Samsung MLC SSDs promise 20 times improvement in lifespan

Throw a rock in the tech world and it can’t help but hit a few research firms touting the fact that solid state drives (SSDs) will be replacing traditional HDDs in computers of the future. The SSD has some benefits, but for now the price and capacity of the SSD simply rule it out for enterprise and consumer use for the most part.

Samsung announced that its latest SSDs are now in volume production. The new SSDs will be available in 128GB and 64GB capacities. The capacity isn’t what sets these drives apart, rather it’s the multi-level cell (MLC) technology used in the Samsung SSDs.

According to Samsung the new MLC SSDs are capable of providing read speeds of 90MB/s and write speeds of 70MB/s -- performance on par with SSDs using single-level cell technology. The difference is that SSDs built on the MLC technology offer about a 20 times improvement in the typical 4-5 year lifespan of a PC hard drive. Power consumption is another big feature of the MLC SSDs with requirements for 0.2 watts in standby and 0.5 watts in active mode.

Jim Elliott, VP memory marketing for Samsung Semiconductor said in a statement, “With the 64 GB and 128 GB MLC SSDs, we are satisfying the density requirements of most business users and many PC enthusiasts, who will appreciate not only the performance gains and added reliability, but also the more attractive pricing.”

Samsung says that the MLC SSDs will use a 3 Gbps interface and that the 128GB uses 64 MLC NAND flash memory chips of 16 gigabits each and is enclosed in a brushed metallic casing measuring 100mm x 69.8mm and 9.5mm thick. Samsung declined to comment on the pricing of the SSDs.

Samsung first announced the 128GB MLC SSD in January and it is just now entering mass production.
