Intel Optane SSD 800P - All You Need To Know
The Intel Optane SSD 800P can technically be used as a data caching accelerator like Optane Memory, but these drives are designed to be used as boot volumes to boost performance of mainstream systems. When you look at their specifications, however, you may wonder where the Intel Optane SSD 800P fits in a market where NVMe M.2 gumsticks offering >3GB/s of throughput are increasingly more commonplace. Rest assured, the Intel Optane SSD 800P performs well with the day-to-day computing workloads that matter most for the majority of consumer user cases.

SSD that use 4 lanes of PCIe connectivity and offer peak transfers in excess of 3GB/s, but the Optane SSD 800P is all about low latency and achieving high performance with 4K transfers at low queue depths. Super-fast large, sequential transfers were not a priority here – more on this later.
Intel hasn’t revealed much about the controller architecture, but we have detailed 3D XPoint a few times in the past. We’ll explain what makes 3D XPoint different compared to traditional NAND on the next page, but to quickly summarize, it is a relatively new memory technology that offers performance and latency characteristics approaching DRAM, but at capacities and prices closer to NAND flash memory. 3D XPoint is also non-volatile like NAND.
