The total amount of internal flash storage available in a device, expressed as a digital capacity such as megabytes (MB) or gigabytes (GB). This attribute indicates how much data can be stored on the device’s non‑volatile memory for operating systems, applications, and user files.

The Harmonized System (HS) code is a standardized numerical identifier used internationally to classify traded goods. It consists of up to six digits, where each pair of digits represents progressively more specific product categories. The HS code facilitates customs duties, trade statistics, and regulatory compliance by providing a common language for describing products across borders.

The intended use or application of a hard drive, such as "Desktop", "NAS", "Enterprise" or "Surveillance". This attribute helps customers quickly identify the appropriate type of storage for their needs.

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.
