搜了一段,不知都能不能缓解一下焦虑的心情 Why are the E2 and E4 SMART attributes reporting large numbers? Generally, these attributes are only used in specific test environments. The definition for SMART attributes E2 (Timed Workload Media Wear) and E4 (Timed Workload Timer) can be found in the product specification. These attributes are not used to indicate long-term SSD health or performance.
E2: Timed Workload Media Wear Raw value: measures the wear seen by the SSD (since reset of the workload timer, attribute E4h), as a percentage of the maximum rated cycles. Divide the raw value by 1024 to derive the percentage with 3 decimal points. Normalized value: always 100.
AA和E8 致命 Available Reserved Space Raw value: reports number of reserve blocks remaining. Normalized value: begins at 100 , which corresponds to 100 percent availability of the reserved space. The threshold value for this attribute is 10 percent availability.
