I just bought a new computer with a 2TO SATA disk with Windows 8 on it and a 32gb SSD drive. With the Intel utility that came installed, there is a possibily to use the SSD drive as cache to accelerate your main hard drive. However, when I go to the acceleration tab, it prompts me for which SSD I want to use (I only have one), ask me how much of it I want to use for caching (the whole thing), ask which physical disk I want to accelerate (C:), and asks which mode to enable (I've tried both).
Every time it pops up an error and says that an unexpected error has occured while tryign to enable acceleration and to restart my computer and try again. I've tried again and again, and get the same error every single time
I updated the firmware on the SSD, ensured that I had the latest iSRT installed, as well as checked my bios settings.
Please help, I have looked all over online and haven't found any clues.
I will be trying to set up such a system next week, so I have been doing some research. There are several requirements to use Smart Response. Have you complied with those, like have RAID set in the SATA controller?
Just a note, if you are not currently using RAID, I certainly would not advise changing it, you might loose your system.
The requirements seem to require a 77 chipset of certain types although a video seems to suggest a Z68 would work.
You say the IRST shows 2 SSDs. Was it partitioned previously, and the partition needs to be as large as your installed memory amount.
Next week I may have better guidance. Right now I am still trying to see if there is any difference between Smart Response and Rapid Start.
Edit: I do have a Bios option to enable Intel Rapid Start...
Yes, I am using RAID in my Bios.
I looked at the characteristics of my motherboard and Smart Response is compatible with it.
IRST shows 1 SSD, not 2.
I have 16GB of memory installed, the disk is 32GB. That's the way my computer came from factory.
From what I read, Rapid Start and Smart Response is 2 differents things. Rapid Start will accelerate your boot time, but thats it.
I agree about the Smart and Rapid differences.
The Rapid Storage utility has quite a bit of info in the help section, including a troubleshooting area.
Do the drives look normal in Disk Management? Do you have any reason to believe the SSD is defective?
If no one else responds, I will be back after I get my system set up...if I can get it set up..
I looked all over for this, even on Intel's help section.
I found one post on another forum with a guy who had the same problem earlier this year but I havent had a response from him.
Everything seems ok in disk management and I don't think the drive is defective.
I just got my SSD and set up the system. I will go through my process to see if you notice any differences.
SanDisk 32 GB "ReadyCache" SSD
Booted and open Disk Management. The drive was shown as RAW, so I initialized it to GPT (UEFI system).
Open the Rapid Storage utility, which took quite a while to come up. The Accelerate button was now visible and I selected "Enable Acceleration". Used, as you did, full capacity, Primary Hard Drive and Enhanced. There may be a difference here since I did not use just c: but the entire drive. I assume that is what is means by Physical Drive.
Hit OK and after some drive activity, the system showed "Enhanced Mode Enabled". The SSD disappeared from Disk Management and Diskpart. In the Rapid Storage utility it shows as Volume_0000, Type: RAID 0.
Since I have now gone through the process, I will be better equipped to answer questions.
Ok, two things.
- what do you mean by initializing the disk to GPT (UEFI system) ?
- you said you did not use just c: but the entire drive. Do you have a couple of partitions of the drive ?
The configuration of the drive does not seem to be important. The process will reconfigure it. So setting it to GPT for a UEFI install is not necessary.
I only have the option to select an entire hard drive to accelerate. Yes, there are 2 partitions on my primary (OS) drive, but I cannot select just C: . This is probably the same thing you are seeing. I don't suppose you are seeing an option to Disassociate the SSD in the Rapid Response window? If the SSD had be set up previously, it may still be configured for the other system, but this is just a remote possibllity.
The process seems fairly straight forward. Since it does not appear to be working that way for you, possibly a firmware update for the SSD may help. There are probably some SSD drives that might be incompatible for some reason.
Because the data transfer speeds were being reduced to such a great extent, I am no longer using the Smart Response Technology. My testing seems to indicate the transfer speeds for file transfers will drop about 90% in Windows 8 for large files (> 7 GB). Windows 7 seemed to be OK for me.
