Nowadays most people use laptops and pcs for their computing needs, when you purchace you should take good decesion while checking configurations. Now new brand models come with SSD type hard drives. So do not confuse on that now we are going through about differences of SSD and HDD drives.
What is an HDD?
Hard Disk Drive(HDD) were first introduced by IBM more than 60 years before. Basically HDD uses magnetism concept to store data on a rotating platter. HDD performs depends on spinning of platter. Today Laptop drives spin at either 5400 RPM (Revolutions per Minute) or 7200RPM, some server based platters can spin at up to 15,000 RPM. The major advantage is capable of storing more data very cheaply. Cost per gigabyte is only around $0.10 / GB for HDD drives today. If you want cheap storage and lots of it, using a standard hard drive is definitely the more appealing way to go.

SSD stands for Solid State Drive. Which is like a USB memory. Data is stored in microships. The main difference is SSD much faster than HDD. A typical uses NAND based flash memory. An SSD does not have a mechanical arm to read and write data, which instead relies on (an embedded processor) a controller to perform a bunch of operations related to reading and writing data. This is important factor in speed of the SSD.
Eventually SSD looks like compact and which is very ease to replace HDD

SSD Bottom Side[/caption]SSD Vs HDD
Power Draw / Battery Life Less power draw, averages 2 – 3 watts, resulting in 30+ minute battery boost More power draw, averages 6 – 7 watts and therefore uses more battery
Capacity Typically not larger than 256GB for notebook size drives Typically 500GB – 1TB for notebook size drives
Bootup Time for Windows 7 Around 22 seconds average bootup time Around 40 seconds average bootup time
Noise No sound Audible clicks and spinning can be heard
Heat Produced Lower power draw and no moving parts so little heat is produced HDD produce some heat, due to moving parts and higher power draw.
Failure Rate Mean time between failure rate of 2.0 million hours Mean time between failure rate of 1.5 million hours
File Copy / Write Speed Generally above 200 MB/s and up to 500 MB/s for cutting edge drives The range can be anywhere from 50 – 120MB / s
File Opening Speed 30% faster than HDD Slower than SSD
Magnetism Affected An SSD is safe from any effects of magnetism Magnets can erase data
which drive is best for you:
If you need lots of storage capacity, over 500GB
If you don’t want to spend much money
If you don’t care too much about how fast a computer boots up or opens programs
Then definately go and get a hard drive (HDD).
If you are ready to pay for faster performance.
If you dont mind about limited storage.
then go and buy SSD.
