APTrust — $20,000/yr + $420/TB/yr (first 10 TB included)

Academic Preservation Trust charges annual membership dues of $20,000, with the first 10 TB of preserved content per member included. Additional capacity is priced at $420 per TB per year ($0.41016/GB/year). APTrust is one of the five Replicating Nodes that survived the 2018 Digital Preservation Network dissolution (E-0054) and continues to operate as a free-standing preservation service.

For C-0030: APTrust illustrates a hybrid pricing structure — flat membership floor with proportional storage overage — that sits between the fully proportional pattern of CLOCKSS / LOCKSS / HathiTrust and the flat-fee pattern of the dissolved DPN. APTrust's continued operation after DPN's dissolution shows that the node-level economics work; the consortium-level integrity contract DPN was selling on top of those nodes is what failed (E-0054), not the node services themselves.
