Product Description
New Upgrade, Refreshed Experience
As an upgrade to the classic D4-300, the D4-320 offers several revolutionary changes while maintaining affordability. Its new design concept offers a stylish and minimalist appearance that is more aesthetically pleasing, while its underlying technology offers a qualitative leap in terms of performance, allowing users to access outstanding functionality.
Speed Boost: 100% Faster
The D4-320 utilizes the USB3.2 Gen2 protocol to achieve a data transfer speed of up to 10 Gbps, twice the speed of the D4-300 (5 Gbps). When equipped with four hard drives, the actual read/write speed can thus be measured at up to 1,016 MB/s (combined read/write with WD Red 8TB x 4). Even with just one hard drive installed, the read speed effortlessly reaches 510 MB/s (WD Red 1TB SSD). Thus, whether using multiple hard drives operating in parallel or ensuring the efficient operation of a single hard drive, the D4-320 demonstrates exceptional performance.
As desktop products are typically positioned close to users, their noise levels must be subject to strict requirements. During read/write processes using mechanical hard drives, the high-speed rotation of disks and heads can generate excess vibrations and noticeable noise, which may resonate within the product enclosure, further amplifying the overall sound level. To address this, engineers at TerraMaster have not only implemented additional vibration damping measures in this new generation of products but also have carefully designed numerous specialized sound-absorbing panels. The resulting innovative designs significantly reduce noise levels: based on rigorous testing, the new generation of products demonstrates a remarkable reduction in noise of up to 50% as compared to the previous generation’s products. In standby mode, the noise level dips below 21 dB(A), creating an exceptionally quiet use environment.
