כונני קשיחים (כונני דיסק קשיח, קושחאות) הם מכשירי אחסון דיגיטליים המשמשים לאחסון וקריאת מידע במחשבים. הם מורכבים מדיסקים מגנטיים הסובבים במהירות גבוהה וראשי קריאה/כתיבה המזיזים על הדיסקים לצורך קריאה וכתיבה של מידע.
כונני קשיחים הם הסוג הכי נפוץ של מכשירי אחסון במחשבים והם משמשים לאחסון מערכת הפעלה, יישומים, מסמכים, מדיה וקבצים אחרים. נפחם של כונני הקשיחים עשוי להשתנות מכמה גיגה-בייט עד מספר טרה-בייט.
אחד היתרונות של כונני הקשיחים הוא המחיר היחסית נמוך שלהם בהשוואה לסוגים אחרים של מכשירי אחסון. בנוסף, כונני הקשיחים מציעים מהירות גבוהה יחסית לקריאה וכתיבה של מידע וסיבוכיות עסקתם נמוכה.
עם זאת, כונני הקשיחים יכולים להיות רגישים לנזק פיזי המוביל לאובדן נתונים. בנוסף, הם עשויים ליצור רעש וחום במהלך פעולתם.
בסופו של דבר, כונני הקשיחים ממשיכים להיות אחד האמצעים הפופולר
