You wouldn't want one drive to have duplicated data as well as regular storage, and with 4 drives RAID10 would make the most sense to me with RAID5 a close second if you are using RAID edition or enterprise class drives.

For home storage, get an SSD for the OS and forget about RAID altogether IMO.

The reason why i'm looking to do a raid 1 with multiple discs is i'm going to be running it on a pfSense box with ideally 4 drives. I'm not looking for much but i want the fast read speeds you gain from raid 1 as well as the redundancy with out parity. i don't need striping as the data that is going to be written will be coming over my internet and the standard write speeds exceeded my internet connection so i'm only looking for the fast read speeds as i pull windows updates and such from cache.

then you should use RAID10 - fast read and redundancy (faster and safer than RAID5) - good solution for 4 drives and probably faster than mirroring 1 drive 4 times

You don't get increased read speed from RAID 1. It is only mirroring, no read speed increase whatsoever. Your posts show you don't really understand RAID and need to research more. RAID 10 is your best choice for redundancy without parity calculations if you have 4 drives.

So I was thinking about picking up a perc 5i for RAID 1+0, any issues with a z68 chipset?

I also have a few spare fans kicking round, but my HAF X has decent airflow, anyone think I will have issues with thermal limits?

Yes. You will need a 40mm fan on the stock heatsink on the PERC 5/i, even with a chassis with good airflow. I have a small one on both of my computers (both with PERC 5/i) and the card's chips still get warmish to the touch after running for hours if I touch the back of it after shutting the system off, even with the small fans on them. It's not "too hot" enough to damage it though, so a small fan is just enough to work.

If you can, I would suggest positioning the PERC 5 in the middle pci-express slots so it's hit directly with a side panel case fan to help. Just a suggestion, though. It's what I do with both of my computers here, even with the 40mm fans on em. One of my machines is an Antec 1200 chassis with excellent airflow, and the other is a Antec 300 (but the 300 is rather stuffed full of wires) but I still do what I can to keep the PERC 5's coolish since these aren't server chassis's. Plus a side benefit if you use a 40mm fan on the PERC with 3 leads, you can connect it to a fan header and monitor it with software to tell you if/when it's obstructed / failed.

You don't get increased read speed from RAID 1. It is only mirroring, no read speed increase whatsoever. Your posts show you don't really understand RAID and need to research more. RAID 10 is your best choice for redundancy without parity calculations if you have 4 drives.

 

You don't get increased sequential speeds (with mechanical drives at least - with many controllers you will actually get RAID0-like speeds from a RAID1 array of SSDs), but you do get improved access times for reads, which can increase speeds especially for random data.  Write access times take a slight hit however, so whether RAID1 gives an overall speed boost depends on your usage.

 

It would appear you have done a lot of research into RAID and the theory behind different levels, but maybe don't always know what happens with real-world usage... :)

If you have enough space to mount a fan on the PERC heatsink, it might be better to mount a larger heatsink instead and do away with the fan (less fans = less noise & fewer things to fail).  I have old CPU heatsinks (showing my age though - they're old socket 7 sinks) on my PERC 6's and they stay cool to the touch even with very low airflow over the card surface.  Downside is they make the card take up 2 slots.  If you have a HAF with decent airflow you probably don't have a particularly quiet case though, so this might not matter to you.

I have 3 200mm fans, one 230mm fan and a 140mm fan, all running at 100% most of the time...

But I don't have any old heatsinks.

I've researched real world benchmarking and theory, and also know that many/most RAID controllers don't implement RAID in the most performance beneficial way. Where is your proof with benchmarks that it is in fact better?

While I have read the THEORY that access and read can be faster, I have not come across any real world performance benchmarks or statistics that actually show RAID 1 as faster. This is the exact same findings as with the PERC controllers and RAID 10, where in theory you should get 4x Read and 2x Write with 4 HDDs, you only get 2x and 2x because of how the controllers implement RAID. The same goes with RAID 1 and most controllers, they don't give you the benefit of better read and access times because of how they implement RAID.

Looks like your theory is better than real world usage
