SK Hynix Inc. recently completed developing a 4TB enterprise SATA Solid State Drive ('eSSD'), featuring 72-Layer 512Gb (Gigabits) 3D NAND Flash chips.
The South Korean company combined the 72-Layer 512Gb 3D NAND Flash with its in-house firmware and controller to provide the maximum density of 4TB (Terabytes).
The new eSSD supports sequential read and write speed of up to 560MB/s (Megabytes per second) and 515MB/s, respectively, and it can perform 98,000 random read IOPS (Input/Output operations per second) and 32,000 random write IOPS. SK Hynix says it has also improved the read latency.
The company is sampling the product to server and data center clients in the United States.
SK Hynix also finished developing enterprise PCIe (PCI Express) 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 IOPS and 35,000 IOPS.
