Key Features
Application A concise statement of the intended or most suitable use cases for a product, such as the type of environment (indoor or outdoor), activity (gaming, office work, media consumption) or general application category. It helps customers quickly determine whether the item fits their needs.	Portable
Built-in battery Indicates whether the product contains a battery that is permanently integrated into its design and cannot be removed or replaced by the user. A value of "Yes" means the device has such an internal battery; "No" means it does not.	No
Bus powered Indicates whether the device receives its power supply through a bus connection such as USB, eSATA, or another standard interface. A value of "Yes" means the product can be powered directly from the bus port, while "No" indicates it requires an external power source.	USB
Capacity The total amount of space or volume that a product can hold, expressed in an appropriate unit such as GB, MB, TB for digital storage or L, ml, cl for liquid capacity. This attribute helps users compare how much content a device or container can accommodate.	4194304 MB
Colours A colour is a visual attribute that describes the hue or shade of an object or surface. It can be a single dominant colour, a combination of colours, or a range such as "Black, White". The value may be expressed in common names (e.g., Black, Silver) or descriptive terms (e.g., One Colour, Assorted).	Black
Connectivity technology The network and data interface technologies supported by the product, such as Wired, Wireless, USB, Bluetooth, or combinations thereof. Each value represents a distinct technology that can be used for communication or power delivery.	Wired
Depth The linear measurement of an object from front to back or top to bottom, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the item is and can be used for fitting, compatibility, or spatial planning.	117 mm
Drive Connection A list of the physical or logical interfaces that a hard drive uses to connect with other components, such as SATA, M.2 PCIe, U.2, SAS, NVMe, USB, or other standard connections. The values are comma‑separated and represent the supported connection types for the drive.	USB 3.0
Encryption Indicates the cryptographic method or algorithm used to protect data on the device, such as AES, WEP, or other encryption ciphers. The value is a free‑text string that may include the algorithm name and bit length (e.g., "AES 256-bit"), and can be presented in any case or format by the manufacturer.	None
Ethernet LAN Indicates whether the product includes an Ethernet LAN interface for wired network connectivity, allowing data transmission over RJ‑45 or compatible cables.	No
HDD Capacity The total amount of digital storage that an internal hard drive can hold, expressed as a numeric value with an appropriate unit such as GB, MB, or TB. This attribute helps users understand how much data the device’s built‑in hard drive can store and compare storage options across products.	4000 GB
HDD size The physical width of a hard disk drive expressed in inches or centimeters. It indicates the standard size that determines which enclosures, bays, and mounting hardware are compatible with the drive.	2.5"
Height The vertical dimension of a product measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and applies to any item where height is relevant, including books, electronics, furniture and other objects.	14.8 mm
Housing material Indica el material o la combinación de materiales con los que está fabricado el componente más importante de un producto, como metal, plástico, vidrio u otros compuestos. Este atributo ayuda a comprender la durabilidad, peso y estética del artículo.	Plastic
Interface The physical or logical interface used by a device to connect with other components, such as USB, PCI Express, SATA, Ethernet, Thunderbolt, DisplayPort, or similar standards. It indicates the technology that enables data transfer and power delivery between the product and its peripherals.	USB 3.0 / USB 2.0
LED indicators A list of the functions or statuses that an LED indicator on a device can display, such as power status, activity, link, and other operational signals.	Power
Package depth The linear measurement from front to back or top to bottom of a product’s packaging, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the packaged item is and can be used for fitting, compatibility, or spatial planning.	140 mm
Package Height The vertical dimension of a product’s packaging measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and helps customers assess how tall the package will be when stored or shipped.	31 mm
Package width The horizontal measurement of a product’s packaging, expressed in a linear unit such as millimetres or inches. It indicates how wide the package is from one side to the other and helps customers assess fit for storage, shipping, or display.	103 mm
Storage capacity The total amount of data that can be stored on the device, expressed as a numeric value with an appropriate unit such as GB, MB, or TB. This attribute helps users understand how much information the product can hold and compare storage options across different devices.	4 TB
Storage type The technology or media format used for internal or external data storage, such as hard disk drives (HDD), solid‑state drives (SSD), eMMC, microSD cards, or combinations of these. It indicates the underlying storage medium that determines performance, capacity, and compatibility with a device.	HDD
Thunderbolt technology Indicates whether the product includes a Thunderbolt interface, which allows high‑speed data transfer and power delivery in a single cable.	No
USB connector The physical interface of the main USB port on a device, such as USB‑A, USB‑B, USB‑C, Micro‑USB or Mini‑USB. It indicates the shape and electrical characteristics that determine compatibility with cables, adapters and peripherals.	Micro-USB B
USB data transfer rates The highest theoretical speed at which a device can send or receive data over its USB interface, expressed in bits per second (bps) or multiples such as kbps, mbps, gbps, etc. It represents the upper bound of throughput under optimal conditions and is useful for comparing performance across devices and USB versions.	5000 Mbit/s
USB Version The specific version of the USB standard that a product supports, expressed as a generation number and optional descriptive suffix (e.g., "3.2 Gen 1" or simply "3.0"). This attribute indicates the data‑transfer capabilities and compatibility with USB devices.	2.0/3.2 Gen 1 (3.1 Gen 1)
