Toshiba introduced on Monday an upcoming line of SSDs claiming to be the "world's first" to take advantage of 19-nm process NAND flash memory, the THNSNF series. Even more, the series will use Toggle MLC NAND flash which should provide faster performance than competing SSDs using synchronous or asynchronous NAND Flash.
"Our customers are increasingly looking to SSDs as a storage solution across multiple products and markets because of the performance and reliability they deliver," said Joel Hagberg, vice president of marketing at Toshiba’s Storage Products Business Unit. "The THNSNF series provides not only great performance, but also extremely low power consumption across a broad range of form factors and capacities."
Clocking in at around twice the speed of Toshiba’s HG3 series SSDs, the THNSNF series will deliver efficient power utilization of less than 0.1 W, exceeding the Business Applications Performance Corporation MobileMark 2007 benchmark for battery life. Consumers will also have peace of mind knowing the key components -- from firmware to NAND to controllers -- are designed by Toshiba instead of imported from 3rd party suppliers.
On a technical level, the SDDS will have a max sequential read speed of up to 524 MB/s and a max sequential write speed of up to 461 MB/s. They'll also have a random 4KiB IOPS sustained read of 80k (save for 64 GB version which will be 50k), and a random 4KiB IOPS sustained write of 35K (save for the 64 GB version which will be 25K). They'll connect via a SATA 3 interface and have a MTTF of 1.5M hours.
Toshiba said the new THNSNF series will go into mass production in August 2012, and include data protection through use of Quadruple Swing-By Code (QSBCT), Toshiba’s error correction code technology. Four capacities will be offered -- 64 GB, 128 GB, 256 GB and 512 GB -- and the three following form factors:
THNSNFxxxGBSS -- 9.5 mm height, SATA 6 Gb/s
THNSNFxxxGCSS -- 7.0-mm height, SATA 6 Gb/s
THNSNFxxxGMCS -- mSATAT, SATA 6 Gb/s
