UNITEK S1308B01-EU 2-Bay RAID Enclosure for 2.5 3.5 SATA HDD SSD 5Gbps USB 3.0 RAID 0/1/JBOD/PM
The UNITEK S1308B01-EU 2-Bay RAID External Hard Drive Enclosure offers a reliable and stable storage solution. It supports up to 40TB total capacity (2 x 20TB per bay). The enclosure is compatible with both 2.5" and 3.5" SATA HDDs and SSDs. It provides flexible RAID modes: RAID 0 for performance, RAID 1 for data mirroring, JBOD for combining drives, and PM (Normal) for independent drive operation. This allows you to choose the best configuration for your needs.
The enclosure uses USB 3.0 with data transfer speeds up to 5Gbps. This ensures fast backups and quick file access. It is backward compatible with USB 2.0. Excellent heat dissipation is achieved through a powerful cooling fan and an aluminum alloy housing. These features maintain optimal temperatures during operation. They enhance reliability and extend the lifespan of your drives.
Installation is tool‑free for 3.5" drives. You simply insert the drive into the tray. For 2.5" drives, screws are included for secure mounting. The enclosure is plug and play. No drivers are required on Windows, macOS, or Linux. An LED indicator provides clear status: a blue light shows power on, and a green light flashes during data transfer. An ON/OFF switch adds convenience.
The enclosure includes a robust 12V/4A power adapter. It features triple protection: overcurrent, short‑circuit, and overvoltage protection. An auto sleep mode activates after 30 minutes of inactivity. This conserves energy and extends the life of connected devices. Silicone anti‑slip pads keep the enclosure stable on your desk. The compact dimensions are 196mm x 126mm x 92mm.
This enclosure is ideal for creative professionals, IT administrators, and home users who need large, secure storage. Use it for video editing, system backups, media libraries, or data archiving. The RAID 1 mode ensures your data is safe even if one drive fails. RAID 0 maximizes speed for performance‑critical tasks.
