HDD Vs. SSD
The traditional hard drive is the core nonvolatile storage on a computer. (information on it doesn’t “go away” when you turn off the system)
A hard drives is essentially a metal disc with a magnetic coating that stores your data in a series of binary codes, there is a read/write head on an arm which accesses the data while the discs are spinning.
An SSD does functionally everything a hard drive does, but data is instead stored on flash memory chips that retain the data even when there’s no power present.
The chips can either be permanently installed on the system’s motherboard (as on some small laptops and ultrabooks), on a PCI Express (PCIe) card, or in a box that’s sized, shaped, and wired to slot in for a laptop or desktop’s hard drive.
These flash memory chips are of a different type than is used in USB thumb drives, and are typically faster and more reliable. SSDs are consequently more expensive than USB thumb drives of the same capacities.
However at http://pc-tec.co.uk/ we have arange of SSD drives that start from as little as £46.99.
One of the other benefits of SSD drives is that some machines configure them as part of the PC’s cache RAM, thus increasing the speed of browsing and data streaming.
