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.	NAS
Average latency The typical time delay, measured in milliseconds, between a request and its response for storage devices such as hard drives or SSDs. It reflects how quickly data can be accessed from the device and is useful for comparing performance across similar products.	4.16 ms
Buffer The amount of data that a device can temporarily store in its internal memory before processing or transferring it. The value is expressed with a digital capacity unit (e.g., kilobytes, megabytes). This attribute helps understand the performance and efficiency of hardware when handling information streams.	128 MB
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
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.	147 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.	SATA III
Drive Size The physical form factor or dimension of a storage drive, expressed as a size in inches (e.g., "2.5"", "3.5""), an M.2 module designation (e.g., "M.2 2280"), or a memory card type (e.g., "SD Card", "microSDXC"). This attribute helps users determine compatibility with bays, enclosures, and devices that accept specific drive sizes.	3.5"
Drive type The classification of a storage device’s mechanical or solid‑state nature, such as Internal, External, Portable, Motorized, Manual, SSD, HDD, Blu‑ray Writer, etc. It indicates how the drive is mounted and operated within or outside a system.	Internal
Hard drive interface The physical or logical interface used by a hard drive to connect with other components, such as SATA, SAS, USB, PCI Express, or M.2. It indicates the technology that enables data transfer and power delivery between the device and its host system.	SATA/600
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 interface transfer rate The highest theoretical speed at which a hard disk drive can send or receive data over its interface, expressed in bits per second (bps) or multiples such as kbps, mbps, gbps, etc. This value represents the upper bound of throughput under optimal conditions and is useful for comparing performance across different drives and interfaces.	6 Gbit/s
HDD speed The number of revolutions per minute (RPM) at which a hard‑disk drive’s spindle turns, indicating the drive’s data access performance and endurance characteristics.	7200 RPM
HDD sustained transfer rate The average speed at which a storage device can read or write data under typical operating conditions, expressed in megabytes per second (MiB/s). This value reflects the sustained throughput that users can expect during continuous data transfers.	25.51 MiB/s
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.	26.1 mm
Interface List of physical or logical interfaces that allow communication between a hard drive and other devices, such as SATA, M.2 PCIe, U.2, SAS, NVMe, or other standard connections.	Serial ATA III
Non-operating shock The mass of a component or device measured while it is not operating, expressed in grams. This value represents the total weight that the unit can sustain during shock testing and includes any internal parts and packaging if specified.	300 G
Non-operating vibration	3 G
Operating shock	70 G
Operating voltage The electrical voltage that a device is designed to operate at, expressed in volts (V). It may represent a single nominal value or a range indicating the minimum and maximum supply voltages compatible with the product. This attribute helps users verify that their power source matches the device’s requirements.	5 / 12 V
PC Interface List of physical or logical interfaces that a personal computer can use to connect with other devices, such as SATA, USB, PCI Express, Ethernet, Thunderbolt, and DisplayPort. Each value represents an interface standard supported by the PC.	SATA
Power consumption (off)	0.6 W
Quantity Represents the count of individual units or pieces included in a product offering. It indicates how many separate items are available for purchase or use, such as the number of components in a bundle, the quantity of devices in a set, or the amount of consumables supplied. The value is an integer without any unit of measure.	1
Start-up current The electrical current drawn by a device when it first powers on, expressed in amperes (A). It represents the initial surge of current required to start the product and can help users assess power supply compatibility or identify potential overload risks.	2 A
Storage drive adapter included Indicates whether a storage‑drive adapter is supplied with the product. A value of "Yes" means an adapter is included in the package, while "No" indicates that no adapter is provided and must be purchased separately.	No
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.	Mechanical
Technology Type The underlying storage medium used by the product, such as hard disk drive (HDD), solid‑state drive (SSD), or hybrid configurations. It indicates the technology that determines performance characteristics like speed, durability and capacity.	HDD
Warranty The length of time for which the manufacturer guarantees that the product will be free from defects in materials and workmanship, typically expressed in years or months.	5 Year Manufacturer Warranty (View More Information)
Weight The mass of the product expressed in a standard unit such as grams or kilograms. It represents how heavy the item is and can be used for shipping calculations, handling instructions, or consumer information.	680 g
Width The horizontal measurement of a product, expressed in a linear unit such as millimetres or inches. It indicates how wide the item is from one side to the other and is used for sizing, fitting, and compatibility purposes.	101.8 mm
