However, after this BIOS mod, the SSD can reach PCIe Gen 3.0 speeds (Max 8 GT/s; 3.9 GB/s) so the speed tests look like this:

# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.
# Turn on execshield
# 0 completely disables ExecShield and Address Space Layout Randomization
# 1 enables them ONLY if the application bits for these protections are set to “enable”
# 2 enables them by default, except if the application bits are set to “disable”
# 3 enables them always, whatever the application bits
