This afternoon, Changjiang storage officially released its titanium brand of consumer grade solid-state disk products. Among them, the high-end pc005 active adopts the PCI 3.0×4 interface, supports nvme 1.3 protocol, and m.2280 form. In terms of capacity, 256gb, 512gb and 1TB are all full capacity designs. The 3D flash memory chip of Yangtze storage’s own xtacking technology is selected. < / P > < p > the so-called xtacking architecture can process peripheral circuits and memory cells on two independent wafers, making NAND have higher I / O interface speed, higher memory density and smaller chip area. In terms of performance, the nominal sequential read speed of the three capacities can reach 3500mb / s, the maximum sequential write speed is 2900mb / S (1TB capacity), the maximum 4K random read speed is 340k IOPs (512gb), and the maximum random write speed is 360K IOPs (1TB). In terms of reliability, the lifetime write capacity of 256gb is 200tbw, 1TB is 640tbw, and the average time between failures is 1.5 million hours, which provides 5-year warranty. < / P > < p > at present, Zhiti Changjiang storage self operated store has been launched in Jingdong. The pre-sale price of 256gb in pc005 is 369 yuan, and the pre-sale price of 512gb is 529 yuan. At present, they can enjoy the activity of 10 yuan to 50 yuan, that is, a discount of 40 yuan. The products will be delivered on September 22. [image] Google secretly tests 6GHz networks in 17 states of the United States
