![]() Usually logical block size is equal to 512 bytes. Selected block size may affect disk performance. We recommend creating non-replicated disks in the ru-central1-a and ru-central1-b availability zones. You can't create snapshots or images from a non-replicated disk. The information they store may be temporarily unavailable or lost in the event of failure since non-replicated disks don't provide redundancy. Non-replicated disks have a number of limitations:Ī non-replicated disk's size must be a multiple of 93 GB. Non-replicated disks outperform regular network drives and can be useful when redundancy is already provided at the application level or you need to provide quick access to temporary data. Network drives are slower than local drives in terms of performance and throughput, but they assure greater VM reliability and uptime. If a physical disk hosting a network SSD or HDD fails, a VM will continue to run and quickly regain full access to data. Non-replicated disks do not provide redundancy. Standard network SSDs and HDDs provide sufficient redundancy for reliable data storage and allow for continuous read and write operations even when multiple physical disks fail at the same time. Non-replicated SSD ( network-ssd-nonreplicated): A network drive with enhanced performance that is implemented by imposing several limitations.ĭisks are not replicated on the Yandex Cloud side, but a user can make a disk replicated using placement groups.Network HDD ( network-hdd): A standard network drive.Network SSD ( network-ssd): A fast network drive.VMs in Yandex Cloud can use the following types of disks: In addition, the license IDs ( product_ids) are inherited from the source resource, which are used to calculate the disk use cost. If a disk is created from a snapshot or image, the disk information contains the ID of the source resource. This is the storage capacity that you're charged for. The size of a disk is specified during creation. ![]() ![]() ![]() For more information, see Pricing for Compute Cloud.
