NAS, Backup & Storage Tech Dictionary (S-Z)


Covering Terms

For terms from N-R, visit NAS, Backup & Storage Tech Dictionary (N-R).


SaaS (Software as a Service) -

SaaS (Software as a Service) is a cloud-based software delivery model where applications are accessed via the internet, eliminating the need for local installations. It’s often integrated with NAS systems for data backup and collaboration.

Secure Boot -

Secure Boot is a security feature that ensures a device starts using trusted software only. In NAS devices, it protects against malware attacks during startup, enhancing system integrity and data security.

SFTP (Secure File Transfer Protocol) -

SFTP (Secure File Transfer Protocol) is a secure method for transferring files over a network, encrypting both data and commands. It’s commonly used in NAS environments to protect sensitive files during remote transfers.

SMB (Server Message Block) -

SMB (Server Message Block) is a network protocol that enables file and printer sharing between devices. Widely supported in NAS systems, SMB allows seamless access to shared folders across Windows, macOS, and Linux devices.

Snapshot -

A snapshot is a point-in-time copy of data, allowing quick recovery in case of accidental deletion, corruption, or ransomware attacks. In NAS systems, snapshots are vital for disaster recovery and maintaining data integrity.

SODIMM (Small Outline Dual In-Line Memory Module) -

SODIMM is a smaller, more compact version of DIMM RAM, primarily used in laptops and compact devices. Many NAS systems with user-upgradable memory slots support SODIMM modules, allowing users to boost performance without taking up too much physical space.

SSD (Solid State Drive) -

An SSD (Solid State Drive) is a high-speed storage device that uses flash memory instead of spinning disks. In NAS setups, SSDs improve performance, enabling faster data access, file transfers, and application responsiveness.

SSD Cache -

SSD cache uses an SSD to temporarily store frequently accessed data, speeding up read and write operations in NAS systems. It enhances performance without needing to replace existing hard drives entirely.

Static IP -

A static IP is a fixed, unchanging IP address assigned to a device on a network. In NAS environments, static IPs ensure consistent remote access, simplify port forwarding, and enhance network stability.

Storage Pool -

A storage pool is a collection of physical drives combined to create a flexible, scalable storage space. In NAS systems, storage pools allow for efficient data management, redundancy, and easy expansion as storage needs grow.

Subnet Mask -

A subnet mask is a numerical label that divides an IP address into network and host parts, helping devices communicate within a local network. It’s essential in NAS configurations for managing IP assignments and network segmentation.
[Back to top]


Throughput -

Throughput measures the amount of data transferred over a network within a specific time frame, usually in Mbps or Gbps. In NAS systems, higher throughput ensures faster file transfers and efficient data handling.

Two-Factor Authentication (2FA) -

Two-Factor Authentication (2FA) adds an extra layer of security by requiring a second verification method, like a code sent to your phone. In NAS environments, 2FA helps protect sensitive data from unauthorized access.

Unbuffered Memory -

Unbuffered memory is a type of RAM that does not include a memory buffer or register, making it faster but slightly less stable than registered memory under heavy workloads. Most consumer-grade NAS devices and personal computers use unbuffered memory due to its cost-effectiveness and lower latency.
[Back to top]


UPS (Uninterruptible Power Supply) -

A UPS (Uninterruptible Power Supply) provides backup power during outages, preventing data loss and hardware damage. For NAS devices, a UPS ensures safe shutdowns and protects against sudden power interruptions.
[Back to top]


VLAN (Virtual LAN) -

A VLAN (Virtual LAN) segments a physical network into multiple logical networks for better security and performance. In NAS setups, VLANs help isolate traffic, improve data security, and optimize network management.
[Back to top]


Volume -

A volume is a logical storage unit created within a NAS from one or more drives. It organizes data efficiently, supports features like RAID, and helps manage file systems and storage space effectively.
[Back to top]


VPN (Virtual Private Network) -

A VPN (Virtual Private Network) creates a secure, encrypted connection over the internet, protecting data from prying eyes. Using a VPN with NAS devices ensures safe remote access to your files from anywhere.
[Back to top]


WAN (Wide Area Network) -

A WAN (Wide Area Network) connects devices over large geographic areas, like between offices or across the internet. In NAS systems, WAN support allows for remote file access, backups, and data synchronization.
[Back to top]


WebDAV (Web Distributed Authoring and Versioning) -

WebDAV (Web Distributed Authoring and Versioning) is a protocol that allows users to manage and edit files on remote servers. It’s commonly used with NAS devices for easy remote file access and collaboration.
