Supporting 12Gb/s SAS III and SATA III, it handles modern high-capacity drives up to 14TB in demanding server, NAS, and workstation deployments. The trayless design allows drives to be inserted and removed without a separate caddy, minimizing installation time and eliminating tray management overhead. The aluminum front bezel includes a metal key lock mechanism that physically secures installed drives against unauthorized removal — essential for shared rack environments. An 80mm fan with adjustable speed control and ultra-quiet operation maintains thermal stability under continuous load. Full aluminum integrative-shaping construction provides structural rigidity and maximum passive heat dissipation. RAID 0/1/5/10 supported with a compatible external controller. Ideal For Maximum Density Server & NAS Storage — Five hot-swap bays in three 5.25" slots for the highest drive density per bay Secure Rack Deployments — Key lock bezel prevents unauthorized drive access in shared environments RAID Arrays — Compatible with external controllers for RAID 0/1/5/10 configurations Video Editing & Media Production — 12Gb/s throughput for HD/4K video and large dataset storage Enterprise & Data Center Builds — Heavy-duty aluminum for continuous 24/7 operation Variant Options Black — MPN: BPN-DE350HD-BLACK Blue — MPN: BPN-DE350HD-BLUE Red — MPN: BPN-DE350HD-RED Silver — MPN: BPN-DE350HD-SILVER Specifications Bay Conversion — 3× 5.25" external to 5× 3.5" internal Drive Support — 3.5" SAS I/II/III, SATA I/II/III HDD Max Drive Capacity — Up to 14TB Transfer Rate — Up to 12Gb/s Hot-Swap — Yes — trayless Security — Metal key lock on aluminum front bezel Cooling — 80mm fan with adjustable speed control Construction — Full aluminum (integrative shaping) LED — Multi-function blue LED display RAID Support — Yes (requires external RAID controller) Colors — Black, Blue, Red, Silver
