8 enterprise storage trends to watch | #itsecurity | #infosec

The data storage industry is experiencing a major transformation driven by multiple factors, including the need for security, speed, efficiency, and lower costs. IT research firm Gartner recently predicted 23-times growth in shipped petabytes through 2030, a trajectory that promises to radically reshape and redefine current data center and IT operations. To stay on top of the storage game, keep a close eye on these eight trends.

1. DNA storage

DNA, when used as a data storage medium, promises a far higher capacity and more resilient storage environment than traditional storage architecture. DNA storage allows molecular-level data storage, archiving information directly into DNA molecules.

“The advantages of DNA-based data storage are its density and stability,” says Nick Heudecker, a former Gartner analyst. “One gram of DNA can store approximately 215 petabytes of data with a minimum life span of 500 years.” Just don’t leave the media out in the sun, however, since UV breaks down DNA.

It’s important to note that this is a long-term trend, however. While DNA storage is rapidly advancing, DNA media isn’t likely to become mainstream for quite some time. There’s currently no firm timeline for DNA storage availability, although some optimists hope that it may become commercially available by the decade’s end.

“Current DNA sequencing and synthesis technologies are too expensive and slow to compete with traditional [storage] infrastructure,” Heudecker says. Access latency remains high, currently measured in minutes to hours with a maximum write throughput of kilobits per second. “A DNA drive competitive with tape archival must support a write throughput of gigabits per second,” he notes. Achieving such speed would require DNA synthesis, the writing process, to become six orders of magnitude faster. DNA sequencing, the reading process, must become two to three times faster.

Even if access latency and throughput challenges can be successfully resolved, there’s still a steep cost obstacle to overcome. “Tape storage media costs roughly between $16 and $20 per terabyte,” Heudecker says. DNA synthesis and sequencing costs hover in the area of $800 million per terabyte.
