I'd like to get more stability and fast recovery for my server. So i decide to make RAID 1 (mirror) using 2 SATA hd, since using raid 1 i almost dont have to worry about hardisk failure. I want to use RAID 5 using 3 HD but this will cost me more. The server will running java using tomcat, and mysql db. But our vendor said that using RAID 1 is slower then using 1 HD. Is this true ? If i use as application server using database, would be enough ? Another thing, I use softraid from yast.
Software RAID level 1 is slower than 1 harddisk? Not true. Writing and Reading speed is good. But, it's the most expensive solution in terms of money per MB. Software RAID level 5 is slower than 1 harddisk? Partly true. Writing performance is a bit slower since it must calculate the parity. Reading speed is good. I use software RAID 1 on my mailserver with 2x150GB sata Seagate. So far it's satisfactory.
