More information about the NVMe specification at Visit Integrated Device Technology at www.IDT. The flash controllers also support enterprise-class features, including advanced encryption, data integrity and reliability features. In addition to fully supporting the PCIe Gen3 host interface for maximum throughput, the flash controllers are fully programmable, enabling customers to differentiate their solutions with custom firmware that leverages IDT’s reference firmware. This eliminates the need for OEMs to qualify multiple SSD drivers, facilitating the widespread use of PCIe SSDs and helping bring to market dramatic improvements in storage latency, throughput, power consumption and cost. The goal of the standard is to help enable the broad adoption of PCIe-based SSDs, and to provide a scalable interface that realizes the performance potential of SSD technology now and into the future. The flash controllers are designed to fully comply with the NVMe standard – a standard that defines an optimized register interface, command set, and feature set for PCIe SSDs. IDT’s new flash memory controller family consists of two versions: 16-channel with PCIe x4 Gen 3 ( 89HF16P04AG3) and 32-channel with PCIe x8 Gen 3 ( 89HF32P08AG3). The BIOS updates can now be downloaded from devices provide a standards-based solid-state drive (SSD) solution, enabling storage and server OEMs to overcome latency and throughput bottlenecks inherent to legacy SAS/SATA-based SSD designs. With the latest BIOS, MSI X99/Z97/H97 motherboards can support NVMe devices as primary storage under Windows7 64bit and Windows8.1 64bit and fully support NVMe booting. MSI’s R&D team fine-tuned the BIOS to fully unleash all the power NVMe has to offer while supporting the majority of devices available on the market without any hassle. Intel announced multiple NVMe based SSDs in different form factors during PAX East 2015 The NVM Express technology is independent from the SSD form factor, meaning PCI Express based, M.2 based, SATA based and SATA Express based SSDs are also supported. Other tests also show lower power consumption for devices using NVMe. What exactly can we expect in terms of speed?Īs you can see in the above graph, speeds are almost doubled when working on the NVMe interface. So, NVM Express is introducing lower latency and lower power consumption while at the same time offering increased transfer rates compared to the outdated AHCI controller. Next to that NVMe has been designed to demand less CPU usage, making it a lot more power efficient compared to AHCI. MSI is the world’s first motherboard brand to fully support NVM Express. I don't need to tell you how much speed advantage there can be gained with this new protocol compared to the outdated AHCI. At the same time NVMe has improved impressively as well in the latency department through optimized design and faster, more direct, communication over PCI Express. However, since SSDs are basically multiple memory chips on a small circuit board operating through signals instead of mechanical operations, SSDs are much faster at processing multiple commands and the same time.ĪHCI only delivers 32 commands at the same time while NVMe allows for up to 64.000 commands in a single queue and on top of that allows for an additional 64.000 queues (where AHCI can only process 1 queue). This is more than enough for any mechanical hard disk drive. With AHCI you can only send 32 commands to the drive simultaneously. Compared to the older AHCI (Advanced Host Controller Interface. The formal name of NVMe is the Non-Volatile Memory Host Controller Interface Specification. AHCI was originally developed long before SSDs were even thought of, and was therefore optimized for much slower operating hard disk drives. NVM Express (NVMe), or the Non-Volatile Memory Host Controller Interface Specification, is a device interface specification that was devised to take advantage of the characteristic advantages of. NVMe is a type of software interface used for solid state drives (SSD), and stands for Non-Volatile Memory - Express (Non-Volatile Memory is a common form of flash memory found in SSD). The NVMe protocol is the successor to the common AHCI protocol that is currently in use for most of us with SSDs and HDDs. But what is it exactly and why is it so much faster? Let's take a look. This new technology is called NVM Express, or NVMe for short. However, there is a new technology available which allows for even faster SSD and HDD data transfer. Of course your SSD is already extremely fast when using a MSI Z97 or X99 motherboard.
