^^^^Sure, and in the past there was the Apricorn Velocity DUO X2. I had one of those. But I'd rather not use a PCI slot. Currently I have six M.2 SSDs in my PCI slots. Two on a Syba I/O Crest and four on a Highpoint 7103. I also have 2½" SSDs that I pulled out of my 5,1 when I sold it. With the J2i I could use them. Do I need to - Heck No! But, since I have them I'd like to use 'em. The J2i could be a cheap solution.
