With the emergence of NVMe agreement, breakthrough changes have taken place in the performance of the SSD. DIY users based on performance has always been a tireless pursuit, Wei Disk specially introduced NVMe SSD, adopts the PCIe Gen 3.0 four channels, m. 2280 interface, it can be of three times stronger than the general SATA3.0 SSD performance, with lower latency and power consumption control, and higher transmission speed.

NVMe agreement to streamline the invocation style, execute the command does not need to read the register, NVMe standard is geared to the needs of PCI - E SSD, use the primary PCI - E channel directly connected with the CPU can revoke SATA interface with SAS brought by the external controller and CPU communication latency, and NVMe can the maximum queue depth from AHCI cap 32 the ascent to 64000, a sharp rise in the IOPS SSD.

Continuous read speed of up to 2000 MB/s, continuous write speed of up to 1600 MB/s. And adopting new process NAND flash 3 d particles, improve the storage density, different from the 2 d NAND flat configuration, 3 d stereo configuration NAND using vertical way storage unit. At the same time, with the change of the storage unit arrangement, the communication between the chip speed is also becoming more quickly and efficiently. Carrying PCIe Gen 3.0 * 4 channel, theoretical maximum transmission rate can be up to 4 gb/s, compared with the Gen 3.0 * 2 on market channel SSD - theoretical maximum transmission rate is only 2 gb/s, speed beyond the two times.

Small size, body size 80 mm * 22 mm * 3.6 mm, desktop, laptop can use, chemical zedoary technology on PCB, is based on the mainstream on the market on the OSP process upgrading, occupy obvious advantage on the signal integrity and stability. Built-in Power loss detect technology, ensure the SSD continuing to be abnormal Power, strengthen the Power loss data recovery after architecture, to ensure that data is not lost.
