You can now buy the first products to use the Thunderbolt technology from the Apple Store: an Apple Thunderbolt cable and an external RAID system from Promise called Pegasus (just be sure to download and install the recent Thunderbolt firmware update before you take advantage of these new products).
The Apple Thunderbolt cable costs $49 at the Apple Store and supports data transfer with two independent channels of 10 Gbit/s each.
You’ll have to buy this cable if you want to use Thunderbolt peripherals, use Target Disk Mode between two Macs that have Thunderbolt, or use an iMac as a display for a MacBook Pro that has Thunderbolt.
There are four versions of the Promise Pegasus external RAID system, each with different hard drive sizes and transfer speed. Note that you’ll need to buy the Apple Thunderbolt cable separately and each unit has two Thunderbolt ports.
- Promise Pegasus R4 4TB (4x1TB): For $999 you get four hard drives at 1 TB each with a transfer rate of 500 MB/s.
- Promise Pegasus R4 8TB (4x2TB): If you want double the capacity spend $1,499 and you’ll get four hard drives at 2 TB each at the same transfer rate of 500 MB/s.
- Promise Pegasus R6 6TB (6x1TB): If you need a higher transfer rate then you’ll can get this model with 800 MB/s transfer rate and six hard drives at 1 TB each for $1,499.
- Promise Pegasus R6 12TB (6x2TB): Spend $1,999 and you’ll get six hard drives at 2 TB each.
There are some other unique features about the Pegasus systems, most notably their management software that’s designed to make it easy to manage the multiple hard drives which have come configured for “fast, easy set-up to store music, photos, videos and documents or ingest and edit production video.” In addition, the hard drives are hot-swappable which makes them suitable for a server as well as providing the fast speeds necessary for video work.
