we track at roughly $16.31/TB, and Whatbox's NVMe tiers sit at about $33.85/TB across the range — ten times the cost of good HDD storage.

That premium buys disk throughput, not capacity. It is worth paying when your bottleneck is genuinely I/O: heavy simultaneous seeding on many torrents, large numbers of concurrent Plex streams, or *arr stacks doing constant scanning and repacking. For storing and occasionally streaming a media library, it is money spent on a bottleneck you do not have.

• Ultra.cc Blackbird — €53.95 for 3.8 TB NVMe (~$16.31/TB): the best NVMe value in our index.
• Ultra.cc Tomcat — €17.95 for 950 GB NVMe (~$21.70/TB): the cheapest way to try NVMe.
• Whatbox NVMe tiers — €28 to €84 (~$33.85/TB at every size): priced consistently, on a 100 Gbps connection with very high upload allowances (50–175 TB).

What we would actually buy

Translating the numbers into recommendations, by what you are trying to do:

Three things to check before you pay

The per-terabyte ranking narrows the field, but these decide whether a plan works for you:

• Billing currency. Providers bill in EUR, GBP or USD. If your card is in a different currency, your bank's conversion spread quietly adds 1–3% to every invoice.
• Stock. The best-value tiers sell out routinely — Ultra.cc's cheapest plans in particular show zero availability for long stretches. A plan you cannot buy is not a deal.
• Monthly versus annual. Every price here is the monthly rate. Annual commitments cut 15–20% at most providers, but only take one after you have run the service for a month.

The bottom line

Cost per terabyte reorders the seedbox market in a way headline pricing hides. The cheapest monthly bill in our index (€2.99) buys the second-worst storage value on the market; spending €11 more per month buys twenty times the disk. For most people the answer sits in the €14–€22 band, where storage costs roughly $3–$4 per terabyte and upload allowances are large enough to be irrelevant.

Use the comparison tool to filter by the constraint that actually binds you — budget, storage, upload allowance or Plex support — and the shortlist usually comes down to two or three plans.
