SMART Variables for Sandisk Ultra II

Hello Everyone,

I’m using my Sandisk Ultra II in a Synology DiskStation.

I understand ID 230 is for the Media Wearout Indicator … however, when I view the raw value it is a large number (520101632). How do I convert the value to a percentage?

Also, does anyone have the Smart Variables for Gigabytes written to the disk -  is it 241 and 233?


Media Wearout Indicator is a calculated value from multiple attribute, and unfortunately SanDisk does not share the algorithm for it. 

233 is NAND GB Written,

241 is Total GB Write. 

For your application I think you need to look at 241
