RAID Technology
- High speeds for audio/video professionals
- Greater capacity and reliability for servers
- Data security thanks to hot-swappable drives
A RAID configuration allows several hard drives to act as a single unit in various ways, such as striping or mirroring. Some potential advantages of RAID are greater capacity, reliability, speed, throughput, or better data integrity (or a combination of these), often at a more affordable price than comparable single drives.
Throughout LaCie’s line of RAID solutions, there are various RAID levels, each with its own limitations and advantages. Choosing the right RAID level depends entirely upon the user’s needs.
Common RAID Levels
- RAID 0: Striped Set – (or Striped Volume) splits data evenly across two or more disks with no parity information for redundancy.
- RAID 1: Mirrored Set – creates a mirror or exact copy of a set of data onto two or more disks, providing protection against a single disk failure.
- RAID 0+1: Mirror of Stripes –a RAID level used for sharing and replicating data among multiple disks.
- RAID 5: Striped Set With Parity– requiring at least three disks, it uses block-level striping with parity data distributed across all disks – an ideal way to get affordable redundancy.
- RAID 10: Stripe of Mirrors – sometimes called RAID 1+0, it’s similar to a RAID 0+1 but reversed since RAID 10 is a stripe of mirrors.
- Concatenation: JBOD – "Just a Bunch of Disks" is a popular way to combine multiple disks into a single virtual drive without the RAID benefits.
