Yottamaster FS2U3 Dual Bay Drive Enclosure 2×16 TB 40mm Fan USB 3.0

Dual Bay Enclosure for 2.5 and 3.5 Drives

The Yottamaster FS2U3 is an aluminum dual-bay enclosure that accepts both 2.5 and 3.5 inch SATA hard drives or SSDs. Each bay supports up to 16 TB for a combined maximum of 32 TB of raw capacity. It connects to a host via USB 3.0 Type-B and includes a 12V 2A power adapter. A 40mm temperature-controlled fan provides active cooling while the alloy body aids passive heat dissipation.

Suits High-Capacity Archives

This enclosure fits users who need to access two large SATA drives simultaneously without a hardware RAID controller. It works well for video editors, archivists or small offices building direct-attached storage pools up to 32 TB. Builders who require hardware RAID 0, 1 or JBOD modes managed by the enclosure itself should consider a different model. Systems limited to USB 2.0 ports will not reach the 6 Gbps SATA III link speed.

Non-RAID Design Requires Software Management

The FS2U3 is explicitly a non-RAID unit; it presents each drive independently to the operating system. Any striping, mirroring or parity must be configured through software tools on the host computer. This single characteristic determines whether the enclosure matches a workflow that relies on hardware RAID offload or one that prefers host-based volume management.
