Nanoionic hard drives use nanoionic technology allowing for smaller devices while doing away with moving parts and the mechanical failures which are associated with previous HDD drives. Nanoionic hard drives are currently the most state of the art drives on the market and nanoionics was not utilized in hard drives until February 2014. Nanoionic devices were first proposed in 1992: "The results obtained show that it is possible to form arrays of electrochemical devices with single elements ~10 nm in size in the films".〔Despotuli A.L., Nikolaichik V.I. A step towards nanoionics // Solid State Ionics 1993 V.60. P. 275–278.〕 The basis of design of nanoionic devices is the creation of nanostructures with nanoionic parameter ''λ'' / ''L'' ~ 1, where ''L'' is the size of device structure, and ''λ'' is the characteristic size of specific region where the property of fast ionic transport is realized. “Possibilities to influence on these specific regions < λ > in a controllable manner may appear in short sized devices”. Ion - electronic hybrid devices should be considered as a step on a way to the future nanoelectronics-nanoionics (nanoelionics) that was first proposed in 1996.〔Despotuli A.L., Andreeva A.V. Nanoionics: New materials and supercapacitors // Nanotechnologies in Russia 2010, V. 5. # 7-8. P. 506-520.〕 == History of nanoionic devices == The First HDD Hard Drive was made in 1956 by IBM. It weighed nearly 2000 pounds and only could hold 5 MB. The first HDD Drive was 60”long,68”tall, and 29”wide. It was used in IBM’s RAMAC 305,the first computer to use HDD drives. Since 1956 the principle of storing information via magnetic domains has not changed much. As time progressed HDD drives were able to store more information than the original and the parts became much smaller, but the moving parts that are used in HDD drives were here to stay until nanoionic technologies began to be utilized in hard drives. In 1976 the first Solid State Device or SSD was made by Dataram and could store up to 2 MB. The SSD did not become popular until 2001 when SSD the SSD industry its revenues reached $25 million a year and was listed on INC 500 fastest growing private companies. The reason for this slow growth was that SSD were expensive. In 1978 1 GB would have cost $1 million dollars. Even in 2001, Adtron’s S35PC 3.5” SSD drive which had 14 GB storage cost $42,000. The idea to utilized this technology began at Arizona State University in 1992 and in 1996 the nanoionic supercapacitor was the first device to use nanoionics. The first drive to have this technology was invented by Dr. Michael Kozicki at Arizona State University 1996.This technology was then used in multiple universities around the globe, but did npt become available to the public until February 2014.〔(【引用サイトリンク】url=http://encyclopedia2.thefreedictionary.com/programmable+metallization+cell )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nanoionic device」の詳細全文を読む スポンサード リンク
