2TB of SSD for $150.000 sounds like the supplier is taking a very high premium. Looking at Intel's server-class X25 (the best choice in my book at the moment), the retail price for the drives is $30.000. As using the enterprise-class drives for the "Write once a day, read all the time"-workflow is overkill, one might even argue going for the mainstream drives, putting the price for 2TB at $7000.
I realise that the enterprise world does not normally permit sending a guy down to Newegg to fill a bag (a small and light bag in this case) with SSD's, but that is more or less the way we're going as we're ramping up for TB-scale indexing this fall.
