Hard drive Explain

Dosto aap ne computer use kart time kabhi na kabhi socha hoga ki ye data konsi memory me save hota hai,
To jab bhi aap apne computer me koi bhi file save karte ho to vo file aapke computer ke hard drive me save hota hai
To aapko janna hai ki
hard drive kya hai
kese kam karti hai
kitne type ki hoti hai
to pehle jante hai ki hard drive hoti kya hai

HARD DRIVE KYA HAI

Hard drive ko hard disk ya HDD bhi kaha jata hai

Hard drive ek physical disk hai,hard drive apne computer ka sabhi data store karne ke liye use hoti hai
Hard drive ke andar disk ghumti hai jitni fast disk ghumti hai utni speed se hard drive data ko store karti hai
Hard drive ki ghumne ki sped ko hum rpm(revolution per minute) me naapa jata hai,
Jyadatar hard drive 5400rpm ya 7200rpm ki hoti hai
7200rpm ki speed ki hard drive ki speed 5400rpm ki hard drive ki speed se jyada tez hoti hai.

HDD (HARD DISK DRIVE) AUR SSD (SOLID STATE DRIVE) ME DIFFERENCE
Aapne laptop lene se pehle kabhi na kabhi HDD aur SSD ke bare me zaroor suna hoga vese ye dono hi data store karne ke liye hoti hai
Magar aap laptop lena chahte hai to aapko HDD aur SSD ke bare me jan lena chahiye  to pehle hum jante hai HDD aur SSD kya hai,
HDD aur SSD me kya difference hai, konsi hard drive kya fayde hai aur kya nukshan hai, aur konsi acchi hai,

1.HDD- HARD DISK DRIVE
Hard drive ek physical disk hai jinke andar dvd ke jaisi moving plate hoti hai, in plate me hi data store hota hai hai
Aur unke jaise  bahot saare ploters hote hai, aur usme ek revolving head head hota hai jiski madad se data in ploters me se read kiya jata hai

HDD- (HARD DISK DRIVE) KE FAYDE KYA HAI
  • Jyada capacity ki HDD aasani se market me mil jati hai
  • Hard drive bahot cheap hoti hai
  • Kahi se bhi aap purchase kar sakte hai


HDD- (HARD DISK DRIVE) KE NUKSHAN KYA HAI
  • High power use karti hai
  • Perfomance accha nahi milta
  • Size bada hota hai isliye weight bhi jyada hota hai
  • 5-6- saal baad problems aati hai varna performance acchaa nahi milta kyunki unke andar

2.SSD- (SOLID STATE DRIVE) KYA HAI


SSD ek tarah ki chip ya memory card ki tarah hai, usme koi moving part nahi hota.
Jo bhi data hai vo sara chip me hi save hota hai


SSD- (SOLID STATE DRIVE) KE FAYDE KYA HAI
  • Low power use karti hai
  • Size chota hota hai isliye weight bhi kam hota hai
  • Usme koi moving parts nahi hota to kharab hone ke bahot kam chance hai
  • Speed bahot jyada hoti hai bahot accha performance milta hai

SSD- (SOLID STATE DRIVE) KE NUKSHAN KYA HAI
  • HDD ke mukable bahot jyada mahengi hoti hai
  • Jyada capacity ki ssd bahot kam milti hai
  • Normal market me aassani se nahi milti

SSHD KYA HAI
ye hdd aur ssd ka combination hai jo dono ko mila kar banayi jati gayi hai iska full form “solid state hard drive” hai ye aapko naye laptops me hi milegi aur vo bhi kisi kisi laptops ke saath me
aap ssd me operating system install kar sakte hai aur hdd me apna data save kar sakte hai. isse aapka computer fast work karega ssd ki sped bahot jyada hoti hai aur aap bade aaram se apne computer par kam kar sakte hai
agar aap naya laptop lena chahte ho to kosis kare ki usme ssd ho, aur agar aapke pass purana desktop ya laptop hai to app usme sshd ya ssd laga kar uski speed bada sakte hai

EXTERNAL HARD DRIVE KYA HAI

External hard drive computer me usb port se lagayi jati hai isliye usse external hard drive kaha jata hai,
USB se connect karne ke karan internal hard drive se mukable thoda slow performance milta hai

HARD DRIVE AUR RAM ME DIFFERENCE
Hard drive data ko store karne me use hoti hai,  Lekin ram hard drive ki files ko chalane ka kam karti hai
Jab hum computer ko band karte hai to ram ka sabhi data remove ho jata hai,
Lekin hard drive me computer band hone par bhi data remove nahi hota
