How to Bytemark

Show documention menu


When you create a Cloud Server, the £10 base price includes a single SATA (SSD) disc, 25GiB in size. This is currently enough space for any of our supported operating systems.

You can attach up to eight discs in total to your Cloud Server. You can increase the size of a disc at any time, though you will have to shutdown your Cloud Server before your operating system will see the change. To remove a disc, you have to shutdown your Cloud Server first.

Frequently asked questions

What’s a GiB?

A GiB is a binary gigabyte, usually used for measuring a computer’s memory. It’s equal to 1073741824 (1024 × 1024 × 1024) bytes.

A GB is a decimal gigabyte, usually used for selling hard discs. It’s equal to 1000000000 (1000 × 1000 × 1000) bytes, but we find this measurement confusing and unhelpful and we don’t use it!

We try to stick to explicit references to each.

Can I use RAID on my discs to make them faster?

The virtual discs that come with your Cloud Server are already part of a RAID array and are therefore not subject to sudden data loss as a result of a physical disc failure. Your disc will have performance and redundancy from the outset! If you manually add RAID to your discs over and above the RAID that we already do for you, the performance of your discs may actually decrease.

Bytemark Cloud used to be called "BigV"—nothing has changed except the name! We’re hiring! Please visit to find out more.
