Acasis 4-Bay USB 3.0 SATA/SAS Hard Drive Enclosure – Multi-Drive Storage Array

ACASIS USB 3.0 4-Bay SATA & SAS Drive Enclosure – External Storage Array

Acasis 4-Bay USB 3.0 SATA/SAS Hard Drive Enclosure delivers high-capacity, enterprise-style external storage for labs, offices, and multimedia workstations. Designed to accept four 2.5" or 3.5" SATA/SAS HDDs or SSDs (up to 18TB each), it supports a combined 72TB for large datasets, backups, and media libraries. Built around high-performance INIC6711 + GL3590 dual control chips and a USB 3.0 (5Gbps) USB‑C interface, the enclosure offers stable, high-throughput transfers without additional drivers.

Thermal-management features — an 80×80 mm cooling fan plus an aluminum-alloy shell with ventilated honeycomb rear — keep drives cool during sustained I/O, while a 12V/8A (96W) power supply supports concurrent multi-disk read/write. With plug-and-play compatibility across common desktop OSes and a 10-minute auto-sleep mode to preserve drive life, this enclosure is suited to IT labs, creative teams, and anyone needing dense, reliable external storage.
