Being more than a decade old, AHCI was designed for hard drives and is therefore optimized for high latency rotating disks rather than low latency non-volatile storage.ĪHCI isn't the best interface for PCIe SSDs and thus industry leaders including Intel, Samsung, and LSI have developed NVMe with advantages such as multiple queues, higher queue depths and lower latency as NVMe allows for a direct path from the storage to the CPU. In addition to the M2 socket, the Non-Volatile Memory Express or NVMe, is a new performance controller interface set to replace the aging AHCI standard. All this changed with Skylake as the Z170 can support twenty PCIe 3.0 lanes through the chipset, so putting aside four of those lanes for an M.2 socket is no longer an issue. The Z97 chipset, which first introduced the M.2 slot on the desktop, only supports up to eight PCIe 2.0 lanes with the rest of the PCIe lanes being used by graphics cards. The Z97 chipset provided support for the M.2 and SATA Express interfaces, both of which were designed to take mainstream SSD performance to the next level. Most are still bound by the bandwidth limitation imposed by the SATA 6Gb/s interface, with the top performing Samsung's SSD 850 Pro offering sequential read and write speeds of 550 to 520MB/s.Ī solution to this problem was revealed midway through 2014 with Intel's Haswell refresh. ![]() We have reached the point where it is possible to buy high capacity SSDs at a reasonable price. M.2 SSD Interface Starting to Gain Traction It is designed to power devices like IoT gateways or sensors and that are designed to run a single application enabling specific industry scenarios and extending the flexibility of Windows 10 offerings to a yet wider range of specialized devices. Windows 10 IoT Core is optimized for smaller and lower cost industry devices. Windows 10 IoT Mobile Enterprise provides a secure device experience, instantaneous application access, and excellent battery life to enable a variety of mobile scenarios.Īll Windows 10 apps are compatible with Windows 10 IoT Mobile and offer advanced lockdown features and multi-user support. Windows 10 IoT Enterprise devices run powerful line-of-business applications and perform specialized functions in a secure, reliable, and streamlined way. Windows 10 IoT Enterprise is a full version of Windows 10 with advanced lockdown capabilities to enable industry specific device scenarios. ![]() Windows 10 IoT is the family name for the Windows 10 operating systems that run on a wide range of devices - from small intelligent devices to industry machinery.
