// Storj at a glance

The easiest and most honestly priced S3-compatible decentralised storage here, but its operator filed Chapter 11 in July 2026 after the Inveniam acquisition - strong product, material corporate-continuity risk.

no KYC

++ What works

  • Transparent $7/TB storage + $7/TB egress with no API/segment fees
  • Full S3 API compatibility (gateway) plus native uplink and Object Mount
  • 25 GB free 30-day trial, no credit card
  • STORJ-token payments exempt from the $5 monthly minimum
  • Long-running network (company 2014, v3 GA 2020) with 11-nines durability design

-- What to watch

  • Operating company is in Chapter 11 (filed 2026-07-26)
  • Storage price has risen (earlier $4/TB, now $7/TB)
  • $5/month minimum floor is not a usage credit
  • 50 KB minimum billable object and 30-day minimum retention
  • Hosted S3 gateway does server-side encryption, weakening E2E vs native protocol

// Sia at a glance

One of the cheapest decentralised options with real on-chain storage proofs and a free 50 GB on-ramp, but the network is small, redundancy/renewal is the renter's job (or a hosted markup), and there is no durability SLA.

no KYC provable

++ What works

  • Among the cheapest storage: hosted from ~$2/TB/mo, open market ~$1.1/TB-mo raw
  • On-chain storage proofs and host collateral make possession verifiable and punish failure
  • Client-side encryption and erasure coding; hosts only see ciphertext shards
  • Free 50 GB hosted tier; easy Sia Storage mobile/desktop app
  • S3-compatible via s3d gateway; rclone/boto3/aws-cli supported

-- What to watch

  • Small network (~2.12 PB used of 8.56 PB capacity as of 2026-07-18)
  • No durability SLA; renter must manage renewal and repair
  • ~3x erasure overhead means effective cost is ~3x the headline host price
  • 3.9% Siafund fee on every contract payout
  • USD network prices are derived and volatile (SC-denominated)
