@Master O:
When you want to update the Intel RST/RST(e) driver manually, you have to run the Device Manager, expand the "IDE ATA/ATAPI Controllers" (for Intel AHCI users) resp. the ""Storage Controllers" (for Intel RAID users) section, do a right-click onto the listed AHCI resp. RAID Controller and choose the option "Update Driver software".
The rest of your procedure scheme is ok.

are these SHA-1 hashes below correct for the above driver?
I don't want to install a corrupted driver, after all...

@PitKoz:
Unfortunately your advice is not valid for users, whose on-board Intel SATA Controller is running in AHCI mode. Please look into >this< answer I gave to Master O.

@Zetren:
Here is my comment:

1. To be able to evaluate the quality of a certain driver it is not enough to look at the benchmark results. The stability of the system is important just as well.
2. The Intel RST(e) driver v11.7.0.1013 dated 11/19/2012 was the first, whereas the v11.7.4.1001 dated 03/05/2013 was the latest driver of the v11.7 development branch. Since each new development branch starts with new features and a lot of bugs, it is hard to believe,
   a) that the first version has already been the best of a certain development branch and
   b) that Intel had continued nevertheless the development and the release of newer/better v11.7 series drivers for several months.
3. If you want to compare the speed of 2 different drivers, you have to compare under similar conditions the performance of the related HDD/SSD, which is managed by the driver resp. its Controller, and not to compare the speed of your complete PC.

@Dagal:
You should better ask Intel than me.
By the way:
1. You can get any of the much newer Intel RST(e)/RST drivers properly installed by using either the mod+signed variant or pressing the "Have Disk" button, navigating to the file named iaAHCIC.inf and choosing the oldest of the listed Controllers.
2. The only v13 platform Intel RST(e) drivers, which natively support the DEV_8D02 Intel SATA AHCI Controller, are the v13.1 series ones (latest: v13.1.0.1058 dated 05/02/2014).
3. It is an illusion to believe, that the newest Intel AHCI drivers are the best even for older Intel chipsets. Sometimes very old drivers, which were developed earlier than the related chipset, are the best (look >here<).

@dagal:
Yes, but I bet, that you will be disappointed regarding the performance of the v16 and v17 platform Intel RST drivers.
