M.2 – Wikipedia

M.2, formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. It replaces the mSATA standard, which uses the PCI Express Mini Card physical card layout and connectors. M.2's more flexible physical specification allows different module widths and lengths, and, paired with the availability of more advanced interfacing features, makes the M.2 more suitable than mSATA for solid-state storage applications in general and particularly for the use in small devices such as ultrabooks or tablets.[1][2][3]

Computer bus interfaces provided through the M.2 connector are PCI Express3.0 (up to four lanes), Serial ATA3.0, and USB3.0 (a single logical port for each of the latter two). It is up to the manufacturer of the M.2 host or device to select which interfaces are to be supported, depending on the desired level of host support and device type. The M.2 connector has different keying notches that denote various purposes and capabilities of M.2 hosts and modules, preventing plugging of M.2 modules into feature-incompatible host connectors.[1][2][4]

In addition to supporting legacy Advanced Host Controller Interface (AHCI) at the logical interface level, M.2 specification also supports NVM Express (NVMe) as the logical device interface for M.2 PCI Express SSDs. While the support for AHCI ensures software-level backward compatibility with legacy SATA devices and legacy operating systems, NVM Express is designed to fully utilize the capability of high-speed PCI Express storage devices to perform many I/O operations in parallel.[1]:14[5]

Buses exposed through the M.2 connector are PCI Express3.0, Serial ATA (SATA)3.0 and USB3.0, which is backward compatible with USB2.0. As a result, M.2 modules can integrate multiple functions, including the following device classes: Wi-Fi, Bluetooth, satellite navigation, near field communication (NFC), digital radio, Wireless Gigabit Alliance (WiGig), wireless WAN (WWAN), and solid-state drives (SSDs).[6] The SATA revision 3.2 specification, in its gold revision as of August2013[update], standardizes the M.2 as a new format for storage devices and specifies its hardware layout.[1]:12[7]

The M.2 specification provides up to four PCI Express lanes and one logical SATA3.0 (6Gbit/s) port, and exposes them through the same connector so both PCI Express and SATA storage devices may exist in the form of M.2 modules. Exposed PCI Express lanes provide a pure PCI Express connection between the host and storage device, with no additional layers of bus abstraction.[8]PCI-SIG M.2 specification, in its revision 1.0 as of December2013[update], provides detailed M.2 specifications.[1]:12[9]

There are three options available for the logical device interfaces and command sets used for interfacing with M.2 storage devices, which may be used depending on the type of M.2 storage device and available operating system support:[1]:14[5][8]

The M.2 standard has been designed as a revision and improvement to the mSATA standard, with the possibility of larger printed circuit boards (PCBs) as one of its primary incentives. While the mSATA took advantage of the existing PCI Express Mini Card (Mini PCIe) form factor and connector, M.2 has been designed from the ground up to maximize usage of the PCB space while minimizing the module footprint. As the result of the M.2 standard allowing longer modules and double-sided component population, M.2 SSD devices can provide larger storage capacities and can also double the storage capacity within the footprints of mSATA devices.[1]:20,2223[3][10]

M.2 modules are rectangular, with an edge connector on one side (75 positions with up to 67 pins, 0.5mm pitch, pins overlap on different sides of the PCB), and a semicircular mounting hole at the center of the opposite edge. Each pin on the connector is rated for up to 50V and 0.5A, while the connector itself is specified to endure up to 60 mating cycles.[citation needed] The M.2 standard allows module widths of 12, 16, 22 and 30mm, and lengths of 16, 26, 30, 38, 42, 60, 80 and 110mm. Initial line-up of the commercially available M.2 expansion cards is 22mm wide, with varying lengths of 30, 42, 60, 80 and 110mm.[2][4][11][12]

Example codes: 2242 22mm wide, 42mm long, 2280 22mm wide, 80mm long.

An M.2 module is installed into a mating connector provided by the host's circuit board, and a single mounting screw secures the module into place. Usually suitable screws are provided with the hardware component on which the M.2 module is mounted (circuit board, M.2 to PCI-E adapter, etc.). The screw specifications for thread, length, and head-type can vary depending on the hardware manufacturer. Most commonly M2x3 screws with flat-head are used for this purpose (Thread diameter 2.0mm, length 3.0mm, thread-pitch 0.4mm). Components may be mounted on either side of the module, with the actual module type limiting how thick the components can be; the maximum allowable thickness of components is 1.5mm per side. Different host-side connectors are used for single- and double-sided M.2 modules, providing different amounts of space between the M.2 expansion card and the host's PCB.[3][4][11] Circuit boards on the hosts are usually designed to accept multiple lengths of M.2 modules, which means that the sockets capable of accepting longer M.2 modules usually also accept shorter ones by providing different positions for the mounting screw.[13][14]

PCB of an M.2 module provides a 75-position edge connector; depending on the type of module, certain pin positions are removed to present one or more keying notches. Host-side M.2 connectors (sockets) may populate one or more mating key positions, determining the type of modules accepted by the host; as of April2014[update], host-side connectors are available with only one mating key position populated (either B or M).[4][11][16] Furthermore, M.2 sockets keyed for SATA or two PCI Express lanes (PCIe2) are referred to as "socket2 configuration" or "socket2", while the sockets keyed for four PCI Express lanes (PCIe4) are referred to as "socket3 configuration" or "socket3".[1]:15[17]

For example, M.2 modules with two notches in B and M positions use up to two PCI Express lanes and provide broader compatibility at the same time, while the M.2 modules with only one notch in the M position use up to four PCI Express lanes; both examples may also provide SATA storage devices. Similar keying applies to M.2 modules that utilize provided USB3.0 connectivity.[4][16][18]

