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.

Sequential Read

The charts are a little different today. Instead of ordering the results from highest to lowest performance, we grouped them by capacity. We have three capacities and three different types of flash.

The Toshiba A19 TLC 480GB drive gave us an odd result. But aside from that one score, the rest of the drives finish where we expect them to.

S10-controlled retail products like the Corsair Neutron XT, Kingston HyperX Savage and Patriot Inferno all deliver exceptional sequential read performance. The three examples lead our charts in this test with more than 560 MB/s, the upper limit of SATA 6Gb/s.

    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.
