M.2模块的外形是长方形，在短邊一侧有一个连接器（臺灣俗稱「金手指」，有最多67针的75个点位，0.5毫米间距，各针分布在PCB的两短邊），并在另一侧短边的中心有一个半圆形安装固定孔。连接器上的各引脚额定最多50V和0.5A，而连接器本身要求耐受最低60次拔插。M.2标准允许模块寬度为12、16、22和30毫米，長度16、26、30、38、42、60、80和110毫米。市售M.2 擴充卡主要是22毫米寬度，長度有30、42、60、80和110毫米等规格[2][4][10][13]。對於固態硬碟適用的 M.2 模組，最常見的尺寸為 22mm (寬) x30mm (長)、22mm x 42mm、22mm x 60mm、22mm x 80mm 和 22mm x 110mm。這些擴充卡將會依據上述的尺寸來稱呼：前兩位數代表寬度 (都是 22mm)，而剩餘的位數則是代表長度，從 30mm 起到 110mm 長。因此，M.2 固態硬碟被區分為 2230、2242、2260、2280 和 22110[14]。

m.2ssd是什么

The meaning of OBJECTIVE LENS is a lens or system of lenses in a microscope, telescope, etc., that forms an image of an object.

Ocular lenses are also called the eyepiece. This contains a system of lenses that magnify further the image formed by the objective lenses and projects it ...

M.2模块的PCB板提供最多75個點位的连接器；取决于模块类型，部分针位被去除以存在一个或多个防呆鍵位。主机上的M.2连接器（插槽）可能填充一个或多个匹配的接口，这取决于主机可接受的模块类型；截至2014年4月，主机侧的连接器可以只填充一个防呆鍵位（无论B key或 M Key）[4][10][16][17]。此外，用于SATA或双通道PCI Express (PCIe ×2)的M.2插槽被称为"socket 2 configuration"或者"socket 2"，用于四通道PCI Express (PCIe ×4)的插槽被称为"socket 3 configuration"或"socket 3"[1][18]。

Socket 1主要針對無線網卡，對應的防呆鍵位為A Key。M.2 SSD 主要適用於 Socket 2、Socket 3這兩種插槽，Socket 2插槽可以支援走 SATA 及 PCIe x2通道的M.2 SSD，所對應的鍵位為 B Key，而 Socket 3插槽則支援走 PCIe x4通道的M.2 SSD，對應的鍵位為 M Key，兩種插槽因為防呆缺口的位置不一樣，所以無法混用，不過市面上有些 M.2 SSD 產品為了能同時兼容於兩種插槽，便把金手指的部分設計成 B+M Key 的形式，但是能夠插得進去，不代表就能夠正常使用，因為某些主機板上的M.2插槽僅能支援 PCIe 通道，如果你插入 SATA 的M.2 SSD，那麼就會無法偵測到，除非廠商在設計時，就已經加入 SATA 及 PCIe 的控制器，使它能夠兼容於兩者，這部分各家不一，只能從主機板規格表上自行查詢。另外，如果是走 SATA 通道的M.2 SSD，那麼一樣會受到6Gb/s 頻寬的限制，在傳輸效能上等同於2.5吋的 SATA SSD[20]。