Various types of M.2 devices are denoted using the "WWLL-HH-K-K" or "WWLL-HH-K" naming schemes, in which "WW" and "LL" specify the module width and length in millimeters, respectively. The "HH" part specifies, in an encoded form, whether a module is single- or double-sided, and the maximum allowed thickness of mounted components; possible values are listed in the right table above. Module keying is specified by the "K-K" part, in an encoded form using the key IDs from the left table above; it can also be specified as "K" only, if a module has only one keying notch.[4][11]

Beside socketed modules, the M.2 standard also includes the option for having permanently soldered single-sided modules.[11]

M.2 sockets with an "E" slot support Dual-Band Wireless LAN/Bluetooth cards (2230 or 1216).[19]

Celebrity Big Brother 2017: Wikipedia RUINS final eviction twist by ‘REVEALING’ who leaves – Express.co.uk

The Channel 5 shows plan was to send whoever had received the lowest number of votes home in the last hurdle before the final, after presenter Emma Willis shared the news earlier this week.

But unfortunately, the person in charge of updating the reality shows page is believed to have put up an announcement that revealed the star who had gone.

The statement read that Jemma Lucy was the eighth housemate to be evicted on Day 23, but it has since been deleted.

The news may come as a huge disappointment for producers of the series, as they were keeping extremely tightlipped over the reveal.

As well as keeping any information of the twist off of press releases, they have been trying to ensure a social media blackout so that fans can experience the shock firsthand, according to reports.

But if its true, fans still have more of the Ex on the Beach star to come, as the star will be seen enjoying a cheeky kiss with Girls Aloud singer Sarah Harding in tonights episode.

While it appears the smooch is part of another one of the housemates games, viewers will be surprised given the notorious amount of fiery arguments between the pair.

In one recent altercation, the brunette slammed her rival and claimed her singing was out of tune.

Sarah was singing loudly on the sofas when Jemma asked: Is it just me, or is that out of tune?

But while ex-EastEnders star Shaun Williamson attempted to play peacekeeper by saying it was actually the fault of the air-con, it only made a brief respite in the womens constant feuding.

Express.co.uk has contacted a representative for Channel 5 asking for comment.

Celebrity Big Brothercontinues tonight at pm on Channel 5, with the finale airing tomorrow.

Jean Deaux – Wikipedia [New Song] – HotNewHipHop

Wikipedia Jean Deaux showcases her many talents on "Wikipedia."

Chicago has been making waves for it's unique and diverse hip-hop scenes, boasting an epic array of young rappers like Chief Keef, Chance The Rapper, and Mick Jenkins. Yet the scene has also birthed a talented wave of singers, including Jean Deaux. With a lovely voice and atmospheric aesthetic, Deaux has excelled on collaborations with the aforementioned Jenkins, as well as her own solo material. On that note, Jean has come through with a new single called "Wikipedia," in honor of the aspiring academic's favorite faux pas.

The smooth jam is produced by ROMderful, and serves as a worthy introduction to the up-and-comer's world. Insofar as the concept goes, Jean had the following to say about "Wikipedia:" People are going to try and tell you who you are every step of the way, they'll even knock you down to convince you. But you get stronger every time you get up on your feet and continue walking in your own truth."

It's a powerful message, and Jean continues to drop knowledge when elaborating on her creative process:

"Writing music depends on my mood. If I feel I have a lot of things bottled up they'll spill out in any convenient melody I can find in a song. 'Wikipedia' was like that.When I got the beat from ROM, I wrote the song on paper in like less than 10 minutes. Smino recorded me, and that was it. I spent my time after tour touching it up, the people that saw me perform it really connected with it and they were ready to have it."

Speaking of Smino, Jean Deaux recently toured North America with the St. Louis singer. If you're feeling Jean's first solo release of 2017, you should be pleased to know that she's hard at work on her next EP, which is still untitled.

Quotable Lyrics

Oh no, somebody at the door You know how she got that cola body cause she do that coka Know I seen her before, heard it through the grapevine Buzzin' through the phone lines, callin' for the fourth time

Nickelback Play ‘Wikipedia: Fact or Fiction?’ – Loudwire

Subscribe to Loudwire on

Welcome to the Nickelback edition of Wikipedia: Fact or Fiction?. In this episode of our signature series, we invited the entirety of Nickelback to prove and disprove whats written about them on Wikipedia.

This segment is packed with a ridiculous amount of fiction, so all you Wiki debunkers should love this one. Nickelback frontman Chad Kroeger actually corrected an entry about getting a $4,000 loan from his stepfather so the band could record the Hesher EP. Actually, only half the money was spent on recording, while the other half went to buying magic mushrooms. Kroeger quickly recouped the studio cost by slinging shrooms, eventually paying back his stepfather as well.

Nickelback also debunked an interpretation of their song Fly. Whoever wrote the Wikipedia entry believed that the song ends with Chad Kroeger killing himself, but the singer gave the X to that factoid.

The band also managed to clear up what happened to former drummer Mitch Guindon. Though Wikipedia says he left to go work at a car company, Nickelback say they actually kicked him out. Apparently, Guindon wasnt suited for the road anyway. He was not meant for the road, Chad claims. He was allergic to cold air. We got to the middle of Canada in winter, and obviously its gonna be cold as hell, and his skin started coming off his body. Hes like, Yeah, I cant do this.

Watch Nickelback correct their many Wikipedia pages in the clip above. Also, make sure to grab the bands newest album, Feed the Machine.
