At Present, possible number of different storage devices introduced in internal, external and network are attached each with their own purpose and application. Internal storage is generally termed as a hard drive or Solid-State Drive (SSD), which will host your computer’s operating systems and programs. External storage arrivals, mostly in the form of external drives, which connects to a computer through a peripheral port, like USB or Thunderbolt. Finally, Network Attached Storage (NAS) solutions connects with a switch or a router giving storage room and services to the entire network. Just have a look on upcoming storage devices which will make your 2016 outstanding.
Compact and capacious portable drives
We always flatter for enormous capacity with fewer prices, where available portable drive capacity with laptop disks inside can extendable up to 2000GB (2TB). Most of the USB drive is automatically activated when the computer is turned on.
Today, smallest portable hard drives come in size of 500GB, which is sufficient for your personal data backup. An eminent application of a hard drive is maintained for personal data on your computer or laptop. Some portable drives have software abetmenting you to take your all backup automatically, holding your chosen directories sync in once you plug in the drive.
Day by day USB is updating its performance with its earlier version, e.g. USB 2.0 to USB 3.0, improved in standard for connection in less time. For an instance, transferring a file required 100MB/s which is now one third of the speed.
Is thriving design with handy feature hard drives really works for an internal data? Check for the shock-resistance ratings like the US military MIL-STD-810F 516.5, a transit drop test which means withstand being dropped 26 times onto a hard floor, once on to each face, edge and corner, from a distance of 1.22m.
Annealing the Security
A lot of quibbling arises if the drive is stolen or lost. How to get your data back or how can you identify that your data is not read by anyone. Yes, there is a way to ensure it either by hardware or software encryption of the device. Though it is a way for detecting keyloggers and other malwares, it is hard-coated into the drive may change or upgrade.
Increased number of people have inclined towards an external hard drive to enhance their laptop’s storage capacity. While Solid State Drives (SSDs) abide comparatively expensive for the amount of storage, where standard USB external hard drives are becoming affordable with increased capacities.
Shingled Magnetic Recording (SMR)
New hard drive recording technology SMR, with helium-filled drives, enables for intense capacity on hard drives than regular storage methods.
SMR achieves higher areal densities by grasping tracks closer together. Tracks overlap with each other, like shingles on a roof, allowing more chunk of data to be written to the same space. As new data is written, the drive tracks are trimmed. Because of the reader element on the drive head, which is relatively smaller than the writer, all data can still be read off the trimmed track without compromising with data integrity or reliability. In addition, traditional reader and writer elements can be used for SMR. This does not require significant new production capital to be used in a product, and will allow SMR-enabled HDDs to save expenditure.
In 2014, the first SMR hard drive, which improved hard drive density by 25%. At $260 for 8TB, is a cost-effective drive for backups and archiving though not necessarily in the performance, the drive still has a 5,900 rpm spindle speed.
Traditional hard drives are covering 10TB now, but that could appear like a small amount of space if DNA-based storage takes off. According to the recent research, based on the currently understood science, it could be possible to encrypt all human knowledge in about nine liters of solution.
Why use DNA?
The density of the data is the basic reason. DNA’s Storage capability and stability are better than magnetic tape backups and flash memory, which might perpetuate for several decades, the life of DNA storage is consistently uniformed in centuries.
DNA is a storage medium and building custom DNA strands that can be read reliably is the challenge. The expert teams that performed the new studies acknowledged that it is presently pretty expensive to do this, but the cost is expected to come down dramatically in the next few years.
The self-assembling nature of DNA could make it possible. A file can be encrypted across thousands of DNA strands, but the data can be retrieved by amplifying the DNA through a process of polymerase chain reaction (PCR), which also makes DNA fingerprinting possible.
Encryption and decryption is a complicated process, with improved technology, DNA storage might be not as speedy as accessing a hard drive. However, many long-term storage systems can take ages to access as archived tapes or drives are located and powered up. DNA storage with its vastly improved data density could be an impeccable choice for this application.
More Futuristic Storage Technologies
Experts and IT companies have been working on holographic data storage from last decade. In 2011, GE exhibited its holographic disc storage: DVD-sized disks that could store 500GB it could possible just because of fixing the data onto layers of tiny holograms rather than Blu-Ray discs, which store data only on the surface. These discs also had a normally long lifetime prediction of 30 or more years. Not much has been said about the Holographic Virtual Disc (HVD), one of the biggest developers of the holographic drives, InPhase Technologies, went belly up in 2010. Moreover, the technology won’t be a prominent storage technology in the future.
It maybe quantum storage. Scientists are down the line doing research on the ways to store data using quantum physics. For an instance, a bit of data attached to the spin of an electron. Right away this technology can only store wee amount of data for a very short time, but if it works and takes off, we could view instant data syncing between two points anywhere, possible just because of the quantum entanglement.
