TerraMaster D4 SSD, 4-bay USB 4 40Gbps All SSD Enclosure DAS
Blazing-Fast USB4 Performance: Utilizing the USB4 protocol, it delivers up to 40Gbps of bandwidth. In real-world tests (with four Samsung 990 PRO 4TB SSDs in RAID 0), it achieves read speeds up to 3257MB/s and write speeds up to 3192MB/s, enabling seamless handling and editing of 8K video footage.
All-Flash Architecture with 32TB Max Capacity: Features four M.2 NVMe SSD bays, supporting up to 8TB per drive for a maximum of 32TB of all-flash storage. Purpose-built for high-performance scenarios like media creation, video production, large game libraries, and as a Mac OS boot drive.
Intelligent, Quiet Cooling: Equipped with a second-generation intelligent temperature-controlled fan and four internal sensors that adjust speed based on load, ensuring sustained high performance. Optimized airflow keeps noise levels low even at full load, with standby noise below 19dB(A)—perfect for quiet creative environments.
Wide Voltage Input & Power Protection: Supports 12V-20V wide voltage input, allowing it to be powered by most laptop (19V) adapters for greater portability. Built-in advanced power protection and automatic recovery from unexpected power outages safeguard your device and data, ideal for unattended operation with servers/NAS.
Extensive Protocol Compatibility: Fully compatible with Thunderbolt 3/4/5 and USB4/3.2/3.1/3.0 protocols for seamless switching between Mac and PC. It's the ideal choice for expanding Mac mini storage or serving as high-speed cache for Windows workstations.
