You should read up on basics of hard disks on Wikipedia.The invention of the first hard disk drive in the 1950s represented a leap in technology that lead to a whole new world of possibility for computers. However it's less messy when done with data than clown limbs. This is why defragmentation utilities can increase disk performance.įrom the analogy above, defragmenting a disk is like reassembling the clowns you cut into pieces to stuff them into the car. This means to read an entire file you have to seek between disk locations, which is slower than sequential access. Hard disks have great sequential read speed, so splitting your file across multiple platters could reduce performance.įragmentation results in files being on multiple parts of a disk. How data is distributed on platters is up to the disk manufacturer and perhaps up to the operating system. Throughput could potentially increase with additional platters, if the read/write headers can move independently. That requires research and development and is relatively expensive. The only other way to increase capacity is to increase your data density. If you want to market a 4TB drive then you need four of those platters. Use a larger car (increase your platter size, which isn't practical for a hard disk).įor example, a platter in a modern disk drive might be able to hold 1TB of data.Put the extra clowns in a second car (add a platter).This might unfortunately require the disassembly of these clowns, which is akin to disk fragmentation. Learn to pack more clowns into the car (ie increase the platter density).Circus management wants you to fit two dozen clowns into the car, but there just isn't space. Here's an analogy for you: you're a circus clown, and as part of your performance you stuff a dozen clowns into your mini. Multiple platters increases capacity by increasing the space available to store data.
