如果你更換筆電的M.2 SSD，你需要確認主機板實體路線和BIOS有支援。
if you want to change M.2 SSD on your laptop, you need to make sure your hardware and BIOS support it
Upgrade List...
SSD: samsung 950 PRO 256G
Memory: Kingston DDR4 2133 8G
Simple PCIe Circuit pin definition:
PCI-e X1: PERp0, PERn0, PETp0, PETn0 (pin49, 47, 43, 41)
PCI-e X2: PERp0~1, PERn0~1, PETp0~1, PETn0~1
PCI-e X4: PERp0~3, PERn0~3, PETp0~3, PETn0~3
參照上面寫的 PCI-e X4腳位定義，確認黑色的插座上有實質的線路接到PCIe。
Refer PCI-e X4 circuit pin definition, Make sure the black socket has actual circuit connection to PCIe.
如下圖所示，確定VN7-592G是 PCIe X4 SSD而且利用PEDET(pin 69)偵測可兼容SATA SSD。
As below picture, you can see that VN7-592G has supports PCIe X4 SSD and SATA SSD by PEDET (pin69) detecting circuit.
如下圖所示，原本的Samsung MZNLF128HCHP 128GB PEDET 連接到GND (SATA mode)
As below picture, The original SSD - Samsung MZNLF128HCHP 128GB PEDET is connet to GND (SATA mode)
Step 1:
Make sure your BIOS version is high than 1.03
Step 2:
Change Boot mode to Legacy
Step 3:
Install OS as any you want.
Performance Result: Samsung 950 PRO 256G (NVMe PCIe X4)
AS SSD benchmark: Read:1945.98 MB/s; Write:897.03 MB/s
CrystalDiskMark: Read:2234 MB/s; Write:958.1 MB/s

2016/03/13: NVMe SSD 溫度測試及改善
NVMe SSD Temperature test and improve.
未改善前 (45C ~ 70C 之間)
Before improve M.2 NVMe Samsung 950 PRO 256G temperature ( almost 45C - 70C):
Samsung 950 PRO 臨界溫度在75度c，過熱即降頻，同時讀取效能亦跟著下降，就像下圖橘色部份(參考至Lini PC)
Samsung 950 PRO thermal threshold: 75C, overheating: performance fall down. Like below orange partial(Refer from Lini PC)
我想用鍵盤做散熱器，但是 M.2 SSD 和 keyboard之間有間隙 (大約 2.4mm)
I want to use Keyboard as cooler, but there are some gap between M.2 SSD and keyboard (approximate 2.4 mm).
解決方法，上網買 3mm 的導熱矽膠。
Thermal Solution: i get the thermal pad from Ruten.
Thermal Pad: TG-X Ultra Soft Thermal Pad.
Thickness: 3mm (2.4~3mm is OK)
Thermal Conductivity: 12 W / mK
如下圖所示，把導熱矽膠放在950 PRO的晶片上
Now put the thermal pad on the 950 PRO chip as below picture.
改善後的結果，31度C ~ 52度C 之間
Result: almost 31C - 52C
