I have an older Intel Core i7-920 cpu and motherboard that I'm looking at making into a file/Plex server. What would be a good, modestly priced drive? I was looking at a shucking couple WD - Easystore 10TB External USB 3.0 Hard Drives at BB for $179. I already have Seagate Backup Plus 5 TB external drive and WD MyBook 4 TB external drive I could use as well. Both of those are brand new units I picked up on clearance Also, would you recommend doing a raid for a personal server? I'm trying to decide if it is worth the cost.
