Tiền hạn hẹp quá bác à,
mà mình cũng k biết có hỗ trợ PCIe k nữa, mua dòng PCIe về mà dùng như SATA3 thì phí quá
About M.2 SSD upgrade:
I tried out the Samsung SM951 512 GB AHCI Version which has M-Key connector like the mainboard (see picture). The SSD is able to do PCIe 3.0 (northbridge) and PCIe 2.0 (southbridge). But the SSD was not recognized.
That means the Y700-15ACZ has no PCIe Lanes connected to its M.2 port! So be careful. You can only use SATA SSD models there. Those have normally Key M+B coding. Lenovo soldered wrong M.2 port to the mainboard (maybe to save money as it uses the same on Intel versions which support PCIe). Correct is only Key M+B port (shame Lenovo engineers).
After searching around I think the best SSD you can put in here is the Samsung EVO 850 512 GB. It seems to be the fastest, has best lifetime, good price, good tools and comes with 5 years warranty. You can also choose smaller versions of that but write performance will be much slower than.
