A SMART tool should base the number on the 73 TB not on the 2 PB ie at 73 TBW it would show 100% used and 2,739.7% when it finally died. Samsung 840 PRO was warranted for 5 years or 73 TB TBW depending on what came first and yet it lasted into the 2 PB range. Take the 256GB Samsung 850 PRO used in the 2015 test for example. However, it’s important to realize what it means to reach 100 percent of projected lifetime – it does not mean that the drive is going to fail when that counter rolls over to 101 percent, only that your SSD may need to be replaced soon." When the SSD is brand new, Attribute 202 will report “0”, and when its specified lifetime has been reached, it will show “100,” reporting that 100 percent of the lifetime has been used. It is a measure of how much of the drive’s projected lifetime has been used at any point in time. This attribute is exactly as its name implies. In fact, very early in this whole thing it came out that the tool being used was using an old reference file which was causing it to cough up nonsensical data.Īlso you missed the point I was making: "The lifetime number is supposed to be what the SSD is warranted for not its total lifespan and there there is no 256GB SSD on the flipping planet what by the numbers has a 5.2 PB warranty." Tl dr: looks OK, check the link at the start of the post if you're interested.Click to expand.Sure the numbers can "lie". As the other commenter recommended, you should change value display to 10. It's usually better to just look at the raw values though. So everything looks OK.Ĭurrent, Worst, and Threshold are sort of like scores, the higher they are, the better that parameter is. In your case all of these values are 0, meaning no such critical errors have been encountered. These parameters are early failure warnings for HDD corruption (reallocation of bad sectors), or mechanical problems (heads having to retry spin). In your case,Īre the critical parameters you are able to view. Most parameters basically just collect benign diagnostic information however the ones listed as "critical" in the link are important to watch. As well as information on if it should be high/low etc. You can get information on what each parameter represents here.
