This USB 3.1 dual-bay drive enclosure makes it easy to add high-capacity, high-performance external data storage to your laptop or desktop computer. The dual-bay RAID enclosure supports two 3.5? SATA hard drives with ultra-fast data transfer speeds and configurable RAID modes.
High-speed, high-capacity data storage
Create a high-capacity, external data storage solution with support for two 3.5? HDDs, SSDs or SSHDs. This 2-bay 3.5" drive enclosure delivers fast file transfer rates up to 10Gbps with USB 3.1 Gen 2 performance. It supports SATA I, II and III and is enhanced with UASP to maximize the performance and speed of your SATA III drives.
The dual-drive RAID enclosure provides an effective solution for creative professionals, office employees, researchers, and medical personnel to store, access, back up, and protect important files. It gives you the peace of mind of knowing that your data is safe, secure, and protected.
Increase performance and data redundancy through RAID
With multiple RAID options, you can gain increased storage size, performance, or redundancy. The enclosure supports RAID 0, RAID 1, JBOD and SPAN (BIG), which enables you to choose your preferred backup mode and customize your drive arrangement based on your storage requirements.
Designed for reliability and versatility
To maximize both durability and reliability, the external RAID enclosure features an aluminum and plastic housing with a metal hard-drive mounting tray. It also features a built-in fan, to help dissipate operating heat and maintain an optimum operating environment for drive protection.
The dual-bay drive enclosure includes both a USB-C and USB-A cable for flexible use with the latest laptops and tablets, equipped with a USB-C™ port, Thunderbolt™ 3 USB-C port, as well as legacy devices. The enclosure is OS independent, requiring no additional software or drivers.
The S352BU313R is backed by a StarTech.com 2-year warranty and free lifetime technical support.

Ports & interfaces | |
USB connectivity The product has USB connector. | |
USB version Universal Serial Bus (USB) is an industry standard developed in the mid-1990s that defines the interface used for connection, communication and power supply between computers and electronic devices. Every new version - for example 1.1, 2.0, 3.0 - is much faster than the previous one. | 3.2 Gen 2 (3.1 Gen 2) |

RoHS compliance The Restriction of Hazardous Substances (RoHS) Directive aims to restrict certain dangerous substances commonly used in electrical and electronic equipment. Any RoHS compliant product is tested for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE). PBB and PBDE are flame retardants used in several plastics. For Cadmium and Hexavalent chromium, there must be less than 0.01% of the substance by weight at raw homogeneous materials level. For Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at raw homogeneous materials. Any RoHS compliant component must have 100 ppm or less of mercury and the mercury must not have been intentionally added to the component. In the EU, some military and medical equipment are exempt from RoHS compliance. | |
Certification | CE, FCC, REACH |
Performance | |
Data transfer rate Rate at which data can be transferred. Usually expressed in units per second. May vary with network configurations. | 10 Gbit/s |
Chipset Set of electronic components in an integrated circuit that manages the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance. | ASMedia - ASM1352R |
UASP support | |
Mean time between failures (MTBF) Statistical model used to indicate product/mechanism reliability; expressed in hours and percentage of duty cycle. This number (in hours) does not indicate the mean time before failure for a single unit/mechanism. | 100000 h |
Plug and Play Indicates whether this product supports is "plug and play". Plug and play is hardware or software that, after being installed ("plugged in"), can immediately be used ("played with"), as opposed to hardware or software which requires configuration. |
