Riding on the PCIe bus directly to the CPU will deliver amazing latency numbers, but the motherboard we used for this test incorporates a PLX PCIe switching chip that may or may not get in the way of delivering the best performance possible. Over the next few weeks we've perform more tests on motherboards without PCIe switching.
After running through several products with 20nm MLC and 19nm TLC flash, keeping write latency under 13 ms is like finding a new old stock Walter Payton jersey on EBay. We thought it was gone forever, but it appears PCIe based NGFF is the answer to NAND flash latency increases.
Of every test we'll show today the PCMark Vantage performance is the most telling of what you'll expect at home, in your system with the SanDisk A110.
The next generation in NGFF is more than just a form factor, it's a leap in performance.
