Drive numbering

Definition
Each PCIe version corresponds to a specific data transfer rate
between the processor and peripheral devices. Generally, a
version update corresponds to an increase in transfer rate.
• PCIe 1.x
• PCIe 2.x
• PCIe 3.x
The PCIe technology is under constant development. For the
latest information, see the PCI-SIG website.
PCIe devices communicate through a logical connection called
an interconnect or link. At the physical level, a link is composed
of one or more lanes. The number of lanes is written with an "x"
prefix with x16 being the largest size in common use.
• x1
• x2
• x4
• x8
• x16
These numbers correspond to the maximum link bandwidth
supported by the slot.
