Toshiba announces world's first 19nm MLC NAND flash SSDs

By on June 4, 2012, 1:00 PM

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.

Just one year warranty?

I guess that shows how good they are.

Wonder how they will perform under raid 0.

MTBF of 1.5 Million hours, but it only gets a 1 year warranty... 3 years should be the minimum on all SSDs, or stop saying they are going to last 1.5 million hours because the 171 years they claim is no where near the reality of the situation. It just makes you look bad slapping that measly 1 year warranty on the drive.
