All of the steps listed above are ONLY for verification purposes. They are used to determine if the RAID0 value is actually named and located in the correct spot, I think.
The value name being (0x19D).
I had issues getting the "verification" process to complete so in the end I just skipped it all together.

I followed the above instructions and changed my 0x19D value from what it showed me 0x00 to 0x1.
I know above it shows the 0x19D value as 0x0 but for my e7440 it returned a value of 0x00, not sure if its a typo if just a difference between e6440 and e7440. Regardless changing the value to 0x1 enabled RAID0 when hitting CTRL-I. I removed the flash drive and set my RAID to RAID0. BOOM.

TRIM does work - verified with this.

As for benchmarks here is a quick AS SSD screen grab.

That is with two Samsung EVO 840 mSATA RAID0 64K had the option to go 128k but decided to stick with 64k for now.

This is great news to hear you guys got this working - much thanks k3nny, Oflo23 and Fernando! I was about to try this on mine, however the link to the tool hosted on sendspace appears to be dead. Does anyone have a copy of this they could upload somewhere or PM me it and I can host? I would greatly, greatly appreciate it! I am super psyched to get my two 500GB EVO's in a RAID0. Its just sad Dell makes us jump through all of these hoops to be able to do something that really should be available to anyone that buys their computers. Generally people that know what RAID0 is, and how to configure it, are well aware of the risks. The other 98% of people could care less and would never touch it. At least that's my opinion on it, which of course means nothing at the end of the day. Oh well...at least there is light at the end of the tunnel now!

Thank you thank you!! I will post my results once I get it up and running!

Thank you all for your replies, i signed up just to thank you.




My steps were much simpler after reading all the replies and the posts on other forums

1) Partition USB stick to 1GB (just so there are no issues if you use a large drive)
2) format partition as FAT32
3) copy the bootx64.efi file onto the flash drive under EFI\Boot\
4) UEFI boot off the drive
5) type in "setup_var 0x19D" (should return 0x0) << this is to check
6) type in "setup_var 0x19D 0x1"
7) type in "setup_var 0x19D" (should return 0x1) << this is to check
8) reboot and set your bios (if not set already) to RAID, then use CTRL + I to get into the Intel Raid setup, create your array, and off you go.

im using 2x of the stock Samsung PM851 SSDs that theoretically can read 540MB/s each ill run it through atto bench once win 8.1 gets laid down.

the stock SSDs are not nearly as fast as the Evo's the other guy had, but a significant increase in speed all around.

(i know the WEI scores dont mean anything in real life but i ran it anyways)

Hi Everyone,

Great article thanks for the help. I have also made this change and I am able to create a raid0 setup on my Lattitude E6540.

I'm running into an odd error whereby once I have installed windows to the raid array, it fails to boot, giving the error no boot device found. Windows seems to install ok but fails to boot from the harddrive. I have tried lots of different settings in the bios with no luck, I have also tried installing Intel RST pre windows, with no luck. Can anyone offer any advice?

Hi Dieter thanks for a quick reply.

1) Chipset: Intel ID0C04
Soutbridge: Intel ID8C4F
2) I'm not sure how to check bios driver version?? Please help!
3) Windows 10 Enterprise
4) 1 connected storage drive (Windows boot drive) Kingston Data traveller 3.0
5) Crucial_CT240M500SSD1
Crucial_CT256MX100SSD1

Thank you for your help!

Hey, thanks for the help.

Those chipset names were given from CPUZ.

The intel raid utility is the following version: Intel(R) Rapid Store Technology - Option ROM - 12.6.0.1867

Sorry to be more clear that is my windows installer drive that has my Windows 10 install. It is unplugged once windows has been installed, I just thought I should mention it. Windows itself was installed to the array.

Both drives were connected during installation. I have not tried booting to windows with the drives unplugged if that's what you mean? But these are the only drives in the system, if I disconnected them I'm sure it wouldn't work!

SATA operation is set to Raid On.

Thank you for your investigation!
