Q

Give a description, a benefit, and what does it stand for.

A

Solid-State Drives (SSDs)
* Description: SSDs use flash memory to store data, unlike traditional HDDs that rely on spinning disks and moving parts.
* Benefits:
○ Speed: SSDs are significantly faster than HDDs due to instant memory access.
○ Reliability: Without moving parts, SSDs are less prone to mechanical failure.

Q

RAID Storage

A
  • RAID (Redundant Array of Independent Disks) is a technology that combines multiple storage devices into a single unit for improved performance and data redundancy.
    1. RAID 0:
      ○ Purpose: Enhances performance by splitting data across multiple drives. No data redundancy (no copying).
    2. RAID 1:
      Purpose: Mirrors data across multiple drives, providing redundancy and improving read speeds.
