Thanks for your reply, Frank! Be that as it may. As platters go. I bought this 1Tb WD blue, because all the stats for it indicated it was faster that all the major competitors, and interestingly, faster than their "high-end" Black counterpart. I also bought it, because it was quieter than all the others. That said; given that the port it runs off of, and the drive is truly a Sata 3 (3.1). Why won't FreeBSD treat it as such. Why does it penalize the drive? I have another Sata 3 drive on the second Sata 3 port, that FreeBSD actually treats as what it is: ada1 at ahcich1 bus 0 scbus1 target 0 lun 0 ada1: ACS-2 ATA SATA 3.x device ada1: Serial Number W1F55VT9 ada1: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes) ada1: Command Queueing enabled ada1: 2861588MB (5860533168 512 byte sectors) ada1: quirks=0x1<4K> note the "quirks" - is that good, or bad? In the end, it appears that I have to purchase a slower rated (Sata 3) drive to get FreeBSD to treat it as a Sata 3 drive? It makes no sense to me. Which is why I came here; in hopes of finding out *why* it appears as it does. :) Thanks again, Frank! Oh! In case it matters; this is on 12 (CURRENT) -- Chris out...
