He has done an outstanding job and spent countless hours working on my Synology set-up and being sure everything is easily and quickly accessible and protected. My dead Drobos were a daily annoyance and potential nightmare. The only things I've had to purchase were the Synology box with 8 bays, the 16TB refurbished hard drives to fill it, and Bitdefender to protect everything. I'll put the leftover 10TB hard drives into my available ProBoxes and have a backup for everything. Frank has done all of this remotely from Hawaii!! I still don't understand how that works but am eternally grateful that Frank knows what he is doing!!
