ব্যাখ্যা
RAID
stands for
Redundant Array of Independent Disks
.
It is a data storage technology that combines
multiple physical hard disks
into a single logical unit.
The main objectives of RAID are
data redundancy, improved performance, and fault tolerance
.
By storing data across multiple disks, RAID helps
protect data from disk failure
.
There are several RAID levels such as
RAID 0, RAID 1, RAID 5, RAID 6, and RAID 10
, each serving different purposes.
RAID is commonly used in
servers, data centers, and enterprise storage systems
.
Thus, RAID refers to a system that uses an
array of independent disks with redundancy
.

ডেটা স্টোরেজ প্রযুক্তি
, যেখানে একাধিক হার্ড ডিস্ককে একত্রে ব্যবহার করা হয়।
RAID-এর মূল উদ্দেশ্য হলো
ডেটা সুরক্ষা, কর্মক্ষমতা বৃদ্ধি এবং ত্রুটি সহনশীলতা
নিশ্চিত করা।
একাধিক ডিস্কে ডেটা সংরক্ষণের মাধ্যমে
ডিস্ক নষ্ট হলেও ডেটা রক্ষা করা যায়
।
RAID 0, RAID 1, RAID 5, RAID 6 এবং RAID 10
—এই ধরনের বিভিন্ন RAID লেভেল রয়েছে।
RAID সাধারণত
সার্ভার, ডেটা সেন্টার ও বড় স্টোরেজ সিস্টেমে
ব্যবহৃত হয়।
অতএব, RAID বলতে
স্বতন্ত্র ডিস্কের সমষ্টি যেখানে ডেটা অতিরিক্তভাবে সংরক্ষিত থাকে
—তাকেই বোঝায়।
