Having recently purchased a Samsung SM961 PCIe MVMe SSD I was shocked to find that my write speeds were only 350MB/s. I have the SM961 installed in a Lycom DT-129 PCIe card but I only have a x4 PCIe 2.0 slot on my current motherboard. When I purchased the SM961 I was aware that my speeds would be impacted by the PCIe 2.0 slot but did not anticipate such poor Write speeds. With it being an OEM product the SM961 also has no drivers supplied and at the time of writing this article Samsung and no other PC manufacturers appear to have posted optimised drivers. I was aware that Windows 10 provides native NVMe driver support and expected reasonable performance from them.
Unhappy with the Write speeds I started to experiment and eventually found that if I disable windows write cache buffer flush in Device Manager then my Write speeds jump to just over 800MB/s which I can happily live with.
Here are my findings:
I tested with write caching and write cache buffer flushing disabled
I then tested with write caching enabled and write-cache buffer flushing disabled.
I would be interested to hear for you so please do post your feedback or questions.

3CX Version 14 Service Pack 3 seems to include/use very old and insecure versions of OpenSSL 1.0.1e (11th February 2013) and 1.0.1g (5th June 2014).
More info about the locations is below:
C:\Program Files\3CX Phone System\Instance1\Bin\libeay32.dll

1.0.1e (11 Feb 2013)
OpenSSL 1.0.1t is the latest release and resolves a number of serious vulnerabilities
This means that 3CX V14 Service Pack 3 is likely to be vulnerable to all of the documented vulnerabilities prior to the 1.0.1t OpenSSL release. Using an IPS firewall may help to reduce the risk to your system until an updated version of OpenSSL is integrated into 3CX.Follow @aid_in_it
RC4 cipher suite is still enabled in Abyss Web Server X2 (Version 220.127.116.11) that is supplied with 3CX Version 14 Service Pack 3.
