My friend is a camera operator and is looking to take two SSDs together for a portable raid. AFAIK modern raid like that is an old school approach. I recommended he set up a little server or the easy way out and just look for a JBOD enclosure. Am I wrong? Are there trustworthy enclosures that handle the raid without much set-up today?
You can get a hardware-mirrored external USB3.0 drive with 6TB usable (12TB raw) for under $175 from NewEgg/Western Digital
Just plug it in and it works
