2 x Intel x25-m g2 RAID0 + TRIM?

hi,
as i know, usually raid0 won't support TRIM but i was wondering if anyone knows something about an upcoming firmware upgrade or so to fix this issue?

thanks in advance!

 

its not raid controller firmware, its the raid driver. intel matrix driver now passes trim or raid.

 

An Intel Matrix driver now passes TRIM to RAIDed SSD's?

Maybe you mean the newer Intel Rapid Storage Technology drivers?

 

I don't think Intel has gotten it to work with RAID. If they did, AnandTech and other review sites would probably be all over it.

 

I thought so!

 

Could you pass us where you got this info from ? thanks!

 

I'd like to know as well...

 

.. anyone?

 

The ATA Trim command cannot be passed through a RAID array, there are currently no drivers that support this feature, however in the mean time you can use the Intel SSD Optimizer to maintain like new out of the box performance on your Intel SSD drives. At this time, the ATA Trim command can only be passed to single drive configurations within Windows 7 utilizing the MS AHCI driver.

You can manually Trim your Intel SSD's with the Intel SSD toolbox.

 

So does that mean I can manually Trim Intel SSD's in a raid configuration or only single drives?

 

I am assuming both drives will show up in the SSD toolbox application but you will have to try it and let us know. The info was from this PDF... http://download.intel.com/support/ssdc/hpssd/sb/intel_ssd_optimizer_white_paper_rev_2.pdf

 

That is definitely the million dollar question .

 

I guess that pretty much answers it.. otherwise they would've stated an alternative, such as running the toolbox twice for each drive..

 

I guess you could image your array on a backup drive> format your SSD's>run the optimizer on the SSD's one at a time from a spare drive with a Windows installation + Intel SSD toolbox>reimage the array.

 

Ok but why would you run the optimizer tool on the SSD as it should have "out of box" performance already once formated?

 

With RAID drivers installed it won't have 'out of box performance', thats why.

 

I don't get that, if you format both SSD's it's the same as if you would get 2 new drives.

As all the optimizer does, is increase performance once you deleted files, if you format the ssd's and install an OS there won't be any deleted files or am I not getting something here?

 

No, data will still be on the drives and I have tested this by running HDTune graph on Intel X-25V after a format. After formatting the X-25V and running HDTune graph on the SSD as a secondary data drive the graph was the same as it was when the OS was on it. After running the SSD toolbox on the drive the graph was flat at it's highest level all the way accross just as if the graph was run when the drive was new.

 

ok, thanks!

 

The problem is that a regular format is just the same as deleting files; the SSD still holds on to the data unless you use a special formatting tool like AS-Cleaner that actually writes out (deletes) the data. This is why TRIM is so important, it lets the SSD controller know which blocks can be deleted so it will handle it automatically, instead of you manually overwriting with a separate program like AS-Cleaner or the SSD Optimizer.
