The SSD hard disk for the NVMe (Non-Volatile Memory Express) protocol has long been saliva for a long time. And since the introduction of PCI-E channel-based SSDs by Intel and the addition of three sticks of SM series, before the series of SSDs are used, it is theoretically necessary to explode, and it will be possible to grow plants in minutes. So when it comes to its own desktop, this has long been classified as an option. It was purchased recently because of budgetary reasons. So, there is the following assessment.
PS: Tested as OEM SM961-0000 version, of which 0000 is the manufacturer's logo. If it is not the 0000 number, it is the version of each manufacturer, you need to pay attention to notebook compatibility.
PS: Just buy it. Anyway, I just bought it. . . The capacity is set by itself, and the greater the capacity, the faster. . .
Samsung SM961 512GB M.2 NGFF PCIe Gen 3.0 x4, NVME Solid State Drive (SSD), Genuine Eluktronics OEM Eluktro Pro-X Part Number MZVKW512HMJP-00000289.95 USD Speeding Car. . . US Amazon Direct Links II. SSD-related knowledge and M.2 interface knowledge SSD has been out for a long time. I remember that one of the earliest strong SSDs I used was Plextor's M5S. At the time, it was bought for friends. When I bought it, I took the SATA interface, and the read/write performance was 450M/s. It made me think, I can't do it so fast. Since that time, even if the budget is limited to 128GB SSDs, I would recommend that friends save money on SSDs. After all, the senses are greatly enhanced.
Of course, before that, HDDs, excluding raids, rarely run full SATA bandwidth. But with the SSD it runs full minutes. Naturally there will be more performance protocols, based on the PCI-E protocol hard disk. (Although it has been out for a long time, but the average consumer can not touch, can only look up)
SSDs based on the PCI-E protocol are also divided, because the channels they go are PCI-E*2 and PCI-E*4. Among them, in the actual design of PCI-E*2, the limit speed that can be achieved can only have 700M/S, although it is better than SATA, but the promotion is not obvious, and it is actually used as SATA. However, the PCI-E*4 channel has a bandwidth of 32G/S on a minute basis, and it can theoretically achieve a read/write speed of 3.2G/S. (Of course, the recent intel out of optane hard drive is a thing that makes me grow grass.)
Regarding the M.2 interface, not every M.2 hard disk is actually a PCE-E channel. Because according to the M.2 interface, it is actually designed for smaller sized SSDs, which can achieve a smaller size in designing notebooks and the like, thereby bringing about various improvements. M.2 interface is divided into B-key and M-key: (borrow network diagram)
B-key:
M-key:
1.M key interface high-end solid state drive, take the PCI-Ex4 channel
2. B&M key interface SSD, take PCI-E x2 channel
3. B & M key interface SSD, take the SATA channel
And our SM961 on the M-key interface, SO, the speed of natural bombing.
SM961 parameters: 256GB of which is a performance on a level, but also with the 512 1tb this local tyrants to buy the version of the performance of a small gap between the capacity, reeling or 256GB it. . .
Appearance: It is exactly like this, in fact, very small and small, M.2 is also designed to reduce the volume to meet the needs of the notebook, MACbook pro all on the M.2, and Sao's fried up. . .
Look at the size of the comparison: positive (red RMB just hope that everyone is booming in the new year ha ~ ~ give me a point G coin just fine)
The opposite: bright
Oblique 45 degrees: This angle can be seen to be really small and thin. . .
In fact, the above kraft paper as a test, of course, to tear off, take a look at the main control and memory particles ah, no, continue on the memory particles and master map:
Memory particles: k9ukgy8sce, MLC? Do not tangled, anyway, there are few SLC. . . Think about note7 was blown up last year, stick just rely on memory LCD and so on can actually earn so much money. . . Hey. . . Silent ah. . .
The master: This master is the protagonist of so many speeds. Really cattle B. . .
The comparison between the master size and the one-dollar coin is actually very small. . . .
Thickness: This thickness should be a 1mm thick PCB. Use this thickness carefully. The mechanical strength is not as high as 1.6mm; and please note that the height of the memory particles is inconsistent with the height of the master control. It is necessary to pay attention to the heat sink.
Motherboard: ASUS M8G
CPU:z
Memory: Corsair 8GB*2@3200MHz
Power: Customized
Cooling: Corsair H100i
Firmware version: CXZ7300Q (It looks like there is another version update. I don't know if it is updated...)
Two on the machine map. . .
This is the test data of AS SSD: Remember to download the driver installation from Samsung's official website. Otherwise, the running points are not normal. WIN7 requires special installation tools. 
Actual use test:
I installed the system, copied 30GB of data, because my own hard disk, only copy the speed to 450M / s, the hard drive can not meet the SM961's copy speed, and the speed is stable. . .
In addition to boot fast, or boot fast. Install the system fast, copy the data fast, all kinds of fast. . . .
to sum upAdvantages: very fast, small, easy to install
Disadvantages: Drive installation trouble, the price is not low, 4K read and write meters have significantly improved, the temperature also needs to be controlled. . .
Finally, in the new 2017, I wish you all a Happy New Year, and the speed of making money is the same as the continuous reading and writing speed of 961, flying up and flying. . .Communication Backup Lithium Battery System
