Samsung has unveiled new high-performance high-density solid state drive (SSD) models offering a terabyte (1TB) or more of storage capacity.
Announced at Samsung's SSD Global Summit in Seoul, South Korea, the new drives comprise the SSD 840 EVO line aimed at the consumer market while the SSD XS1715 line targets data centre storage applications for enterprises.
The SSD 840 EVO line (pictured) will be available from August in capacities of 120GB, 250GB, 500GB, 750GB and 1TB. It boasts significantly higher sequential write performance than the previous generation, according to Samsung, and is based on the firm's 10nm 128Gbit Nand flash chips.
Samsung claimed it has also narrowed the differences in performance across the different capacities, with the 250GB model delivering a sequential write speed of 520MBps, making it more than twice as fast as the last generation while the 120GB model achieves 410MBps, an increase of three times over the previous generation.
For the top 1TB capacity, sequential read and write performance has reached 540MBps and 520MBps, respectively. Meanwhile, Samsung claims that random read and write performance has achieved the highest level, at 98,000 input/output operations per second (IOPS) and 90,000 IOPS, respectively.
The SSD XS1715 line aimed at enterprise customers is claimed by Samsung as the first 2.5in SSD to meet the NVM Express (NVMe) host interface specifications for accessing SSDs on a PCI Express connection, and set to be available in the second half of this year.
It is set to ship in 400GB, 800GB and 1.6TB versions and is capable of sequential read speeds of 3,000MBps, making it 14 times faster than a high-end enterprise hard drive for server use, and six times faster than Samsung's older high-end enterprise SSD storage.
Samsung said that enterprise buyers will see dramatic performance improvements by upgrading storage systems in the data centre from hard drives or Sata SSDs to the NVMe SSD XS1715. The firm also said it plans to develop a variety of NVMe SSD products with increasingly high performance levels over the next few years.
