    Interesting, the drive locked up again, so I secure erased it this time. Now smart reports:

    sandisk bad.PNG

    Never seen a sandforce drive resist outright panic locking, and never seen 0% from a sandforce drive in SMART before.

    And no, the drive is not readonly, but so far, no data loss either.

    Yeah, but the Plexty wrote 20,000GB a day... That's nearly 190PE cycles a day. If it was doing 70MB/s instead of 270MB/s, it would have gone a lot further.

    Ok, I've been a bit caught up building my hackintosh over the last couple of days, so I need to report the death of the old sandisk 120gig

    It locked up again, but never recovered:

    Final Stats:

    Hours: 2332 (97 days)

    Host GB written (F1): 1,006,659 GiB (983.07 TiB)
    NAND writes (E9): 751,782 GiB (734.16 TiB)

    Retired Block Count (05): 4 raw
    Failure count (AB, AC): 1 program, 1 erase
    Raw Error Rate (01): 120 normalized
    Media Wearout Indicator (E7): 0 normalized (failed)
    Wear Range Delta (B1): 4 raw
    Reported Uncorrectable Errors (BB): 0 raw

    So that is it ... the sandisk lived and died in much to same way as the corsiar force 3 did ... so 24nm Samsung NAND seems about as good as 25nm Micron NAND.

    Bit of a fail that it didn't reach 1PiB written, oh well.

    For now, I won't be endurance testing any drives ... maybe when 19nm NAND is more common.

    RIP sandisk.

    At least it was over the specified PE/count.

    By the way, how can it be possible for the Chronos Deluxe to stay at 350$ for the 480GB?
    Isn't it supposed to contains high priced 32nm Toggle-mode flash?

    The new Chronos Deluxe with a 'DX' in the model number doesn't use 32nm toggle. They are sorta pulling an Ocz...keeping the same model name from a previously fast drive for a newer drive with newer hardware and slower speeds. You can probably expect the faster 'old' chronos deluxe to start disappearing before long or IF they sell enuff of them, they'll keep 'em around like Ocz did with the V3 MaxIOPs line but stay with the premium price ofc.

    There are a couple excellent drives coming out soon that I'm looking forward to, so maybe one of those will become fodder for testing.

    The 512/480 Mushkin is using IMFT, which is probably a good thing. The 2281s with 32nm Toggle are nothing to write home about (at 480GB). With the 2282, that changes I think.

    Depending on the controller, Secure erase doesn't erase the nand either.

    FINALLY!!!

    A new erase failure!!

    It's been over 2PiB since the last. It might have been more like 3PB since the last failure. I hope they start occurring with more frequency; the 830 is really boring me to death. It's like it doesn't even care that it's writing most of the time.

    can you expand on that a bit? i know that SE involves a different voltage being applied to the nand to clear it, but i assumed that would erase it as well. I have heard elsewhere that isnt always the case, but not an explanation of how it works.

    -------------------
    There was another block failure, except this time I think it's a read failure. There are smart attributes for erase and program failures, but not read failures. 11 total reallocation events were comprised of 10 erase failures, 0 program, leaving the remaining one which occured today a read failure based on process of elimination.

    Next test should be done on the Samsung 840 TLC!

    I'll admit, I'm interested in checking it out. I almost can't believe they're using TLC, but what the hell? I'm game. I thought my 830 might have been spiraling downward, but it looks like it won't be dead any time soon.

    +1 for the Samsung 840 with TLC. I got more than enough drives to test at the moment so I've to wait out with that one.
