The drive has a standard 2.5-inch enclosure but is twice as thick as the 2.5-inch drives commonly used in consumer products such as laptops. Samsung has employed 480 of its recently unveiled 256Gb third-generation V-NAND flash chips, each of which has 48 layers of NAND cells, to achieve this data capacity.
The announcement was made at the annual Flash Memory Summit in Santa Clara, California. No price or availability was announced, though Ars Technica estimates that it will not cost less than GBP 5,000 (approximately Rs. 5,08,346).
Samsung claims to be the leader in terms of storage density and the number of layers possible on a V-NAND chip. Its third-generation chips are stated to be up to 2.2x faster and up to 63 percent more power efficient than their second-generation predecessors.
Up to 48 such 2.5-inch drives can fit into a standard 2U server chassis, for up to 768TB of storage. Enterprise-grade magnetic hard drives, by comparison, have reached capacities of up to 10TB but still have an advantage in terms of cost per unit of storage.
Samsung’s highest-capacity consumer-grade SSD are the recently launched 2TB 850 Pro and 850 Evo models.
