SSD raid 0 setup use separate SSD for gaming?

post #1 of 14
Thread Starter 
Hello, I just picked up 2x 256Gb samsung 850 Pros and was planning on running 500Gb raid 0 with 128k striping.

Where I'm still learning and researching is a term called Over Provisioning, is that needed with the new Samsung SSD with V-NAND ?

Is TRIM available for Intel raid controller in raid 0 and should it be used if so ?

You guys recommend just putting OS on the raid and games on a separate SSD ?

I have a few 500Gb 840's I could use for gaming, but would that lose the performance of the raid 0 and defeat the purpose ?

What is the current suggested configuration for page files or virtual memory, or is it even relevant anymore with 16Gb+ of 2133 or higher ram ?

I'm a little dated here with my experience and I am leaning on some advice here to bring me up to speed.

Thanks

Well you may wanna check the thread alot of the 840s are having very slow read performance after awhile and there is no fix as of yet. Its over in the SSD section.

SSDs are so fast that I wouldn't worry to much about stripe size 128K should be fine.

Trim with Intel controller should be fine in Raid 0 with newest drivers.

To be honest SSDs are so fast I wouldn't fret putting OS and games on them in Raid. The days of the OS being on separate HDD for speed seem to be long over.

Thank you, I assume same would be true about page file on separate drive as well then.

I read about the performance boost of the 850 Pro's vs the older 840's which is why I went ahead and upgraded. I supposed I could use one of the 840's as an image drive for raid backup.

I have a 10Tb NAS and trying to talk myself out of putting any storage drives in this new build and keep it all SSD, then again I could just use my NAS for raid backups too.

What do do with all the 840's now, ahhhhhh !

I use two 840 Evos (250GB) in RAID 0. Performance is great. The only issue is that when updating the firmware you have to break RAID and run the tool from a bootable device. Make sure you check firmware version to make sure it has the one with the "performance fix". The nice thing though is between the intel Raid Controller on my ASUS Maximus Impact and Windows 8.1 I just have to re-enable RAID on the board and it fixes everything.
I get about 1050 Meg read and close to the same write speed.

To be honest I'm not real sure how hard it is going to be to install the raid. I was thinking about ghosting my single drive and just copying over but I think I want a fresh install on the raid 0.

Are you saying that the SSD has firmware ?

Yeah it was super simple on my Asus mobo. Firmware is a must with these. The nice thing is even though I couldn't do it from Windows they have the Dos tool. The only scary part was I had to "break" the RAID array by disabling it so that the tool would identify them. Then I ran it for each drive. Rebooted into the BIOS and re-enabled RAID. Then booted to Windows...it took a moment but it said it was configuring settings and such. Then BAM! I was in Windows with my "better" firmware.

Once set in RAID they only show up as an Intel Raid array. The Samsung tools for Windows and Dos only see it as a big Intel drive.

Did you have to load the firmware onto USB or CD media to install via bios ?
