Toshiba Intros 19nm NAND Flash-based SSDs

[onethreehill]

Toshiba announced the first SSDs based on its swanky new 19 nm-class NAND flash memory. These include four models in the 2.5-inch 9.5 mm-thick form-factor (standard), another four models in the 2.5-inch 7 mm-thick form-factor (slim, for Ultrabooks); and three models in the super-compact mSATA form-factor. The 9.5 mm-thick and 7 mm-thick 2.5-inch models differ only with their thickness, and are otherwise identical, since SSDs are essentially just printed circuit boards with NAND flash memory, controllers, caches, and ancillary components soldered onto them.

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 .......

Bettererer then they're Extremes?! :O

If I remember the issue with smaller structures is that the smaller they are, the faster the cells degenerate and consequently smaller does not necessarily mean better?

smaller is cheaper so they can add in redundant storage for less cost to get over all better lifetime at a lower cost than the last gen. that has been the case every time so far so it should not be a problem atleast for consumers.

True but this ofc fully depends on how fast the cells degenerate. There wil be a point where they need to add so much storage that it makes it more expensive.
