SATA Express was an interface for connecting SSDs through SATA-compatible ports, optionally providing multiple PCI Express lanes as a pure PCI Express connection to the attached storage device. [152] M.2 is a specification for internally mounted computer expansion cards and associated connectors, which also uses multiple PCI Express lanes. [153]
DMI is essentially PCI Express, using multiple lanes and differential signaling to form a point-to-point link. Most implementations use a ×8 or ×4 link, while some mobile systems (e.g. 915GMS, 945GMS/GSE/GU and the Atom N450) use a ×2 link, halving the bandwidth. The original implementation provides 10 Gbit/s (1 GB/s) in each direction using ...
The specification was released on December 20, 2011, as a mechanism for providing PCI Express connections to SSDs for the enterprise market. Goals included being usable in existing 2.5" and 3.5" form factors, to be hot swappable and to allow legacy SAS and SATA drives to be mixed using the same connector family.
Exposed PCI Express lanes provide a pure PCI Express connection between the host and storage device, with no additional layers of bus abstraction. [9] PCI-SIG M.2 specification, in its revision 1.0 as of December 2013 [update] , provides detailed M.2 specifications.
It was claimed by ATI that having 2 chipsets with 20 PCI Express lanes would slow down data transfers when the chipset is working in multi-GPU configurations. Having all of the PCI Express lanes within the Northbridge claimed to be more efficient and less bottlenecking as compared to the nForce 4 16x SLI. The RD580 was called the "Radeon Xpress ...

Yes, the end of North I-25 Express Lanes construction is near. But first, there will be multiple full lane closures for the project's final steps. Multiple Interstate 25 closures planned as North ...
The choice of PCI Express also enables scaling up the performance of SATA Express interface by using multiple lanes and different versions of PCI Express. In more detail, using two PCI Express 2.0 lanes provides a total bandwidth of 1000 MB/s (2 × 5 GT /s raw data rate and 8b/10b encoding ), while using two PCI Express 3.0 lanes provides 1969 ...
