Hitachi Releases World's First 25nm Process Enterprise Grade Solid State Drive

In general, the semiconductor process is always the newer the better, but because of long-term reliability can not be adequate protection, 25nm NAND flash memory has been questioned by many users, many new technology SSD read and write times indicators even not as good Old 34nm product.

Today, Hitachi Global Storage released the first enterprise-class solid-state drive "Ultrastar SSD400S. B" with 25nm NAND flash memory, demonstrating that the new flash memory can still be used in places where reliability is very strict, and it can satisfy high-performance enterprise-class storage. need.

Ultrastar SSD400S. B uses a 2.5-inch specification, but it is "heavier," with dimensions of 100.6 x 70.1 x 15 mm, and a weight of about 222 grams. It uses a 25nm SLC single-layer flash memory chip, capacity 100GB, 200GB, 400GB, interface SAS 6Gbps, an unrecoverable error rate of 1/1016 in reliability, an average failure time of 2 million hours, 24x7 continuous work, maximum lifetime The three types of random write data are 9PB, 18PB, and 35PB, respectively.

Performance, 64K continuous read and write speeds up to 536MB / s, 502MB / s, 4K random read and write speed is the highest 57500 IOPS, 25500 IOPS.

In addition, the average power consumption is 1.7W in standby mode, 5.5W typical in read/write operation, and the power consumption ratio is 8360 IOPS/W.

Hitachi said that the SSD is suitable for a variety of enterprise-level applications, including enterprise servers, high-performance computing systems, space and/or power-constrained environments, online transaction processing, video editing, financial and e-commerce, and database analysis. Cloud computing and so on.

Hitachi Ultrastar SSD400S. B is accepting the evaluation of OEM customers. It will launch large-scale production in the first half of this year. It will provide five-year limited warranty or maximum data quality warranty, and optional encryption.
