Transcend's PCIe SSD 220S aims at high-end applications, such as digital audio/video production, gaming, and enterprise use, which require constant processing of heavy workloads with no system lags or slowdowns of any kind. Utilizing the PCI Express Gen3 x4 interface supported by the latest NVMe standard, 3D NAND flash memory, and a DRAM cache, the PCIe SSD 220S offers supreme transfer speeds that override others. Transcend's PCIe SSD 220S follows NVMe 1.3 and utilizes the PCIe Gen3 x4 interface, meaning four lanes are used for transmitting and receiving data simultaneously, resulting in the compelling performance of up to 3,500MB/s read and 2,700MB/s write.PCIe is a much faster interface than SATA for connecting a host computer to solid-state storage devices over one or more lanes consisting of one transmit and one receive serial interface in each lane, meaning it can better fulfill new performance requirements.NVMe (or NVM Express) is a host controller interface standard designed to address the needs of enterprise and client applications that utilize PCI Express-based solid-state storage. The NVMe calls for better performance vectors than AHCI (Advanced Host Controller Interface), including scalable bandwidth, increased IOPS, and low latency. The SSD220S 2TB comes with 03 years warranty.
