Need more disk than your plan includes? The Extra Storage +50 GB add-on adds disk to your VPS. Add it on the VPS order page, alongside the plan.
The extra space is sized when your server is built. On a Linux VPS the root filesystem grows to use it automatically on first boot, so there is nothing to do: you just have a bigger disk. You can add more than one block for more space (two blocks is +100 GB, and so on).
On a Windows VPS the extra space arrives as unallocated disk. Open Disk Management, right-click the system volume and choose Extend Volume to take it in. This is standard Windows behaviour.
Extra Storage adds disk only. If you also need more RAM or CPU, moving up a VPS tier is the better value, because each tier steps up disk, memory and cores together. Use Extra Storage when the plan's RAM and CPU suit you but you want more room for data.
Straight answers.
On Linux, yes. The root filesystem expands to use the extra space on first boot. On Windows the space shows as unallocated and you extend the system volume in Disk Management.
Yes. Add more than one Extra Storage block at order time; each block is +50 GB. For a much larger disk, a higher VPS tier is usually better value.
Adding storage is additive and does not erase anything. As always, keep your own backups or add our backup options for peace of mind.
