For a long time I preferred the 3ware controllers over Mylex, Adaptec and LSI-based products even though they were dead slow in comparison. Mylex tended to destroy RAID sets if one made a mistake exchanging dead disks, LSI controllers often forgot their configuration and only repaired sets if the replacement was made by adding a new spare to the controller (having a different SCSI id than the disk that was broken) and activating it and Adaptec... don't make me cry. Most of our customers replaced all controllers by ICP GDT controllers; Adaptec having bought them and _of course_ replacing them by an inferior (yes, I tried the ARC series) product got me a bit afraid - I don't care for the price of the equipment but I need safe mechanisms.
