It is because there's been a slight NAND oversupply in the direction of the market, even amidst some "incidents" which have impacted international NAND manufacturing by as much as 3.5% just last month. Nevertheless, funding in new NAND factories has been rampant, as corporations look to capitalize on ever-growing smartphone NAND demand and the general enhance in storage area and velocity for ushering companies and applied sciences (assume AI and processing workloads, for example). Now is likely one of the best instances ever to buy gargantuan quantities of quick SSD storage - although it's anticipated that pricing will preserve on declining at the very least till the start of 2H18, end-users will probably fail to see this mirrored in a significant approach. The state of affairs could change barely in 2H18, although, with corporations lowering output in order to match market absorption of new NAND - shifting from oversupply to tight provide.
