Intel has released a new line of 660p Series solid-state drives in the M.2 NVMe version. The drives of this line use 64-layer chips of 3D QLC NAND flash memory, capable of storing 4 bits of data in each cell. The chips were manufactured by IMFlash Technology, a joint venture between Intel and Micron.
Memory chips are supplemented with the SIlicon Motion SMI 2263 controller, which is the result of the evolution of the SMI2262EN chipset. It was transferred to a new production process, became more compact and received support for QLC NAND memory. The controller is equipped with Intel's own firmware.
The new Intel 660p Series solid-state drives are designed as 512 GB, 1 TB and 2 TB models. The low-end model provides a maximum reading speed of 1500 MB / s and a maximum write speed of 1000 MB / s. The number of I / O operations per second when executing random read operations with blocks of 4 KB is declared at the level of 90000, with random write operations – 220,000. The version with 1 TB capacity is a more productive solution. In this case, the maximum read and write speed is 1800 MB / s, and the number of random I / O operations per second for reading / writing is 150000/220000. Finally, the top model also has a read and write speed of 1800 MB / s, but the number of random I / O operations per second for reading and writing is increased to 2,200,000.
New Intel 660p Series M.2 NVMe solid-state drives go on sale shortly at a price of $ 99.99, $ 199.99 and $ 399.99 for models with 512 GB, 1 TB and 2 TB, respectively.
