Dual-Bay Aluminium Enclosure for SATA Drives

The Yottamaster FS2U3 holds two 2.5-inch or 3.5-inch SATA hard drives or SSDs, each up to 16 TB, for a total of 32 TB of direct-attached storage. It connects through a USB 3.0 Type-B port and requires no hardware RAID configuration, making it suitable for users who need simple, high-capacity external storage for archives or media libraries.

Thermal Management Under Continuous Operation

An aluminium-alloy chassis works with a temperature-controlled 40 mm fan to dissipate heat during sustained read or write sessions. Four vibration-absorbing feet keep the unit stable and quiet on a desktop, so the enclosure remains cool and unobtrusive even when both bays are active for long periods.

Interface Throughput and Protocol Limits

The internal SATA III interface runs at up to 6 Gbps per drive, while the single USB 3.0 link shares that bandwidth between the two bays. Real-world transfer rates will therefore sit below the SATA maximum and vary with drive performance, cable quality and host controller implementation.

Questions about this item

How loud and warm does the aluminum enclosure with its 40 mm fan get when both bays run continuously?

The aluminum-alloy shell and intelligent temperature-control fan are designed for low-noise cooling; the 12 V 2 A power input and 150 W supply keep drives running cool during all-day use.

What host connection and drive types do I need to use both 2.5″ and 3.5″ SATA drives at once?

Connect the enclosure via USB 3.0 Type-B to a host with a USB 3.0 port; it accepts two 2.5″ or 3.5″ SATA HDDs or SSDs up to 16 TB each, no RAID hardware required.

Will the USB 3.0 Type-B link and SATA III 6 Gbps protocol work reliably with older SATA II mechanical drives I still have?

Yes — the SATA III interface is backward compatible with SATA II drives, and USB 3.0 falls back to USB 2.0 speeds if plugged into an older port.
