Overview
The S352BU33HR 2-Bay RAID Enclosure lets you build an external RAID array using two 3.5” SATA hard drives, and add it to your computer through USB 3.0.
For optimal performance from your SATA III drives, the external RAID enclosure supports a UASP-enabled USB 3.0 host connection, which performs up to 70% faster than conventional USB 3.0 when paired with a UASP compatible host controller. (See UASP testing results below for more detail).
The RAID enclosure also lets you connect additional USB 3.0 devices to your computer, through an integrated 2-port USB 3.0 hub conveniently mounted on the front of the enclosure. The easy-to-reach hub also has fast charging capabilities, so you can charge your iPad, smartphone or other mobile devices as quickly as you would through a direct wall outlet connection.
To help maintain safe operating temperatures for your hard drives, the 2-drive enclosure features a built-in cooling fan to ensure proper air circulation and prevent your SATA drives from over-heating.
The enclosure features an integrated hardware RAID controller, which gives you the options you need to set up the array that best suits your storage application, including JBOD, Spanning, RAID 0, and RAID 1.
To ensure compatibility with your computer system, the S352BU33HR supports all of the leading operating systems, including: Microsoft Windows® (8/7/Vista/XP/Server 2008/Server 2003), Apple® OSX (10.9/10.8/10.7/10.6), Linux, and Google Chrome OS™.
The S352BU33HR is backed by a StarTech.com 2-year warranty and free lifetime technical support.
Improved Performance with UASP
UASP is supported in Windows 8, Mac OSX (10.8 or above), and Linux. In testing, UASP performs with a 70% faster read speed and 40% faster write speed over traditional USB 3.0 at peak performance.
At the same peak in testing UASP also shows an 80% reduction in required processor resources.
Testing results were obtained using an Intel® Ivy Bridge system, a UASP-enabled StarTech.com Enclosure, and a SATA III solid state drive.
The StarTech.com Advantage
- Save time, with file transfers up to 70% faster than traditional USB 3.0 when used with a UASP-supported host
- Charge your iPad and other mobile device faster than standard USB 3.0, with fast charge port
- Preserve system resources using hardware-based RAID instead of software
Applications
Build an external RAID 1 array for data redundancy, to protect against drive failure when working with important data
Externally work with very large files securely in video editing or photography applications
Quickly transfer large data files from your computer to a secure external RAID enclosure

Frequently Asked Questions
Before You Buy
To determine if your hard drive will work in this enclosure, on the product page, click the Technical Specifications tab, and do the following:
- Make sure that the enclosure supports the storage size of your hard drive. If the storage size of your hard drive is larger than what the enclosure was tested with, the hard drive will likely still work with the enclosure.
- Confirm that your hard drive uses the same interface type as the enclosure. For example, IDE, SATA, or M.2.
- Make sure that the enclosure supports the physical size of your hard drive, such as 2.5 inches or 3.5 inches.
- Make sure that the enclosure supports the height of your hard drive. For example, 9 mm or 15 mm.
- Verify that the power consumption of your hard drive doesn’t exceed the power output of the enclosure. If you’re using multiple hard drives, make sure that the combined power consumption of all of the hard drives doesn’t exceed the power output of the enclosure.
Note: Not all StarTech.com devices support each of the RAID modes described below. For more information on the RAID modes that your device supports, refer to the manual or the StarTech.com product page.
Redundant Array of Independent Disks (RAID) is a virtual disk technology that combines multiple physical drives into one unit. RAID can create redundancy, improve performance, or do both.
RAID should not be considered a replacement for backing up your data. If critical data is going onto a RAID array, it should be backed up to another physical drive or logical set of drives.
The following are terms that are normally used in connection with RAID:
- Striping: data is split between multiple disks.
- Mirroring: data is mirrored between multiple disks.
- Parity: also referred to as a checksum. Parity is a calculated value used to mathematically rebuild data.
Different RAID levels exist for different application requirements.
Refer to the following table for the list of RAID modes offered by some StarTech.com products:
| RAID mode | Description | Operation | Advantages | Disadvantages | Recovery |
| RAID 0 | Striped disks | Data is split evenly between two or more disks. | Large size and the fastest speed. | No redundancy. | If one or more drives fails, this results in array failure. |
| RAID 1 | Mirrored disks | Two or more drives have identical data on them. | A single drive failure will not result in data loss. | Speed and size is limited by the slowest and smallest disk. | Only one drive is needed for recovery. |
| RAID 3 | Striped set with dedicated parity | Data is split evenly between two or more disks, plus a dedicated drive for parity storage. | High speeds for sequential read/write operations. | Poor performance for multiple simultaneous instructions. | A single drive failure will rebuild. |
| RAID 5 | Striped disks with distributed parity | Data is split evenly between three or more disks. Parity is split between disks. | Large size, fast speed, and redundancy. | The total array size is reduced by parity. | A single drive failure will rebuild. |
| RAID 10 | 1+0; Striped set of Mirrored Subset | Four or more drives are made into two mirrors that are striped. | Larger size and higher speed than RAID-1, and more redundancy than RAID-0. | No parity. | Only one drive in a mirrored set can fail. |
| JBOD | Just a Bunch Of Disks | Any number of drives are accessed independently by the operating system. | Software RAID modes can be used. | Hardware RAID may have better performance. | N/A |
| Big | Spanning or Concatenation | Data is written on one drive until it is full, and then the next drive(s) until it or they are full. | Creates a very large and simple array. |
No redundancy. |
N/A |
| Clone | RAID 1 + Spare |
Two drives have identical data, plus one drive is used for rebuilding in case of a primary array failure. |
Seamless operation when one drive fails in a RAID-1 array. | Spare drive is not accessible to the user. | Only one drive is needed for recovery. |
