Yeah, an EA is going to be the only way to do that right now. I had looked to see if you could use something like HD size for this, since generally speaking, SSDs come in multiples of 64, such as 128 GB, 256 GB, 512 GB, etc. Most spinning platter disks come in more rounded number sizes, like 250, 500, etc. But since drives are often reported in the JSS in sizes like 256.08 GB and aren't consistent its not really feasible. The JSS only uses Less than, More than, etc modifiers for the HD size criteria, not "Like", so you can't use something along the lines of: HD Size | Like 256. Or HD Size | Like 512. etc.
