How does TrueImage 2011 handle HD to SSD unused but dirty blocks
As we all know already: when deleting a file on an HD windows will only update the filesystem tables - it won't zero the blocks
I understand ATI to be a "file-system aware block-level backup" application
So when migrating a volume to an SSD (with TRIM) is ATI smart enough not to copy the dirty unused blocks?
If not:
a) the restore process will be slower
b) it will wear the ssd more
c) it will slow down writes to the unused dirty blocks (because they are not trimmed)

FireDragon,
ATI will leave it to the SSD controller to do the right things.
a) ATI writes to the SSD pretty much as the same level as the OS,
b) not exactly true. Each SSD controller has its wear-leveling logic and memory cache/buffer algorithm to handle OS-level writes.
c) like the OS, ATI is not aware of the unused dirty blocks, but the controller is. The TRIM function works with the OS-level drivers.
