Windows 10 can identify the proper optimization for different types of storage devices. Once Windows 10 recognizes the SSD, it will perform TRIM.
Please check out this other post in the official forums that shows evidence that this may not necessarily be true. There, it's the i7 1TB model just like the OP asked, and it's observed that Windows is actually defragging the drive instead of trimming. Again, the cause is identified as possibly because the 1TB is in fact two 512GB drives in RAID 0. In that thread, the suggestion is simply to disable the scheduled maintenance and to do the trim manually.
So, Mark Ole, the question still stands. What is happening? And can we make sure Windows identifies the SSD(s) properly and performs an automatic trim on schedule?
For everyone reading, this is important, because defragging an SSD drive reduces its lifetime.
