sata hard drive vs ssd.
SSD drives - Introduction.
As HDD drive SSD is also a storage device for the computers and all data is stored in integrated circuits.
SSDs stand for SOLID STATE DRIVE.
It is compact in size and also reduces dramatic access time for start up.
SSD Drive is more expansive than HDDs per amount of storage.
SSDs for computers are available in 120 GB to 30.72 TB capacities in the market.
It is also called as flash memory.
It was first introduced in 1991 SSDs drive basically works on the algorithm of semiconductor devices and data is stored in the circuitry system.
Nowadays, there are several computers are available in the market having great prices for SSD CPU. As time moves on and technology improves SSDs would become more and more cheap and price would definitely cut down.
sata hard drive(HDD) - Introduction.
HDD stands for Hard Disk Drive. It is based on the technology of magnetic writing on the disk installed in a hard casing. HDD drive stored data in the non- volatile data storage format. In the modern era these drives are available in rectangular shape.
Don’t be confused of the RAM OR ROM memory as these are the criteria as how data would be stored on the computer. RAM means Random access memory or sometimes it is called as Volatile memory i.e. data stored in these devices are saved only when the computer is running and erases back whenever computer turned off.
Internal Hard drive connected to a cable (ATA, SCSI or USB) and power cable connected to the power supply.
While ROM is a Read only Memory means data stored in the storage device would saved permanently i.e. data would not lost instead of shut down of the computer. This ROM is also called as non- volatile memory and hard drives are the common example of the non- volatile memory storage device.
Mostly HDDs are manufactured by 224 companies while Seagate, Toshiba and Western Digital have more impact on the global market. HDDs are available in 3.5 inch for desktop and 2.5 inches for laptops.
It is connected by the PATA (Parallel ATA) or SATA (Serial ATA) cable connection, USB or SAS (Serial attached SCSI) cables.
It takes time to start up your system as it have mechanical hardware means physical parts and they would take time to start up such as disk , electric motor, etc. So, therefore it is slower in speed as compared to SSD drives.
The very first hard drive was introduced by IBM (International Business Machine) in September 13, 1956. And also IBM developed a first removable Hard disk of size 2.6 MB storage capacity.
