I currently have four 400GB IDE drives in a RAID-5 array, giving me 1.2TB of total storage space (one of the four disks is used for parity and recovery data). I'm looking to upgrade my array to achieve at least 6TB of usable storage space. That would mean I need seven or more 1TB drives and a card capable of handling all of the drives simultaneously. I can't find any RAID cards or other solutions available that will do this for me. Does anyone know of anything that will give me 6+ TB of storage space and allow me to utilize RAID-5 redundancy? Thanks in advance.
