Since during the open beta period, ESSD cloud disk has only one storage type, if you are using ESSD cloud disks that are created before June 28, they are recognized as PL1 type and the billing rule remains unchanged. However, any ESSD cloud disk created after June 28 should refer to the latest disk types and billing rules. We recommend that you choose ESSD cloud disk types on-demand, so as to avoid unnecessary costs. For more information choosing the type of ESSD cloud disk, please see the Block storage FAQ.
