First industrial-grade PCIe 4.0 SSDs
5G and AIoT need more speed and more capacity, and PCIe 4.0 delivers, doubling the speed of PCIe 3.0 and providing the much-needed performance boost to keep pace with innovation and industry trends.

PCIe 4.0 provides the much needed speed and capacity for 5G and AIoT applications, doubling the speed of PCIe 3.0. However, not only speed and capacity, but tolerance of wide-range temperature is also crucial. Consumer-grade products aren’t tough enough to withstand the high temperatures of outdoor and industrial settings, so Innodisk is introducing the first industrial-grade PCIe 4.0 SSDs built to handle those challenging conditions.

PCIe 4.0 increases the maximum capacity to 4TB, doubles the bandwidth, and raises the speed to 16 GT/s, which is twice that of PCIe Gen3. Although third-generation PCIe offered only modest speed increases over the popular SATA III for storage applications, it did provide the much sought-after advantages of full forward and backward compatibility. PCIe 4.0 retains that coveted compatibility while also adding noticeable speed increases.

The recently announced industrial-grade PCIe Gen4x4 NVMe SSD series features 112-layer 3D TLC technology, offers temperature tolerance from -40 to 85°C, supports AES-256 encryption, and is compliant with TCG OPAL 2.0. This new series also utilizes NVMe technology that provides a necessary performance boost and other technological advancements encompassed in NVMe. One notable innovation is Namespace technology, which delivers better read and write efficiency and a longer SSD lifetime.
