Toshiba announced the development of new solid state disks based on 19nm-class NAND flash memory, it includes four 2.5" 9.5mm-thick models, another four 2.5" models with a thickness of just 7mm (for ultrabooks) and three versions with the super-compact mSATA form factor. Availability is slated for August.
The 9.5 mm-thick 2.5-inch models carry the model number scheme THNSNFxxxGBSS (xxx = number of GB capacity), while the 7 mm-thick 2.5-inch models use THNSNFxxxGCSS. Both lines are available in 64 GB, 128 GB, 256 GB, and 512 GB capacities. The 128, 256, and 512 GB models offer transfer rates as high as 524 MB/s, while the 64 GB model offers up to 440 MB/s. Toshiba implemented a new controller that features next-generation Deterministic Zeroing TRIM (a feature exclusive with Windows 8 and future *nix kernels), Quadruple Swing-by Code (QSBC), a performance-optimized ECC-equivalent, and a read-only mode. The mSATA models (model number scheme THNSNFxxxGMCS) offer similar performance to their 2.5-inch cousins, but are available in only three capacity options, 64 GB, 128 GB, and 256 GB. Toshiba will release its new line of SSDs in August.
