I'm running SC7.5, and can run the test script on two systems that have 60 Gigs Spinning media drive, and 80 Gigs SSD.
Both tests return a "Passed" result, but I can't figure out which tests are used to determine that the SSD is healthy, for example, a spinning media's Linear Seek test is not applicable to an SSD, since it doesn't use "heads", so what is SC7.5 doing when I ask it to run a "Linear seek test" on this SSD? A more appropriate test would be a "Nibble Move test", yet, this is not available for SSDs, how can I make sure the drives are actually being tested properly?

Victor_Lopez,

You are correct, we can't spin up/down the media or do a track to track seek but the SSD drive must still support these features or it would not be a plug and play replacement.  If it did not respond to a spin down command (even though it does nothing), things like sleep would not work.  As I said in your previous post. SSD drives are designed to be a direct replacement for spinning drives.  They need to present themselves to the system as identical or their value would be diminished.   

When you ask SC7 to do a track to track, linear seek or any other drive test on a SSD drive these commands translate into the appropriate SSD test in the drive firmware.  A linear seek test will test all the "memory" on these devices. The memory is organized into virtual tracks and sectors so it can be accessed that way.

Victor,

No worries,  They were a little different so I thought this one deserved an answer also.
