Product Features
Technical Overview
This DAS array features a two-bay architecture, with both bays populated by hard drives to achieve the total 4 TB installed capacity. The storage subsystem is built around a Serial ATA/300 controller, which supports RAID levels 0, 1, and JBOD, allowing administrators to tailor the array for performance, redundancy, or independent drive operation based on specific workload requirements.
Connectivity is handled through a single USB 3.0 host interface, providing up to 5 Gbps theoretical transfer speeds for fast data access and backup operations. This universal interface ensures broad compatibility with modern Windows and macOS computers. The drive interface remains Serial ATA/300, ensuring stable communication with the installed hard drives.
Relevant factors for this section include Number of Hard Drives Supported, Number of Hard Drives Installed, Total Hard Drive Capacity Installed, Number of Total Expansion Bays. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
Key Product Advantages

Deployment / Use Cases
This DAS array is optimally deployed as a dedicated storage expansion unit for individual workstations or as a local backup target for small office servers. Its simplicity and performance make it suitable for environments where network-attached storage (NAS) is unnecessary or where direct, high-speed access is preferred.
Common use cases include serving as a primary storage repository for video editing workstations, housing large design files for creative teams, functioning as a local backup destination for critical server data using bundled software, or expanding the storage capacity of a desktop used for data analysis or archival purposes. The compact size allows it to fit neatly on a desk or in a small server closet.
