My laptop screen is beginning to have some issues and it's not worth fixing or even selling AFAIC so I'm considering using it as a NAS but it has no onboard gigabit nor USB 3.0.

I know I can't get gigabit speeds over USB 2.0 so I'm curious to know whether it is possible get reliable gigabit speeds over a PC ExpressCard (54) slot.

Thanks in advance.
 
"ExpressCard utilizes two interconnect technologies, the most important of which is PCI Express (PCIe). ExpressCards featuring PCIe 1X technology are capable of 2.5Gb/s per direction, giving an ExpressCard operating in full duplex mode an approximate throughput of 250MB/s x 2, or 500MB/s of throughput..

ExpressCard's bandwidth provides much higher performance
PCIe 1X technology based ExpressCards are capable of 2.5Gb/s per direction, allowing for realization of applications, like host adapters, which underperform or are impossible with PC Cardbus. Examples of bottlenecked Cardbus host adapters, that don't tax ExpressCard are Gigabit Ethernet (GbE) and FireWire 800 (IEEE 1394.b). "
