Old SCSI software RAID vs Newer SATA
Hey folks, I've been wondering about some hardware speed issues. For access and I/O time specifically. I have a pile of older 9gb SCSI Drives and a few 18gb, something like 10x 9gb and 3x 18gb.
If I was to make a software RAID 5 using an Adaptec 2940 PCI card and how would it perform versus a much newer SATA drive? Or better yet, is is possible with Ubuntu to do RAID 1+0?
