必須密切注意到硬體 DIY 的朋友會對 M.2 SSD 有說, 如果你把前兩年, 這是一個珍貴的東西, 只是 256 的 G M.2 SSD 至少有超過 1000 人民幣, 一般人買不起! 但這是不同于以往, 隨著快閃記憶體技術的不斷進步, 很多使用 M.2 介面 SSD 價格已經降到普通使用者可仍可接受水準, such as the Intel 600P series, GALAXY series of armored warfare.
This period the author specially for three kinds of SSD products on the market (respectively: support NVME protocol PCI-E M.2 SSD go 3.0x4 channel, SATA channel M.2 SSD and general SATA SSD, and the three, the price is quite) in feeling really have so much difference between the actual experience?
The above said, the author specially for three kinds of SSD products on the market, which is to support the NVME protocol PCI-E 3.0x4 channel 256G M.2 SSD GALAXY cartel, SATA channel M.2 SSD Plextor M6G 256G, Adata SU800 SSD and general SATA 256G; of course, with strict and pragmatic spirit, although we find the only true white woman to do the test of practical experience, but still it is necessary to use the theoretical results to you Kanguan pay a bottom.
Gossip is not much said that the test platform specifications are as follows:
Test note: this test is designed to other hardware platforms are unchanged in the case mentioned above three SSD clones on the same system for testing and experience.
Results are as follows:
As you can see, the NVME protocol support go PCI-E 3.0x4 channel GALAXY cartel 256G scores, continuous reading were broken 1GB/s, 4K read and write the way ahead, and low delay.
Above to go SATA channel SSD M.2 Plextor 256G M6G results, continuous reading and writing about 500MB/s (not to break the SATA 3 limit), 4K read and write a lot less than the former, the delay is slightly higher.
The last figure for ordinary SATA SSD Adata SU800 256G scores, continuous reading and writing the same is about 500MB/s, 4K read and write even more than take the SATA channel M.2 SSD is also a slightly lower delay. In general, but the two are due to go after the SATA channel, the speed can be said to be not much difference between. As for the first performance is beyond all doubt the way ahead.
The conclusion is that the light running performance, support NVME protocol and PCI-E 3.0x4 channel GALAXY 256G cartel is undoubtedly the best, so the actual experience of whether this is true? Let's listen to my sisters.
In using our test platform on the tall, the company from many sister paper randomly grabbed three little sister paper, Hong kong! They really are utterly ignorant of the PC hardware.
首先, in order to facilitate the test, the author gave three SSD of SATA Adata SU800 SSD encoding, 256G number of ordinary 1 M.2 SSD Plextor M6G 256G SATA channel number is 2, support the NVME protocol and GALAXY 256G go cartel number PCI-E 3.0x4 channel 3.
The first is the experience of our group of lovely girl video, sister to see a gossip ("science and technology" the gossip buddy should be no stranger!
She, after the experience of the three SSD is so said: I personally feel that the second to me the best feeling, the first is to open the web faster than the first speed (web speed and speed is not related to the well fed?) , but the speed of the picture into the PS but feel slower than the first paragraph, the third paragraph gives the feeling is to open the PPT faster than second models a little slower, so I personally prefer the second paragraph. But the first second models give people feel almost.
Second experience is our fashion network hearty sister paper Wu disturb: first of all, I personally feel children's first and most slowly, third words to second people feel the same, especially the third import pictures to PS when a particularly fast speed, PPT open faster; in addition, by virtue of a woman the sixth sense I feel third more expensive! Your sixth sense is so true! Sweat ~)
The last experience is our mutual Entertainment Group C.C sister, “ the slowest of the second models! The first and third to give people feel almost, but the overall feeling is very fast, faster than my home computer! ” (laughs) the author: “ why do you think the second is the slowest? ” “ just think of the second paragraph into the picture to the speed of the PS is particularly slow! ” (laughs again.)
Comprehensive above the younger sister paper, the author summed up a bit, the Eight Diagrams elder sister bias second, Wu disturb the third models, C.C is that the first third are good! 所以, the actual result is really a little bit to support the NVME protocol and PCI-E 3.0x4 channel GALAXY 256G cartel!
答案是肯定的, our students meticulous science spirit, the author also makes pinch table test, at the same time through import 50 pictures to PS results are as follows: the first time 58.02 seconds, second time 58.95 seconds, third took 54.46 seconds. Can be responsible to tell you, to support the NVME protocol and take the 3.0x4 M.2 channel SSD PCI-E is indeed faster! (so that children feel Wu disturb is still pretty accurate!)
I said so much, I just want to tell you that in the three mainstream SSD price of similar year, if your motherboard with M.2 interface to support NVME protocol, then in time to buy a new SSD, you can choose a NVME protocol support and take the PCIe3.0x4 channel SSD don't buy what SATA SSD! After all, the era of progress, SATA interface will eventually become the past, just as long as the IDE interface has gone......
