Transportable RAID enclosure for creative workflows

The Yottamaster FS2RU3 is a two-bay hardware RAID enclosure that accepts 2.5 and 3.5 inch SATA hard drives and SSDs. It connects through a USB 3.0 Type-B port and includes a 12V2A power adapter. An aluminum chassis and a 40mm silent fan keep drives cool during extended sessions.

Upgrade from single-drive USB enclosures

Moving from a single external drive to this dual-bay unit adds hardware RAID 0 for speed, RAID 1 for mirroring, SPAN for combined capacity and PM for independent drive access. The jump is worth it when a project needs up to 36TB of protected or striped storage without relying on software RAID.

Fits desktop workstations with USB 3.0 ports

The enclosure needs an available USB 3.0 Type-A or Type-C port and mains power for the supplied adapter. Two vibration-absorbing feet keep it stable on a desk. Removable aluminum trays with included screws let you swap drives without tools, freeing internal drive bays for other components.

Questions about this item

What drive sizes and maximum capacity per bay does the FS2RU3 enclosure support?

It accepts both 2.5" and 3.5" SATA drives, with up to 18TB per bay and 36TB total across the two bays.

How do I set the RAID mode on the FS2RU3, and which step is often missed?

Use the hardware RAID switch on the enclosure to choose RAID 0, RAID 1, SPAN, PM or CLONE before powering on; the step people miss is setting the mode while the unit is off, then restarting.

What cooling and power components will need attention over time on the FS2RU3?

The 40mm silent fan and the 12V 2A AC adapter are the parts most likely to require cleaning or replacement after extended use.
