   I still remember the system Windows7 Experience Index, a disk that score 5.9 points, 7.9 points in the remaining four in front, it seems to have told us that mechanical hard destined to be eliminated by the times. Irresistible force of SSD solid state drive, completely broke the mechanical hard over the years to rule Winchester structure in the field of computer hardware. Several times the transmission performance SSD HDD mechanical hard disk, so that ordinary users and enthusiasts of all experience increase exponentially. Today, the development experience over the years, and at Kingston HyperX SSD as the representative of the brand, has completely dominated the hard disk storage market.

  In this revolution in storage, in order to achieve faster, more use of the environment, better experience, SSD interfaces are evolving innovations, like the mainstream SATA interface SSD there, M.2 interfaces, PCIe Interface and mSATA interface. This four common interfaces What is the difference? But also for what platform to use it? Let us explain one by one.

 

  SATA3.0 interface represents products: Kingston UV400 Series

 

  As the most widely used hard drive interface, SATA3.0 interfaces biggest advantage is mature. Ordinary 2.5 inches SSD and HDD hard drives use this interface, a theoretical bandwidth 6Gbps, although compared to 10Gbps and 32Gbps bandwidth of the new interface has a certain gap, but the average 2.5 inches SSD to meet the needs of everyday applications most users, 500MB / s read and write speeds of about adequate. For 100MB / s read and write speed on the left and right HDD mechanical hard disk, 6Gbps bandwidth is still far from the bottleneck, can only blame HDD hard disk development is too slow, memory speed has been no qualitative change.

  虽然SATA3.0接口规格已经推出有一段时间,但"廉颇岁老,尚善饭否"。大多数用户对SSD性能的要求谈不上极端苛刻,而且还要考虑选购时的性价比因素,因此SATA3.0接口在很长一段时间内都将是主流大众的选择。说起SATASSD,就不得不提电商销售名列前茅的金士顿UV400系列。UV400系列其采用Marvell四通道主控芯片,搭配高品质的闪存颗粒,读写速度最高可达550、500MB/s,接近于SATA3.0接口的传输瓶颈,为用户带来极速的读写体验。且金士顿UV400走亲民的价格路线,无论你是初装机还是升级,金士顿UV400SSD绝对是一款性价比最出色的产品。

 

  PCIe接口代表产品:HyperXPredatorPCIeSSD

  在传统SATA硬盘中,当我们进行数据操作时,数据会先从硬盘读取到内存,再将数据提取至CPU内部进行计算,计算后再反馈给内存,最后写入至硬盘中;而PCIe接口就不一样了,数据直接通过总线与CPU直连,省去了内存调用硬盘的过程,传输效率与速度都成倍提升。简单的说,我们可以把两种通道理解成两辆相同的汽车,PCIe通道的汽车就像是在高速上行驶,而SATA通道的汽车就像是在崎岖山路上行驶。很显然,PCIeSSD的传输速度会远大于SATASSD。

  HyperXPredatorPCIeSSD是众多PCIe接口SSD中的佼佼者,它采用PCI-E2.0x4接口,半高式设计,主控为Marvell88SS9293,读取速度和写入速度分别达到了1400MB/s和1000MB/s,是HyperX高端固态硬盘产品中速度最快的产品,读写速度也远超SATA接口的SSD产品。

 

  虽然PCIeSSD有诸多好处,但也不是每个人都适合。PCIeSSD由于闪存颗粒和主控品质极高,总体成本也相对较高,相比传统SATA接口固态硬盘的售价要贵一些。另外,由于PCIe会占用总线通道,入门以及中端平台CPU通道数较少,也不太适合使用PCIeSSD。只有配合Z170、X99这样顶级平台,才可以完全发挥PCIeSSD的性能。总的来说,如果你是在组装专业工作室用机,或是骨灰发烧级玩家,亦或是一个不差钱的土豪,那么HyperXPredatorPCIeSSD是决对正确的选择!

