PCI Express Mini Card (also known as Mini PCI Express, Mini PCIe, Mini PCI-E, mPCIe, and PEM), based on PCI Express, is a replacement for the Mini PCI form factor. It is developed by the PCI-SIG . The host device supports both PCI Express and USB 2.0 connectivity, and each card may use either standard.
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.
The mezzanine adapter connects to the blade server using a PCI Express ×4 link, uses less than 9 watts, has bandwidth up to 800 MB/s and latency as low as 50 microseconds. [ 1 ] The PCIe adapter connects to the server using a PCI Express version 1.0 ×4 link, ×8 link, or version 2.0 ×4 link, depending on model.
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 ...
The SSD 310, Intel's first mSATA drive was released in December 2010, providing X25-M G2 performance in a much smaller package. [12] [13] March 2011 saw the introduction of two new SSD lines from Intel. The first, the SSD 510, used an SATA 6 Gigabit per second interface to reach speeds of up to 500 MB/s. [14]
Historically, most SSDs used buses such as SATA, SAS, or Fibre Channel for interfacing with the rest of a computer system. Since SSDs became available in mass markets, SATA has become the most typical way for connecting SSDs in personal computers; however, SATA was designed primarily for interfacing with mechanical hard disk drives (HDDs), and it became increasingly inadequate for SSDs, which ...
Support for up to 20 PCI Express (PCIe) lanes (up to 38-40 lanes for the nForce4 SLI x16). Reference boards are set up with one x16 slot and three x1 slots, leaving 1 lane unused. Support for up to 10 USB 2.0 ports. Support for 4 SATA and 4 PATA drives, which can be linked together in any combination of SATA and PATA to form a RAID 0, 1, or 0+1.
