SSD Kingston SA400S37120G, Firmware Version: SBFK61K1
smartmontools (linux, latest version via distro software manager)
reports SMART Attribute 231 (SSD_Life_Left) as a raw value of 100 and normalized/worst/threshold values of 0. Is this possible?
ID# ATTRIBUTE_NAME FLAGS VALUE WORST THRESH FAIL RAW_VALUE
231 SSD_Life_Left ------ 000 000 000 - 100
Other Attributes seem fine.
The drive has only been in service for a couple of months with light usage (Power_On_Hours Raw=171).
With the definition in a 2015 document https://media.kingston.com/support/downloads/MKP_306_SMART_attribute.pdf
- Normalized Value Range: 100 = Best = Full SSD life remains, 1 = Worst = Insufficient Flash blocks remain in service for proper SSD operation
- Raw Usage: [0]: 0 = Life driven by PE cycles, 1 = Life driven by Spare Blocks, [6-1]: None (0x00)
would expect output more like VALUE:99, RAW_VALUE=000
(a Kingston rep mentioned as soon as a drive is connected it's reduced to 99)
Thanks.
