Dell Latitude E6440 RAID 0 with two SSDs speed test
Вставка
- Опубліковано 21 кві 2016
- I am using two 240GB PNY CS1311 solid state drives. One is installed in the regular hard drive bay, the other is installed in place of the optical drive. I removed the optical drive and bought a second hard drive caddy on ebay.
By default, RAID 0 is turned off in the BIOS settings. Only RAID 1 is available to choose. You have to modify a BIOS setting to be able to use RAID 0.
Link to the directions to change the settings www.win-raid.com/t438f16-Dell-...
Post # 22 has the best and simplest directions. It worked right away for me.
Let me know if you have any questions. - Наука та технологія

This was very help full for my dell e6540
I did just like this (mini modded):
1) removed
2) format the usb stick as FAT32
3) copy the bootx64.efi file into the flash drive under EFI\Boot\ -(--brains.by/posts/bootx64.7z)-
4) UEFI boot off the drive (F12)
5) type in "setup_var 0x19D" (should return 0x0)
Hi, hope your doing great. Great video by the way. Now... do you still have the bootx64.efi file?
Respectfully,
Mr. Carrasq
Sorry, no I don't. It's been a long time since a made the video and no longer own the laptop.
still avaiable at brains.by/posts/bootx64.7z
Hello sir, i follow exactly the directions to change the settings, but i can't enter the intel rapid storage technology Option Rom by pressing Ctrl + I while booting (with only one HDD inserted to mainboard).So would it be able to boot to IRST option rom when i insert 2 HDDs ?
Thank you !
My guess would be yes.
Bình Trần any update on this?
what bios did you use? or is this fake? cause e6440 doesn't support raid 0, it only supports raid 1
It definitely supports raid 0 otherwise I wouldn't have been able to get those speeds. By default Dell has raid 0 disabled but there is a way to enable it but it's been a long time since i did it. I don't remember it now.
Found it. Stupidly auto upgraded BIOS (which still worked), then some time later swapped BIOS battery and then it didn't work and would not restore from Acronis. I also had to use Linux to put the format of the two SSDs back to NTFS so Acronis wouldn't complain about non-compatible discs after I made it a recovery RAID.... Anyhow, just CTRL-I and change the VAR. The VAR change was re-done on the BIOS I have now and that works too :-) See my public comment above.

Found it.
Hello sir, what about the big brother 15.6" Dell Latitude E6540? Is the some directions like this laptop?
I never had a 6540 but they should be the same because they are from the same year.
@@loukola5353 Thanks for the info.Are these GPU ATI Radeon HD 8790(6540), and 8690 in 6440 is still OK for 3D work with Adobe product like Photoshop, Ilustrator?
@@loukola5353 How to enable RAID0 in my laptop Dell Latitude E6540? There is RAID options in BIOS, I have last bios A26, but I think, if you enable RAID in BIOS -this is RAID1 -for backup, not RAID0 -for speed -like your laptop.
