מערך RAID

שיטת אחסון נתונים מתקדמת בה משתמשים בכמה דיסקים קשיחים על מנת לשפר ביצועים, אמינות והגנה על המידע.

סוגים של מערכי RAID:

RAID 0:

משפר ביצועים על ידי חלוקת הנתונים לרצפים באופן מקבילי על כמה דיסקים.

אין הגנה על המידע – תקלה באחד הדיסקים עשויה לגרום לאובדן כל הנתונים.

RAID 1:

מעתיק את אותם נתונים על יותר מדיסק אחד, מספק הגנה כפולה על המידע.

פחות יעיל בביצועים אך מציע הגנה גבוהה יותר על הנתונים.

RAID 5:

שומר על נתוני ביטים במחסנית נתונים עם בירורים, מספק הגנה וביצועים טובים.

עמידות בתקלות תוך כדי שימוש יעיל בנפח האחסון.

RAID 10 (RAID 1+0):

שילוב של RAID 1 ו-RAID 0, מספק הגנה כפולה וביצועים משופרים.

דורש יותר דיסקים, אך מציע אמינות גבוהה וביצועים מהירים.
