I bought used enterprise grade SSDs for dirt cheap a few months back. Total bought 4TB x 4 pieces and hooked up as RAID 0 for mobile storage.

Nah. The data will sync back to my NAS when on home network.

I basically needed something with large capacity and can withdraw bumps and impacts on the move. SSDs are the only way.

Of course, I ain't gonna pay full retail price for those. Used ones just nice as long the MTBF and TBW are low enough.
