Hard disk is a vital component for a computer, but not everyone knows this device properly.
1. World in 988,000,000,000,000 Megabytes of data.
IDC market research organization in March 2007 stated that the amount of data stored in the world in 2006 reached 161 Exqabyte.Pada year 2010 is estimated to reach 988 exabytes, nearly equal to one Megabyte quadrilion.
2. Actual size.
Unit-inch hard drive in the world is not the physical state of the hard disk size is, but said the size factor.Sebuah form 3.5-inch hard drive actually has a width of 10 cm long, which means measuring 3.937 inches.
3. The world's first hard disk.
The world's first hard drive IBM pertamak operated 350 times with a giant IBM 305 computer-RA MAC.Dua separate heads to read and write data on magnetic disks 50 rotating at the speed of only 1200 rpm.Dengan capacity for 4.4 Megabyte.Space this Hardisk rent.
4. Miscalculation in the calculations.
In calculating the capacity, hard drive manufacturers use the power of 10 as basisnya.satu gigabyte equals the rank of 10 counting 9 byte.namun computers with gigabytes 2.satu base equal to 30 or 2 power with a capacity of 1,073,741,824 byte.Hardisk actually only 250 GB capacity approximately 232 gigabytes.
5. Moore law also applies in the hard drive.
The maximum capacity of hard drives every 12 months increased 2 times the current lipat.Hardisk reached 1 terrabyte.
6. The price has fallen dramatically.
price per 1 GB hard disk for about 10 cents dolar.dulu in 5.25-inch hard drive 1980, ST506, seagate, with a capacity of 5 MB, offered about U.S. $ 300 per MB
7. Density data.
Hard disk recording with perpendikular can achieve data densities up to 155 gigabits per cm kuadrat.jumlah is equal to 60 million times the density than the first hard drive data in about 50 years ago.
8. The smallest hard drive.
In January 2004, toshiba showing a 0.85-inch-sized hard drives in consumer electronics arena this mini show.HArdisk recorded in the Guinness Book of records and ready marketed.
9. Live longer at 40 degrees.
Based on data from google, hard drive will last longer bertaan at a temperature of 40 derajat.kondisi shorten disk age is above 45 degrees or below 30 degrees.
10. 5000 times thinner than hair.
Distance read / write head and magnetic disk surface is now only 10 nanometer.sebagai comparison, human hair has a thickness of 50,000 nanometers.
