![]() PCIe 4.0 platforms allow for more flexibility and available bandwidth. Enterprise-class PCIe NVMe SSDs will use all three form factors, with U.2 being the most popular because of its compatibility with server backplanes. Client PCIe NVMe SSDs typically only use the M.2 2280 form factor because its slim design allows it to easily fit into desktop and notebook PCs. PCIe NVMe SSDs can use various form factors such as add-in card (AIC), M.2, and U.2. What form factors are used by PCIe NVMe SSDs? PCIe Gen 4 solves this performance bottleneck, allowing PCIe NVMe SSDs to read and write data at much faster speeds. This was effectively creating a bottleneck in SSD performance. PCIe Gen 3 was unable to accommodate the full bandwidth of high-speed PCIe NVMe SSDs. Does PCIe Gen 4 make PCIe NVMe SSDs faster? As these drives operate on the PCIe bus, they offer vastly improved bandwidth and quicker response times than SATA SSDs. PCIe NVMe SSDs are solid state drives that use the high-speed PCIe bus for data transfer as well as the NVMe (Non-Volatile Memory Express) protocol to communicate with the host system. ![]() Why is PCIe Gen 4 necessary?Īdvancement in PCIe technology is necessary to accommodate the growing need for a high-speed data bus that enables increasingly demanding user applications and workloads. PCIe Gen 4 allows systems to connect to high-performance PCIe devices such as GPUs and PCIe NVMe SSDs. The successor to PCIe Gen 3, PCIe Gen 4 is the fastest PCIe generation available on the market today. PCIe Gen 4 is the fourth and latest generation of the PCI Express specification. But what is PCIe Gen 4? We’ll break down the basics. ![]() Today, PCIe 4.0 has attracted an upsurge of excitement for this technological innovation whether it be SSDs, GPUs, motherboards or high-powered expansion cards. However, we did not see SSDs or graphics cards using the new tech until Computex 2019. The fourth generation of this interface, PCIe 4.0 standard, was announced in 2017. PCIe has been the standard interface for connecting high-speed peripheral components to computer motherboards for the past decade. ![]()
