2.3.2 SATA Port
The PXI-3950 provides a SATA Gen. 1 port and is shipped with
a pre-installed 2.5" SATA hard drive. The SATA host controller
supports two modes of operation, the legacy mode using I/O
space and AHCI mode using memory space. You can also use
a 2.5" solid state disk (SSD) as a replacement SATA hard drive
for shock/vibration resistance.
