The latest Windows Operating Systems from Win8.1 up natively do support NVMe.Everything seems to be prepared for a drastical SSD performance boost by the new data transfer standard named NVMe:.The table below summarizes high-level differences between the basic NVMe and AHCI device interfaces: At a high level, the basic advantages of NVMe over AHCI relate to its ability to exploit parallelism in host hardware and software, manifested by differences in depth of command queues, interrupts processing, the number of uncacheable register accesses etc., resulting in various performance improvements.:p.

NVMe has been designed from the ground up, capitalizing on the low latency and parallelism of PCI Express SSDs, and fulfilling the parallelism of contemporary CPUs, platforms and applications. Such an interface has some inherent inefficiencies when applied to SSD devices, which behave much more like DRAM than like spinning media. This is because AHCI was developed back at the time when the purpose of a host bus adapter (HBA) in a system was to connect the CPU/memory subsystem with a much slower storage subsystem based on rotating magnetic media. While Advanced Host Controller Interface (AHCI) interface has the benefit of legacy software compatibility, it does not deliver optimal performance when an SSD is connected via PCI Express bus. “NVM” stands as an acronym for “Non-Volatile Memory”, which is used in SSDs. NVMe is a specification for accessing Solid-State Drives (SSDs), which are attached through the PCI Express (PCIe) bus.I believe I saw someone with a very similar setup who had v5.10 while scouring the web, so I believe there is an update out there somewhere.

Even if a newer version doesn't support RAID from the BIOS, I would still like to update regardless. The main reason I am hoping to update my BIOS is I am wanting support for RAID configurations (currently it shows only IDE and AHCI).

With this being said, I am concerned about trying to flash my BIOS with wrong firmware and was hoping someone more familiar with this could assist. I have an older system made in 2009, and traditional support for my setup is non-existent. I am trying to find the appropriate firmware to update my BIOS to.
