    I have the 1 TB HDD + 32 GB SSD and in my Windows 10 defrag tool it shows "Optimization not available". Why am I unable to defrag my HDD? I've been able to in all other Windows versions regardless of HDD/SSD, although I've never had RAID before.

    I'm guessing that your system is using the 32GB SSD as a cache for the data on your 1TB HDD.

    If that is the case, then your 1TB drive is presented to your system as a logical disk volume through some kind of RAID controller. And I'm betting that Windows automatically disables defragmentation for RAID controllers, just to be conservative about it. If you check, I'd bet that the windows service for Disk Defragmentation is disabled.

    You CAN defrag a drive setup that uses the SSD as a cache. But honestly, it isn't going to get you any real world performance gains. At most, defraging a horribly fragmented drive will get you maybe 10% boost in random read speeds. And that is something you'll never ever notice in real world performance.

    Meanwhile, putting critical files on a pure SSD will give you a 10,000%-50,000% increase in random read speeds. That kind of puts the 0-10% in perspective.