 

  M.2接口代表产品:金士顿G2系列

  M.2接口,最初叫做NGFF(NextGenerationFormFactor),宽度22mm,单面厚度2.75mm,双面闪存布局也不过3.85mm厚。M.2接口产品有丰富的可扩展性,最长可以做到110mm,可以提高SSD容量。此外,M.2接口可以同时支持SATA及PCI-E通道,后者更容易提高带宽,如果是采用SATA通道的M.2接口固态硬盘,则读写速度在550MB/s左右。

  其实前面介绍的HyperXPredatorPCIeSSD产品本身拥有双重接口,从PCIe转接卡中取下,即可转换为M.2接口的SSD,并且读取速度和写入速度同样可以达到1400MB/s和1000MB/s。

  金士顿G2系列M.22280SSD是一款SATA通道的M.2SSD,宽度22mm,长度80mm,有120G、240G及480G三种容量,精选MLC闪存,通过先进的磨损均衡和TRIM支持优化技术,金士顿G2系列可在使用寿命期间保持一致的速度。此外,虽然性能上与SATASSD比起来没有太大优势,但贵在无外壳设计,纤薄,且价格跟SATASSD差不多,是带M.2接口的超薄类笔记本、Mini/HTPC主机升级不错选择。

 

  上面两款都是M.2接口,如何分辨出哪个是PCI-ESSD哪个是SATASSD?在弄清楚这个问题之前,我们先来解答几个常见问题。

 

  1、同是M.2接口,为什么会有PCI-E和SATA之分?

 

  这是因为两者所走的通道不同,M.2有两种接口定义:Socket2和Socket3。Socket2支持SATA、PCI-EX2通道的SSD,Socket3专为高性能存储设计,支持PCI-EX4。HyperXPredatorSSD走的是PCI-E通道,而金士顿G2系列M.2走的是SATA通道。走的路不一样,性质也就截然不同了。

 

  2、有M.2接口的主板都能使用M.2SSD?

 

  非也非也,不同主板的M.2接口所支持的通道是不同的,有的仅持PCI-E通道,其规格说明里关于M.2的描述有标明。而有的则兼容SATA和PCI-E两种通道。所以如果您想购买M.2SSD,先要清楚了解自己的主板上的M.2接口是支持哪种通道的。

 

  3、什么决定M.2SSD所走的通道?

 

  主控决定了接入M.2接口的SSD是走PCI-E通道还是SATA通道。例如HyperXPredatorSSD的主控是Marvell88SS9293主控,这是一款PCI-E控制器,而金士顿G2系列M.22280SSD采用的是SATA控制器。

 

  4、性能差别有多大呢?

 

  走的通道不一样,速度自然有差别。SATA3.0通道的理论带宽是6Gb/s.理论极限传输速度600MB/s,所以跟市面所有的SATA接口SSD一样,金士顿G2系列M.22280SSD的最高读取速度不超过600MB/s,而主板M.2接口走PCI-E通道传输通道带宽为10Gb/s。HyperXPredatorSSD的连续读写达到1400MB/s和1000MB/s,完全超过了SATA3.0的极限传输速度。

 

  mSATA接口代表产品:金士顿MS200系列

 

  早期,为了更适应于超极本这类超薄设备的使用环境,针对便携设备开发的mSATA(miniSATA)接口应运而生。你可以把它看作标准SATA接口的mini版,物理接口跟miniPCIe接口一样。

 

  mSATA interface is an important process of miniaturization SSD, mSATA, but still not out of the SATA interface is still the SATA channels, is the speed of 6Gbps. MSATA interface to a number of reasons did not make up the fire, but was replaced by the more upgrade potential M.2SSD.

  Of course, if you are upgrading old or newly purchased mini notebook with mSATA interface to the host, consider Kingston MS200 series mSATASSD, she high-quality MLC flash memory chips, read speed up to 550MB / s, write up 530MB / s, is a rugged, high performance and durability of SSD products.

 

  In these 60 years of computer development, from the initial punch card records to today's high-performance SSD, a storage medium has undergone enormous changes. In recent years, SSD is developing rapidly, from the evolution of the interface morphology can spy or two. Now has SATA, mSATA, M.2, PCIe interfaces, the devices are used in a variety of platforms. As a global leader in storage, Kingston's SSD product line covers complete, I believe there will be a high-speed SSD product for you.
