Two storage types
One instance, or many
The difference is who can mount it at the same time.
Cloud Drive
Block storage (read-write-once) attached to one GPU instance at a time. A durable home directory for a single workspace: checkpoints, notebooks, rendered frames.
Attaches to GPU instances. Default mount /workspace/data-01.
Shared Filesystem
CephFS-backed shared storage (read-write-many) mounted by many instances at once and by every replica of a GPU cluster. Put datasets and model weights here once and read them from everywhere.
Attaches to GPU instances and clusters; also read by fine-tuning and dedicated inference. Default mount /workspace/shared-01.
How it works
Create once, attach as often as you like
Storage is a resource of its own, not a property of an instance.
- 1
Create
Pick a type and a size (50–500 GB) in the region where your GPUs run.
- 2
Attach
Select it when launching an instance or cluster — or create it inline in the same form.
- 3
Work
It appears under /workspace next to the 400 GiB local scratch that every GPU gets.
- 4
Terminate
Stop the instance whenever you like. The volume stays, with everything on it.
- 5
Re-attach or export
Mount it on the next instance, or export a folder to a download link.
What you get
Built for datasets and model weights
Outlives any instance
Storage is a separate resource. Terminate a GPU instance and the volume is ready to attach to the next one.
One copy of the weights
A Shared Filesystem is the same path on every replica of a cluster, so a 60 GB model is downloaded once, not once per GPU.
Fixed sizes, predictable bill
50, 100, 200, 300, 400 or 500 GB. Each size is a flat monthly rate; see the live table below.
Lives next to the GPUs
Volumes are region-local, so reads and writes never cross a region boundary.
Export any folder
Browse the volume from the console and turn a folder into a download link that stays valid for three days.
5-day grace period
If your balance runs out, suspended storage stays readable for five days so you can get your data out.
