The Difference between HDD and SSD ~ InfoTech

Today i want To Share with you the difference between two HARDWARE HDD (Hard Disk Drive) and SSD (Solid-State Drive).
First of all i want to give You The important of HARD Drivers to us !!

A hard disk drive (sometimes abbreviated as Hard drive, HD, HDD or SSD) is a non-volatile memory hardware device that permanently stores and retrieves information. There are many variations, but their physical sizes are 3.5" and 2.5" for desktop and laptop computers respectively. Connect to the motherboard using an ATA, SCSI, or SATA cable, and are powered by a connection to the PSU (power supply unit).

What are the sizes of hard drives?

The hard drive is typically capable of storing more data than any other drive, but its size can vary depending on the type of drive and its age. Older hard drives had a storage size of several hundred megabytes (MB) to several gigabytes (GB). Newer hard drives have a storage size of several hundred gigabytes to several terabytes (TB). Each year, new and improved technology allows for increasing hard drive storage sizes.

What is stored on a hard drive?

A hard drive can be used to store any data, including pictures, music, videos, text documents, and any files created or downloaded. Also, hard drives store files for the operating system and software programs that run on the computer.

Now we're see The Most importing Stuff of the HD And uses. Soo second of all i want to show you The difference Between HDD and SSD !!!

HDD (Hard Disk Drive)

A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in arandom-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile memory, retaining stored data even when powered off.

The two most common form factors for modern HDDs are 3.5-inch, for desktop computers, and 2.5 inch, primarily for laptops. HDDs are connected to systems by standard interface cables such as PATA (Parallel ATA), SATA (Serial ATA), USBor SAS (Serial attached SCSI) cables.

SSD (Solid-State Drive)

A solid-state drive SSD, also known as a solid-state disk is a solid-state storage device that uses integrated circuit assemblies as memory to store datapersistently. SSD technology primarily uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives, which permit simple replacements in common applications. Additionally, new I/O interfaces, like SATA Express and M.2 have been designed to address specific requirements of the SSD technology.

SSDs have no moving mechanical components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives (HDDs) orfloppy disks, which contain spinning disks and movable read/write heads.Compared with electromechanical disks, SSDs are typically more resistant to physical shock, run silently, have lower access time, and lower latency.

As of 2015, most SSDs use MLC NAND-based flash memory, which is a type ofnon-volatile memory that retains data when power is lost. For applications requiring fast access but not necessarily data persistence after power loss, SSDs may be constructed from random-access memory (RAM). Such devices may employ batteries as integrated power sources to retain data for a certain amount of time after external power is lost.

And finally the Mix Between two Hardware SSD and HDD is The Hybrid drives or solid-state hybrid drives (SSHDs) combine the features of SSDs and HDDs in the same unit, containing a large hard disk drive and an SSD cache to improve performance of frequently accessed data.
