Why is it so expensive still to purchase large quantities of memory per month. Right now our largest server is using just over 100GB of its 128GB memory. We would like to move to a new server now (we have had this one about 2 years) and upgrade to 256GB but the prices are ridiculous per month for memory. We have looked at ReliableSite and OVH so far. What else is out there that has a good datacenter and good memory prices?
