Write cache buffer flushing disabled dating

opinion

May be someone can help me. The board is running fine and power consumption is nearly as expected, but Write cache buffer flushing disabled dating problem is that the RAID5 mode seems to be useless because it is extremely slow. But none of these tips fixed my problem. I had ordered 6 but 2 of them did not pass my tests with the smartctl utility.

Installed is the latest driver version from the Intel Download side This should make sure that the RAID system is in power safe mode, most of the idle time. So hardware and cabling must be fine.

Does not fix the problem.

Israel I got read speed...

I do not believe that this is normal? And do not believe that this will fix the problem.

Turn off Windows write-cache buffer...

Your Initializing is not done yet and yes its normal for a big array to take hours if not days Once done enable Write-back cache in rapid storage-technology RST and see how it performs then. The result is better now but still not as expected. This does not happen, when I used the single discs without array configuration. So I still believe that something is wrong with the RST driver.

I have a p67 asus board with 16GB of memory and a i7 K. Installation was a breeze compared to some other implementations and the RST interface works really great however the performance was a disappointment. The write cache is enabled in RST for my volume. Is Intel throttling this software solution? Why is it this slow? I have previously had hardware XOR-accelerated raidcards and they were a lot faster.

Maybe someone at Intel could give some Write cache buffer flushing disabled dating and pointers to improve performance? Maybe a setting to increase the write cache? I want to chime in too. In IOmeter I am seeing horrible results for sequential K writes. I am seeing 7. Something is definately not correct with the write speeds.

My array is a bulk media store and boy does it take forever to move files to it! I am using GB of 3. I do want to say that the Crucial C is cooking though! Is this in any way related to the recalled chipsets? Are the drivers really concervative now?

I have yet to see any official response to anything on these forums especially regarding Rapid storage technology.

A lot of the documentation on the rapid storage technology Write cache buffer flushing disabled dating is outdated and ambigous. However you cannot specify the amount of write cache and the policy you want for it just turn it on or off. The more proffesional systems have a lot more settings for optimizing the performance but I am fine with Intel making it a bit more simple.

I know it does not state that on their website but that information is generally pretty outdated. I am aware of the problem with alignment issues affecting performance and hence use k sector drives 2TB Hitachi 7k Write cache is enabled etc. This is about a third of the write speed of a single harddrive?! This is totally subpar and not at all acceptable, how can Intel boasts about all the advantages of Rapid Storage Technology with this beeing the reality of RAID5 performance?!

Nowhere on the site are there any performance figures quoted, the reason for this is quite obvious. Also apparently the RAID10 implementation is inferior too due to them not optimizing how they write and read from the striped drives within each set. Most people respond to these posts that you should get a hardware raidcard. I have however done that several times before but was curious after reading all the marketing stuff on the website here. If Intel can not deliver acceptable RAID5 write performance it should state that on the website so people do not have to waste time installing this crap and beeing dissappointed.
