Limited by the size of the computer desk and the chassis, the space reserved for the main memory of the landlord's main machine remains only the M.2 (NGFF) slot on the motherboard. Therefore, choosing a high-capacity M.2 SSD is the most convenient solution. Since the landlord needs more capacity than the limit speed, the capacity/price ratio is the only decisive selection criterion. Although the product performance of PCI-E channel is powerful, the high-capacity model is too expensive, so the 1TB model of SATA channel is the ideal choice.
After some screening, a Guangwei 1TB M.2 SSD was reflected in the landlord's eyes. The SSD is priced at 1,050 yuan, according to previous "on the car" friends said that it uses SMI EN2246 master + Hynix MLC NAND chip. Taking into account the price of 1,000 yuan and MLC chip, the landlord decisively on the train to see if you can safely get off?
First, appearance analysis
The packaging box is a transparent plastic box. It can be seen that there is sponge protection around the SSD body. Although it is simple, it has obvious protection.
This is the SSD body. Have to say, M.2 2260 SSD is really small, about the size of only two SD cards. The figure is compared with a one dollar coin. (Tucao, there are two misspellings on the Guangwei SSD sticker...)
The back of the SSD. Because it is a 1TB model, there are also two Flash chips on the back. 256G, 128G models this side should be no chip, 512G may not be.
Two stickers on the back of the chip are affixed with stickers, but it can be seen that Sk.hynix is ​​engraved on the surface of Flash. The preliminary judgment is the positive Hynix MLC. Taking into account the warranty factor, the landlord did not tear the sticker.
This is an installed effect. The M.2 installation location is between two PCI-E x16 slots.
After plugging in the graphics card, the SSD disappeared... In other words, this location should be very bad for heat dissipation.
Second, the performance of the test
This is the main information of the hard disk. Firmware version V1AB02.
In terms of performance, I also learned that Guangwei's 1T SSD is very general in terms of writing. Baidu Tuba old drivers have done a lot of research on this
This is the AS SSD data tested by the landlord. Sure enough, in terms of writing, 1TB models can not play the full performance of the master. However, the overall performance is still relatively OK, can reach 843 points, used as storage warehouse tray no pear.
The actual copy can reach 250MB/s, which can basically meet the storage disk write requirements.
In terms of temperature performance, as mentioned earlier, the position between these PCI-E slots is destined to be very poor. The temperature reaches 57 degrees. It can be seen that the 2.5-inch SSD has a much better heat dissipation performance.
Third, summary and commentsIn general, if the landlord can use the SSD smoothly for 3-5 years without "turning over", then the price of 1050 yuan and the point of view of the SK.hynix positive MLC are definitely worthwhile. However, there is indeed a certain shortcoming in performance, SMI's EN2246 master full speed can reach 380MB / s write speed, so Guangwei 1TB SSD has a great room for performance improvement.
advantage:
Low price
SK.hynix positive film MLC;
2260 specification compatibility is better;
Disadvantages:
Write performance failed to exert its master control strength;
There is an issue of English spelling mistakes such as "chat".
