Contradicting Google’s joint study, Facebook found that higher data write and read rates can significantly impact the lifespan of a drive…though it isn’t clear if the latter was controlling for the physical age of the drive itself. But the study also found that if an SSD doesn’t fail after its first major detectable errors, then it’s likely to last far longer than overly cautious software diagnostic software. The findings were focused on the environmental conditions of the data centers themselves-for example, they came to the fairly obvious conclusion that extended proximity to high heat was damaging to an SSD’s lifespan. For example, if a 250GB Samsung 840 MLC drive failed at 900 TBW, it would be reasonable to expect a 1TB drive to last for considerably longer, if not necessarily all the way to a massive 3.6 petabytes written.įacebook publicly published an internal study (PDF link) of the lifespan of SSDs used in its corporate data centers. Larger capacity SSDs, due to having more available sectors and more “room” to use before failing, should last longer in a predictable manner. Conclusion: a ~250GB SSD can be expected to die sometime before one petabyte written-though two (or perhaps three) of the models exceeded that mark, it would be wise to plan a contingency in case your specific drive under-performs, even if it uses more expensive SLC memory. Two of the failed drives, Samsung and Intel, used the cheaper MLC standard, while the Kingston drive is actually the same model as the one that survived, only tested with a similar methodology. The other drives failed at between 700 and 900 TBW. Among six brands of SSDs tested, only the Kingston, Samsung, and Corsair high-end drives managed to survive after writing over 1000 terabytes of data (one petabyte). The Tech Report’s study on longevity between major brands. Older SSDs are more prone to total failure regardless of TBW or DWPD. Conclusion: in a high-stress, fast-read environment, SSDs will last longer than hard drives, but be more susceptible to non-catastrophic data errors. But it wasn’t all positive in favor of SSDs: they experienced higher uncorrectable errors and bad blocks at a much higher rate than hard drives over the four-year testing period. It also determined that SSD drives were replaced at Google data centers far less often than conventional hard drives, at about a one to four ratio. The study concluded that the physical age of the SSD, rather than the amount or frequency of data written, is the prime determiner in probability of data retention errors. A few of the more well-known ones include:Ī joint study between Google and the University of Toronto covering drive failure rates on data servers. There have been several recent studies trying to determine a more precise lifespan for solid state memory. Tests on industrial data servers, like the ones used by Google and Facebook, give us insight into SSD longevity. We can only give a very vague point of maximum possible data retention, after which using the drive will put you in danger of immediate loss of data and computer operation. And the very fact that there are three extremely loose standards for “wear” on a digital component should illustrate something to the end user: accurately predicting how long it will take a specific SSD to fail is more or less impossible. Obviously measuring by these three different standards will return different results based on methodology. SSD vendors tend to rate the reliability of their drives on three factors: standard age (like any warranty), total terabytes written over time, and the amount of data written to the drive per specific amount of time, like a day. ![]()
