| Free tier | 5 GB free: the vendor's own manual reads 免费 5G, 黄金 50G, 白金 200G, 钻石 2048G. Membership is CNY 72, 252 and 816 a year, with promos putting 2 TB at CNY 239 to 408 unit GiB; metered on stored-bytes |
|---|---|
| Price | 2 TB at CNY 408/yr promotional is about USD 2.4/TB/month, and CNY 816/yr list about USD 4.8/TB/month |
| Limits | |
| Binding | per-object-cap The per-file ceiling is unpublished, so the account total is what binds. |
| Identity | email a Xiaomi account. Xiaomi's own FAQ says a non-mainland account 'can only be created through email', which is an open door into the region where the storage product was killed. Only a mainland account still has the 2 TB tier |
| Egress | No published cap, and the drive is deliberately not share-oriented: the community notes 不能对外分享. Third-party clients download at full speed with concurrency 20 |
| Per-object cap | Not published; the drive is sync-oriented and does not expose a single-file ceiling |
| Retention | Account ownership is not transferable; the global-region Gallery sync and all memberships were terminated on 2022-10-25 outside the mainland, with stored Gallery data deleted by mid-2023 |
| Interface | rest, cli |
| Tooling | a reverse-engineered REST interface at i.mi.com with a Go CLI, wangbjun/go-micloud, doing login, list, upload, download, share and tree at concurrency 5 up and 20 down; an unmerged OpenList driver pull request 1391 implements list, link, put and mkdir but its body says 还没写完 |
| Composes with | The API is real and a wrapper exists, so it would be the cleanest phone-vendor target. 5 GB free means about 410 accounts per 2 TB and the 2 TB tier is CNY 239 to 408 a year, which is not a stacking play |
| Reliability | Global-region Gallery sync and all memberships were terminated outside mainland China in three regional waves by 2023-02-01, with Gallery data deleted by mid-2023. An email signup works and lands in the region where the product no longer exists, which is a worse outcome than a closed gate because it looks open |
| Notes | The most interesting failure in the phone-vendor group because the gate is inverted: email registration works and it is the wrong region. |
