NGFF (Next Generation Form Factor), as the name suggests, is the standard of Form Factor. It is tied with NGFF for 2.5 "instead of PCIe. (In addition, NGFF has now been renamed M.2. We 'd better keep pace with the times and change it to M.2 .)PCIe is a bus standard, tied with SATA.NVMe is a new transmission standard for hard disks and replaces the current AHCI.Why do people always associate NGFF/M.2 with PCIe/NVMe? This is because the SSD in

NVMe SSDs are the evolution direction of storage disks, and NVMe SSDs have more than ten times the performance growth compared to SATA/SASSSD. This is mainly due to the NVMe SSD Multi-queue technology, through the multi-queue technology can be IO access parallelization, so as to improve the overall performance of the system. in theNVMein the storage ecosystem,Ss

data from the Flash block to avoid data errors.1.6 Data Hold (Retention)Because of the charge loss, the data on the Flash block is subject to potential problems, and the FTL needs to relocate the data.2. NVMe Disk Write Amplification statisticsFrom the introduction above you can see that there are many kinds of additional write operations inside the SSD, in order to analyze the impact of these write operations on the user write requests, you need to

The AHCI controller interface can only handle 1 command Queues instruction

What the hell is an RDMA? It is believed that most children who do not care about high-performance networks do not know much. But the advent of nvme over fabrics let the storage have to take time to look at this thing, this article will introduce the RDMA I know.RDMA (Remote Direct memory access) is intended to directly access the host's memory at the remote, without the need for host involvement . For example, when both the host and client are equipp

as flash capacity continues to rise, prices continue to fall, and applications are increasing, pushing flash storage systems to replace traditional disk systems. Compared to traditional disk systems, storage-system design considerations are subject to significant changes due to changes in storage media. This change is directly reflected in the change of storage system software architecture, that is, the so-called storage software stack reconfiguration. For Sata/sas SSDs , the performance of the
