That gives companies such as SanDisk an edge in this market because they control both the SSD and Flash memory technology, he said.
"Hard drive vendors don't have the Flash technology," he said. "They can make deals with Flash manufacturers, but they don't own the technology. Without the roadmap to look at the crosstalk between cells, it's hard for them to keep up with the technology."
SanDisk looked at the different SSD vendors and decided to acquire Pliant because of that company's ability to take MLC-based NAND Flash memory to compete in an industry where SLC NAND, with its higher performance, had been expected to drive the enterprise SSD market, Sadana said.
"SLC is much more expensive than MLC," he said. "But Pliant has been able to get extremely good performance with its enterprise MLC products. In addition, Pliant has an ASIC-based solution for its SSD controller which many of its competitors use FPGA-based controllers which are larger and more power-hungry."
