ACASIS Dual-Bay USB-C RAID Enclosure for 2.5″ SATA HDDs & SSDs

ACASIS Dual Bay 2.5" USB-C to SATA HDD/SSD RAID Enclosure delivers an affordable, portable solution for expanding and protecting your storage with flexible RAID options. Designed for two 2.5" SATA HDDs or SSDs (7–9.5mm), the enclosure supports up to 6TB per disk and offers four RAID modes so you can prioritize speed, capacity, or redundancy.

Using a USB 3.0/USB‑C interface with UASP support, it provides up to 5 Gbps transfer bandwidth, dual-disk simultaneous read/write, and an aluminum shell that helps dissipate heat during sustained transfers. An auxiliary DC power port ensures stable operation under heavy loads, and an intelligent 10‑minute sleep mode reduces power draw and prolongs drive life.

Features and Benefits

• Supports two 2.5" SATA HDD/SSD (7–9.5mm) with up to 6TB per disk.
• Four RAID array modes (switchable) to choose between performance, capacity, or redundancy.
• USB 3.0 / USB‑C interface with UASP acceleration for up to 5 Gbps data transfer.
• Dual-disk simultaneous read and write for faster copying and multi-disk workflows.
• Auxiliary DC power port for stable dual-disk operation under high load.
• Aluminum shell for improved durability and heat dissipation.
• Intelligent auto-sleep after 10 minutes to save power and extend drive life.

Product Q&A

• Q: Which drive sizes and thicknesses does this enclosure support?
  A: It supports 2.5" SATA HDDs and SSDs with thickness from 7mm to 9.5mm.
• Q: What RAID modes are available and why would I use them?
  A: The enclosure offers four RAID modes (user-selectable). Use RAID 0 for maximum speed, RAID 1 for mirroring and redundancy, and the other modes to balance capacity and fault tolerance depending on your needs.
• Q: Do I need external power to use both drives?
  A: For single-drive data transfer you can often rely on the host USB port, but using two drives or RAID modes may require the included DC power supply for stable operation—there is an auxiliary DC power port for this purpose.
• Q: What transfer speeds can I expect?
  A: The device uses a USB 3.0 / USB‑C interface with UASP acceleration supporting up to 5 Gbps theoretical throughput; real-world speeds will depend on host interface and installed drives.
• Q: Is the enclosure plug-and-play?
  A: Yes. ACASIS states it is compatible with Windows, macOS and Linux and works without additional drivers for most systems.
