Who can’t fool me! Teach you to choose the mobile storage device-oembios.bin

Nobody can fool me! Teach you to choose the mobile storage device in this paper from the Pacific computer network close to the lunar new year, I met a friend of such confusion: he wants to give the home to buy a U disc, dedicated TV inserted on the TV, father mother free time to watch. He said he bought a 16G U disk, but copied the network TV to the U disk, but found that half an hour more! Ask the author in the end, why not buy slag U plate? If the author did not personally encounter careful questioning, I really do not believe that until now there are young people do not know what USB2.0 and USB3.0 is. In the solution to friends, but also want to take this opportunity to science popularization of mobile storage related knowledge – in the end what kind of mobile storage media we need? Although do not know what is the USB 2 and 3 should not, but after all, not everyone is like that of any digital technology products and technology enthusiasts can understand the first time (especially as people are out of work every day, so the author talks) will tell you, the USB 3 interface is blue, good let we all know there is a blue flag USB is the product of a new era. How important is it to know USB 3? The mobile storage device is an important degree you buy a USB 3 interface, when access to a computer with USB 3, you can get several times the speed of USB2.0. The following figure, take 64G U di OTG flash disk, a file with a USB 2.0 interface to write only 16.9MBps, but to the USB 3.0 interface is 49.8MBps, the speed gap can be so obvious. If you don’t have the idea of time and you don’t think it’s okay to copy the document, the author doesn’t say anything. USB 2 interface transmission speed, but bought a USB 3 interface U disk is not able to enjoy. You need to confirm your computer know that support USB 3 Blue interface, the formula can achieve considerable speed. The master machine as the author of a friend, but not the original USB interface, or copy network TV is estimated for several hours. Here I also want to remind you, native Windows 7 system does not support USB 3, you must install the driver. Windows 88.110 can be native support. Transmission speed USB 3 interface may be many of my friends will think their usual digital products and a variety of interface, memory card or USB port is not consistent if want to buy and buy Micro SD card, SD card, U disk and for daily use, more tired. So I recommend a relatively easy way, that is the combination method. It means to use a small package, one layer, one layer to use. I like the ordinary digital camera using a Micro SD card, then buy a fast enough, and then with the SD card, with a USB card reader, so things can act as a volume of three ways, mom.

谁也不能忽悠我!教你选好移动存储设备   本文转自太平洋电脑网   接近农历新年,笔者身边一位朋友遇到了这样的困惑:他希望给家里买一个U盘,专门存放电视剧插在电视机里,父亲母亲空闲时间可以随时观看。他说自己买了一个16G U盘,但复制网络电视机到U盘上却发现要半小时有多!就问笔者到底为何,是不是买到了渣U盘?如果不是笔者亲身碰到细细盘问,笔者还真不相信到现在还有年 轻人不知道USB2.0和USB3.0是何物。在给朋友解惑之余也希望借此机会向大家科普移动存储相关知识——到底我们需要什么样的移动存储介质?   虽然说不懂得什么是USB 2.0和3.0很不应该,但毕竟不是每个人都像数码爱好者那样任何科技产品技术都能第一时间了解(尤其像每天工作都是出外洽谈的人们),所以笔者就先告诉 大家,USB 3.0的接口是蓝色的,就好让大家都明白有个蓝色标志的USB口就是新时代产物。   知道USB 3.0有多重要么?重要程度就是你购买的USB 3.0接口的移动存储设备,当接入到带有USB 3.0的电脑上时,就可以获得几倍于USB2.0的速度。如下图,就拿闪迪OTG 64G U盘来说,同一个文件USB 2.0接口写入只有16.9MBps,然而到了USB 3.0接口就有49.8MBps,可以速度差距多么明显。如果你没有时间观念,认为复制文件多久都没关系的话就当笔者什么都没说。 USB 2.0接口的传输速度   可是,买到了一款USB 3.0接口的U盘并非就能好好享受。你还要确认自己的电脑知否支持USB 3.0蓝色接口,两者相配方可达到可观的速度。就像笔者朋友的老爷机,还好不是初代USB接口,否则复制网络电视剧估计得好几个小时。在这里笔者还要给大 家提个醒,原生Windows 7系统并不支持USB 3.0,必须安装驱动程序。Windows 8 8.1 10均可原生支持。 USB 3.0接口的传输速度   可能不少朋友会想,自己平时数码产品又多,各种接口的存储卡或USB口不一致如果又要买SD卡,又要买Micro SD卡,又要买日常使用的U盘,得多累啊。那么笔者就推荐一种比较轻松的方法,那就是组合法。意思就是用大包小的方式,一层套一层来使用。比如我的普通数 码相机使用的是Micro SD卡,那就买一张速度够用的,然后配SD卡套,再配一个USB读卡器,这样的话一个体积的东西就能充当三种用途,妈妈再也不担心我弄丢其中一样。   但是同样也要注意一点,假如你的SD卡和Micro SD卡都是高速卡的话,就不要让读卡器成为瓶颈。笔者手上的这款读卡器算是上一代产物,用了好几年,其实是严重制约了SD卡的速度,只不过一般使用的使用 存放的文件容量都不大,通过古老读卡器复制到电脑峰值也最多20MBps(笔者多希望它坏掉然后换新)。所以笔者建议大家购买读卡器至少都要支持USB 3.0。   基本上现在一般购买移动存储设备(抛开移动SSD不说),只要是支持USB 3.0的设备基本上按照价格往高的走势就是速度越优的指标,主控从低端往高端走。所以在购买的时候,同等容量且同样支持USB 3.0的两款U盘,我们就根据自己需求来买价格适合的就可以了,毕竟所有商品都符合一分钱一分货的道理。另外有一个问题就是,有同学问容量差不多的移动型 SSD跟极速U盘为何会在小而杂的文件传输的时候存在差距?这里笔者再跟大家科普科普。   好几年前我们还在使用的机械硬盘(HDD)由于是机械运动的方式进行存储工作,而高速U盘和SSD就是电子存储器,光电的速度超过机械运动的速度,所以 他们之间速度比较就是天渊之别了。而现在,在SSD和高速U盘之间做比较,为何高速U盘写入大量的小文件(几KB或几十KB)会比SSD慢很多很多倍?理 由就是U盘的体积,发热或颗粒等因素造成它的写入延迟非常高。而SSD虽然体积上略大,但它有实体内存做缓存,通道够多颗粒又好,自然它在大量写入小文件 的时候速度强很多。如果说得太复杂的话大家也可以理解为U盘使用单核单线程的方式做传输,SSD类比的话就是多核多线程。   所以,其实笔者是想说明,U盘仅仅是方便大家带在身上,便携性的优势够强,在连续读写方面甚至不亚于SSD,非常适合用于类似好几十GB的电视剧集的数 据复制。但假如说你平时是比较习惯备份电脑内零碎文档的话,便携性SSD就是你的至佳选择。两者是各有用途,各有优势特征。   至于你说考虑到经济原因,暂时还是使用普通移动硬盘也不是不可以。总之我们日常遇到的使用移动存储设备的疑问与使用建议笔者基本上科普了,如果你再傻乎乎地被商店JS宰了的话,就真没颜了。相关的主题文章:
