Block Storage splits data in 'blocks' and saves them seperately. Each block has a unique identifier with which it can be retrieved. Block Storage is highly flexible and offers excellent performance. For your VPS, you can make use of two types of Block Storage: Fast and Big storage.
More information about attaching your Block Storage disk to a VPS with Windows Server can be found here , for a VPS using a Linux-based OS you can find more information here.
Fast vs Big Storage
Both Fast and Big Storage are a bit like adding an extra hard disk to your VPS.
| Fast Storage | Big Storage | |
| Technique | NVMe | HDD |
| Maximum size | 10TB per Fast Storage | 40 TB per Big Storage |
| Maximum disks | 10 (can be a combination of Fast and Big Storages) | 10 (can be a combination of Fast and Big Storages) |
| Off-site back-ups | Optional | Optional |
| Suitable for | Performance driven applications (e.g. databases) | Storing large amounts of data (videos, images, backups) |
Can I add Block Storage to more than one VPS?
You can add your Block Storage disk to only one VPS at the time via the control panel. If you want to make the Block Storage available for other VPS's you possess, you could for example use NFS (Network File System) to do this. One VPS can have a maximum of 10 Block Storage disks attached to it (with a total of 400TB).
Can I increase or decrease the size of a Block Storage disk after the initial order?
You can increase the disk space of your Block Storage at any time.
A Block Storage disk cannot be downgraded after its initial order however: it is stored as an image including its unused disk space. For privacy and security reasons, we have no access to the contents of the image and as such a downgrade would almost certainly lead to data loss.
