Volume Storage (Block Storage)
Volume storage (also known as block storage) is manually created by the user. Upon creation, Its size can be determined by the user. You can use a volume as an external hard drive and it's to attach it to an instance. Please note that it can only be attached to a single instance at a time, although you can detach and reattach it to different instances.
Because every application and every platform is unique, we offer three different tiers so you can choose a storage solution that suits your needs. Our Low tier is the best solution for large amounts of data that do not require high I/O performance, such as backups. Our Regular tier uses HDD storage and can be used for most applications that do not require the highest performance possible. In case you are looking for the best, and fastest storage solution on the market, please select our High tier. It's extremely fast because of state-of-the-art SSD technology.
If you take a snapshot of a volume or an instance based on a bootable volume, this snapshot is stored on the same storage you use for the volume. The size of the snapshot is equal to the size of the allocated space of the volume you make a snapshot of.
