Hard Disk ek storage device hai jo data ko store karne ka kaam karti hai. Ye computer ya electronic devices mein data ko save rakhne aur retrieve karne ke liye use hoti hai. Hard Disk ek non-volatile memory device hai, jiska matlab hai ki jab tak power supply hai, data store rahega.

Hard Disk ko generally two types mein classify kiya ja sakta hai:

  1. HDD (Hard Disk Drive): HDD ek mechanical storage device hai. Isme ek rotating disk hoti hai, jise platter kehte hain, jise read/write heads access karte hain. Data ko magnetic particles ke form mein store kiya jata hai. HDDs traditional storage devices hain aur generally zyada storage space provide karte hain lekin unki speed SSDs se kam hoti hai.
  2. SSD (Solid State Drive): SSD ek newer technology hai. Isme moving parts nahi hote, aur data ko flash memory chips mein store kiya jata hai. SSDs faster hote hain aur shock resistant bhi hote hain kyunki unmein koi moving parts nahi hote. SSDs compact form factor mein available hote hain aur aaj kal laptops, desktops, aur even servers mein bhi commonly use hote hain.

Inme se konsa hard disk use karna behtar hai, ye use case par depend karta hai. Agar aapko fast performance chahiye aur aap afford kar sakte hain to SSD ek accha option ho sakta hai. Agar aapko zyada storage space chahiye aur cost a consideration hai to HDD ek cost-effective option ho sakta hai. Bahut se log bhi apne systems mein dono types ke hard disks ka combination use karte hain, jise hybrid storage bhi kehte hain.
