Netac has announced the launch of the K393, an enterprise-class 3.5-inch portable hard drive designed for high-capacity storage requirements. The device is based on a traditional 3.5-inch mechanical hard drive and is equipped with a USB-C interface for data transfer, along with a dedicated DC-in power supply connection to ensure stable operation.
The K393 is available in multiple configurations, offering storage capacities of 12TB, 16TB, 20TB, 24TB, and 28TB. According to Netac, the drive delivers sequential read speeds of up to 270MB/s, making it suitable for scenarios where large files need to be moved or accessed quickly. The inclusion of a 12V/2A power adapter ensures that the drive receives adequate power, and the package also includes both USB-C to USB-C and USB-C to USB-A cables for broader device compatibility.

In terms of design, the K393 adopts an aluminum alloy housing that is both protective and functional. The surface incorporates embossed side stripes, providing grip while also assisting with heat dissipation. Additional air vents are positioned around the enclosure to help maintain consistent airflow and thermal management during extended use. This construction aims to deliver a balance of durability and cooling efficiency for enterprise-level workloads.
Despite being presented as an enterprise-class mobile hard drive, the K393 is covered by only a one-year warranty. This is shorter compared to the warranties commonly provided with enterprise storage products, which may raise concerns for businesses or professionals looking for long-term support on high-capacity drives.
Netac’s K393 enters a segment where demand for large-capacity portable storage continues to grow. Content creators, enterprises, and professionals working with extensive datasets often require external solutions that combine performance with reliability. With capacities reaching up to 28TB, the K393 is positioned to serve users needing both portability and volume, though its limited warranty may influence purchasing decisions.
By offering a wide range of storage options, modern connectivity through USB-C, and a reinforced design, Netac aims to provide a solution for users handling large-scale data management outside traditional data center setups. The device is expected to become available across major distribution channels in the coming weeks.
