What does nvme patch for win7 mean?

nvme patch for win7 means that win7 does not support the nvme protocol. In order to make win7 support nvme solid state drives, an nvme patch needs to be applied; nvme is a logical device interface specification, which is similar to AHCI and is based on devices. Bus transfer protocol specification for a logical interface used to access non-volatile memory media attached over the PCI Express (PCIe) bus.

What does nvme patch for win7 mean?

nvme patch forwin7 means that win7 does not support the nvme protocol. In order to make win7 support nvme solid state drives, you need to apply the nvme patch. Basically every SSD manufacturer will release this patch, you can choose it according to your own SSD.

NVM Express (NVMe), or Non-Volatile Memory Host Controller Interface Specification (English: Non Volatile Memory Host Controller Interface Specification, abbreviation: NVMHCIS), is a logical device interface specification. It is a bus transmission protocol specification based on the device logical interface (equivalent to the application layer in the communication protocol) similar to AHCI. It is used to access non-volatile memory media (such as flash memory) attached through the PCI Express (PCIe) bus. solid state drive), although in theory the PCIe bus protocol is not necessarily required.

NVM stands for the acronym for non-volatile memory, which is a common form of flash memory for solid-state drives (SSDs). This specification mainly provides a low-latency, internal concurrency native interface specification for flash memory-based storage devices. It also provides native storage concurrency support for modern CPUs, computer platforms and related applications, so that host hardware and software can make full use of it. Parallel storage capabilities of solid-state storage devices. Compared with AHCI in the previous mechanical hard disk drive (HDD) era, NVMe/NVMHCI reduces I/O operation waiting time, increases the number of operations at the same time, and has a larger capacity operation queue.

Relying on the PCIe bus, NVMe devices can be applied to various physical slots that support the PCIe bus, including standard size PCIe expansion cards (usually 4 PCIe channels) and U.2 physical connection interfaces (SFF-8639) 2.5-inch/3.5-inch standard size solid-state hard drive, SATA Express bus (compatible with PCIe) devices, M.2 specification expansion cards, etc.

This specification is managed by the "Non-Volatile Memory Host Controller Interface Working Group".
