    Anvil,

    I'm getting weird display on endurance testing:

    This is the problem right here. I have 8 x 2tb consumer drives at home. I bet if I ran a several disk test on these when I get home I wouldn't get a data read error. Given the reasoning in this...

    I'm not running any endurance test. However, your drive is showing, using that current smart command, far more wear than expected for a 250gig drive that has only done 6TB of writes

    I can understand "smartctl -a /dev/sda" better.

    -a will give unmolested statistics from the drive's smart function.

    Having software molest the data tends to lose some of the information.

    Programs like fancy cache are a bit of a fail IMO.

    I have done it a few times to get more space in a single volume, but at a lower price.

    512gig drives can be very expensive, but are now coming down in price.

    Look at how my vertex 4 tests went ... a vector would behave quite similarly (but not as strongly as the 120gig version of course)

    It is only one factor. The Samsung 840, at it's current price, is just not competitive. There is no compelling reason to buy a TLC based drive for the same price as a MLC based drive.

    You are right, It died about 5 hours ago.

    Not a terrible result out of this drive at all, but I wouldn't buy it unless it is cheaper than the alternatives (which it isn't at the moment)

    Try it outside of a virtual environment.

    Even the linux console in ESXi is a virtual machine, so it will have the same kinds of overheads as any other virtual machine.
