Prospects for the use of hard drives in 2020.

This trend will not change. It’s easy to understand the reasons: more and more organizations are choosing cloud solutions instead of investing in the development of their own infrastructure. At the core are new innovative companies. All this requires the analysis and analysis of artificial intelligence (AI) algorithms in huge data sets.

According to IDC forecasts, from 2018 to 2025, the total capacity of storage systems delivered to the market exceeded 22 zettabytes. 26% of this volume will be provided by flash equipment. But the share of hard drives will be much higher – 59%. Given the growing popularity of applications supporting the new 5G standard, enterprises and data center operators should consider all possible storage options. This is the key to the right investment for several years to come.


For example, solid state drives (SSDs): compact, energy-efficient, feature low latency and high performance. However, all these advantages are not cheap – usually 8-10 times more expensive than a hard drive with similar users. Level 0 is justifiable when it comes to a boot server or level 0 applications. You need to understand that these can be solid state drives.

In the past few years, there has been a decrease in the cost of each terabyte. Nevertheless, a detailed comparison shows that cost reduction This suggests that in the future, solid-state hard drives, despite technological improvements, will not remain more attractive in terms of cost.

The fourth industrial revolution, the development of the “Internet of Things” and subsequent data processing. SSD performance is ideal for short-term storage of the Internet of things. If they talk about long-term storage, analytics and archives, then here too, hard drives and tape drives win – they alone can provide sufficient capacity.


In accordance with the results of research conducted by Toshiba, solutions with a large number of hard drives in a configuration of 64 Kbytes) and at the same time three times as much capacity is displayed. Thus, multi-disc solutions with the right configuration can be a good alternative to solid state drives. Data centers should think about storage strategies: which data should be stored, which – not, whether compression is required when receiving data, etc. It is also necessary to pay attention to the deletion strategy in order to understand when the stored data is no longer necessary.

Interestingly, in 2018, the total storage capacity was four times less.

Opening a new production unit specializing in flash technologies costs about $ 9 billion, and putting products on the market takes from 18 to 24 months. It is hard to imagine what the manufacturer may demand from us or demand that the costs be on the mark, which can at least somehow compare with hard drives.

Hard drives are time-tested technologies, and all of them can be completely natural. One significant improvement is the capacity of hard drives. Hard drives are expected to increase by another 2 years. Toshiba has a similar experience: in 2017, the capacity of helium hard drives of the Nearline class was 14 TB, in 2019 – 16 TB. The use of helium in production allows you to make the hard drive plate thinner. Further developments in this area can be placed on disks up to 10
