I did a quick search in this section of the forums and on Google for the Longterm Data Endurance (LDE) of the Sandisk Extreme 120gb SSD drive, I did not come up with any hard answers. The closest I came was a piece of text in my Google search results for the Sandisk Ultra drives, stating that they could have 60 terabytes written before performance was affected. What can I expect with the Sandisk Extreme 120gb drive?
I have two 120gb Extreme’s in a raid 0 config with about 1TB of data written on each drive. I have tried to use the SSD-Life lite tool but because of my raid array it does not detect the SSD’s. Would it be possible to find a Linux tool that does the same as ssd-life, turn raid off in my bios, boot to a live CD/USB, examine the ssd drives, then change the bios back and have everything back to normal? I did break the array when I upgraded the firmware for the drives and when I was done put the settings back and windows booted normal, but I think trying to do that for this may not be that easy.
Basically I am trying to figure out how much life I can get out of these drives before I see a performance drop.
Also, I did see the MTBF for the 120gb rated at 2.5 million hours. How is this different then the LDE? Also 2.5 million hours is 285.199 years, how do they come up with such numbers??
