| Download 1 TB | $10.00 |
A TB is 1012 bytes. 1 TB stored for a month is $2.50. Uploading it is $1.00. Downloading it is $10.00. 50 TB stored for a month is $125. Uploading 50 TB is $50. Downloading 1 TB of that archive is $10.00.
How storage is measured
You are billed for your own data, not the network expansion behind it.
Tessera stores 30 shards across 30 providers so any 10 rebuild the file. That redundancy is real cost. It is Tessera’s cost to the hosts, already in the rate. You are billed for logical volume: whole 40 MiB blocks of your own data.
What tessera usage shows
| Row | Meaning | One 1.70 MiB PDF on its own |
|---|---|---|
| logical size | your files' own bytes | 1.70 MiB |
| stored | whole 40 MiB blocks; storage is billed on this column | 40 MiB (1 block) |
| network size | stored × 3: each block becomes 30 pieces of 4 MiB on 30 hosts, any 10 rebuild it; Tessera pays the hosts for this, already in the rate | 120 MiB |
A block is billed whole, so a single small file still fills one. Uploading a folder, or tessera sync, packs small files into shared blocks. Uploading many small files together is cheaper than uploading them one at a time.
Downloads are measured from host spend within about 15 minutes, and billed in 40 MiB blocks at the live download rate. The account shows egress_billed_blocks and egress_used_bytes (blocks × 40 MiB): the byte count is what you paid for, not the exact bytes the client read. The technical-validation download is separate and is not billed.
Days left is an estimate: balance divided by today’s storage charge for what you store now. More uploads or downloads shorten it. It is not a promise.
