SSD hard drives VS SATA hard drives
As we all know that hard drives are the part of computer system which stores the data of computer. First we look into SSD hard drives.
SSD hard drives:
SSD stands for solid start drive
Physical work performance:
HDD have rolling disks and read/write heads which store the information where as SSD make use of microchips and data is saved in ROM or cache chips and one of the best things about it is that it does not contain any moving heads in it. So it makes it work less. The interface of hard disk drives is the same as HDD thus SSD easily replace them in most applications.
In the era of vacuum tube computers SSD came from two similar technologies, core memory and card capacitor read only store (CCROS). SDD were implemented in semiconductor memory for supercomputers. SDD were highly taken in hand because it makes expensive computers quite seldom use.
Power Backup System:
The fast growing technology of 2010 NAND based flash memory is used in SSD in which memory is retained without power. SSD helps the situations in which faster access is required and do not require permanent power supply with it, back up will be there after removing the power.
There is one drive which combines HDD and SSD on one unit and that is Hybrid Drive.
SSD have faster starting facility because it does not contain disks to spin for booting. It has fast random access because it does not need any seeking motion like hard disk drives. Plus it has silent functioning due to less physical work. It consumes less power than hard disk drives due to this laptop manufacturer keep them as an additional optional. Lack of physical work reduces the risk of mechanical failure.
This technology is immune to magnets. Its size varies according to the requirement. Writing/reading data is secure as less failure occur which means there is less chance of data damage. SSD can perform parallel reads on multiple sections of memory which decrease the seek time of hark disk. SSD are becoming popular in markets for notebook PC due to its less size and physical work.
Now we look into another disk drive called SATA hard drives.
SATA hard drives:
SATA stands for Serial Advanced Technology Attachment and these are the most popular drives that are being sold today. Only the newer computers from last two years accept SATA connections because they are specially designed for SATA drives. The older PCs don’t have facility to connect to SATA drives for this you have to get SATA adapter cards that helps it to plug into your older machine’s mother board into an empty expansion slot.
SATA hard drives are faster and perform much better than traditional HDD hard drives and are appropriate for high bandwidth applications. Like video editing and multiplayer gaming.
These hard drives come with small size unlike previous hard drives plus it use smaller and cheaper cables to connect to the computer. The length of these cables can also be up to three feet compared to eighteen inches of old traditional hard drives.
Easy to Switch:
One of the advantages of SATA hard drives is that they can be swapped easily, it means they can be connected/disconnected any time as required without computer power down but there are limits to this of course. While your computer is operating you should never disconnect your boot drive.
Some of the little advantages which make you think of using SATA are that cables are easier to plug in without damaging the delicate connecting pins on the drive and these hard drives are faster than external USB drives.
