We just finished migrating a lot of hardware from our T110 into our T130 but realized that the slightly smaller case leaves us one slot short for a 5th hard drive. However, I did notice that even after populating all the PCIe slots, I see a PCIe 1x slot on the front of the motherboard facing the chassis. I don't see anything describing this slot in the owner's manual. Can anyone confirm if that additional 1x looking slot is usable for any hardware or if that slot is reserved for something very specific pertaining to server management or something?
Alternatively, would anyone recommend me getting an mSATA to USB 3.0 adapter plug and just using the onboard USB 3.0 port for our 5th hard drive? Or would performance be better served using the SATA connector?
