I have a chance to test Micron RealSSD™ P320h. Initially I was expecting a good performance, but you know, how big could be a difference with other products on market? PCIe SSD market is getting crowded, and every company is trying to show the best performance. And at the end, there is a single PCIe slot, single controller, we are probably about to reach limits of these components.
And this is 16KiB blocksize, which gives us 200.000 random reads IOP/sec, again in 16K blocks (not 512 or 4096 usually used in public benchmarks).
