The HP INT (manufacturer number 4L5K1AA) is an internal, slim optical drive for desktop systems, specifically designed for use in workstations and PC enclosures with limited space requirements. The device has a height of 9.5 mm, making it suitable for slim form factors used in modern tower PCs and workstations. The product color is black, enabling visual integration into standard PC enclosures. The drive is configured as a DVD-ROM, meaning it is suitable exclusively for reading DVD media (including DVD-Video, DVD-ROM, DVD-R, DVD-RW, DVD+R, DVD+RW) without writing functions for Blu-ray or other optical formats. The interface is SATA, representing a standard connection for internal drives in desktop computers and ensuring compatible connection to the motherboard.

Applications

The drive is primarily intended for desktop computers, particularly workstations such as the HP Z2 TWR or similar systems requiring a compact form factor. It serves for data retrieval from DVD media, for example, for operating system installation, software updates, data backups, or multimedia content. Due to its low height of 9.5 mm, it is especially suitable for systems where vertical space in the enclosure is limited, such as slim-tower PCs or special workstation designs.

Functions and Equipment in Detail

The device is designed as an internal drive, meaning it must be installed inside a computer enclosure and cannot be operated externally. The DVD-ROM function enables reading of various DVD formats, including writable media such as DVD-R and DVD+R, but without writing capability. The SATA interface ensures stable and standardized data transfer with sufficient bandwidth for most applications. The height of 9.5 mm corresponds to the slim form factor, which is used in modern PC systems to save space.

Technology Explained Simply

The term DVD-ROM stands for Digital Versatile Disc – Read-Only Memory, meaning the drive can only read data from DVD media but cannot write. It supports common DVD formats widely used in industry and private applications. The SATA interface (Serial ATA) is the standard connection for internal storage devices and provides reliable data transfer. The low height of 9.5 mm allows installation in systems optimized for compact designs without requiring additional space.

Compatibility and Accessories

The drive is designed for desktop computers and is used in systems such as the HP Z2 TWR. It is compatible with SATA interfaces, which are typically available on modern motherboards and mainboards. No additional accessories or adapters are required to operate the drive in a compatible system. The drive is used exclusively in internal operation, with physical mounting in a 5.25-inch bay or a corresponding slim form factor bay.

Installation and Mounting

Installation involves mounting the drive into an available 5.25-inch bay or a slim form factor bay in the PC enclosure. The drive is secured with screws and connected to SATA data and power cables. The SATA connection requires both a data cable and a power cable, which are typically provided by the PC manufacturer or system integrator. Physical mounting requires no special tools, although basic knowledge of PC hardware is necessary to correctly perform the cabling.

Advantages in Operation

The drive offers a reliable and compact solution for reading DVD media in desktop systems. The low height of 9.5 mm enables use in systems with limited space without compromising functionality. The SATA interface ensures stable and fast data transfer, sufficient for most applications. The device is suitable for use in professional workstations, where compatibility with standard PC systems and reliability in continuous operation are important. The black product color ensures unobtrusive integration into most PC enclosures.
