Who will be the solid state hard disk interface Who will become the mainstream of the future-3u8895

Who is the master of solid-state hard disk interface who will become the mainstream in a complete set of PC requires a lot of parts, but as one of the most important components of the PC, a part of the hard disk often became the drag system, especially in the mechanical hard disk, due to physical restrictions on the mechanism, performance has been unable to upgrade. But the performance of the whole platform is greatly improved, the speed of the hard disk must not be revolutionary. PC in this revolution, the rapid development of SSD both have a significant improvement in price and capacity, the speed is greatly improved, SSD read and write performance have reached the 2247MB s and 949MB s of terror. However, in this revolution, in order to achieve faster, hard disk interface is also evolving, what are the mainstream interface today we’ll talk about the hard disk? Who will become the mainstream of the future? As everyone knows, as hard disk interface of different sizes is various, now can see at least SATA, mSATA, M.2, SATA, Express, PCI-E and U.2, the first detailed understanding of the types and characteristics of each interface. SATA 6Gbps:   SATA 6Gbps interface; SATA interface is a standard hard disk interface SATA 6Gbps interface, in fact this is not standard, the accurate name is SATA III, the interface speed is 6Gbps only, but now we used this argument. SATA 6Gbps interface is the most common HDD SSD hard disk interface, most people now buy hard disk are using this interface. As the most widely used of the hard disk interface, 6Gbps interface is the biggest advantage of SATA is mature, the bandwidth of 6Gbps while compared to the new 10Gbps interface or 32Gbps bandwidth is much worse, the current mainstream SSD still continue to use them, with the performance of SSD gradually increased, the standard has become a major bottleneck of SSD. MSATA interface: mSATA interface is an important process for the miniaturization of SSD, but mSATA still did not get rid of some defects of SATA interface, for example, is still the SATA channel, the speed is still 6Gbps, the interface of SATA potential is also so, in order to further development to seek new means. M.2 interface:   M.2 interface can support both SATA and PCI-E channels, the latter is more likely to improve the speed, start the M.2 interface using PCI-E 2 x2 channel, the theory of bandwidth of 10Gbps, which also broke through the SATA interface transmission bottleneck theory. Now the M.2 interface completely turns to PCI-E 3 X4 channel, the theoretical bandwidth reaches 32Gbps, far higher than the previous level, greatly improving the SSD performance potential. At the same time, the use of M.2 interface SSD also supports the NVMe standard, compared to the current mainstream AHCI, through the new NVM. 