SK Hynix starts sampling PCI-e 4.0 enterprise SSDs with 96-layer NAND

SK Hynix has begun sampling its PE8000 series enterprise SSDs. These SSDs are designed for use in data centers and have a PCI-e 4.0 interface. The company will begin sampling a PE8111 enterprise SSD with 1Tb-4d nand later this year.

The South Korean manufacturer started handing out samples of the PE8010 and PE8030 SSDs earlier this week. These SSDs use 96-layer TLC NAND with a controller of their own design. The PE8000 SSDs will be available in a u.2 and u.3 form factor. The PE8010 is primarily intended for read-intensive workloads, while the PE8030 is optimized for mixed use. The SSDs both have a storage capacity of up to 8TB.

The SSDs both achieve sequential read speeds of up to 6500MB/s and sequential write speeds of up to 3700MB/s. The random read and write speeds are 1,100,000 and 320,000 iops, respectively, according to the company. The memory manufacturer reports a power consumption of 17W. The previous generation of PCI-e 3.0 SSDs from SK Hynix consumed 14W of power. Compared to the same SSDs, the PE8010 performs up to 103 percent better with sequential read and up to 357 percent better with sequential write, according to the manufacturer.

In the second half of 2020, SK Hynix will also start sampling an enterprise SSD using ‘128-layer 4d-nand’. This is a variant of the company’s 3D-nand flash modules, with a denser cell structure and higher I/O speeds per die, Anandtech writes. The PE8111 uses a PCI-e 3.0 interface. The SSD has an Esdff 1u form factor, also known as e1.l.

The PE8111 has a lower bandwidth than the PE8000 series SSDs by using a PCI-e 3.0 interface. The SSD achieves sequential read and write speeds of 3400MB/s and 3000MB/s respectively. The random rates are 700,000 and 100,000 iops, respectively. According to the memory manufacturer, the PE8111 is the world’s first SSD with 1Tb-nand, which makes higher storage capacities possible. SK Hynix will initially release the SSD with a storage capacity of 16TB, although the company is also working on a 32TB variant.
