Toshiba announces world's 1st 19nm MLC NAND Flash SSDs | Specifications


Toshiba today announced a new solid-state drive series called THNSNF that’s said to be the first built using 19nm NAND flash memory. The drive lineup comprises as many as eleven different models, spread across 9.5mm and  7.0mm height 2.5-inch variants in 64GB,128GB, 256GB and 512GB, as well as smaller mSATA drives for use in thin and light notebooks with capacities of either 64GB,128GB or 256GB.


The THNSNF series employs Toggle MLC (multi-level cell) NAND flash, which is said to deliver faster performance than competing SSDs using synchronous or asynchronous NAND flash. Toshiba claims the 19nm manufacturing process also helps deliver advances in power consumption and performance. The drives are rated for up to 524MB/s sequential read speeds and up to 461MB/s sequential writes.



  Features include SATA revision 3.1-compliance, TRIM support, Toshiba’s Quadruple Swing-by Code (QSBC) error correction technology, as well as power management technologies for greater energy efficiency.
Mass production for the THNSNF series will begin in August 2012.
