NT1110 08/02/12 Unit 6 Analysis: Memory Cost IBM produced the first commercially produced hard drive in 1956. It came with the shipment of an IBM 305 RAMAC system including IBM Model 350 disk storage. [4] US Patent 3,503,060 issued March 24, 1970, and arising from the IBM RAMAC program is generally considered to be the fundamental patent for disk drives and only stored 5000 characters. Looking at the timeline of commercially produced hard drives. The 100 TB hard drive will probably be available within ten years. At the rate at which technology is growing and more companies becoming involved in this race, the 100 TB hard drive is closer than we ever expected. Hitachi Global Storage Technologies produced the first 1 TB hard disk in 2007. This ground breaking release opened the eyes of many companies and let them know that hard disks were going to continue to grow and expand in the near future. Every year after its release other companies like Seagate and western digital began producing higher capacity drive increasing by 1 TB. Looking at this it might seem that that 100 TB drive is far away but with new nanotechnology, hard disk producers have more space to work with therefore more hard disk space. The HAMR drive by Seagate is making hard disk capacity jump astounding with 60 TB prototype. They say the 20 TB drive will be available the in next year or two. So I expect a 100 TB drive available within the next 10 years. According to Moore's law the computer technology has doubled every year 08/02/12 NT1110 from the invention of the integrated circuit in 1958 until 1965 and predicted that the trend would continue for at least ten years. Knowing now that this wasn't true all computer components must evolve every couple years. Applying this to RAM, memory costs should lower and the size should increase. So basically you'll get double the power every three years for the same price. So if you buy 4GB of RAM for 100$ today, 10 years from now you'd get 32GB of RAM for the same price. These results should evolve with time and continue to apply to Moore's law. Hard drive capacities are growing exponentially and the prices are going down. 50 years ago hard drives cost 5,000 dollars for megabytes and today you can purchase a 1 terabyte drive for around 100 dollars. With this information you can see that the size of hard drives are increasing and their prices are decreasing. With nanotechnology had drive producers can do more with what they have. I you can purchase a 1 terabyte for around 100$, then in 10 years you should be able to get a 20 to 3o terabyte drive for the same price. With technology increasing every couple years this should stand true in the future. ... View Full Document
