When you need extreme data access speeds, especially in a compact package, at a very low price, the Sun Fire X4540 storage server is your first choice. Where else can you get eight cores of AMD Opteron processing and 48TB of storage in a 4RU server? And at $1.20/GB? This is the industry's top storage server. By comparison, it gives you twice the capacity in half the space at half the cost of the competition.
