Solid-State Drives (SSD) are starting to replace traditional PATA/IDE Hard Disks which have been around since the early days of Computing.
Now Flash based memory larger USB Memory sticks with larger capacities, can be used to read and write data instead of traditional drives where a magnetic head reads and writes across platters of spinning disks.
SSD Drives have been used in Military and Airline applications for years, now the price has dropped to allow them to be a viable option for home and business users.
They are more reliable, faster, and more durable than traditional magnetic hard drives. They consume less power which is a primary reason why they are widely used in Netbooks and Laptop/Notebooks.
With the larger sizes of SSD over memory sticks, and the ability to connect them using SATA, PCI Express you can easily have a drive inside your machine.
Or turned into a light, fast portable drive (with additional kit) which wont mind the odd knock unlike 2.5/3.5" mechanical drives.

Why an SSD?
SSDs are flash-based drives that offer greater reliability and faster performance than traditional hard drives.
SSDs are storage devices that utilize non-volatile (do not lose data when power is removed) flash memory for computing applications that usually rely upon a mechanical hard disk drive.
SSDs are designed as industry-standard drop-in replacements (via a SATA connection) for hard drives. They make ideal hot swappable backup or portable drives.
Consisting of memory chips, a controller, connectors, and a board, SSD has no moving parts. This creates greater stability by eliminating the mechanical delays and failures associated with a conventional magnetic hard disk.
SSD Drives are commonly avalaible in 2.5" and 1.8" formats. 2.5" is mainly for Computer use at present with the smaller standard used within portable smaller devices.
What are the advantages of an SSD?
The continuous motion generated by multiple moving parts creates heat, which is a leading factor in hard drive failure. In fact, hard drives are one of the notebook components most likely to fail.
As an SSD has no moving parts, heat dissipation and noise are reduced or eliminated, resulting in a very rugged and reliable offering compared to a mechanical hard drive.
SSDs also have extreme shock and vibration tolerance, and their operating temperature ranges meet or exceed that of standard hard drives.
Increased power efficiency
Have you ever had your notebook battery die during a presentation? With no moving parts, SSDs require less power, improving battery operating time in notebook PCs and other portable electronic devices.
Without the moving mechanical parts that cause latency issues, SSDs are not impeded by spin-up, seek time, or rotational latency. This equates to faster boot times, faster application loading, and greater overall system responsiveness. Via SATA 2.0 interface, the 2.5-inch SSD offers a host data transfer rate of up to 3Gb/s, backward-compatible to SATA 1.5Gb/s.
With no spinning parts, SSDs provide for silent operation, similar to that of a standard USB flash drive rather than the constant, noisy humming of a mechanical hard drive.
Reduced heat dissipation
Hard drives dissipate high levels of failure-inducing heat due to the parts necessary to operate the hard drive (such as the spinning platter).
In contrast, SSDs produce little-to-no measurable heat because they have no moving parts, thus helping keep notebooks operating cooler.
Enjoy increased mobility with a lighter-weight SSD, which weighs less than a traditional mechanical drive.
