What type of controller you have? Is it a PXI-8156B, PXI-8170, PXI-8176, other?
In theory you could use any 2.5" hard-drive. See KnowledgeBase linked below:
KnowledgeBase 23DDKSV7: What Kind of Hard Drive Is in My PXI Controller?However, I would first check the manual of the hard-drive to see what does it require.
If you have a PXI-8174, PXI-8175 or PXI-8176 controller you can see the specifications of the hard-drives that ship with these controllers at the following link:
Fujitsu Hard-drives used in PXI-8171 family of controllersHope this helps,
