FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -It took 51 years before hard disk drives reached the size of 1TB (terabyte, i.e. 1, 000GB). This happened in 2007. In 2009, the first hard drive with 2 TB of storage arrived. So while it took 51 years to reach the first terabyte, it took just two years to reach the second.

Detailed explanation-2: -Most hard drives have a lifespan of three to five years.

Detailed explanation-3: -Then after three years, hard drives begin to wear out. The bottom line is that a hard drive’s components can only move so much before they begin to fail.

Detailed explanation-4: -Disk media diameter was initially 24 inches, but over time it has been reduced to today’s 3.5-inch and 2.5-inch standard sizes. Drives with the larger 24-inch-and 14-inch-diameter media were typically mounted in standalone boxes (resembling washing machines) or large equipment rack enclosures.

Detailed explanation-5: -Most hard disk drives (HDD) last three to five years before some component fails. That doesn’t always mean the drive is irrecoverably broken. But three to five years is still about how long they last, whether you’re talking about an internal drive for a server, desktop, or an external HDD.
