What are people using for external raid arrays? What is the current trend? Are people still using SCSI? My manager and I are doing research. When we tried to do Dell's selection criteria to pick the proper external raid array it said that we should use a SAN which cost about $15,000+. My manager was thinking that the company would only spend about $8,000. We also don't need SAN. I know I probably have not provided enough information but I am not sure what is needed. My manager did remark he wanted 15 drives.
