What stripe size do you recommend for my RAID0 (2 SSDs)

I am getting my second Samsung 830 256GB that I plan on putting into a RAID0. This computer will be my gaming computer and I also do photo and video editing. What stripe size do you recommend?
 
my instinct is to say 128K but I haven't seen anyone test different sizes of stripes for a while. are you running an intel 7-series chipset board? if not then you'll lose trim support.
 
I'm skeptical but that sounds promising. When you get it set up run
Code: 
fsutil behavior query DisableDeleteNotify
from an elevated command shell, if it reports DisableDeleteNotify=0 then you've got TRIM enabled in the driver.
 
Just to add I just noticed that ASUS just released a new BIOS with instructions on how to update the BIOS and install the correct RST drivers. I am assuming this will give me TRIM support.

Maximus IV GENE-Z BIOS 3603(for Win7 & Win8)
For proper operation, please ensure to update Intel Rapid Storage Technology driver to version 11.5.0.1207 and BIOS to version 3603 before enabling Intel Smart Response Technology.

Update procedure for users needing Intel Smart Response Technology:
(1) Enter OS, and ensure Intel Smart Response Technology has been turned off under Intel Rapid Storage Technology interface.
(2) Install version Intel Rapid Storage Technology driver to version 11.5.0.1207
(3) Reboot the system, and update BIOS to version 3603, then reboot.
(4) Enter the BIOS setup screen, press F5 to load BIOS default, then change the Intel SATA Port to RAID mode.
(5) Boot into OS, and re-enable Intel Smart Response Technology under Intel Rapid Storage Technology.

It would seem like it, although latest RST is 11.6. After you do all that you might try updating if you're not happy/TRIM isn't working.
 
Intel stats that Raid would only be supported under the x7x chipset, I know they just released a bios for x79 chipset to support it, Z77 already supported it. I know that with the 67/68 it is still not functioning even with the latest bios 3603 on my system.
 
I think the implication is that some BIOS have the update OROM in them already, just check by setting RAID mode and hitting Ctrl+I at boot during the Intel RAID BIOS initialization to see what version it is.

Yeah my Maximus IV and my buddies IV-Z don't have the supported OROM with the latest bios.... Honestly it's pretty stupid as the SATA chipset on the 67/68/77 is identical there should be no reason why a new OROM and support for it do not exist. The only reason that I can see of course is to force us to purchase a new motherboard.

Using a modded bios is something I won't do, but if something were to go wrong it's an excuse to upgrade right? LOL.

Well got home from work, downloaded the 3603 again from Asus and reflashed, nope no new OROM stil the old 10.x.x, so got a little crazy, researched the procedure for updating the OROM, thought to myself meh, if I kill my board I'll just by an 3930K and Rampage IV Extreme and kick some ass. So I modded the bios like I said I wouldn't do, flashed it and bang, 11.6.x OROM working, using Intel RST 12.x.x Beta and TRIM is functioning just fine, tool me all of 2 minutes.

Now the decision, should I secure erase my system and start over knowing that TRIM is 100% or should I purchase two OCZ Vector 256GB for RAID 0 or two Samsung 840 Pro 256GB and reload when they get here. Decisions decisions?
 
I used garikfox's modded 3603 BIOS with the updated OROM for my maximus IV gene-z gen2 board with no problems. I then installed the proper RST drivers. I'm all ready for when my 2nd SSD arrives. I double checked and enabled RAID in the BIOS and then did a ctrl+i to version the RAID ROM updated properly and my RST drivers are uptodate.

RAID OROM 11.6.0.1702

Here is the link to the forum thread where garikfox posts link to his modded BIOSes. If your BIOS isn't there he'll mod one for you.

Beta Drivers can be found http://www.station-drivers.com/ here.

:o

The beta drivers are timestamped older than the 11.6's

check the link above they modded the 3603 BIOSes for your board too.

The timestamp on Intel site is because of the release of windows 8, the 11.6.2 on station is newer.

I modded my own bios using the latest bios off of Asus.

Please post your benchmark results if you can. :)
 
Well I got my 2 Samsung 830 256GB SSDs setup in a RAID 0 configuration and tested the TRIM using a the HEX editor method here. The funny thing is the TRIM only seems to be done after a reboot but as per the webpage it could be normal.

My question is how do I know that its not the Garbage Cleaner of the SSD that cleared the file space rather than the TRIM command?

Also the "fsutil behavior query DisableDeleteNotify" returned a 0 but from what I've read that doesn't mean TRIM is necessarily working only that the OS is able to use the command.
