SK Hynix has announced the company completed recently the development of enterprise SATA SSDs built using its 72-layer 512Gb 3D NAND flash chips.
SK Hynix combined the 72-layer 512Gb 3D NAND flash with its in-house developed firmware and controller to provide the maximum density of 4TB, and makes 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, according to the vendor. The new eSSD supports sequential read and write speed of up to 560MB/s and 515MB/s, respectively, and can perform 98,000 random read IOPS (input/output operations per second) and 32,000 random write IOPS. SK Hynix also improved the esSSD read latency.
