Can I change a RAID controller and keep the data?
I have 2 Seagate Barracuda 7200.10 3Gbps/sec SATA drives.
Since I have to start loading data tomorrow, I think of buying whatever SATA RAID controller I can find, and possibly replacing it later with a better card. Is that going to work, or do you usually have to re-format the drives when installing a new RAID controller? Thanks, Drew |

Personal experience: Adaptex SATA RAID controllers are trash. Slow, unreliable and hard to manage. Arno |

To some extent the cards are seen as unreliable, or at least less reliable than ppl expect. The gui management software is, however, the same as the IBM ServeRAID management. It is fine. However the HostRAID line in particular cannot utilize the software's full feature set. Normal operations and management aren't necessarily difficult, the cards are simply neutered. That makes abnormal situations difficult. The Adaptec cards and ROMB I've seen lack helpful command-line utilities, and bootable Utility CD's, and there's practically nothing as far as onboard diagnostics and configuration. I agree. Crap and a waste of time. |

Thanks, Drew If you want to go from a cheap host-based software assisted pci raid to, say a decent midrange firmware card, it's generally a fair expectation to anticipate it not to migrate. Consider OS software RAID or no RAID until you finishing doing your homework. Frankly you may consider staying there. |

Of course I mean DAS in this sense: http://en.wikipedia.org/wiki/Direct_...orage#Features Not _every_ kind of storage directly attached to any kind of HBA.
