Is processor property surplus? Explore CPU is affected to SSD function

2SSD, the function of memory speed happened to overturn sexual change, can use fly to describe, at the same time some closer year come TLC shines put large area to apply, cost is reduced, many SSD products had arrived with HDD do or die when. Mobile phone processor is some closer year high speed grows, have the tendency that has built desktop PC processor greatly, people is very natural think this is current desktop property is surplus be caused by, from Sandy Bridge since, enter 14nm from 32nm besides processor craft, power comsumption gets descendent, people upgrades the motivation of CPU drops gradually, the performance with main reason tired nothing is more... than grows, then property is surplus it is manufacturer in order to not only the method of paralytic user, and because do not have function bottleneck,the user also is met slowly the position that the low speed in accepting a kind of such function to enter increases. From original SATA SSD, arrive again to PCI-Express SSD now M.

2SSD, the function of memory speed happened to overturn sexual change, can use fly to describe, at the same time some closer year come TLC shines put large area to apply, cost is reduced, many SSD products had arrived with HDD do or die when. Opposite at traditional HDD hard disk, SSD has really extremely speedread keeps property, super- low power comsumption is province report, shock-proof fight fall wait for character, these all in all character use a vital part in stamp, just had the flourishing market nowadays, of course SSD wants to replace traditional hard disk in the round, still need to give an user enough material benefit on the price. SSD why fast? 4KB is read it is very important to keep rate aureola of high speed of the top of head, SSD nature is the first selection of user of new clothes machine, because one " fast " word, the user on traditional sense to memory speed " fast " understanding nothing more than read continuously keep rate, this is OK when the big file such as video, picture is transmitted remarkable and spare time. Is if you think carefully,nevertheless your use SSD to be read everyday keep these big files? Actual it is time of to load of content of process of speed of to load of the Windows system time that start, game, application however, actually these projects are 4KB little file greatly read write. Computer memory regards area piece size as us with 4KB know to be in inchoate HDD times already establish 4KB stores for fiducial module, SSD now also continue to use 4KB is modular memory, in short, storage equipment interior is it is area piece to undertake data stores with 4KB. Then data shedding is broken up a certain number of 4KB module, and the data of insufficient 4KB takes up a 4KB stores alone module. After knowing 4KB module, we are OK very easy clear, memory rate is rapid the speed of the fill plan that is 4KB memory module, from the point of this one angle 4KB lasts and read randomly write, basic be the mainest index that measures memory module. No matter be to be in,applied process runs state, the computer is undertaking the bearer of data is made busily, 4KB lasts and read written speed to bring about an user to learn the error that go up in these directly randomly. Odd / double / the data that 4 nucleuses complete imitate checks platform method to introduce us to know SSD is read write memory to need to call CPU line Cheng to finish, especially many 4KB file finds site, read write certainly will to need to drain not little CPU resource, the memory function of such SSD made corresponding impact with the executive ability of CPU, this are ignored very easily by us, because we are puzzled by the false appearance place with CPU surplus property, why can data server delay otherwise machine, because can't bear heavy burden. Store of course the speed of equipment not just with storage equipment (SSD, HDD) about, still have particular concern with CPU, still have the factor such as memory of course. The SSD function difference that 　 of 950 PRO of SamSung of SSD function admiral causes because of the function such as CPU actually us already experience, it is we are alternative only its oversight. The SSD product that stores the manufacturer is released for example, official data is average very beautiful, on one hand these data are to be in the product is measured when the most excellent performance go out (brand-new product) , in process of test of other explicit property, the manufacturer also can use high-powered test platform as far as possible, do not let platform become the bottleneck that SSD function develops, the function e.g. CPU, advocate board memory interface norms. Pu Ke of mainstream SATA 6Gbps SSD is special M6V 　 is nevertheless in real test process, especially the data that each platform give out puts 4K performance in certain difference more or less, this checks the data that platform difference causes to differ namely. The article is in test process to reduce bottleneck as far as possible, used Intel Z170 advocate board the platform with Intel Core I7-6700K, test lieutenant general shuts core amount in group, reduce core frequency to study CPU property is right the influence of SSD memory function, behave for the more comprehensive difference that analyses different SSD additionally, checked us to choose a groovy SATA 6Gbps SSD M6V of Pu Ke spy, with a M.

2950 PRO of SSD admiral SamSung, the capacity all is 256GB. It is 4 core as a result of adoption Core I7-6700K processor, the test is low end of high school of imitate of odd nucleus, double nucleus, 3 nucleuses, 4 nucleuses respectively processor, be opposite to analyse processor frequency at the same time the influence of SSD function, the test was chosen respectively 4.

5GHz, 3.

2GHz, 1.

6GHz and 0.

