Dimensions / Weight
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.	512
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
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.	1000 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 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.	2
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.	3.5"
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.	210 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 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
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
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 drive buffer size The amount of temporary memory that a hard drive can hold before transferring data to the host system. Expressed as a digital capacity (e.g., kilobytes, megabytes). This attribute helps users understand how quickly a drive can process read/write operations and is useful when comparing performance across drives.	64 MB
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
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.	400 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.	101.6 mm
