The Hd And Cd/Dvd Roms

Posted by driveout on January 17, 2011

In this post I will cover two parts as the basics about them are very brief so theres no need to go in depth. Its like killing two birds with one stone lol. Anyway lets proceed, I will cover the Hard Drives first.  There are a few different speeds of hard drives 5400 rpm, 7200 rpm, 10000 rpm, and 15000 rpm. The normal HDD run at 5400-7200 rpms if anything go with 7200 as its faster. As for laptops alot of them still use 5400 rpm HDs. The most used one for basic use computers is 7200 rpms. Keep in mind there are other speeds as well but these in my opinion are the most used. The other Hard drives are SCSI which run from 10000-15000 rpms, yes they are quick but also expensive, louder and they are mostly used for servers. Lastly there is also the new Solid state drives which have no moving internal parts. On those you just look at the transfer speed as it does not have any rpms. That said the price is a little on the heavy side. Moving on theres two forms of Hard drives one is IDE and the other SATA. Difference is SATA has higher rpms meaning higher transfer speed. IDE are the older drives, either way the cable for IDE is bigger as for SATA its nice and small.

Thats enough for the speeds and types i dont want to overwhelm you with information all at once. I keep forgetting its a beginners guide, but one more thing to remember is how much space do i need ? Well thats a choice you have to make I would say for basic use any where from 120gb to 200gb should be more than enough. For hard core users 200gb and up for sure.  Alright I am almost done, last thing to cover is the Cd/dvd roms.

There are many to choose from, such as reader only, writer only or both reader/writer. That goes for all CD, DVD and Blu Ray Roms. Which ever one you choose is up to you but its better to get reader/writer combo. Like with anything there are different speeds you can get, a few examples are 6x, 8x ,12x usually the faster the better. This concludes our last post of the Beginners Guide i hope everyone has enjoyed this and have learned something.

Stay tuned as there will be a Guide coming out on how to assemble a computer which includes a video tutorial 🙂