8GHz quadruplet frequency, and enable all CPU core right now- - 4 nucleuses. Is property surplus? Actual measurement CPU affects above paragraphs introduction to SSD function in, we introduced the main judge standard of SSD function- - 4K is read write, we will use AS SSD Benchmark and CrystalDiskMark below two tools examine respectively the property performance of the SSD below all sorts of different configuration. Tool of ● fiducial test quantifies CPU to affect the AS SSD Benchmark that undertakes above all to check to SSD function, can see the promotion as CPU frequency, the 4K of SSD is read write function to promote gradually, arrive all the time 4 after exceeding frequency.

5GHz, no matter be SATA 6Gbps SSD or M.

2SSD its 4K is read write function to all appear to rise continuously trend. Next CrystalDiskMark checks, the property performance of SSD is mixed basically AS SSD Benchmark is similar, as the frequency promotion of CPU, the 4KB of SSD is read take and write got remarkable promotion. Next we analyse next core amounts to store to SSD again the influence of function, check park of mode general CPU 4.

5GHz, be in respectively Cheng of Cheng of Cheng of odd nucleus single track, odd nucleus crewel, double nucleus crewel, double nucleus 4 lines Cheng, 3 nucleuses 3 lines Cheng, 3 nucleuses 4 lines Cheng, 4 nucleuses check 6 lines Cheng, 4 nucleuses below condition of 8 lines Cheng the 4K of SSD is read. AS SSD Benchmark checks, no matter be the growth of the growth of CPU core amount or line Cheng amount, its 4K reads tie-in SSD write function to do not have apparent change. Next CrystalDiskMark checks, the property performance of SSD is mixed likewise AS SSD Benchmark is similar, the addition of CPU core amount and line Cheng amount is not right of SSD read write function to cause an effect. SSD of much nucleus no use is read write function to concern little file of 4KB of 　 ● actual measurement to read with frequency only keep rate we see CPU frequency read the rate that keeps 4KB little file to affect to SSD finally again, test only with 4 nucleuses 1.

6GHz and 4.

5GHz configures achievement contrast two kinds, and open CPU exceeds line Cheng technology. To avoid function bottleneck, the test serves as with M6V SATA 6Gbps SSD of Pu Ke spy fiducial, with SamSung M.

2SSD 950 PRO copies 4KB little file each other, use Fastcopy record is read write time and read keep rate. (test file bag includes documentation of 20000 4KB TXT) 1.

The SATA 6Gbps SSD below 6GHz is read on average take rate 4.

The SATA 6Gbps SSD below 5GHz reads the SSD that takes rate to undertake above all on average take a test, CPU 1.

Below 6GHz frequency, read on average take rate for 4.

82MB/s, frequency promotion comes 4.

5GHz hind is read on average take rate to promote to 13.

6MB/s, function promotes extent to be as high as 182% , the difference between corresponding CPU frequency is 181% , agree basically. 1.

The M6V SSD below 6GHz writes rate 　 on average 4.

The M6V SSD below 5GHz keeps rate on average next SSD writes a test, CPU 1.

Below 6GHz frequency, read on average take rate for 4.

36MB/s, frequency promotion comes 4.

5GHz hind is read on average take rate to promote to 11.

2MB/s, function promotes extent to be as high as 157% , the difference between corresponding CPU frequency is 181% , function promotes extent and frequency difference to have certain difference. Final conclusion 　 CPU- - SSD function depends on a test to come here come to an end, pure will talk with SSD, CPU property is surplus too cursory, although at present CPU has entered 14nm period, no matter be function and power comsumption reached new height, but from it is we can see test data, SSD 4K is read write function to have serious dependence to CPU, although exceed frequency,come 4.

The SSD of Core I7-6700K platform of 5GHz still is maintaining taller read write speed to increase a current, when appearing as to bottleneck, current processor is afraid cannot achieve such odd nucleus performance. CPU reads the influence that keeps property to SSD 4K, the multi-line Cheng character that because current hardware is designed,cannot use CPU very well with the operating system on one hand will send the potential of disinter SSD, 4K is small on the other hand of the file read write involve voluminous data to take location, read the operation that take and keeps, raised taller requirement naturally to CPU, even if SSD just also offerred faster data passageway form, but data job is measured and won't change, so future wants to obtain better data storage experience, besides function of ceaseless promotion SSD, also did not ignore the development of the function of CPU and multi-line Cheng please. The article arrives here, do not know whether the reader discovers, be in before each are big when the website tastes a hair newly to evaluate, disparate 4K appears to read when we always can discover function of SSD of each big media test keep performance data, if,sentence even two products, different place brings about the platform that this basically checks as a result of the product. Of course besides norms of SSD itself, CPU, play of influence SSD function still has a lot of factors, be like advocate board the play that the metropolis such as sequential of frequency of SATA controller, CPU PCI-E controller, memory affects SSD performance.
