Usually disabling the write-cache buffer flushing (=checking the option) boosts the write performance significantly. Try it and compare the benchmark results!

Hey Fernando! As we expected, I get better benchmark results by disabling write-cache buffer flushing... I have a question for you, again touching on the ASUS provided IRST drivers... As you have seen with the additional installation files included are "rstcli.exe" & "rstcli64.exe" I did some research and now I am aware about Intel® RST CLI (Command Line Interface) Which I did not know about before... Here's the documentation I found > LINK < And here's what I find on the Intel® Download Center > LINK < My question to you is if you have any experience with RST CLI? As to its use and implementation? I'm interested mainly because I might update my IRST drivers and I can only conclude that ASUS included the additional installation files with a specific purpose, I want to update as correctly as possible... I have already experienced the side-effects with poor performance and would like to avoid messing things up! Now we can agree that I'm not running RAID so would you have an idea as to the intended setup process of the additional ASUS IRST files? You see I have my doubts that in my case it might not be as simple as just updating IRST drivers from Device Manger... Do I need to use the "rstcli64.exe" lets say booting to WinRE or PE since I'm running Win8.1 in UEFI Mode? Or possibly use DISM to add the drivers? I would appreciate any advice you might have on this matter!!! Thx!!!

Here is my comment:
All these tools from ASUS and Intel are using the so-called Intel(R) Smart Response Technology, which requires either a combination of a HDD (as system drive) and an SSD (just for data caching) or an SSHD, which is a hybrid drive and actually built into many notebooks.

I understand from what you had previously mentioned along with my research detailed about Intel® Smart Response... Please forgive my confusion... Basically, the majority of the additional Installation files included in the ASUS IRST drivers, DON'T APPLY for my particular variant of S451LN... Correct?
Since as far as I know I don't have a SSHD or additional SSD that's built-in... My variant is the i5-4200U + 1 TB 5400RPM SATA HDD... Here's the link for the available options > LINK < showing optional HDD configurations... some added with an 8 GB SSD (SSHD?)
So what would be your "Recommendation" for updating my IRST drivers? From Device Manager using Intel® downloaded drivers like normal? Lastly, should I update to the latest IRST v12.8.x... v12.9.x... or can I try any of the v13.x series? Given that I have an 8 Series Chipset Family... My concern is the Hardware ID's I have show this ->

SATA AHCI Controller: PCI\VEN_8086&DEV_9C03&SUBSYS_139D1043&REV_04\3&11583659&1&FA... The DEV starts with "9"

I'm having some driver issues for some reason... Since I have Haswell-ULT IMC + Lynx Point-LP (Premium SKU)... There is no HM8x/QM8x... How can I be sure if any IRST v13.x are supported? Or if I need the "Modified" drivers? All my confusion is caused because from what I think I know is the "9" in the beginning of all my DEV_ID's points to X9x Chipsets... Or am I wrong?

***UPDATE***

I did more research in to RST CLI and also tried ASUS online support chat to see what their explanation was about the added files... etc... ASUS at first didn't know what I was talking about.... They insisted there was only a Setup.exe and that was all I had to run... After I further explained... ASUS told me that I only had to run rstcli64.exe from an Admin Command Prompt... Which I later discovered doesn't install anything... Here's info from the README:

************************************************************
* 1. OVERVIEW
************************************************************

Intel(R) Rapid Storage Technology (Intel(R) RST) for CLI is
a command line utility used to perform basic RAID operations
on RAID-enabled systems. Intel(R) RST for CLI supports RAID 0,
RAID 1, RAID 5 and RAID 10 volumes.
Intel(R) RST for CLI supports the following functionality:
- Creating RAID volumes including recovery volumes and arrays
using the Create mode
- Viewing properties of disks, volumes, arrays, and controllers
using the Information mode
- Managing RAID volumes, arrays, and disks using the Manage mode
- Modifying existing volumes using the Modify mode
- Accelerating a disk or volume with a specified SSD using
the Accelerate mode

Here's what it shows by running "rstcli64.exe -I":
Since I haven't dealt much with RAID... I assume that RST CLI is basically the same thing as pressing "Ctrl+I" when booting, right? Now the image above says I do support RAID0,1,5 & 10... Which BTW also matches what the BIOS image shows in SATA Configuration with AMIBCP... That RAID0 & 1 are "Enabled" BUT as you have so clearly pointed out, that's if I had an HDD+SSD or SSHD... I might not be understanding all this or I might just be blind... But how does it apply to my case either with the factory HDD or my SSD??? Regardless of which I use its still a "Single" drive setup... I'm getting really lost and confused....
