Intel Rapid Storage tech vs Samsung magician

I was doing a fresh install of my system this weekend with some new Samsung 840 evo pro drives I picked up.

It comes along with 'samsung magician' software to manage the ssd's. It looks fine, tells me when new firmware is out, can benchmark drives, 'optimize' them etc.
I hit a problem when I updated my Intel RAID drivers from a version 8 to version 11. Intel driver check told me to update it, when I did and I rebooted magician then tells me it cannot communicate with one of the ssd's. I look into it and it's created a duplicate ssd in the drop down. And it's now locked me out of all the options for optimizing, over provisioning, benchmarking etc. for all the drives.

I've done a little bit of research and came up with the info that samsung magician does not like RAID at all. I don't have the samsung 840s in raid but 3x 300gb velociraptors in RAID0 set in my bios.

So I've read that if I have my motherboard set to AHCI in the bios magician helps a lot. I kind of noticed this when magician tells me AHCI is disabled, even though my system is set to RAID which uses AHCI.
Anyway, question is seems I'm either stuck in this old version 8 of the Intel raid driver which works with the magician software or if I should just delete magician and update my Intel RAID drivers with the rapid storage technology driver.

What provides me most benefit? Magician with an old Intel raid driver? Or a new Intel raid driver with no magician?

Any advice is much appreciated.

I would use the new Intel drivers and not use Magician until the issue is fixed -- AHCI is a subset of RAID so your 840 EVO will work fine, just like if you were running AHCI SATA mode since the drive is not part of an array.

Its not going to be fixed, Magician is intentionally not supposed to see SSDs when in RAID mode. There are exceptions, like if you're using an AHCI driver and not a SCSI.

So, even though my SSDs are not in RAID, the fact I have my motherboard set to RAID (which by default uses AHCI) still causes a conflict with Magician?

I understand why having your ssds raided will cause an issue as the OS sees it as one drive but I'm amazed samsung didn't design magician in mind with people using their ssds in a non RAID state but having some different SSDs in RAID.

If you're not using RAID, then why not just turn it off in the BIOS and just leave AHCI enabled? Though if its similar from switching from IDE to AHCI, i could see why you wouldn't since you wouldn't want to go through reinstalling the OS.

Also, in Device Manager, under the Disk Drives drop down, does it list your Samsung SSD as a SCSI device?

He is using RAID, just not on the SSD.

Yeah, I have a couple of SSDs for my OS and programs, which are not RAID.

The reason I have my motherboard set to RAID is because I have 3x300gb raptors in RAID 0 for my Steam library and music etc.

With RAID enabled magician plays well with the drives, its when I updated the Intel RAID driver which subsequently installed IRST onto my PC. Upon next boot up Magician then advises me it cannot communicate with the SSDs.

Uninstall Magician and just know that your drive works fine and at full speed with motherboard SATA mode set to RAID and TRIM is fully functional. The problem is when you want to update your SSD firmware you will have to change the SATA mode and probably break your array.

Sorry about that, didn't see the part about the 3 raptors.

when you need to update the FW, just go to www.samsung.com/samsungssd , download the ISO for the FW update, use Windows Disc Image Burner to burn a bootable CD/DVD of the ISO, then restart the computer, go into your BIOS, shut off RAID, Boot to the ISO, do the FW update, then upon restarting your computer go into BIOS and just re-enable RAID

The problem is that changing the RAID bios setting, even temporarily, has a very high probability of breaking the array.

Thanks guys. So if I uninstall magician will it lose the 'rapid mode' settings? That setting doubled the speed of my OS drive.

This is pretty much the only benefit to using magician, if it's still enabled after uninstall if magician I would be happy and could probably update my firmware on a friend's pc to be safe.
