Product ID: S354SMTB2R
Creative professionals, from digital content creators to video editors, have extreme demands for external storage requiring both high capacity and high speed. Now, you get the best of both worlds with the 4-bay Thunderbolt 2® hard drive enclosure. It gives you 4 customizable 3.5in drive bays, 20Gbps speed with Thunderbolt 2, and the accelerated performance and security of hardware RAID.
Finally, you get the throughput you demand. You can add four 3.5” SATA III hard drives to your Mac or PC using your Thunderbolt port, and build an external RAID array for enhanced performance and data security.
The 4-bay Thunderbolt 2 drive enclosure is big on storage capacity and speed, yet small in size - at only 4.6” (116 mm) wide and 6.2” (158 mm) high. Its sleek, ultra compact design in high quality aluminum makes it the perfect companion for your Mac, MacBook Pro®, Dell™ XPS, Dell Precision or other device.
Time is money, so just imagine how much you can save with Thunderbolt 2 performance. Stream data quickly. Work effortlessly with raw media files.
Giving you 20Gbps of throughput, you can transfer data to and from your external drives faster than ever before. This superior performance makes Thunderbolt 2 the ideal external solution for high-resource intensive storage applications including high-resolution video editing and photography in your production and post-production environments.
The drive enclosure supports SATA III, II and I specifications, to enable faster data transfer speeds of up to 6Gbps. You can also use a 2.5in to 3.5in SSD adapter (25SAT35HDD) to add an SSD to your array and utilize Hyper Duo, giving you near-SSD performance at HDD capacities.
Build an external storage solution that meets your continually changing needs. You’ll have ample storage capacity to off-load large data or back-up large files. (HDDs are not included with the enclosure.) You can configure the four 3.5in drive bays to your own requirements, with your own choice of hardware RAID configuration.
The Thunderbolt 2 enclosure supports hardware RAID giving you increased performance and protecting your valuable data at the same time, with support for RAID modes: JBOD / 0 / 1 / 1+0 . The included software lets you monitor your array as well as set your hardware RAID configuration. Hardware RAID increases your performance as data is off loaded to the enclosure, freeing up system resources for more process intensive tasks like file rendering (3D/Video).
To ensure peak performance, the Thunderbolt 2 enclosure maintains an ideal operating environment to protect your drives. The enclosure features a built-in fan for improved air circulation and an aluminum housing that maximizes heat dissipation while providing rugged durability.
Leverage the Thunderbolt daisy chain port. You can connect up to 6 additional devices such as monitors, docking stations, or additional external drives -- the perfect solution for Ultrabooks.
The S354SMTB2R 4-bay Thunderbolt 2 enclosure is backed by a StarTech.com two year warranty and free lifetime technical support.

Live Chat (opens in new window)When you troubleshoot issues with a hard drive enclosure, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
To test your setup components, try the following:
When you test the hard drive and hard drive enclosure, it is recommended that you do the following:
Note: Formatting a hard drive erases all of the data on it. Make sure that you back up all of your data before you reformat the hard drive.
Note: A formatted hard drive will not show up in Computer or My Computer until it has a drive letter assigned to it.
In order to rebuild a RAID array, you need to replace a physical drive with an identical drive on the same RAID controller. Although standard RAID levels are generally agreed upon throughout the industry, the implementation varies between manufacturers. RAID arrays are typically not accessible when they are moved to another controller, and data may be unrecoverable if the drives are out of order or have been formatted or accessed by another RAID controller.
If a RAID controller has failed, you should get the exact same model of RAID controller.
Note: If a drive or drives were damaged, it is possible that the RAID array may be permanently unrecoverable.
RAID should not be considered a replacement for backing up your data. If critical data is going onto a RAID array, you should back up the data on another physical drive or logical set of drives.
With the following RAID modes, recovery is possible using the same StarTech.com product. Refer to the following table for the appropriate method to use to recover your RAID array.
RAID mode | Max # of failed drives | Procedure |
RAID 1 | Only one drive is needed for recovery. |
The array will rebuild and is accessible during the rebuilding process. |
RAID 3 | Single drive failure will rebuild. |
Note: Do not change the order of the drives.
|
RAID 5 | Single drive failure will rebuild. |
Note: Do not change the order of the drives.
|
RAID 10 | Only one drive in a mirrored set can fail. |
Note: Do not change the order of the drives.

To determine if your hard drive will work in this enclosure, on the product page, click the Technical Specifications tab, and do the following:
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:
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. |
