Windows defrags ssds once a month ....with the new technology of ssds ....defragging once a month does nothing but keep the life of the ssd. Please do some research on ssds and windows. The only bug is that windows defrag wont retain the defrag history. You should set auto defrag to once a month is you have an ssd. Manual maintenance is in case of need to.
According to Scott Hanselman of Microsoft, Windows 7 and later do defragment a solid-state disk (SSD) but in a completely different way. There is less incentive for defragmentation of SSDs because file fragmentation has less performance impact on them and they handle a finite number of storage cycles before their lifespan expires. However, file systems cannot support infinite file fragmentation as they reach their metadata limit. In addition, Microsoft Drive Optimizer is also responsible for performing the TRIM command on SSDs.

So do you think we should leave disk optimizer enabled and forget about it?
