Pseudo SLC (pSLC) USB 3.0 drive Application on Telephony System
pSLC is a special technology to use controller firmware to make MLC NAND act with better reliability as SLC NAND. Due to MLC with 3000 P/E cycle and SLC with 60,000 P/E cycles, there is no solution in between, which has higher P/E cycles and lower cost.
pSLC is a product due to the demand for high reliability to cost ratio. It has half capacity of MLC NAND, but one-third cost of SLC. Besides high P/E ratio, its performance is also much better than regular MLC.
There was a demand from Japanese Telephony system. They asked for higher small files write speed in USB and most regular USB drives cannot meet their demand. We tried USB 2.0 MLC, USB 3.0 MLC and USB 2.0 pSLC and found only USB 3.0 with pSLC can meet their high requirement. Our performance is much superior to our competitors.
UDinfo pSLC is not only designed for USB, but also for SATA, SD/microSD, PATA and PCIe interfaces. Complete product portfolios make our customers have more choices with us.
