Toshiba announced the first consumer SSDs that utilize its 19 nm-class NAND flash memory. The flash memory innovator released as many as 11 new SSD models, spread across 2.5-inch standard, 2.5-inch 7 mm-thich, and mSATA form-factors, utilizing the 19 nm-class NAND flash memory which it announced in early-April. 

Apart from higher densities (capacities), the new SSDs offer a suite of new technologies that are Windows 8 optimized. These include SATA revision 3.1-compliance (new power-management features); Deterministic Zeroing TRIM, a performance-optimized TRIM garbage-collection mode that will be exclusively available with Windows 8 and future Linux kernels; Quadruple Swing-by Code (QSBC), a performance-optimized error-correction feature; and a read-only mode, which prolongs life offers security on devices such as IPCs. 

Among the 11 models launched, are four each for 2.5-inch standard and 2.5-inch 7 mm-thick form-factors, and three mSATA form-factor models. Apart from physical thickness, the two 2.5-inch lines are identical, and are available in capacities of 64 GB, 128 GB, 256 GB, and 512 GB. The 64 GB variant offers transfer rates as high as 440 MB/s, while the other variants offer transfer-rates up to 524 MB/s. The mSATA line includes 64 GB, 128 GB, and 256 GB variants, with comparable performance to their 2.5-inch cousins. The exact model numbers are tabled below.

Although announced today, Toshiba's new SSDs won't reach the markets before August.
