Samsung Electronics on Monday announced its new lineup of high-performance solid-state drives designed for use in personal computers. The new SSDs are the industry's first drives to use triple-level cell (TLC) and multi-level cell (MLC) NAND flash memory produced using 21nm process technology.


Samsung 840-series SSDs will be available in 128GB, 256GB and 512GB capacities and will be based on TLC NAND flash memory with Toggle DDR interface as well as Samsung's proprietary MDX controller. The more advanced Samsung 840 Pro-series will be available in 64GB, 128GB, 256GB and 512GB capacities and will utilize MLC NAND flash memory with toggle DDR 2.0 interface as well as the same MDX controller. The former family of SSDs will be aimed at regular consumers interested in lower-priced SSDs, while the latter family is targeted at the so-called prosumers looking forward maximum performance and reliability.

The Seoul, South Korea-based manufacturer claims that the new Samsung MDX controller delivers superior performance, high reliability and sustainability that are among the product's proprietary features. The premium class Samsung 840 Pro SSD provides 100 000 input/output operations per second (IOPS) for random read and 90 000 IOPS for random write.

Unfortunately, Samsung was not too specific about other performance characteristics of the new 840-series and 840 Pro-series SSDs. It is especially interesting how the new Samsung MDX controller works with TLC NAND flash memory and how fast and reliable are the industry's first SSDs to utilize this type of memory.

"Introduction of Samsung's 840 SSD series delivers considerable levels of advancements to the notebook user environment. As a technology pioneer, Samsung continues to raise the level of performance of SSDs and contribute to the growing global pool of users enjoying the conveniences of high-performance SSDs," said UnSoo Kim, vice president of memory brand product marketing team at Samsung Electronics.

The new 840 series will be available globally from mid October through retail channels.
