40 Storage Terms

Archive
A packaged collection of files, often compressed and stored in a format such as zip, tar, or tar.gz for transfer, backup, or distribution. Archives are also...
Binary Data
Data represented in raw byte form rather than as plain human-readable text, such as images, audio, serialized objects, compiled artifacts, or protocol...
Bit Bucket
A joking term for a place where discarded data, failed output, or ignored results supposedly go. The phrase comes from older computing humor and survives as a...
Bit Bucket Slang
A casual reference to the imaginary place where discarded bits, failed output, or ignored data supposedly go. In old-school computing slang, the bit bucket is...
Blob
Short for binary large object, a chunk of opaque data stored as a single value, often in databases, object storage, or browser APIs. Blobs are used for things...
Block Device
A storage device interface that reads and writes fixed-size blocks of data, such as a disk, SSD, or virtual volume. Block devices sit below filesystems and are...
Block Storage
A storage type that splits data into fixed-size blocks and stores them with unique addresses, mimicking a physical hard drive. Provides low-latency random...
Boot Sector
A casual reference to the disk sector involved in startup logic, often used loosely in conversations about low-level boot problems. In old-school systems...
Bucket
A grouping container used to hold related items, often in hash tables, cloud object storage, or rate-limiting logic. The exact meaning depends on context, but...
Cloud Storage
Data storage provided by a cloud platform, including object, block, and file storage services that can scale independently of local hardware. Cloud storage...
Container Volume
A storage mount attached to a container so data can persist beyond the container's writable layer or be shared with other containers and processes. Volumes are...
Credential Store
A system, file, vault, or protected location used to store passwords, tokens, keys, or other authentication material. The quality of the credential store...
Database
An organized collection of structured data managed by a database management system (DBMS). Relational databases (PostgreSQL, MySQL) use tables with SQL. NoSQL...
data lake
A centralized storage repository that holds vast amounts of raw data in its native format — structured, semi-structured, and unstructured — until it is needed...
data warehouse
A central repository of structured, cleaned, and organized data optimized for analytical queries and reporting. Unlike operational databases designed for fast...
Disk Forensics
The forensic examination of storage media and file systems to recover artifacts, timelines, deleted files, and evidence of system activity. Disk forensics...
Encryption at Rest
Encryption at Rest is cryptographic protection applied to stored data so physical or offline access does not reveal plaintext. Security teams use it to enforce...
File Carving
A forensic technique for recovering files or file fragments from raw storage by recognizing known headers, footers, and structural patterns even when...
Filesystem Security
The protection of files, directories, metadata, and mount behavior through permissions, ownership, encryption, auditing, and safe configuration. Filesystem...
floppy disk
A removable magnetic storage medium enclosed in a flexible (8" and 5.25") or rigid (3.5") plastic shell. Despite holding a maximum of 1.44 MB in its final...
IndexedDB
A low-level browser API for storing large amounts of structured data on the client side, including files and blobs. Unlike localStorage (which only stores...
IPFS
The InterPlanetary File System, a distributed system for content-addressed storage and retrieval. In open-source culture, IPFS is associated with decentralized...
Local Storage
A browser API for storing key-value string data (up to ~5-10MB) that persists across sessions. Synchronous and blocks the main thread, so avoid storing large...
Log Retention
The policy and practice of keeping logs for a defined period to support investigations, compliance, operational review, or legal obligations. Too little...
Longhorn
A cloud-native distributed block-storage system for Kubernetes workloads.
Megabyte
A unit of digital size commonly used to describe file sizes, memory, or transfer amounts, usually meaning about one million bytes in everyday usage. Engineers...
Memory Bank
A store of information used by an AI system to retain and retrieve prior context, facts, or learned artifacts outside the immediate prompt window. Memory banks...
Minio Operator
The Kubernetes operator used to deploy and manage MinIO object-storage clusters in a cloud-native way.
Nextcloud
A self-hosted collaboration platform for files, sharing, calendars, and related productivity features.
NVMe
Non-Volatile Memory Express — a storage protocol designed specifically for SSDs, replacing the SATA/AHCI protocols that were designed for spinning hard drives....
Object Storage
A storage architecture that manages data as discrete objects (each with data, metadata, and a unique ID) rather than as files in a hierarchy or blocks on a...
Password Salt
A unique random value added to a password before hashing so identical passwords do not produce identical stored hashes and precomputed cracking tables become...
Persistence
The characteristic of data that survives beyond the lifetime of the process that created it, typically by being written to durable storage such as a database,...
PV
PersistentVolume — a Kubernetes storage resource provisioned by an administrator or dynamically by a StorageClass that exists independently of any individual...
Rclone
A command-line tool for syncing, copying, and managing files across local and cloud storage backends.
Rook

Volume
A persistent storage unit managed by a container runtime (such as Docker or Kubernetes) that exists independently of any single container's lifecycle, allowing...
Volume Mount
The act of attaching a volume or host directory to a specific path inside a container, making external storage accessible to the containerized application as...
