I have used software RAID in production on and off since 1998-ish using RAID 0/1/5/10. To date, I've never had one fail "ungracefully" and haven't had any performance issues to speak of. However, for the past 5 years or so, I've used mostly hardware RAID with an emphasis on 3Ware IDE cards. They just plain work and it is a lot easier if you don't have the time/energy to keep up with the latest comings and goings in the software RAID corner of the Linux world. They are also not THAT expensive. Lately, I've gotten to like the Highpoint RocketRAID 2224 and 2240 PCI-X cards since they have multi-lane connectors and support SATA II. The multilane connectors have made it easy for me to deploy external tanks of SATA II 500gig Seagate drives for video editing applications. The 2224 also has the benefit of being OSX friendly if you've got the need to support that in addition to Linux and Winders. If one of the lower end 3Ware cards is too expensive for your application, I wouldn't worry too much about deploying software RAID. It works and it's pretty painless to set up with the CentOS installer. Just make sure you budget a bit of your cpu power to deal with the overhead and that you test updates before you roll them out to a server that's doing real work (Tm). Cheers,
