Dimensions / Weight
Key Features
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.
Notebook
Data transfer rate
The maximum theoretical speed at which a device can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. It represents the upper bound of throughput under optimal conditions and is useful for comparing performance across devices and interfaces.
6 Gbit/s
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.
69.8 mm
ECC
Indicates whether the memory module or component supports Error‑Correcting Code (ECC) for detecting and correcting single-bit errors during operation. A value of "Yes" means ECC is enabled, allowing automatic correction of data corruption; a value of "No" indicates no ECC support.
Yes
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.
7 mm
Memory type
The classification of a device’s memory technology, such as DDR4 SDRAM, GDDR6, or MLC NAND. It indicates the underlying architecture and generation that determines performance characteristics like bandwidth, latency, and power consumption.
SLC
NAND flash type
The type of NAND flash memory cells used in a storage device, such as Single Level Cell (SLC), Multi‑Level Cell (MLC), Triple‑Level Cell (TLC) or Enterprise MLC (eMLC). It indicates how many bits are stored per cell and influences performance, endurance and cost.
SLC (Single Level Cell)
Protection features
A comma‑separated list of protective characteristics that a product offers, such as resistance to dust, water, shock, heat, or other environmental factors.
Shock resistant,Vibration proof
RAID support
A comma‑separated list of RAID levels that a storage device or controller can support, such as 0, 1, 5, 10, JBOD, and other proprietary configurations. Each value represents a distinct RAID mode the system is capable of creating or managing.
Yes
S.M.A.R.T. support
Indicates whether the product supports S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology), a feature that monitors storage device health and predicts failures.
Yes
SSD Capacity 128 GB
SSD form factor
Represents the physical form factor of a solid‑state drive, indicating its size and connector type (e.g., M.2, 2.5", 3.5"). This attribute helps users identify compatibility with motherboards, enclosures, or laptops.
2.5"
TRIM support
Indicates whether the storage device supports the TRIM command, which allows an operating system to inform the drive which blocks of data are no longer considered in use and can be wiped internally. This feature improves performance and longevity on solid‑state drives by enabling efficient garbage collection.
Yes
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.
100 mm
