RAID Solution

[Franco1]

A discussion in another section has me thinking about my current setup. I currently have 3 1TB drives configured in RAID 5 using the ICH10R. I also have 3 X25's configured in RAID 0 (for windows/apps) using a Highpoint RocketRAID 3510 card. 64k stripe sizes for both.

Would I see a big performance drop switching the Intel drives to the ICH10R and letting the separate hardware raid card manage the more demanding RAID 5? Are 3 X25's really overkill when considering these drives are used for the "bulk" of my day-to-day computer use, such as, streaming, compressing, extracting, converting, etc.

Any thoughts?

Thank you.

If you do a lot of sequential writes, raid 5/6/10 spindle drives can be cheap and fast with a good hardware controller.

Since Raid 0 does not require parity calculations, the ICH10R should be OK with the X25's. One thing you want to check is whether your ICH10R has enough bandwidth back to the system as some people have found 250MB/s limits to transfer speeds on the ICH10R. With two drives the lower latency of the ICH10R would probably make it the best choice. With three drives you may be wasting a full X25's speed if you are on an ICH10R with the ~250MB/s cap.

For the 250MB/s cap, I don't see that with my older ICH8R and 4 Raptors in Raid 0. I easily break that and my 4-7200.11 drives are even faster for total MB/s and I tested them when I first got them and they were far above 350MB/s. The funny thing is that my 3ware Raid card was slightly slower for Raid 0 but I got it for Raid 5, which absolutely blows the ICH8R away.

As I know, Highpoint RocketRAID3510 is hardware raid card(with Intel IOP341 processor),
you can use it in more complex RAID 5 to handle .
