build an hybrid disk

On my laptop I have one spindle 750GB boot disk and one 32GB ssd disk Liteonit .

The 32GB disk is unused and i wish to use it building an hybrid disk with the boot spindle 750GB+32gbSSD .

Questions:

Is it possible?

Where can i find the procedure?

Most important is I must preserve the OS windows 7 boot without reinstall all windows OS.

Browsing the forum can t find this information.

Thanks so much.

Hello Roby198,

 

 

I understand you would like to build a hybrid disk with your 750GB drive and the 32GB SSD.

 

 

I will be more than glad to assist you with this inquiry.

 

 

It is possible to combine a SSD and a mechanical hard drive on a RAID volume, but not with the specific settings you have in the computer. The SATA mode on your computer is set to AHCI so it is not currently possible to create RAID volumes on your system. If you want to create a RAID volume in your computer it will be required to change SATA mode to RAID in the BIOS and then reinstall Windows* from scratch.

 

 

Bear in mind that by combining a mechanical hard drive and a SSD on a RAID volume the SSD will be forced to work at the speed of the mechanical hard drive. Probably the maximum size of the volume you will get would be 60GB.

 

 

Let me know if you have or not any other inquiry.

 

 

Regards,

So...need to reinstall windows and build a raid ...ok. But i missing you about the final result.

I mean to buil a sshd (hybrid disk ) that use the spindle 750gb and add the fast ssd 32gb not.in.raid but the 32gb is used to host more accessed files .

Like a cache. The result is not a raid is a 750gb disk that transparently to the user it use rely the 32gb ssd to speed up the IO.

Never hear the sshd technology?

Right, you are talking about using Intel SRT. You install Windows to HDD and then accelerate its performance by setting up the SSD as a high-speed cache using this technology.

I have a couple of older NUCs (WY and RY models) running using Intel SRT. In my case, since I had much larger SSDs, I used part of SSD as high-speed cache for HDD and part as Windows System Drive. There is an article about how I did this in the documents section of this forum.

I would add that, in order to preserve the OS installation on the HDD, you must have configured for RAID (In the BIOS) *before* you installed the OS.

HI Scott,

thanks to confirm my doubts.

So , need to configure raid in the bios, this need reinstall OS, then can use the RST technology.

At this point i think to abandon this idea and consider to buy a SSHD drive that is hybrid but it is see by OS (bios) like a standard HHD.

cheers

When you can purchase a 2TB SSHD for only US$5 more than a 2TB HDD, this is really a no-brainer.
