Notes from observed performance:

Give this a minute to sink in – this is a NAND-flash based SSD, turning in sub-20 microsecond latencies, not only average but sticking <30us all the way out past five 9's! To give this some added perspective, NAND SSDs typically run at 2-3x of these latencies!

Also worth noting that while the random write performance is amazing at QD1, that performance does not really scale up at all in the higher queue depths, meaning that higher QD's only result in higher latency, with minimal gain in IOPS (zero gains past QD2). Random reads fare better, behaving like typical NAND, climbing past 675k IOPS at QD32 and ultimately reaching 750k by QD128.
