Windows 10: Intel RST drivers for SSD - when to use?

Hi I am trying to understand if the Intel RST driver is necessary or not, or if only required for particular setups. I have 2 computers:1)Desktop - boot drive: SATA 3 SSD (Windows and applications), and aSATA 3 HDD for document storage. 2)Laptop M.2 SATA 3 Micron SSD (PCIe NVMe). Do I need the RST / RST Optane driver for either or both?Thanks(Winver: 21H1)

Intel RST service is not running

Hi,

Thank you for writing to Microsoft Community Forums.

The Intel RST service is for the Intel Rapid Storage Driver. The Intel Rapid Storage Driver provides speed for data transfer and improves the performance for SATA drives or PCIe drives.

• What is the make and model of the computer and motherboard?
  

You can follow the methods mentioned below and check if that helps:

Method 1: Changing the startup type for Service

You can try changing the startup type for the Intel RST service and check if that makes a difference. Please refer the steps mentioned below:

1. Press and hold Windows key + R, to open
   Run dialog box.
   
2. Type serivces.msc and click on
   OK.
   
3. Now, scroll down, look for Intel RST service, right click on it and click on
   Properties.
   
4. Now, under startup type select Automatic from the drop down menu.
   
5. Click on Apply and OK.
   

Method 2: Updating the drivers manually

You can try downloading the latest version of Intel Rapid Storage Driver from the

Intel Website and check if that helps. However, I would suggest checking with the motherboard manufacturer website as well.

If you are using RAID configuration, I suggest you to post your query in

TechNet forums, where we have support professionals who are well equipped with the knowledge on RAID configuration.

intel rst driver

i dont have win 10 installed so cannot try... does intel rst works? i have found that it is much faster then MS default drivers with 97 boards with win 8.1. Not so much in benchmarks, but in practice win 8.1 boots much faster with iastora.sys then benchmarks
difference suggests.

 

Intel RST data at risk warning - how to resolve? (SSD & Intel Optane)

I have an Acer Aspire 5 (A515-51G). (Specs: i5-8250u; 4gb DDR and 16gb Intel Optane memory). I replaced the mechanical HDD with a 240gb Sandisk SSD and did a fresh install of Windows 10 home (ver 20H2).

I updated the drivers from the Acer website, and after it installed the Intel RST (Rapid Storage Technology) I got a ‘warning’ that data may be at risk.
Is this a genuine error?

It shows the SATA SSD as ok, however the PCIe NVMe SSD (13gb) Controller 3, Port 0 is ‘’offline’’. This also has an option to ‘’clear metadata’’.

I noticed in my Device Manger that under ‘’Other Devices” PCI Memory Controller and SM Bus Controller both have a yellow triangle with ! mark.

I googled this an found there is an Acer hotfix IRST (Intel® Rapid Storage Technology) Driver Hot Fix 16.7.8.1024

Any idea how to resolve this? I am assuming this PCIe NVMe SSD (13gb) has something to do with Intel Optane.

1. should I uninstall RST and replace it with an Optane driver?
2. remove RST altogether?
3. install driver hotfix no sure this is the solution?
4. setting in BIOS?
5. Clean Win10 install?

Any other suggestions appreciated?

Thanks
