What is on-premises data storage?

On-premises storage means data is kept on devices the business owns at its own site. Internal hard drives, external drives and office servers are examples.

How do hard disk drives differ from solid-state drives?

A hard disk drive stores data on spinning magnetic platters and is cheaper per gigabyte. A solid-state drive uses flash memory with no moving parts, so it is faster and more robust.

What is network-attached storage (NAS)?

NAS is a storage device connected to an office network that several users can share. NAS gives central on-premises storage without a full server.

What is a data centre?

A data centre is a secure building housing large numbers of servers, storage systems and network equipment. The centre provides reliable power, cooling and physical security.

How can a business use a data centre without building its own?

A business can rent space for its own servers in a shared data centre, known as colocation. A business can also rent servers owned by the data centre operator.
