Transcend's SSD 220S follows NVMe 1.3 and uses the PCIe Gen3 x4 interface, which means four lanes are used to transmit and receive data simultaneously, resulting in impressive performance of up to 3,500MB/s read and 2 , 800MB/s write.PCIe (or PCI Express) is a much faster interface than SATA (or Serial ATA) for connecting a host computer to solid state storage devices through one or more lanes consisting of a transmit and ONE receive serial interface on each lane, which means it can better meet the new performance requirements.Nvme (or NVM Express) is a standard host controller interface designed to address the needs of enterprise and client applications that use PCI Express-based solid-state storage. Nvme calls for better performance vectors than AHCI (Advanced Host Controller Interface), including scalable bandwidth, IOPS, and low latency.Transcend's PCIe SSD 220S is designed with LDPC (Low Density Parity Check) encoding, a powerful ECC algorithm to keep data safe. Made with high-quality 3D NAND flash chips and PCIe SSD 220S designed dynamic thermal reduction mechanism ensures superior endurance and stability for high-end applications.Transcend's SSD scope is advanced, easy-to-use software that makes it easy to ensure that Transcend's SSD remains healthy and continues to run fast and error-free by determining the health and optimizing drive performance.
