| Overall Provisioned Volume Size | 20 TiB |
Limits
The following table shows which limits are enforced on Block Storage usage. It also highlights some of the characteristics of the product:
| Usage | Limit |
|---|---|
| Maximum number of volumes attached to an instance | 5 |
| Maximum number of snapshot per volume | 20 |
| Maximum volume size | 10 TiB |
| Minimum volume size | 1 GiB |
| Maximum read IOPS per volume | 5K |
| Maximum write IOPS per volume | 5K |
| Maximum bandwidth per volume | 200 MiB/s |
| Minimum instance size to attach a volume | Small |
| Supported service offerings | All |
| Block storage durability on snapshot guarantee | Full durability of data only when the volume is snapshotted |
Note
As block storage volumes expose a block size of 4KiB, some software that incorrectly assume a smaller block size might not work. This issue can be circumvented by using a compatibility layer in your instance like dm-ebs on linux.
Availability
Block Storage is available in all zones.
