Picking drives with NCQ is enormously helpful.
Wow, didn't know about this feature!
Turns out some of my drives actually have NCQ but unfortunately the SATA
controllers don't seem to be compatible/supported (nvidia MCP51,
broadcom BCM5785 [HT1000]). Next time I'll check if the motherboard
supports NCQ before buying :)
Here's what I see in dmesg:
ata2.00: 586070255 sectors, multi 16: LBA48 NCQ (depth 0/32)
On further inspection, MCP51 should support NCQ:

Seems it's in the -mm tree, if I'm not mistaken? Guess I'll wait for it
to become merged into mainline.
