1. Speed (RAID 0)

Set in high-performance mode (also called striped mode or RAID 0) the storage system gives you the power you need when you’re:

• Designing huge graphics and need a lightning-fast Photoshop scratch space.
• Recording large DV files while maintaining clean audio performance.
• Editing DV or HD video and want a smooth work flow with no dropped frames.
• Rendering complex 3D objects or special effects.
• Performing disk-intensive database operations.
• Driven to be the first geek on your block with a computer so fast it blows your
  socks off.

Why is RAID 0 so fast? It’s a bit complicated, but suffice it to say that two or more

What if your hard drive decides to enter the Elysian Fields in this very moment? Sure, you could simply get a new hard drive to substitute for the defective one with a quick run to your favorite hardware store. And with last night’s backup you might even reconstruct your installation quickly. But what if you don’t have a backup? The truth to be more like this: many users don’t even have a backup, or it simply is too old and thus useless for recovering any useful files at all. In case of real hard drive damage, only a professional data recovery specialist can help you – say bye-bye to your vacation savings!

Hard drive failure is especially disastrous for smaller…

1. Raid 1 Data Recovery FAQ

Q: What is the definition of a “RAID 1″ volume?
A: “RAID 1″ refers to a “Redundant Array of Inexpensive (or Independent) Disks” that have been established in a Level 1, or mirrored, drive set. A RAID 1 volume is a set of disk drives that are configured for data to be written to 2 volumes simultaneously. This configuration provides complete data redundancy in the event of a drive failure.

Q: What is meant by the term “mirroring”?
A: Within a mirroring (RAID 1) volume, the exact same information that is written to one disk is also written to a second disk, creating a “mirror image”, or clone, of the orginal hard drive.

RAID
Redundant Array of Independent Disks, a collection of two or more disks working together in an array. Mylex RAID controllers implement this technology to connect up to 15 SCSI devices per channel. The different forms of RAID implementation are known as “RAID levels.” See also Berkeley RAID Levels, Disk Array, and RAID Levels.

The system manager or integrator selects the appropriate RAID level for a system. This decision will be based on which of the following are to be emphasized:

• Disk Capacity

• Data Availability (redundancy or fault tolerance)

• Disk Performance
