Toshiba leads new storage standards: Xfmexpress let SSD become SD

During the FMS 2019 flash Summit, Toshiba officially launched the XFMEXPRESS standard for removing the PCIe NVME storage device, which is popular, can make SSDs into the size of the memory card, while still maintaining high performance. In fact, the single-chip mini SSD in BGA integrated package has been developed for many years, but they are all directly soldered on the substrate, and there is no scalability and upgrade. Toshiba Xfmexpress uses a card set design with a specially designed socket, an overall size of 22.2 × 17.75 × 2.2 mm, wherein the equipment itself 18 × 14 × 1.4 mm, less than 20 × 16 mm PCIe X4 BGA SSD, is also less than M .2230 SSD. Xfmexpress contacts are more than memory cards, supporting PCIe 3.0, PCIe 4.0, can be configured for two or four channels, thus up to PCIe 4.0 x4, with bandwidth up to 8GB / s, and support NVME 1.3, compatible now and future 3D Flash. As for actual performance, there is no specific number, but Toshiba indicates that the higher-end NVME M.2 SSD is expected to reach 3Gb / s. Although Xfmexpress can not be accessed outside of the external access, the plug is convenient, and it needs to open the product shell when replacing, but it is more convenient than M.2 SSD, no tools can be processed. For the cooling problem of small SSD, especially the high fever of PCIe 4.0, Xfmexpress is also prepared, which can withstand high temperatures, metal sockets can assist heat dissipation, and also support external heat sink. Toshiba said XFMEXPRESS can be used in portable notebooks, embedded, Internet of Things, gaming machines, vehicle equipment and other fields. MicroSD, SD memory card has been introduced into the PCIe bus, and the performance is greatly improved. It is straight to SSD. The SSD is narrowing the volume, and it is straight to the memory card.
