While building computer, you need to choose data storage devices. This is equally important like the processor, motherboard and memory. Well, there is no dearth of devices that could be used to store data in your computer system. Some of these are hard drives, CD and DVD writers, and USB/Firewire storage devices, etc. Now-a-days, the use of SSD is also very common. Hard drives are a very crucial piece of equipment. Here all the programs, operating system, and data are stored. CD writers, DVD writers and USB/Firewire storage devices are now also very popular. To choose the data storage properly, you should have some idea about them. To build computer you can get tech support from a computer repair service provider.

Lets start with the Hard Drives. In the realm of hard drive, ATA and SCSI are two data access standards. The ATA standard is also divided into two groups - Parallel ATA (PATA) and Serial ATA (SATA). The SATA standard hard drives are now commonly used. The reason behind its growing popularity is its excellent speed. With these types of hard drives, the user can transfer data with a speed of up to 150 MBs. To use SATA, it is a must to use a Serial ATA controller as well as a SATA drive and a SATA power cable.

While buying hard drives, you should consider the drive speed as well. A faster SATA drive allows faster data access. But the cost of these types of drives is a bit on the higher side. It is also important to consider the drive space as well. If you are building a computer for performing only office tasks like just working on MS Office and browse internet, then you dont require huge amount of storage. On the other hand, if you want to do a lot of graphics or video editing then disk space should be plenty.

Although introduction of DVD combo writers have reduced the importance of CD writers but still many computer users install both of them. There are two choices of CD writers - internal and external CD. For desktop computers, internal drives are widely used while for the laptops external one is the best choice.

DVD writers are now hugely popular as they allow much storage than CDs. A DVD allows you to store up to 4.7GB on a single disc which is a few times the amount of on a CD-RW disc. DVD drives could also be external and internal. Although there is wide range of DVD media formats out there but DVD writer is the most popular one.
