Hard disks eventually fail which stops the computer from working. Regular 'head' crashes can damage the surface of the disk, leading to loss of data in that sector. The disk is fixed inside the computer and cannot easily be transferred to another computer. The write head also can get damaged if the hard disks temperature to high.
Since HDD using spinning disk, storing and accessing data is slow and limited. Normally HDD spinning at 7,200 rounds per minute for HDD 3.5″ and 5,400 rounds per minute for HDD 2.5″. However, there is also a speed of HDD 10,000 rounds per minute and 15,000 rounds per minute on the market, but is not widely used because it is expensive.

Hard Drive is entering to the evolution stages which proven by SSD technology. SSD is stand for " Solid-State Drive ". It contains no actual "disk" of any kind, nor motors to "drive" the disks. Iis a data storage device using integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives, thus permitting simple replacement in common applications. Also, new I/O interfaces like SATA Express are created to keep up with speed advancements in SSD technology.
Unlike HDD, SSD writing/reading data much fastest than HDD because it used chip to store data. There's no spinning plate. There's many review that proven SSD is worth for gaming and graphic editing jobs. In additional, transferring a large file take a short time rather than HDD. SSDs use significantly less power at peak load than hard drives, less than 2W vs. 6W for an HDD. Their energy efficiency can deliver longer battery life in notebooks, less power strain on system, and a cooler computing environment. This can make your laptop battery last longer. As an energy-efficient storage upgrade for your desktop or laptop, SSDs require very little power to operate that translates into significantly less heat output by your system.

You'll notice, there's some noise on HDD while you're opening a large application like Photoshop, Sony Vegas. With no moving parts, SSDs run at near silent operation and never disturb your computing experience during gaming or movies, unlike loud, whirring hard disc drives.

Did you know why MacBook Pro was categorized as faster notebook now?
SSD is the secret, Apple had used SSD since 2008. As Apple had used SSD early, that's the reason why Macbook Pro categorized as faster notebook nowadays.
From price, SSD price more expensive with limited capacity. SSD with 120GB size can reached about RM450-RM700 but it worth it :)
