It just ain't worth it. Depends a lot on how fast the disks and the bus the data has to get through are. If the bus is not wide enough (or the readahead is not big enough) for you to keep all the disks streaming, performance will probably suck. Other than that, raid 0 can be a significant win for large file access. For a small file, it doesn't make much of a difference, since it's likely to be in a single disk. -- Alexandre Oliva http://www.ic.unicamp.br/~oliva/ Red Hat Compiler Engineer aoliva@{redhat.com, gcc.gnu.org} Free Software Evangelist oliva@{lsd.ic.unicamp.br, gnu.org}
