Consensys has confirmed the existence of a "Disk Write Heavy" issue in MetaMask and is preparing to release a fix.

On July 21st, the developer of MetaMask, Consensys, confirmed that it will release an emergency fix for a bug in the browser extension that is causing abnormal disk writes. Several users reported that the plugin was continuously writing data in the background, with a speed of up to 5MB per second, resulting in an average daily write of 500GB on solid-state drives (SSDs). This issue can be traced back to May 9th when user "Quanquan" reported that the unused MetaMask plugin was writing 100GB of data in a single day. On June 24th, user ripper31337 documented this issue, stating that the accumulated write amount over three months reached 25TB. A spokesperson for Consensys acknowledged the existence of "abnormally high disk activity", mainly affecting users with large state data, and promised to address it by reducing the write frequency and optimizing data fetching strategies. However, the latest feedback as of July 17th shows that the vulnerability still persists. Some users claimed that the plugin has already consumed 50% of their SSD's lifespan. The MetaMask team responded again on July 19th, stating that the fix is in progress. (Cointelegraph)
