NGFF简介

NGFF (Next Generation Form Factor),与 NGFF 并列的是 2.5"(2.5”硬盘(包括HDD和SSD)厚度一般为9.5mm和7mm),NGFF现在已经改名为M.2,M.2有SATA 和PCIe两种总线标准。

M.2接口是一种新的主机接口方案,可以兼容多种通信协议,如sata、PCIe、USB、HSIC、UART、SMBus等。

M.2接口是为超极本(Ultrabook)量身定做的新一代接口标准,以取代原来的mSATA接口。无论是更小巧的规格尺寸,还是更高的传输性能,M.2都远胜于mSATA。

M.2接口,是Intel推出的一种替代MSATA新的接口规范。其实,对于桌面台式机用户来讲,SATA接口已经足以满足大部分用户的需求了,不过考虑到超极本用户的存储需求,Intel才急切的推出了这种新的接口标准。所以,我们在华硕、技嘉、微星等发布的新的9系列主板上都看到了这种新的M.2接口,现已普及。 [1] 与MSATA相比,M.2主要有两个方面的优势。第一是速度方面的优势。M.2接口有两种类型:Socket 2(B key——ngff)和Socket 3(M key——nvme),其中Socket2支持SATA、PCI-E X2接口,而如果采用PCI-E ×2接口标准,最大的读取速度可以达到700MB/s,写入也能达到550MB/s。而其中的Socket 3可支持PCI-E ×4接口,理论带宽可达4GB/s。

第二个是体积方面的优势。虽然,MSATA的固态硬盘体积已经足够小了,但相比M.2接口的固态硬盘,MSATA仍然没有任何优势可言。M.2标准的SSD同mSATA一样可以进行单面NAND闪存颗粒的布置,也可以进行双面布置,其中单面布置的总厚度仅有2.75mm,而双面布置的厚度也仅为3.85mm。而mSATA在体积上的劣势就明显的多,51mm×30mm的尺寸让mSATA在面积上不占优势,而4.85mm的单面布置厚度跟M.2比起来也显得厚了太多。另外,即使在大小相同的情况下,M.2也可以提供更高的存储容量。
