Since you asked:

The motherboard manual claims it supports SATA 2 (3Gb/s). However, ada2
is an SSD, and camcontrol identify ada2 reports:
pass2: <KINGSTON SVP200S37A60G 502ABBF0> ATA-8 SATA 3.x device
pass2: 150.000MB/s transfers (SATA, UDMA5, PIO 8192bytes)
protocol ATA/ATAPI-8 SATA 3.x
device model KINGSTON SVP200S37A60G
[...]
so FreeBSD doesn't appear to know that.
