    Without making much noise about it, Corsair retrofitted its Neuton GTX line of performance consumer SSDs with 19 nm Toggle-NAND flash chips made by Toshiba. The newer drives' model numbering scheme looks like "CSSD-NxxxGBGTXB-BK," where "B" denotes 19 nm Toggle NAND flash, and "xxx" denotes the capacity (120/240/480 GB). The MTBF on Corsair website appears unchanged, so does the 5-year product warranty, and rated P/E cycle count of 3,000. The Corsair Neutron GTX line of performance SSDs were launched in September 2012, originally with 24 nm toggle-NAND flash.

    that means this a costsaving downgrade even throu it is a smaller nano technology?
    i don't get the point of the article which says it turns to an read only device..

    better than nothing i say right?

    Smaller production node for flash RAM tend to make them less durable. That's the reason for the articles focus on that.

    The Kingston SSD V300 uses Toshiba 19 nm Toggle-NAND Flash.

    Based on the Kingston V300 TBW specs it's P/E cycle rating is 2000.

    Kingston V300 120GB TBW 64TB
    64TB = 2000 x 128GB NAND / 4

    Kingston HyperX 3k 120GB TBW 96TB (3000 p/e cycle rated, 25nm Intel flash)
    96TB = 3000 x 128GB NAND / 4

    4 = Write Amplification Factor
