Phison S10: Toshiba MLC And TLC Versus Micron L95B MLC

By

Phison offered to let us test its S10 controller with three flash types that will ship in 2015: Toshiba's A19 TLC, 15nm MLC and Micron L95B 16nm MLC.

Notebook Battery Life

In our notebook test, the SSDs with TLC flash deliver more battery life than either of the two MLC-based models. The retail drives we've tested that use Phison's S10 all delivered admirable run time. But it looks like TLC will improve this discipline even more.

With the Lenovo T440 running on battery power, all of the drive exhibit similar performance. This is good news for travelers who routinely spend a lot of time away from wall outlets. Since TLC-based drives reduce the cost of SSDs, many of them will end up in business notebooks deployed in Fortune 500 companies.

    whoa, where did you guys get some 4800GB just for the battery life tests?

    Yeah so many typos I almost thought they actually did get 5 terabyte SSDs somehow.

    I was arranging a chart while reading this article to see who actually wins. Seems like Toshiba 15nm MLC wins the test, with Micron 16nm MLC close on tail and TLCs wayyyy off :D.

    It is kinda disappointing to see TLCs being outperformed so brutally. I guess increased SLC buffer should mitigate the problem? Samsung already has like this in the EVO 2TB so what do you think Chris?

    Also, does lithography has anything to do with performance? I mean Micron's NANDs are close to Toshiba's MLCs and Micron's cells are just 1nm bigger than Toshiba's MLCs. Can this be co-related somehow?

    It is so cool that they provided these for a head-to-head comparison. Finally, a comparison with all other variables really held even.
