My future setup is going to include 4 12" SSD's, but I can't afford them ATM, so I am trying to pick them up as cheaply as possible. I currently have a stock D1 SSD. Can I purchase two D1 SSD with the copper coils to use with my current sub? I am wondering because someone has two for sale for a much lower price then new. Or will I run into problems with cancellation and such? Thanks.
