Raid 0 and Trim

[doorules]

OK, someone tell me I am nuts here. In the help section of the new 11.5 rst drivers... Can be found in the Introduction, Getting started




That says trim in Raid 0, it does doesn't it????

[m.oreilly]

yes it does! these the ones up on that french site?

i tried hacking the rst app installer infs for the x79, but so far no go, as beer:30 intervenes (it's miller time, with a twist: while out of town, the wife picked me up some sam smiths oatmeal stout, and paulaner salvator!!!).

it appears to only work with win8 from what i am hearing, but have not confirmed myself (yet)

Nice find, and OMG, someone is reading the manual... which is what separates the men from the boys.

Checked the IRST 10.8 help, and the same section you posted does NOT say TRIM is supported in RAID 0 arrays. Just saying that the documentation has been changed for the 11.5 driver. If true, talk about a soft-launch. Or is it because it is only for certain drivers/chipsets?

I can't find any RST 11.5 driver on Intel's site, via the Download page. They don't list the "7-Series" chipsets in the Chipset download list, only X79.

Intel 7-Series Desktop boards have 11.1 IRST for their Z77 boards, which is listed as compatible with their P67 boards, I wonder if that will install on my ASUS P67 board... I may have missed this?

Oh yes, that French download site...

Edit...............

Never mind, found the other thread and link to 11.5. Windows 8 Beta driver from Lenovo? Whatevah...

if a trim command, it should be gold, unless 8 handles the port drivers different...

[doorules]

Ah, if only on W8 I guess I won't be having trim with my R0 array any time soon.

[m.oreilly]

lol...well, i'm tempted to play along and see...

some are saying you need the corresponding orom. i've also heard that the 3 series of drivers/orom for the x79 platform will contain whatever is necessary for trim in raid. the 11.5 is an 'e' series as it looks (two driver). looking at a german site, a fellow by the name of fernando posted up this, in response to someone asking about the 11.5 orom:

> Intel RAID ROM RST v11.5.0.1347 < (for DEV_2822, ie from ICH8R, Attention: This ROM module is actually in the RST "Enterprise" serie)

From my perspective...the company that Intel has not yet decided whether to the two-track driver development (from brush for X79 and RST for all other chipsets ICH7) Instead, change or retain any future AHCI and RAID drivers on the brush-concept with the two-driver strategy.
The main difference between the latest "RST" v11.5 series exclusively for the X79 chipset is provided brush-brush-RAID drivers and ROM modules of v3.0 and v3.1 series is that the Series v11.5 on all RAID systems from other Intel ICH8 be used.

not sure what he means by 'brush' (google translate), and i'm pretty sure he means 'pch' instead of 'ich'. so, what i gather is that the 11.5 series is the 3 (x79) series for p67/z68/z77. can't wait for clarification...

That 11.5 is for sure an e driver, even though they don't say it. The low writes give it away.

The 11.5 driver installed on my P67 board and basically runs fine, with a few quirks. Windows sees all single drives as SCSI, and provides the same extra Device options available for drives on a Marvell chipset/driver.

The OROM display changed a bit, although I swear it's the same version I previously had (10.5...), and the Windows GUI is a bit different.

I agree performance is reduced.

But with 11.5 we have TRIM in RAID 0...? I want to believe... (?) do you have faith in TRIM? Or is that Intel?
