The various types of hard disk capabilities

How many external hard disks do you have?

External storages are so affordable these days that we can have one for documents, one for movies, one for music files and another one just to install and run applications externally.

Having too many external hard disks can be a problem as the disks can sometimes be misplaced. Another challenge, we might have difficulty trying to identify which hard disk contains what files. Unless you tag your disks properly, it can be troublesome to hook up several disks just to find the right file. Photo my matsuyuki

The technology behind hard disk storages advance very quickly. Few years ago, if you have a 160 GB hard disk, it is something to shout about. Today, it becomes a standard hard disk capacity. And in the coming years more and more solid state drives (SSD) will emerge in the market. If you’re not familiar with SSD, it is basically a data storage with no moving parts in it thus providing the following benefits as compared to a normal hard disk:

• Less fragile
• More silent
• Lighter
• Faster
• Lower power consumption

Hey, looks like SSD is really cool, what’s the catch? It’s really expensive right now. But by how much? Wikipedia – SSD has the answer. Another disadvantage of SSD for now is that the capacity is usually much smaller.So that’s for SSD. Any other new technology related to hard disks?

Yes, and it’s the Western Digital’s My Book Mirror Edition.

These new drives allow users to set up RAID 1 or RAID 0 providing them with fully secure backups of their data. So it’s like a backup feature within your external hard disk. What it does is that it automatically mirrors your valuable data for extra protection. Just in case one hard disk fails due to whatever reason, the other hard disks has it all.

This external storage comes in either 1TB or 2TB capacity.

Although I’m not an owner of this device, I can say that the huge storage space as well as the mirroring capability definitely attracts my attention. However, it does look a bit bulky so it may be more suitable for desktop environment rather than to carry it around in my notebook bag.
