Intel Rapid Storage Technology and effect on ssd speed

Good morning At least it is in my country.....
I am selling my P150EM/NP9150 , and one of the prerequisites on the buyers behalf was that the OS stayed installed with stable drivers. He had heard so much of the bad things on the 7970m ++ that he didn't want the initial hassle. Ok, so I start cleaning out my files and unnecessary applications, drivers and...... whooops, Wait a minute there ! As I am cleaning out drivers, I always do some simple tests to see whether I have disrupted the balance of the force or whatever.
In the case of the Intel RST(Rapid Storage Technology) driver package, something went terribly wrong.... at least performance - wise.
Now look, I have scoured the net earlier, and I have implemented every ssd tweak from here to eternity to max my performance. But UNINSTALLING Intel Rapid Storage Technology (NOT rapid start tech) cut my IOPS in half.
I couldn't understand it really. I am using the 6Gb/s port for my OS Samsung 840 pro, and even though this driver is supposed to work in both AHCI and RAID mode, everybody was saying that this should have no effect on the disk performance. The package DOES have Smart ResponseTechnology though, but I haven't checked into this( Shipping the laptop today).
Even worse was the fact that after UNinstalling RST I couldn't REinstall it. No way. I tried the "updated" driver thread here on the forum, but that driver dated back to 2/3/2012, and worse of the matter - it gave me a black screen on reboot after install. After scouring the net once again, Intel not providing a god damn thing said to be compatible with the series 7 mobile chipset, I switched my search to the Sager NP9150 and found neatly hidden away a working version
Sager NP9150 Intel RST Driver 11.0.0.1032 for Windows 7 Windows 7 driver download - Windows 7 Download
Suffice to say, my IOPS on simple performance testing again now (almost) reaches the advertized speeds for both my Samsung drives.

SO, either I am very special( which I doubt) or these drivers(on this system) DO in fact play a big role for storage solutions. Why you cant find a single phrase concerning the matter on NBR is kind of puzzling, as people do seem to want to optimize their performance ;-)

 

I don't understand your problem.
Why would you want to uninstall Intel RST? It's there to manage the SATA interface in Intel's chipsets.

It's similar to a situation, where you would uninstall the AMD 7970M driver and then brag that the card is slow on generic VGA drivers.

Nobody discusses the need for RST anywhere on NBR, because everyone knows that it's one of essential drivers/software in an Intel based system.

 

xDD Intel RST is package ,if you dont have RAID in your laptop, all you need from Intel RST package for your SSD is x64 driver for SATA AHCI Controller. ,
latest version Intel RST 12.7.2.1000 WHQL

 

Since Windows has its own drivers for managing AHCI, it's up to you to keep it or lose it. Some have reported better boot times with it, and some say their boot times were better off without it.

 

You should really wipe the drive and install the OS fresh and then install the drivers if required before you sell a laptop.

 

@Marecki_clf, Prostar told everything. Some people say that microsoft's driver is better. Perhaps they compared to a way older v. 10 driver, but pay attention that some newer versions have it disadvantages too.

I personally use 11.7

 

OP, I strongly suggest you do this. Reformat the drive (not Quick Format), and do a clean install.

The new buyer may be able to recover your old data using the method you suggest, as well as run into other driver hangups that you may have caused.

On topic: I am using the latest RST and latest Samsung Magician and have normal speeds for my Samsung 830.

 

I see that there was some editing of the posts here ;-) I understand completely, It just rubs me the wrong way when people are just on these forums to criticize post formulation or talk smack...
Anyway, for performance I have difficulty in seeing how one would get more speed or responsiveness from just the Windows drivers.
Also, I did do a clean install before shipping the laptop as per your recommendations. Actually it was the only way I could get Intel rst working again.

 

By the way, I tried installing just the ahci sata driver and leaving the rest out, but on reboot the system would not boot to Windows. I totally cleaned out everything rst related, installed just the lone driver. It did not work for me. Windows sata driver would work, but with severely degraded performance.

 

What is your chipset driver version installed?

 

It's not entirely contrasting in theory when video card driver updates provide added performance in games. I don't know the underlying coding reasons as to why one driver works better than another on such a case by case basis.

Did you install the chipset driver first?

 

Yes, Installed the chipset driver first. Now I have a new system of course, but I used the Intel driver update utility a couple of times for the chipset while I had the p150em. So it would be the install - order messing up the Intel configuration you mean? Or a correspondance in versions ?
For sure I am never going to uninstall rapid storage technology again without a good reason ;-)
