The following are the storage solutions offered by Vultr.
The Vultr Object Storage solution allows you to handle large amounts of unstructured data. This storage solution is highly flexible and infinitely scalable. It divides the files you upload into where each object contains the data, metadata, and unique identifier that applications can use for access and retrieval. The price of the object storage service depends on the total storage and outbound transfer bandwidth.
The Vultr Block Storage solution allows you to create expandable volumes and mount them to your compute instances. These volumes are storage blocks that replicate a physical disk's functionality. You can also use them for persistent volumes in your Vultr Kubernetes Engine clusters. The price of the block storage volumes depends on the total storage and the storage class.
The local storage solution refers to the inbuilt storage of your compute instances. This storage is directly attached to the instance. The total capacity is propositional to the compute resources of your instance, such as the vCPUs, RAM, and so on. The more resources your instance has, the more local storage capacity you will have. The instance plan you select includes the price of the local storage.
