Promise Technology on Monday announced the immediate availability of the Pegasus J2, the world’s smallest and fastest ultra-portable Thunderbolt storage device. The J2 is able to achieve transfer speed as high as 750MB/s in a device the size of a smartphone. Quite naturally, the Pegasus J2 sets price records in addition to performance records.

 

The Promise Pegasus J2 is a pocket-sized, external storage device that is available in 256GB and 512GB capacities. The Pegasus J2 is based on two  high-end mSATA solid-state drives operating in RAID 0 (stripe) with up to 750MB/s read speed and is compatible with all Thunderbolt enabled Apple Mac personal computers. To achieve maximum throughput of over 750MB/s requires using the Pegasus J2 power adapter plugged into a power outlet. The J2 is also designed to run without the power adapter, instead using Thunderbolt bus power, but with read speeds reduced to ~250 MB/s and write speeds of around 110 MB/s.

“We are very excited to deliver this new expansion peripheral that helps continue our leadership of Thunderbolt enabled storage devices. The new Pegasus J2 brings unprecedented performance and flexibility to consumers and creative media professionals seeking a high-performance video storage solution. Designed for extreme speed and portability, these products provide a dynamic expansion of our award winning Pegasus family of high-performance storage solutions developed for the rich media markets,” said James Lee, chief executive officer of Promise Technology.

Promise Pegasus J2 SSDs are now available for order from the Apple online store and through the Promise global network of distributors and value added resellers. The 256GB version costs $799, whereas the 512GB model retails for $1499.