谁主沉浮 固态硬盘接口谁将成为未来主流   在一套完整的PC上需要很多部件组成,然而作为PC中最重要的部件之一,硬盘往往成了最拖累系统的一部分,特别是在机械硬盘上,由于物理机制的限制,性能一直无法提升。但是想要整套平台的性能有着极大的提升,硬盘的速度不得革命。   在PC这场革命中,固态硬盘飞速发展无论是在价格还是容量方面都有着明显的进步,在速度上更是有很大的提升,SSD读写性能都达到恐怖的 2247MB s与949MB s。然而在这场革命中,为了实现更快的速度,硬盘的接口也在不断进化,今我们就来谈谈硬盘的主流接口都有哪些?谁将成为未 来主流?   众所周知,视硬盘的大小不同硬盘接口也是多种多样的,现在能见到的至少有SATA、mSATA、M.2、SATA Express、PCI-E及U.2等,下面就先详细了解下每个接口的规格和特点。   SATA 6Gbps接口:  SATA 6Gbps接口   SATA是硬盘接口的标准规范,实际上SATA 6Gbps接口这个说法并不规范,准确的称呼是SATA III,接口速度是6Gbps而已,只是现在大家习惯这个说法了。SATA 6Gbps接口是目前最最常见的HDD SSD硬盘接口,大部分人现在买的硬盘都在用这种接口。   作为目前应用最多的硬盘接口,SATA 6Gbps接口最大的优势就是太成熟了,6Gbps的带宽虽然比起新接口的10Gbps甚至32Gbps带宽差多了,目前主流SSD依然继续使用它们,随着固态硬盘的性能逐渐增强,这些标准已经成为限制SSD的一大瓶颈。   mSATA接口:   mSATA接口是SSD小型化的一个重要过程,不过mSATA依然没有摆脱SATA接口的一些缺陷,比如依然是SATA通道,速度也还是6Gbps,SATA接口的潜力也就是这样了,要想进一步发展还得寻找新的手段。   M.2接口:     M.2接口可以同时支持SATA及PCI-E通道,后者更容易提高速度,一开始的M.2接口使用的是PCI-E 2.0 x2通道,理论带宽10Gbps,这也已经突破了SATA接口理论传输瓶颈。现在M.2接口全面转向PCI-E 3.0 x4通道,理论带宽达到了32Gbps,远高于之前水准,大大提升了SSD性能潜力。同时,使用M.2接口固态硬盘还支持NVMe标准,相比目前主流的 AHCI,通过新的NVMe标准接入的SSD,可以获得大幅度的性能提升。    PCI-E接口:   早在SATA接口的SSD发展之初,PCI-E接口的SSD就出现了,因为后者的优势实在太大了,其他SSD不论采用什么接口,都是从SATA 向原生PCI-E走进,而PCI-E接口的SSD直接是一步到位,省去了中间过程。不过PCI-E硬盘最初多用于企业级市场,因为它需要不同的主控,性能 高的同时成本也高了,消费级市场也没多少需求,只是这两年来PCI-E硬盘才在高端消费级市场上崛起。   SATA Express接口: SATA Express接口   在6Gbps速度之后,SATA接口要想继续提高速度已经很难了,SAS接口倒是可以把接口提高到12Gbps,但那是针对企业级市场的,对原 接口做了很大变动,而且后者对成本并不敏感,但是消费级市场就不一样,要考虑到现实,对此SATA-IO给出的解决方案是SATA Express接口。   SATA E的物理接口实际上是通过SATA 6Gbps接口改造的,推出有2年时间了,不过就目前的情况来看SATA E普及之路还非常遥远,唯一明智的就是向下兼容了SATA 6Gbps接口。   U.2接口: U.2接口的Intel 750硬盘及U.2线   对于U.2接口,到底是个什么鬼?U.2别称SFF-8639,是由固态硬盘形态工作组织(SSD Form Factor Work Group)推出的接口规范。U.2不但能支持SATA-Express规范,还能兼容SAS、SATA等规范。所以可以简单认为U.2接口是四通道版本 的SATA-Express接口,其理论带宽高达32Gbps与M.2接口无异,目前正式开卖的也只有Intel的750系列。   全文总结:   面对这么多的接口,到底谁将成为未来主流呢?SATA 6Gbps虽然在现在的硬盘市场上,依然还是主流,但规格上已经落伍,普通用户对性能的要求谈不上苛刻的,SATA 6Gbps很长一段时间内都将是最主要的选择。   mSATA不用说了,几乎已被淘汰了,M.2接口现在风头最劲,在传输带宽,容量等方面都有很大的优势。950系列固态硬盘的发布使得M.2接 口不再只使用在超极本上,在DIY领域也同样可以使用,并且今年100系列主板的发布,M.2接口几乎成为了标配,这无疑成为推动M.2接口发展的强动 力。   PCI-E显卡虽然要占据一个显卡插槽位,但它的优势非常明显,对主板没有特殊要求,在高端市场上依然会占有一席之地。   SATA E接口未老先衰,到今天为止只剩下尴尬了。U.2 接口不论性能还是新技术支持都走在了前列,它被众人看好会成为未来接口之星,但是小编认为可没那么乐观,毕竟现象主板的支持力度还是太小。小编认为M.2 接口的优势更大,M.2接口速度和技术都不输U.2接口,平台方面,100系主板将支持到PCI-E3.0 x4 M.2接口,通道数量也会有较大提高带宽和扩展能力都能达到极大的提升,这无疑是M.2 SSD的普及而铺路,相信在以后M.2固态硬盘将会逐渐占据存储市场。相关的主题文章:
