I've got a PERC H710 that I would like to start using and need some advice for the best route. I have available 4 x 3TB WD Reds and 1 x 100GB S3700. My intentions are RAID10 with cachecade. Would another S3700 be needed to help with cachecade or can I just get by with just one S3700? This array will be strictly for only storage (Linux ISOs). Any advice would be greatly appreciated. Thanks!
