This is an example of where technology is clearly changed/reduced only to save money for the mfg at the expense of the unknowing consumer. Removing DRAM only benefits the mfg, and it's bad for the consumer, especially when they don't know the technology limitations.
So that being the case, it should be priced WELL below the pricing of competing solutions with DRAM (like Adata's own SX8200, as mentioned.) Pricing it only $10-20 less is a joke & a rip-off of the consumer, because no one is saying "I'd like to waste more time every single time I use my computer just to save $10".
P.S. Calling this drive a "prosumer" model is also a joke.
