Breaking Records With SSDs: 16 Intel X25-Es Do 2.2 GB/s

Conclusion

The fastest array ever? We haven’t seen any other DAS solution reaching almost 2.3 GB/s throughput.

In theory, an array that consists of 16 flash SSDs capable of delivering 200 MB/s each should be able to get to 3,200 MB/s. Unfortunately, we remained far away from this number despite all optimizations, but we still managed to outperform Samsung’s flash SSD array. That array was powered by 24 PB22-J flash SSDs. We only used 16 Intel X25-E SSDs to reach higher numbers. The primary goal was to achieve a higher sustained sequential throughput, and we’re very pleased to have hit 2.23 GB/s with our X25-E RAID versus 2.12 GB/s for the Samsung PB22-J array.
