ngff接口的ssd是什么？与msata接口的ssd有什么区别
据我们所知Thinkpad第四代机型主板上的接口变了，变成NGFF口了，所以鸿利在线特意写一片帖子看看和之前的MSATA口有什么区别。<div><br></div><div><span style="color: rgb(51, 51, 51); font-family: arial, 宋体, sans-serif; line-height: 25px; text-align: -webkit-auto; text-indent: 28px; ">NGFF接口作为Intel为超极本量身定做的新一代接口标准，其尺寸仅为42mmX22mm，单面布置NAND颗粒的话厚度为2.75mm，双面的话厚度则是3.85mm，而目前mSATA接口的SSD尺寸为51mmX30mm，单面厚度就达到了4.85mm。NGFF接口相对mSATA来说体积进一步减小，更加节省空间。</span></div><div><span style="color: rgb(51, 51, 51); font-family: arial, 宋体, sans-serif; line-height: 25px; text-align: -webkit-auto; text-indent: 28px; "><br></span></div><div><span style="color: rgb(51, 51, 51); font-family: arial, 宋体, sans-serif; line-height: 25px; text-align: -webkit-auto; text-indent: 28px; "><br></span></div><div><span style="color: rgb(51, 51, 51); font-family: arial, 宋体, sans-serif; line-height: 25px; text-align: -webkit-auto; text-indent: 28px; "><br></span></div><div><div><span style="font-family: arial, 宋体, sans-serif; color: rgb(51, 51, 51); line-height: 25px; text-indent: 28px; ">

mSATA接口的SSD体积为51mmx30mm，单面厚度就有4.85mm，而NGFF标准的只有42mmx22mm，可双面布置NAND颗粒，单面厚度2.75mm，双面布置也只有3.85mm，体积进一步缩小，功能上则为加速设备或者SSD所优化。</div><div class="para" style="margin-bottom: 15px; line-height: 25px; text-indent: 2em; "><br></div></span></div></div><div><div style="text-align: -webkit-auto;"><font color="#000000" face="微软雅黑, 黑体, Verdana" size="5"><span style="line-height: 24px;">优势2<br></span></font><div class="para" style="color: rgb(51, 51, 51); margin-bottom: 15px; text-indent: 2em; line-height: 25px; font-family: arial, 宋体, sans-serif; ">相比mSATA NGFF SSD可通过增加长度来增加容量 与mSATA接口SSD相比，NGFF标准SSD的宽度、厚度都是相同的，只有长度不同，而NGFF总共讨论了5种不同的长度，包括20mm、42mm、60mm、80mm以及120mm，其中42mm、60mm及80mm版本最有可能成为最终标准，越长代表有限的空间能装下的闪存颗粒越多，那容量也越大。</div><div class="para" style="color: rgb(51, 51, 51); margin-bottom: 15px; text-indent: 2em; line-height: 25px; font-family: arial, 宋体, sans-serif; "><br></div><h2 class="headline-1" style="margin-top: 65px; margin-bottom: 18px; font-size: 24px; font-family: 微软雅黑, 黑体, Verdana; font-weight: 500; line-height: 22px; clear: both; zoom: 1; position: relative; left: -30px; color: rgb(0, 0, 0); "><span class="headline-1-index" style="width: 24px; height: 25px; color: rgb(204, 204, 204); line-height: 25px; text-align: right; font-size: 20px; display: block; float: left; margin-right: 6px; ">3</span><a name="3" style="color: rgb(19, 110, 194); "></a><a name="sub9235475_3" style="color: rgb(19, 110, 194); "></a><span class="headline-content" style="line-height: 24px; ">优势3</span><span class="text_edit editable-title" data-edit-id="9218578:9235475:3" style="margin-left: 10px; "><a href="http://baike.baidu.com/link?url=ZN7ov21TuaVUl5o9me-OTmyiuv1OhgrfBjXbA1hDhCkCu2Z62XE-MZWoA80kkXVKrjhaa2CuU8_UhZqCdmUooa#" class="nslog:1019" title="编辑本段" style="text-decoration: none; color: rgb(19, 110, 194); height: 15px; line-height: 16px; width: 52px; padding-left: 18px; background-image: url(http://baike.bdimg.com/static/lemma/view3/img/icon-view_a463f249.gif); background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; background-position: -85px 12px; background-repeat: no-repeat no-repeat; "></a></span></h2><div class="para" style="color: rgb(51, 51, 51); margin-bottom: 15px; text-indent: 2em; line-height: 25px; font-family: arial, 宋体, sans-serif; ">相比mSATA支持接口规范更多样化 制定中的NGFF有两种接口：Socket 2和Socket 3，前者支持SATA、PCI-E x2接口的SSD、WWAN及其他非存储设备。Socket 3支持专为高性能存储设计，可支持PCI-E x4接口，体积更小的同时带宽高达4GB/s。相比于mSATA所支持SATA接口规范，NGFF更多样化，拥有更高的理论接口传输速度。</div><div class="para" style="color: rgb(51, 51, 51); margin-bottom: 15px; text-indent: 2em; line-height: 25px; font-family: arial, 宋体, sans-serif; "><br></div><h2 class="headline-1" style="margin-top: 65px; margin-bottom: 18px; font-size: 24px; font-family: 微软雅黑, 黑体, Verdana; font-weight: 500; line-height: 22px; clear: both; zoom: 1; position: relative; left: -30px; color: rgb(0, 0, 0); "><span class="headline-1-index" style="width: 24px; height: 25px; color: rgb(204, 204, 204); line-height: 25px; text-align: right; font-size: 20px; display: block; float: left; margin-right: 6px; ">4</span><a name="4" style="color: rgb(19, 110, 194); "></a><a name="sub9235475_4" style="color: rgb(19, 110, 194); "></a><span class="headline-content" style="line-height: 24px; ">优势4</span><span class="text_edit editable-title" data-edit-id="9218578:9235475:4" style="margin-left: 10px; "><a href="http://baike.baidu.com/link?url=ZN7ov21TuaVUl5o9me-OTmyiuv1OhgrfBjXbA1hDhCkCu2Z62XE-MZWoA80kkXVKrjhaa2CuU8_UhZqCdmUooa#" class="nslog:1019" title="编辑本段" style="text-decoration: none; color: rgb(19, 110, 194); height: 15px; line-height: 16px; width: 52px; padding-left: 18px; background-image: url(http://baike.bdimg.com/static/lemma/view3/img/icon-view_a463f249.gif); background-attachment: initial; background-origin: initial; background-clip: initial; background-color: transparent; background-position: -85px 12px; background-repeat: no-repeat no-repeat; "></a></span></h2><div class="para" style="color: rgb(51, 51, 51); margin-bottom: 15px; text-indent: 2em; line-height: 25px; font-family: arial, 宋体, sans-serif; ">相比mSATA，传输速度更快 采用PCI-Express x2传输标准的NGFF接口SSD最大连续速度达到了700MB/s，写入也高达550MB/s，4K 随机读写IOPS分别达到了100K及90K。</div></div></div>
