Scalable Informatics has built its fastest JackRabbit (JR) to date, with a read speed of 2.5 GB/s and a write speed of 2.5 GB/s. This exceeds the performance any unit we've tested to date!

"This is the fastest unit in this size and price class we've ever offered. Its read/write performance beats any unit we've ever tested. Its price/capacity is in the $1000/TB region, and price/performance are among the best in the industry. You don't need to spend a great deal of money to get this sort of performance — at least, not with Scalable Informatics," said CEO Joe Landman, Ph.D.
