It wasn't long ago when just the thought of building a reliable server caused a loud sound in my head... Much like the sound of bathtub water draining, but instead of water it's dollar bills going down the drain. In the past, you could easily spend 5 to 10k on a file server, especially if you wanted to store mass amounts of data. Over the years the costs of building a server has gone down tremendously, however enterprise level data storage can still be very expensive, especially SCSI or Small Computer Systems Interface hard drives. In the past, if you wanted speed and reliability in a server, the only way to go was SCSI. SCSI interface hard drives were, and still are, very fast and reliable, but the days of SCSI's reign as king are numbered. This is due to less expensive and just as reliable methods of storing such massive amounts of data. One of the methods that has been around for quite some time is the Serial ATA interface hard drive. However, you just can't plug in any old SATA hard drive and expect it to last in a demanding 24/7 environment. With enterprise level SCSI hard drives you could expect years of 24/7 operation with very little or even zero failures. Normally, standard off the shelf desktop hard drives just are not designed to take that sort of punishment. This is where the Barracuda ES (Enterprise Storage) hard drives come in. Now that same bullet proof reliability we've come to expect from SCSI is available in a less expensive form.
