Non-volatile storage is a cornerstone of modern computer systems. Every modern photo, email, bank balance, medical record, and other critical pieces of data are kept on digital storage devices, often replicated many times over for added durability.
Non-volatile storage, or colloquially just "disk", can store binary data even when the computer it is attached to is powered off. Computers have other forms of volatile storage such as CPU registers, CPU cache, and random-access memory, all of which are faster but require continuous power to function.
Here, we're going to cover the history, functionality, and performance of non-volatile storage devices over the history of computing, all using fun and interactive visual elements. This blog is written in celebration of our latest product release: PlanetScale Metal. Metal uses locally attached NVMe drives to run your cloud database, as opposed to the slower and less consistent network-attached storage used by most cloud database providers. This results in a blazing fast queries, low latency, and unlimited IOPS. Check out the docs to learn more.
Très bel article avec pas mal d'éléments interactifs sur l'évolution des technologies de stockage : des bandes magnétiques aux SSD modernes et leurs impacts sur la latence des I/Os.

From Wikipedia:
Disk partitioning or disk slicing is the creation of one or more regions on secondary storage, so that each region can be managed separately.
An entire disk may be allocated to a single partition, or multiple ones for cases such as dual-booting, maintaining a swap partition, or to logically separate data such as audio and video files. The partitioning scheme is stored in a partition table such as Master Boot Record (MBR) or GUID Partition Table (GPT).
