Low-density SSDs of Samsung Electronics

Samsung Electronics Co. Ltd has begun sampling low-density, higher-performance solid state drives (SSDs) that are only 30 percent of the size of 2.5-inch SSDs and which are said to be highly cost-efficient to manufacture. With the smaller, low-capacity SSDs, Samsung eyes to offer a replacement for existing hard drives used in low-cost PCs. Available in densities of 8-, 16- and 32Gbyte, the multilevel-cell SSDs will be mass-produced next month.

"We've refined our manufacturing techniques and redesigned our low-density SSDs to get what the low-priced PC market is looking for in the way of improved cost, performance and availability," said Jim Elliott, VP of memory marketing, Samsung Semiconductor Inc.

The low-density Samsung SSDs use the same Serial ATA II controller technology being used on Samsung's newly-introduced MLC-based 128Gbyte SSD.

The new MLC-based SSD at 32Gbyte capacity will read data (sequentially) at 90MBps and write it (sequentially) at 70MBpsperformance levels claimed to be much greater than low-density SSDs on the market. The 16Gbyte reads at 90MBps and writes at 45MBps, while the 8Gbyte reads at 90MBps and writes at 25MBps.

Samsung incorporates four individual 16Gbit MLC NAND chips in its 8Gbyte SSD, as well as four dual-die packages and four quad-die packages of 16Gbit NAND for its 16Gbyte and 32Gbyte SSDs respectively. Moreover, by including a 32Mbyte DRAM as the buffer and four-channel system for the new low-density SSDs, these solutions are better suited for high-speed reading environments.

By unit sales, the low-density SSD market is expected to increase annually by 57 percent until 2011, with SSDs for low-priced PCs being the main driver of market demand, said the company.