Edit: I have discovered the reason for the decrease in transfer speeds was the SSD I was using. Replacing it with a faster, but still SATA III, drive allowed the transfer speeds to function normally.
But I have now used 2 different SSDs for SRT and both could be set up and seemed to function correctly.
As you can see in the screenshot below, I have 5 partitions of my primary 2 Go disk. This is the way it came from the factory and I have not changed anything.
My first partition is a 600 Mo Backup Partition; then a 260 Mo EFI System partition. My C: 150 Go partition where my OS is installed and a D: Data 1600 Go partition. Finally there is a 15 Go Backup Partition.
I can not delete or modify or assign a letter to any of the backup partitions.
Do you think this is the cause of my problem ?
According to Sandisk, I have the latest driver for my SSD Drive.
I would try the following: Backup all your files of the Data (D:) partition to another disk or to C: and delete it or boot Linux to toggle the second NTFS partition to another non-NTFS partition type like 83 (Linux). Then reboot and try to accelerate the system partition - if you can accelerate it, it's nearly the same case as mine except that I don't use the GPT but the MBR partition scheme.
Lenovo U310 Touch, 500GB+24GB SSD ..Haven't seen an "Accelerate" option with my Intel Rapid Storage Technology so I went into BIOS, my SATA settings were set to AHCI, so I changed it to RAID, a few seconds later I scrolled down to your post that said "i would not advise to changing it".... luckily it didn't fry my system!! Any idea how I can get the Accelerate option? Thanks!!!
It is really not me that says that, but some OEMs. Probably it would always be better to install a system with the correct controller. But I have changed my systems on some occasions without problems.
Did you find a place to show you how to change them in Windows 7?
If the SSD was already in the system, was it being used for something else, like Rapid Start? Does it show up in the Intel Rapid Storage Technology as being available...? Some options may be in the Bios for such things.
After switching to RAID in the BIOS my system would not startup and I got some Windows 8 errors with a ":-(" sad face.. Luckily I was able to switch it back to AHCI and get my system started.
I have Intel Rapid Storage Technology Help opened and I'm reading through the requirements for Accelerating the system (found under "Cache Device Properties")... All I see is RAID-RAID-RAID, so I'm assuming RAID has to be enabled in order for me to see an Accelerate option_? I believe the SSD in my system is designed and has been implemented for caching (ExpressCache is installed) as well as Intel Rapid Start, although Lenovo themselves have informed me that Intel Rapid Start is yet to be compatible with Windows 8..
Not sure if I can successfully change my SATA controllers to RAID :-/ technically (if my machine is capable) or personally (I've never really been too familiar or comfortable with RAID drives)

In order to change it over, in Windows 7 you have to enable the Raid Controller in the Registry. There are several sites that show how to do this, but basically, you need to open regedit.exe and go to the following key.
On the right side, the "Start" entry has to be changed from 3 to 0 which you do by right clicking and modifying the value, then saving. It can be very dangerous to edit your registry, so take precautions.
When you reboot, in the bios change the SATA controllers to RAID. If you were to have the drives on a secondary controller, you would have to set it to RAID.
If you could find a site that takes you through the process, that would be good.
http://support.microsoft.com/kb/975453/en-us Error message when you start a Windows 7-based computer after you attach a RAID disk: "STOP 0x0000007B INACCESSABLE_BOOT_DEVICE"
I just wanted to pipe in that I was having difficulty with this issue on Windows 7 and the problem was having a partition on the SSD as ajb suggested. Afterward, the accelerate partition isn't visible in "Disk Management" so my guess is it's a Linux ext partition managed by the chipset.
The missing steps as I've seen them are:
1. Both disks need to be in RAID mode (although not configured) if your Windows is installed on a disk in AHCI or IDE mode you will need to follow the steps in this post to switch to RAID mode [http://www.overclock.net/t/1227636/how-to-change-sata-modes-after-windows-installation How to: Change SATA Modes After Windows Installation]
2. The SSD you intend to have as your cache needs to have unpartitioned space (up to 64GB)
3. Accelerate will use up to 64GB (on the H87) of space on the SSD and you can now go into "Disk Management" and partition the rest of the space for whatever you want.
