The world?s smallest Thunderbolt? attached storage easily fits in your pocket! The Apple and Windows certified PROMISE Pegasus J2 Series Thunderbolt storage solution delivers the power of two mSATA SSD to content creators and power-users who work on-the-go. Along with Thunderbolt connectivity, the Pegasus J2 is super portable ? it'll even fit in your pocket.

Massive Performance Leap for Portable Storage
Packing an amazing amount of performance, this compact solution takes full advantage of Thunderbolt technology. It can achieve 550 MB/s write performance and 750 MB/s* read performance while connected to an external A/C power source.

Ultra-portable for Content Creators On-the-go
Weighing only 140 grams and measuring roughly about the size of a deck of cards, the Pegasus J2 fits in the palm of your hand, your pocket, backpack or sling bag. It's ideal for on-location editing or other demanding creative projects.

Power Adapter Optional
You're free to power the Pegasus J2 from an A/C source or from the Thunderbolt port of your computer. While an external A/C power source delivers maximum performance, you can still achieve up to 110 MB/s writes and 270 MB/s reads when using bus power. Plus, you can conveniently switch between using AC Power and Thunderbolt Bus Power without interrupting your work.

Much More is Possible with Pegasus
If you need to work with more than one OS, run a virtual machine from the Pegasus J2 and save disk capacity on your primary system. Users can then connect to the Pegasus J2 and boot the VM OS much faster. Additionally, the amazing speed and portability of the Pegasus J2 is perfect for business travellers to quickly and securely backup their mail and important files when out of the office.

About Thunderbolt Technology
Thunderbolt? technology is a high-speed, dual-protocol I/O technology developed by Intel and Apple, designed for performance, robustness, simplicity, and flexibility. Thunderbolt? delivers two channels of 10Gb/s (1.25GB/s) per port of blistering performance. The huge bandwidth allows digital media professionals to edit HD video stored on the Pegasus with NLE software (such as Apple?s Final Cut or Adobe?s Premiere), improve work flow efficiency, save time and money.
* To achieve maximum throughput of over 750MB/s requires using the Pegasus J2 power adapter plugged into a power outlet.
