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.
Sleek, ultra compact design complements your Mac or PC
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.
Lightning fast performance with Thunderbolt 2
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.
Generous data storage capacity with four 3.5in drive bays
Build an external storage solution that meets your continually changing needs. You'll have ample storage to off-load large data or back-up large files. You can configure the four 3.5in drive bays to your own requirements, with your own choice of hardware RAID configuration.
Accelerated performance and security with hardware RAID
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).
Drive protection with sleek durable housing
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.
Added flexibility and scalability with daisy chain
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.
