    While running OCZ's toolbox, I noticed that if you click on SMART DATA, they are nice enough to show you this info:
    I was just curious what other people's stats are so far with their SSDs ?
    This is my main OS drive.

    Purchased 2-10-11
    Power on hours: 48 (obviously wrong)
    Power on cycle count: 240
    Host writes: 778 GB
    Media wearout: 0

    would be helpful if you guys can put when is the purchase date of the ssd.
    so that we can compare the host write with the period of usage.

    :)

    I think indilinx drives must suck.

    My OCZ Onyx 32GB (bought in Nov 2010) is at 74%.
    Both my Intel X25-M G1 80GB drives (one from Apr 2009, one from Nov 2009) are at 95-96% with much heavier use.

    Note that they take the life remaining as ([max rated writes per cell] - [average writes per cell]) / [max rated writes per cell]. The Onyx is rated for 5000 and the writes are piling up quickly, while the Intels are rated for 10k, and seem to accumulate quite slowly.

    Extrapolating these rates, the Intel drives should last well beyond their useful lifetime. I might have to replace the Onyx quite soon; at least OCZ has a 3-year warranty.

    Yeah indilinx drives are known for their extremely high WA rates compared to the newer controllers (indepent of them being Intel, SF or whatever). Although I must say 26% in 6months is bad.

    Although I'd assume after the first setup and tests the used up cycles should slow a bit down and not to forget the max rated writes per cell are often a good bit lower than what the flash really can bear.

    My SSD (OCZSSD3-2VTX90G) was purchased: 2/23/2011
    It died 4-24-2011.
    Yes, *right* after that post. :mad:

    Stupid thing has solid red & green LEDs on, and I guess this means it is dead.
    :thumbsdown:

    Sweet, sweet irony....

    j/k

    Sorry that your drive ate it, hate to say it, but it seems like this is all but standard fare with OCZ drives. I guess Intel or bust.... :-/

    I have serious reservations about the efficacy of the reported metrics. As far as i know a firmware flash resets the data, so with that that in mind, how can it be reliable?

    My Kingston 40GB (re-badged Intel X-25V) is showing 94% life remaining after almost 4 TB of host writes:

    My Intel 80GB X-25M G2 is showing 100% life after about 300GB of host writes:

    That was my understanding as well, but I recently updated my Vertex 2 (from 1.23 I think to 1.33) and host writes and all the other SMART data was not reset. It might depend on the firmware revision and other factors.

    edit: Anyway, here are stats for my two drives.

    I only have experience with the Intel drives, and they do not reset their counters.

    Think of the havoc it would create for IT departments if it did.

    How do I pull up info on a RAID 0 SSD set? CrystalDiskinfo wont work.

    @frostedflakes. smart data is not reset on most controllers unless the flash is destructive in nature.

    @gamefreak. you need to set the bios to ahci and boot from another OS volume to use that or any other app to read smart data from an SSD.

    here's mine on the supposedly crappy OCZ drives. And this figure is for only 1 of my 6 drive array so the read/writes are mutlipled by a factor of 6.

    Replacement arrived, and well...hmm, what would you guys make of this:
    The only thing done to this SSD was to restore the backup image to it. (~40GB of data)
    It takes over 10+ mins to even boot into windows...

    Not sure what is going on with this thing. :confused:

    I know that. I just dont feel like doing it, plus its a new build so there would hardly be anything on it.

    Have to post mine. The drive is my OS drive, it has all my programs and all my documents. The swap file IS on this SSD.

    No, it won't function for 90 years of continuous use (well, it probably wouldn't...) but this means that with 10k writes the media is not going to ever wear out before other parts on the SSD fail (stuff like capacitors and solder joints and so forth). It's real lifespan is probably ~10-20 years, although ofc it is already obsolete today and will not be useful as a drive because it's too small in ~3-5 years.

    Point : media that only lasts for 3k writes is still just fine for most SSDs. If I were an SSD manufacturer, I would make a special warranty exception that would make the warranty last an extra 2 years (5 years total) for SSDs that fail due to media wearout.

    very unlikely due to the fact that none will warrant a drive that has burnt all the nand anyways. If they did then many more would be using these consumer based drives in servers and replacing them under warranty when spent. Who needs SLC then, right?

    I know, but if something allowed me to check it without jumping through hoops would be nice. If you felt I was ragging on you then I'm sorry, that was not how I meant it.

    As it is now, you can do that. The 3 year warranty still applies if you use up all your NAND.

    sure about that? lol Put a small one in a heavy use server and see if Intel will let you get a fresh one when you burn it out. Here's the loosely translated(at least in this case it is) warranty info.

    Intel warrants that hardware Products to be delivered hereunder, if properly used, will be free from defects in material and workmanship
    and will substantially conform to Intel’s publicly available specifications for three (3) year following the date of shipment unless a
    different warranty statement is specified. If any Product as furnished by Intel fails to conform to any warranty, Intel's sole and exclusive
    liability will be, at Intel's option, to repair, replace or credit Buyer's account with an amount equal to the price paid for any such Product
    which fails during the applicable warranty period provided that: (i) Buyer promptly notifies Intel in writing that such Product is defective
    and furnishes an explanation of the deficiency; (ii) such Product is returned to Intel's service facility at Buyer's risk and expense; and
    (iii) Intel is satisfied that claimed deficiencies exist and were not caused by accident, misuse, neglect, alteration, repair, improper
    installation or improper testing. If such Product is defective, transportation charges for the return of Product to Buyer within the USA
    will be paid by Intel. For all other locations, the warranty excludes all costs of shipping, customs clearance and other related

    charges. Intel will have a reasonable time to make repairs or to replace Product or to credit Buyer's account

    The red part is the stuff that will bite you in the ass when you try to beat the big guys by using MLC in an SLC environment and all other mfgrs are the same in that respect. Assumptions will get you no where when Intel's money is on the line. ;)
