На что обращать внимание при оценке здоровья SSD диска
Для нормального состояния диска у каждого производителя данные отличаются.
- Для большинства дисков по столбцу RAW_VALUE должны быть значения 0 у параметров:
- 01 Raw Read Error Rate;
- 05 Reallocated Sectors Count;
- 196 Reallocation Event Count;
- 197 Current Pending Sector Count;
- 198 Uncorrectable Sector Count;
- 199 UDMA_CRC_Erro;
- 250 Read Error Retry Rate.
- Также по столбцу VALUE (не RAW_VALUE), значения должны быть больше 1:
- 233 Media_Wearout_Indicator;
- 231 SSD Life Remaining;
- 170 Available_Reservd_Space (больше 10).
