错怪微软？SSD掉盘原因被找到了！

Core Viewpoint - The article discusses the issue of SSDs being formatted to RAW after Windows 11 updates, identifying that affected SSDs were using engineering firmware rather than official firmware [2][7]. Group 1: SSD Issues and Testing - The SSDs tested included Corsair MP600 2TB, SP US70 2TB, and Apacer AS2280F4 2TB, with issues such as drive dropouts and performance degradation during stress tests [4]. - The problems were replicated during a 100GB file stress test, with specific models experiencing drive dropouts and crashes, while others showed speed degradation [4][6]. - Initial tests by the manufacturer, Phison, did not replicate the issues, leading to further investigation [5][6]. Group 2: Firmware Investigation - The investigation revealed that the problematic SSDs were using engineering firmware, which is not intended for consumer use, while the same models with official firmware did not exhibit issues [7]. - It is suggested that users experiencing these problems likely purchased SSDs through non-standard retail channels, such as second-hand markets [7]. Group 3: Performance Degradation Explanation - The Apacer AS2280F4's performance drop was attributed to its SLC cache being filled, leading to slower speeds during heavy write operations [8]. - SSDs utilize mechanisms like Over-Provisioning and Garbage Collection to maintain performance, which can be affected when data storage exceeds 50% capacity [9]. - Windows formatting does not fully erase data, and users experiencing slow write speeds are advised to use dedicated SSD erasure tools for better performance recovery [9]. Group 4: Broader Implications - The article hints that the issue may not be limited to Phison controllers, suggesting that if other controllers are affected, Microsoft may share some responsibility due to potential bugs triggered by their updates [10].
