ASUSTOR AS-604RD 4-Bay Network Attached Storage Enclosure with Rail Kits and Silver Finish

The frequency of the alternating current supplied to a power supply or charger, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the device, ensuring proper functionality and safety.

The range of alternating current voltage that the product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum supply voltages compatible with the device across different regions.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

Indicates whether the device includes one or more eSATA (external SATA) ports for connecting external storage devices. The value is a simple yes/no: "Yes" means at least one eSATA port is present, while "No" indicates none.

Represents the total count of Ethernet LAN (RJ‑45) interfaces available on a product. The value is an integer indicating how many physical Ethernet ports are present, regardless of speed or generation.

A list of the HDMI ports available on the product, each entry indicating the number of ports and their specific HDMI version or additional features (e.g., "2 x HDMI 2.0b", "1 x HDMI 1.4 with CEC"). This attribute helps users understand both the quantity and capabilities of the HDMI connections.

The total amount of internal memory available in a device, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates how much information the component can hold for active processes and affects multitasking performance.

The type of memory physically installed inside a device, such as DDR4 SDRAM, LPDDR3, or other RAM variants. It indicates the architecture and generation of the internal memory modules that the product uses or supports.

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.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

The electrical power rating of a power supply unit (PSU), expressed in watts (W). It indicates the maximum output power that the PSU can deliver to connected components, helping users assess compatibility and energy requirements for their system.

The processor family identifies the group or series of CPU models that share a common architecture, design, and performance characteristics. It helps users compare processors across brands and generations by indicating the underlying technology used in the chip.

A comma‑separated list that specifies the RAID configurations supported by a storage controller or device. Each entry can be a numeric level (e.g., 0, 1, 5, 10) or a special label such as JBOD. This attribute indicates which disk arrangements the system can manage.

List of physical or logical interfaces that allow a storage drive to connect with other components, such as SATA, M.2 PCIe, U.2, SAS, NVMe or other standard connections.

The physical width of a storage drive measured in inches or millimetres, typically expressed as the diagonal size of the drive’s enclosure (e.g., 2.5" or 3.5"). This measurement indicates the form factor that determines compatibility with computer bays, external enclosures, and mounting brackets.

The total count of physical slots or bays in a device that can accommodate storage drives such as hard disks or solid‑state drives. This value indicates how many separate drives the product can house, helping users assess expansion capacity and configuration options.
