Storage is taking an increasing share of the IT infrastructure budget, and this trend will only continue as the Internet of Things, big data, and artificial intelligence grow. That's why we need new technologies to improve our storage infrastructure. 
Flash memory
Although flash memory is not new, the emergence of four-layer cells (QLC) - 4 bits per cell - and the widespread adoption of 3D flash memory are relatively new. Since QLC requires a larger unit size, the two are usually synchronized.
Both technologies take years to fully mature, but they show us the future of flash.
Storage level memory
SCM is a byte-addressable memory that holds data after the power is turned off, so it can be used for storage. At the end of 2017, Intel announced that it will introduce DIMMs based on 3DXPoint memory technology in 2018, but only a block-addressable memory, not a byte-oriented memory.
PCIE storage network
One company, Liqid, has created an installable PCIe switch using a commercial PCIe switch chip. Why is this so bright? In simple terms, it allows you to extend the server's PCIe bus out of the chassis, with all bandwidth and low latency.
Liqid is a software company whose main product allows you to create virtual servers from physical servers connected to PCIe. The idea is to build high-density computing, networking, and storage devices and use software to create virtual servers to meet the application's optimal performance needs.
Every server has PCIe, why not use it as an interconnect? By the way, this is the original concept of PCI many years ago.
High performance object storage
Amazon, Google, and Azure use object storage to store their massive amounts of data because it is much cheaper than Network Attached Storage (NAS), so these vendors only sell object storage when the customer insists. Once you reach the capacity threshold - about 250TB, depending on the vendor - it's even more cost-effective than renting, stored in the cloud.
However, the drawback of object storage has always been performance. But with the rapid growth of the concept of active archiving, people are beginning to realize that a well-designed object store can satisfy many applications quickly enough, especially considering cost. Large storage companies have not launched this business, so check out companies like Avere, DDN, HGST, Panzura, Quantum, and SpectraLogic to see if there is enough fast object storage.
Stored 2018
The original author of this article (RobinHarris) has been tracking data storage for nearly 40 years. He said that he has never seen a more creative time than now. In 2018, we will see that the pace of industry development will accelerate.
