RAID HDD and Cache SSD for lowwer latency?

i would like to rebuild my home server.

i would like 4x4 TB drives in RAID 1+0

i also would like to know if i could add a small SSD as a cache drive for quick access times. so the directory loads up fast while the array spins up and syncs.

Is this possible. the current itx motherboard i have allows raid but doesnt allow intel SRT. can i run an SSD for Cache under software.

i was considering running WD dual drives in RAID0 and mirroring that array but the dual drives are incredibly expensive for their capacities.

what do you suggest.

    Disk striping will speed up your access but mirroring will slow you down. With caching, you can speed up the writes but first time read will be just as slow.

    What is your use case?

    Something like this will score well on benchmarks but in real life uses, benefit is questionable.
