SK Hynix: SATA/PCIe eSSD With 72-Layer 512Gb 3D NAND
Up 4TB, 560MB/s and 515MB/s sequential RW, 98,000 and 32,000 IO/s random RW, and 1TB PCIe SSD with 2,700MB/s and 1,100MB/s of sequential RW, and 230,000 and 35,000 IO/s random RW
This is a Press Release edited by StorageNewsletter.com on February 5, 2018 at 2:19 pmSK Hynix Inc. completed developing an enterprise SATA SSD (or ‘eSSD’).
With its 72-layer 512Gb 3D NAND flash chips, the company is paving the way for its full-fledged entrance to the high value-added eSSD market.
The firm combined the 72-layer 512Gb 3D NAND flash with its in-house firmware and controller to provide the maximum density of 4TB. The most of its 72-layer 512Gb 3D NAND chips to double the biggest density of the SSD of the same size with 256Gb NAND chips.
A single 4TB SSD could contain 200 UHD (Ultra-HD) movies, each of which is generally as large as approximately 20GB. This eSSD supports sequential read and write speed of up to 560MB/s and 515MB/s, respectively, and it can perform 98,000 random read and 32,000 random write IO/s.The company also improved the read latency, which is of the utmost importance in eSSD performance. The firm is sampling the product to server and data center clients in the United States.
The company also finished developing enterprise PCIe SSD and is shipping samples to server and data center clients. The PCIe SSD will also use the 72-layer 3D NAND and have a capacity of more than 1TB. The 1TB PCIe SSD operates at 2,700MB/s and 1,100MB/s of sequential read/write speed and runs random read/write performance of 230,000 and 35,000 IO/s.
“SK Hynix started mass-producing Client SSD with its 3D NAND chips and in-house firmware and controller last year. Now we have expanded our SSD business portfolio with the development of eSSD,” said Jin Kang, head, NAND planning and enabling. “The company plans to actively meet growing eSSD market demands to contribute to enhancing its profitability in NAND flash business” he added.
According to IHS Markit, the SSD market revenue is expected to total $25.1 billion in 2017 and post a continuous annual growth of 5.6% to total 31.2 billion in 2021. Especially, the revenue of the enterprise SSD will lead the market growth by rising from $13.4 billion to 17.6 billon at a CAGR of 7% during the same period.
