# Package: Storage Type

The storage types available on the Service Portal AI are designed to accommodate different data performance and capacity needs, ranging from general-purpose workloads to high-speed I/O operations. Each storage type offers a specific combination of speed, durability, and cost. Here’s an overview of the available options:

| **Storage type** | **Description**                                                                                                                                                                                                                                                    | **Storage class name**                                                                                                                                       | **Access Mode**                                                                    |
