I am preparing to build a new computer and wanted some advice about the best hard drive configuration for photo editing. My computer case has 6 drive bays and I intend on using a PCIe based SSD as the boot drive, a second PCIe SSD as a scratch and Lightroom Catalog drive and 6 SATA drives for image file storage. I want to configure the SATA drives in RAID in order to have redundancy and improved write speed. After researching the various RAID options, it appears that RAID 10 or RAID 5 would be most appropriate for this application but although I understand the concepts used in both of these designs, I don't have a firm understanding as to how they would compare and contrast in a real world sense with respect to write speed and data protection. I presume that RAID 10 would be best configured as a mirror of a three drive stripe.
