Speeding up a PC (Part 3)

In the prior two posts I have talked about increasing PC speed by changing the CPU and increasing the amount of RAM. In this final part I will focus on the Hard Drive.

The Hard Disk Drive (HDD) is the component of the computer used for storage. HDD's are measured by size in terms of Gigabytes (GB) or Terabytes (TB). A 750 GB hard drive is smaller than a 2 TB drive. An HDD has a physical disk that spines at a certain speed; most common are 5400 rpm or 7200 rpm. The disk spins as it reads and writes to the disk. The faster the rpm the faster the drive reads/writes. These drives can be noisy, run hot and be less energy efficient. 

New on the market are Solid State Drives (SSD). SSD's are different from HDD's in that they do not have a physical disk. As a result SSD's are quiet, run much cooler and are the most energy efficient. SSD's dramatically increase PC speed! We can measure this through read/write speed. I recently converted a PC from a 120GB HDD to a 120GB SSD. I ran a read/write speed test with both drives and the result are astonishing! I used a program called Crystal Disk Mark on each drive I preformed a 1GB test. The 120GB HDD read was 22.26 and the write was 36.03. With the new SSD the read was 211.0 and the write was 171.0; the read score was nearly 10 times faster!!

A SSD upgrade for a computer is a little more expensive than RAM; depending on the capacity it can average about $150. When deciding to purchase an SSD it is important to look, not only, at the capacity but the read/write speed as well. 

Intel makes some very good Solid State Drives; find more info at: http://www.intel.com/content/www/us/en/solid-state-drives/solid-state-drives-ssd.html
