Key Features
Bytes per sector The number of bytes contained in each storage sector of a device, indicating the smallest unit of data that can be read or written by the medium.	4096
Cache The amount of internal memory reserved for a storage device’s cache, expressed in units such as megabytes (MB) or gigabytes (GB). This value indicates how much data the drive can temporarily hold to accelerate read/write operations.	64 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
Component for Specifies the type of device or system that the product is intended to be used with, such as a PC, server, notebook, surveillance system, or other electronic equipment. The value represents a single category and can be used to filter or group products by their target platform.	Server/workstation
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
Form factor Specifies the physical configuration or design of a product, such as ATX, Micro‑ATX, Mini‑ITX, tower, case with cover, etc. It describes how the device is built and what mounting or expansion options it supports.	3.5"
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 number of heads The total count of read/write head assemblies present in a hard disk drive (HDD). Each head is responsible for accessing data on one platter surface; the number of heads determines how many platters can be serviced simultaneously and influences the drive’s capacity and performance. The value is an integer without any unit.	6
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.	180 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.	20.2 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
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
Power consumption (off)	0.5 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
RoHS compliance Indicates whether the product is manufactured in accordance with the RoHS (Restriction of Hazardous Substances) directive, which limits the use of certain hazardous materials in electrical and electronic equipment.	Yes
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
Type The general category or style of the product, such as laptop, printer cartridge, or cooling fan. It helps buyers quickly identify the nature of the item and compare similar products.	HDD
