Let me back up a little – they’re not really slow. When Intel compared its standard NAND flash based PCIe SSD to a similar SSD based on 3D XPoint memory, the XPoint model ran 7-8 times faster, which is very impressive. Intel demonstrated that at the Intel Developer Forum (IDF) last August and several times since then.
But Intel and Micron have been boasting since its introduction that 3D XPoint Memory is 1,000 times as fast as NAND flash. How do you get from a 1,000 times speed advantage down to a speed improvement of only 7-8 times?
That’s what the graphic in this post will explain. The small rendition above is just Continue reading
