PCIe 6.0 controller is coming: speed upgrades, bandwidth up to 256GB/s

Although the current PCIe 5.0 specifications of the hard disk has not yet been listed, but the PCI-SIG organization in the early days officially released the PCIe 6.0 standard specification, and recently Rambus announced the launch of a PCIe 6.0 controller, claiming to be able to support all the new features of this specification.

The controller's PCIe 6.0 transmits data rates of 64GT/s, requiring only ×1 channel to achieve 8GB/s unidirectional physical bandwidth, which requires ×4 channels to achieve under the PCIe 4.0 specification; in the case of ×16 channels, its bidirectional bandwidth can reach 512GB/s, and if it is a multi-TB hard disk, it only takes a few seconds to fill, which shows how significant the rate increase of the new specification is.

In addition to being very fast, PCIe 6.0 is also naturally backward compatible, can support PCIe 5.0, 4.0 and 3.0/3.1; it also supports endpoints, boot ports, dual-mode, switch port configurations, and integrated IDE, can optimize performance and resist attacks, etc. There are still many new features, but the key points are still concentrated on the rate.

Of course, in the current PCIe 5.0 hard disk is not yet popular (even PCIe 4.0 hard disk is not yet popular), the existence of this controller is more or play a forward role, showing us the charm of the future hard disk ultra-high transmission speed. Rambus also did not announce the shipment time of this controller, referring to the possible time to market of PCIe 5.0 hard drives, when do you think we will see devices that support PCIe 6.0?
