Robustness of SSDs Under Power Fault

“Test your SSDs or risk massive data loss, researchers warn”(InfoWorld),Companies adopting flash-based SSDs as a cornerstone to the data center storage systems are risking “massive data loss” due to power outages, according to a new study titled “Understanding the Robustness of SSDs Under Power Fault” by researchers from the University of Ohio and HP Labs. In exposing 15 SSDs from five different vendors to power loss, researchers found that 13 suffered such failures as bit corruption, metadata corruption, and total device failure. (snip) The researchers’ conclusion: “SSDs offer the promise of vastly higher performance operation; our results show that they do not provide reliable durability under even the simplest of faults: loss of power."
