Difference between SDSSDA-120G-G25 and SDSSDA-120G-G26 ...?

Hi Guys,

Sandisk seems to have released a newer version of the SSD Plus called G26.

in Europe I came across G25 with Z220 and U210 firmware.

Has the NAND controller evolved, with a newer firmware, like in the US ?

Are these still MLC chips?

Thanks for your answer.

Hi Bolc,

-G25 or -G26 or -1022 or anything after the capacity code is a marketing code, the product inside is the same, this code is for marketing reasons.

Many ecommerce website state that the new version contains TLC CHIP.To fasten the ssd,they replaced the old MLC chip.

New version is no longer MLC.

New version(G26)=NAND: TLC Toggle (15nm, Toshiba)
Older version(G25)=NAND: MLC Toggle (19nm, Toshiba)
I think to speed up the sandisk drives,They changed the NAND to TLC.

Hi Nirmal_Mandal, 

It is not as clear cut as that, both -G25 and -G26 include multiple builds.
