SSD "healthcheck"?
Is there a program for linux to check the health an SSD drive?
The standard way to do diagnostics for hard drives was always smartctl. I guess the same interface should work for SSD... but I've got no experiences with SSD yet.
SSD Life is a good software, but for Windows only :( As said liori above, you can use any SMART control software and look for attribute value, what corresponds to drive health. For example, for Intel SSDs it's a E9 - media wearout indicator, it's value is a drive health (100 = 100%).
