I bought a 4TB SSD and installed it myself in my DX Gen2. The DX aLready had a 2TB SSD when I bought it (used).
I talked with Tony before I installed the new drive. The extra cables For a second drive were already installed and bundled up inside the unit. Tony told me when it was installed to call him and he would run a utility to span the drives, which would combine the storage into one virtual 6TB drive. Well a couple of weeks ago he remoted in and ran the utility and ten minutes later I have 6TB of SSD storage. Shows up as one drive. Better solution to me then an external USB drive.
SWEET!
