When you have to back up or store a huge amount of data and one single hard drive is not enough,it’s time you should consider a external raid enclosure

external raid enclosure support two or more separate hard drives,that can make enough space for you to store a large accounts of data.for example,the Dual-Bay RAID Enclosure,there are some more options for setup:

RAID 0: If you config the enclosures to “RAID 0 supported”,then the two installed Hard Disk Drives will change to one large “virtual” disk.such as after  you install 2 single 1TB SATA Hard Disks and at last you will got a new “virtual” Diskthat have 2TB space.

RAID 1: Alternatively if you config that the two installed Hard Disk Drives to utilize “RAID 1″ (Mirroring Mode) then any data  saved to the hard Drives in the enclosures will be automatically mirrored to the second hard drive. in fact one of the hard disks in the enclosures becomes the primary back up and the another becomes the secondary back up. any Data that copied or “mirrored” to the secondary back up is totally copied automatically.

if the data you using is very important,just use the RAID 1 mode,it’s more safety for back up your important data.

external raid enclosure shows how far this kinds of products have come over the years and reflected how much data that we are now stored or even should to be stored regularly.

there are lots of external raid enclosure have already on the market as more people have huge data such as digital photos,music,vidoes and movies to store in their desktop.such as  Maxtor, Freecom and Lacie and more. but these “solution” also include both the Hard Disk and the enclosure.if you already have hard disks from your old computers then its more cheaper to buy a Hard Disk Enclosure and use the Hard Disks you have for the enclosure.

externa enclosures take a internal hard disk, and they change it to exterior hard disk. That was useful if you want some additional place for your desktop, or if you need the access of your hard drive of your laptop from your computer. for these reasons, you should learn all these to know in order to select correct for you.

You should check the size of your hard drive of your computers.if you use an Laptop,the hard drives use to be 2.5 inches , even some laptop are 1.8 inches.for a Desktop, the hard drives almostly are 3.5 inches. You should use the same size in your hard drive with your enclosures. but there are some other types like 5.25 inches,which was used in housing cd/dvd drives,should also have 3.5 inches hard drives,and some of 3.5 inches enclosures also can fit for 2.5 inches hard drives.

You should check the types of your hard drives.IDE,PATA OR SATA? You Should buy a enclosure that support the type of your hard drive.IDE/PATA are older types and the SATA have faster transfer rates.if you have more than one SATA hard drives,find some external raid enclosure for faster speed and safety.

You should check if you need a fans for you enclosures.usually the enclosures have built-in fans to make sure that the hard drives works nice and keep cold.but on the other hand,it could bring your some more noise.so if you didn’t like the extra noise,don’t get a enclosure with a fan

What material to use.there are some kinds of materials for enclosures,Plastic,aluminum and metal.be aware those enclosures made of plastic,to keep your hard drive cook,aluminum or metal enclosures can really works better than the plastics.

The power.Get a enclosures that use a AC adapter for power.USE can used in the connections,but it’s really dangerous and unstable for those power the drive only with USB port.

So you can easily find the external enclosures that you need.other advice,if you have more hard drives,want more fast speed and stable,just choose an external raid enclosure.

An external raid enclosure is a shell that can let you insert an other hard drive of Your PC or laptop for use externally. How to used it depends on you after installation. as the Enclosure kits provide protection to a bare hard drive,so it can work all the time.

there are two hard drive size of enclosures,for a Laptop size,2 and 1/2 inches,and for a desktops size:3 1/2 inches.for Connections? PATA and EIDE are too old, the SATA have faster transfer rates. so there some kinds of sata external enclosures include external raid enclosure

• 1, Massive Storage Enclosure

This kinds of  external enclosures accommodate huge numbers of  hard drives, Can be use  for massive storage capacity.  High-performance RAID 1, RAID 5 and RAID 0  – perfect for you if you have a  HD video editing workstation.

• 2,SATA Port Multiplier Enclosure – Software RAID and  Hardware RAID

This kinds of  external raid enclosure perfect for built in SATA Port Multipliers which support Software RAID or Hardware RAID control and provide a high performance connections between one port or multiple hard drives.  Software RAID enclosure can be used as individual drives (JBOD) or as RAID 1, RAID 5 or  RAID 0 arrays.  Hardware RAID enclosure have built in RAID controllers,so it taking the load off of the computer CPU.
