    It sure looks like that. I didn't think about it when I posted the screenshots. The firmware updated failed and SSDLife shows v 0002 so I don't know what happend.

    This is the SSD endurance test, not the USB-Stick endurance test, anyways, there is no way to test USB drives using my software, it disables USB drives and there is generally no way of reading SMART from such drives. (so, no reporting)

    Yes but I am sure that we could just see how long the USB will last because we will know how much TB we write to it without complicated SMART parameters etc.

    The Kingston dropped out again so I got the log fixed with help from Anvil and startet up the test again. I'll post tomorrow because the test had only gone for a couple og hour last night before it dropped.

    The Kingston dropped out again during the night. I'm going to halt the test until I'v found out what causes this problem. It could be the MB starting to protest after 2 months of torture, but I don't know.

    Next update from me will be monday.

    Is SSDLife Data monitor using GB as it is labelled, or is it really GiB?
    I'm assuming GiB as GB doesn't add up.
    Can someone confirm what is correct?

    It is probably using GiB as that is what Windows uses by default etc.

    It is GiB. It converts the sector count SMART readout, which are 512 bytes.

    Host Writes So Far

    Sept8HostBar.png

    Sept8HostLine.png


    Normalized Writes So Far
    The SSDs are not all the same size, these charts normalize for available NAND capacity.

    Sept8NormBar.png

    Sept8NormLime.png


    Write Days So Far
    Not all SSDs write at the same speed, these charts factor out write speeds and look at endurance as a function of time.

    Sept8WDBar.png

    Sept8WDLine.png


    Host Writes vs. NAND Writes and Write Amplication
    Based on reported or calculated NAND cycles from wear SMART values divided by total writes.

    Thank you all for doing this for the community. Are the Intel's still in the running? I'm excited how close all these SSDs are getting towards 1PiB before crapping out!

    MAJOR UPDATE:

    12 hours ago the reallocated sector count was at 105 and reserve space was at 99%.

    Now, my reallocated sector count is at 4071!!! and reserve space is at 27%. This SSD has hours left.... EXTREMELY sudden failure. I am at 395.7TB right now.

    holy cow more excitement! Seriously i cant believe the intel is going out this quickly...even though the normalized charts show it further than the others...noting that it outlasted the 34nm drive though when normalization of capacity is taken into consideration

    how is it, that these drives last so much, when theoretically 25nm SSD should die after 3000 rewrites + some reserve.... ?

    So now I am just waiting for the results of :

    M4 vs C300

    and

    X25-V vs Intel 320

    so we can see how good ( or bad ) 25nm really is.

    The 25nm NAND in the Intel 320 has a minimum P/E cycle rating of 5000. We really don't know what the average/typical/expected lifetime rating is, just minimum.
