Out of disk space? Add a volume in a minute
Block storage — extra disks for your servers: attached on the fly, resized without downtime and moved between instances. Your database or photo archive grows — the disk grows, not the bill for a new server.
Why a separate volume
The most common scenarios where an extra disk beats upgrading the whole server
The disk grew — the server stayed
Low on space but CPU/RAM is enough. An extra volume is available in the 0.0013 USD/day — 0.96 USD/month range — instead of upgrading the whole instance.
A dedicated disk for the database
The database on its own volume: the app's disk doesn't compete with the DB disk, and volume backups and snapshots run independently.
Data outlives the server
A volume is independent of the instance: delete the server and the data remains. Detach from one, attach to another — a move in minutes with no copying.

Block or Object?
In short: Block Storage is a disk for a server (file system, DB, OS). Object Storage is independent file storage accessible over HTTPS/S3 from anywhere (backups, media, static).
| Criterion | Block Storage | Object Storage (S3) |
|---|---|---|
| What it is | a disk attached to an instance | file storage with an API |
| Access | only from the server it's attached to | from anywhere over HTTPS/S3 |
| What for | OS, file system, databases | backups, media, archives, static |
| Price | 0.0013 USD/day — 0.96 USD/month | $0.0013/GB/mo |
Rule of thumb: hot data that needs disk speed goes here; everything you just “store and serve” goes to Object Storage.

How to connect — 3 steps
From creating a volume to a working disk in the system — in minutes
Create a volume
In the panel: choose the size and location (the same as the instance).
Attach it to the instance
The volume appears in the system as a regular disk.
Mount and use it
Partition, mount — and the disk is ready. A Linux guide is in the knowledge base.
