They come in both the 2.5-inch and mSATA form factors

Toshiba has finally used its new error correcting technology in a collection of solid-state drives, and it even went all the way and used its most advanced manufacturing technology.

By “most advanced manufacturing technology” we mean the 19nm production node. The new SSDs may not be the first to use the process, but the ones that did come first were Toshiba's as well.

That said, there are two distinct lines of new Toshiba 19nm NAND SSDs, though they are marketed as part of the same family: THNSNH.

On the one hand, we have the 2.5-inch drives in 60 GB, 128 GB, 256 GB and 512 GB (they have both 7.0 mm and 9.5 mm profile variations).

On the other, we find the mSATA modules in 60 GB, 128 GB and 256 GB.

Obviously, the former set is good for desktop PCs and normal-size high-end notebooks, while the latter drives are better suited to ultrabooks, being so much smaller and thinner.

In every instance, the SATA 6.0 Gbps interface is used (SATA III), leading to a performance of up to 534 MB/s when reading and 510 MB/s when writing.

The read/write speeds vary according to capacity though. The 60 GB drives, for example, are limited to 450 MB/s and 430 MB/s, respectively.

The mSATA 128 GB and 256 GB SSDs work at 471 MB/s and 450 MB/s, the same as the 2.5-inch 128 GB units.

The 2.5-inch 256 GB drives go a bit higher, to 482 MB/s and 460 MB/s. For that matter, the 512 GB drives usually stick to these upper limits too, even if the theoretical maximums are what we wrote above.

Sadly, Toshiba did not provide pricing or availability details for its newest data storage devices. Then again, they are mostly mobile PC components, so that information is probably going to be released on a need to know basis, whenever a brand orders a batch for its newest notebook configurations.
