Hard-disk drive maker Seagate Technology Plc is getting closer to reaching its goal of making 20TB hard drives by 2020.

During the company's earnings call related to its good overall second quarter results, Seagate said that it plans to start shipping 14TB and 16TB hard drives over the next 18 months.

Seagate CEO Stephen Luczo said that a 12TB drive based on helium technology is being tested, and the feedback is positive. Currently, Seagate's top HDD has a capacity fof 10TB. Prices are
starting at around US $400.

Hard drives have lost market share to faster solid-state drives, but they have a strong presence in PCs, servers, surveillance and network-attached systems.

Seagate also plans to release a 60TB SSD later this year.

Seagate posted higher-than-expected second quarter profit and revenue and forecast third quarter revenue of about $2.7 billion.

Seagate also said it expects to achieve revenue growth this year with a profit of at least $4.50 per share.

The company's net income rose to $297 million, or $1 per share, in the second quarter ended Dec. 30, from $165 million, or 55 cents per share.
