The storage solution you're searching depends on the jobs you want to do and the uptime you/your job needs. If you need really high performance, IDE is IMHO not recommented. If you need 24x7-operations and near to 0 downtimes, it's recommented to have a look to http://www.icp-vortex.com/. They build RAID-controller which supports 2 external disk array where one of them is mirrored to the other one and supports a take over when one machine fails. If you need high extensibilty, an external solution (eg. Fibra Channel) may be right. If your disk space requirements didn't change or you need not really much, a simple vinum-controlled RAID-1 or RAID-10 may help. A simple Ultra-SCSI controller may fit you requirements, but the disks are more expensive. ATA-RAID controller may fit, too - but I read sometimes 'bout not supporting FreeBSD or data loss and no support, ... My expirience with ICP-Vortex is very well. They answer all my stupid questions and help me (eg. I had deleted my RAID array when I was adding a new hot swap disk). The support FreeBSD (ok, others do, too) and regular update their bios for increasing performance. They also provide unix tools to monitor the disk/volume states. Hope this helps.
