From the AS SSD screenshot, it doesn't look like you're using AHCI mode. Are you sure you have it connected to one of the Intel SATA 3 ports?

Looks normal now. Random 4K write looks a wee bit on the low side but it might just be power saving settings or something.

I'd leave it as is (saves on the electricity bill). The only difference you'll notice is in benchmarks, anyway.
