SK Hynix has announced SSDs based on 72 layer 3D NAND memory chips. The solid state drives using these chips are targeted at data center and enterprise usage, and will come in capacities of up to 4TB.

The SSDs with 512Gb dies will be available in both a SATA and PCIe interface. SK Hynix specifies sequential reads and writes of the SATA drive of 560MB/s and 515MB/s respectively. Random reads and writes are specified at 98,000 and 23,000 IOPS respectively. According to the company, it also improved read latency but doesn’t provide any numbers.

The PCIe drives will only become available in capacities of 1TB or more. SK Hynix specifies sequential read and writes at 2,700MB/s and 1,100MB/s respectively. Random reads are specified at a maximum of 230,000 IOPs and random writes are specified at a maximum of 35,000 IOPS.

Samples of SK Hynix’ new SSDs are currently tested by  server and data center companies in the United States.

The website of SATA-IO indicates the new SSDs will go by the name SE4011 Series and the SATA drives will be available in capacities of 480GB, 960GB, 1TB and 3TB.
