Can anyone tell me the latest Mac Book Pro express34 card speed?
Is it a 1Lane or a 4Lane speed.
All ExpressCards are 1-lane.
I have a 4Lane Express34 card right in front of me.
I heard the older Mac Book Pro is 1Lane speed and the latest Mac Book Pro is 4Lane speed.
Forgive my ignorance, but what's the difference between 1Lane and 4Lane?
1Lane up to 250MB/s, 4 Lane, 1GB/s
I am helping a company test out a solution.
They can put a Desktop PCI-e card to a Laptop by using this device.
however, the MBP i have is older version which is limited to 250MB/s and in the reality, it gave me around 220MB/s
The ExpressCard 1.0 spec is x1 only.
