How many SSDs does it take to saturate PCIe Gen 3? Would you believe 16 drives?

It’s now possible to conduct some interesting performance tests on real PCIe Gen 3 products and the video below shows you a PCIe Gen 3 RAID card talking to 16 SSDs, which is the number of drives needed to saturate a setup based on an Intel Sandy Bridge processor and chip set. The result is 6600 Mbytes/sec of throughput—about 90% of the theoretical maximum. With tweaking, that number might go up to 95%. Just watch the video.
