ZHITA, a sub-brand of China's top memory chipmaker Yangtze Memory, released two SSDs for the first time on September 10. Among the new products, one is the PC005 Active drive with PCIe technology and the other is the SC001 Active drive with SATA interface.
The higher-end PC005 Active uses a PCIe 3.0x4 interface and supports the NVMe 1.3 protocol.
It offers 256GB, 512GB, and 1TB capacity options, and the chip is selected from 3D flash memory from Yangtze Memory with Xtacking technology.
The so-called Xtacking architecture, which allows peripheral circuits and memory cells to be processed on two separate wafers, enables NAND to have higher I/O interface speeds, higher storage densities, and a smaller chip area.
It offers sequential read speeds of up to 3,500MB/s and sequential write speeds of up to 2,900MB/s (1TB version). It has 4K random read speeds of up to 340K IOPS (512GB) and random write speeds of up to 360K IOPS (1TB).
As for reliability, the 256GB version has a lifetime write capacity of 200TBW and 640TBW for the 1TB version, with an average failure-free time of 1.5 million hours, both backed by a 5-year warranty.
Currently, the ZHITAI official flagship store has been online at JD.com, PC005 in 256GB pre-sale price of RMB 369 yuan ($54), 512GB pre-sale price of RMB 529 yuan. It is currently offering a 40 RMB discount and will start shipping on September 22.
SATA channel SSD hard drive is still the mainstream of high-capacity hard drives, and the SC001 Active hard drive provides 256GB, 512GB and up to 1TB capacities, 2.5 inch and M.2 2280 specifications are available.
The read speed of the SC001 Active drive is up to 520MB/s and the write speed is 510MB/s, basically reaching the limit of the SATA 6Gbps interface.
In terms of random performance, the 4K random read of the SC001 Active drive is 80K IOPS, random write is 70K IOPS.
The SC001 Active drive can have a sleep power consumption as low as 7mW, an operating temperature of 0-70 degrees Celsius, and a three-year warranty.
The SC001 Active drive uses the original 3D flash memory from Yangtze Memory, based on the Xtacking stack architecture, which offers five times the storage density of the industry level.
Its IO interface speed of 800Mbps is twice as fast as the industry, and it has a P/E life of up to 3,000 cycles.
For the SC001 Active drive, the write life is 170TBW for 256GB, 340TBW for 512GB, and up to 680TBW for the 1TB version.
The 1TB capacity of 680TBW is higher than that of other brands, while the 1TB version of other manufacturers can only achieve 400-600TBW, and the highest level of the SC001 Active drive is about 10% higher than the others.
As a nascent brand, ZHITAI Technology has a marketing direction that focuses on original quality and another that focuses on longevity/reliability.
The SC001 Active drive and PC005 Active are now available for pre-order, with the 1TB version priced at 839 yuan ($122).
