What is RAID Storage?

RAID storage refers to "Redundant Arrays of Independent Disks", and is the practice of saving information on a server which then safeguards your information by replicating it on several disks which are then saved on the server. If one of the disks in the RAID fails, your data will be okay since the other disks have copies of the identical information.


You can learn more about computers at WikiPedia.

Folks who could reap the benefits of RAID include any person who uses their computer system to store a substantial amount of data which they would not like to lose. If you are currently storing your information on a standard drive, you may lose everything if your drive crashes.

If, right now, you are just saving your data to your hard drive, (or even to an external hard drive, zip drive, etc), you are in great danger of losing all of that information.  Sure, there are data recovery programs out there but, for the most part, they are very expensive and are generally only able to recover bits and pieces, (if any) of your data.  The best way to keep from losing your information is to back it up.

When you've got any important information on your computer system, it's essential that you back up your files.  A RAID system is virtually the easiest way to protect your computer data from accidental loss or damage. RAID's multi-disk method ensures that your information is safeguarded from loss.

NAS Storage is simply a RAID system which makes use of a Network Attached Storage device, (that's the "NAS" part).  As with other RAID systems, NAS helps you safeguard your information in the event of a drive failure.  We would all like to believe that our computers and other electronic devices will last forever, but sooner or later, they will all fail or crash.  They are simply not made to last forever.  The sooner you back-up your info the better.  Because maybe not today, and maybe not tomorrow, but someday your drive will fail.

What is JBOD?

JBOD stands for "Just a Bunch of Disks" or "Just a Bunch of Drives," which is essentially what it is.  JBOD allows folks to simply connect drives to their computer.  Unlike RAID and NAS RAID, JBOD simply adds extra connections without the redundancy of backups. The nice part about JBOB is that it allows you to handle odd-sized drives as though they were a single unit.  For example, a 30GB drive and a 10GB drive would register as one 40GB drive.  That makes JBOD a great choice for folks who have a lot of odd-sized drives around.

A durable display system mounted on metal racks is known as a Rack monitor or Rackmount LCD. This revolutionary product is attached to an aluminum or steel frame with regularly-spaced holes which are then connected to the matching holes in the steel bars on a rack. This enables the display unit to be securely attached to the rack.

Rackmonitors can be found in numerous sizes and the distinctive structure of the Rackmount LCD efficiently utilizes rack-mountable room which makes it a great option for environments with confined spaces.
