SSD or HDD?

SSD is now the latest trend for storage but expensive over traditional HDD. A solid-state drive (SSD), sometimes improperly called a solid-state disk or electronic disk is much faster than traditional HDD by 2-10x depending on which model of SSD.

What are other advantage of SSD?

1. Less heat
2. Faster than HDD
3. More resistant to shock
4. More reliable
5. Lighter to carry

Save precious work time with the power performance of a Solid State Drive (SSD)—and leave the office early.
1. Speed Up Your Boot-Up
SSD knows that «go» means «go». Just turn it on and begin working in less than 30 seconds.
2. Zip through File Searches
Remember the last time you attempted a simple e-mail search using a Hard Disk Drive (HDD)? Now imagine crunching that time so it's 5x faster. That's the power of an SSD.
3. Trim File Transfer Time by Almost a Third
Transfer and copy files thirteen minutes and five seconds faster than usual—just enough time to give you a head start on rush-hour traffic.
4. Start Applications in Seconds
Need to make a quick ten-second edit before meeting with a client? SSDs load programs such as Adobe Photoshop and PowerPoint more than twice as fast as their HDD counterparts.
5. Double File-Compilation Power
Just because programmers sit behind a computer screen all day doesn't mean they're immune to slowness. An SSD boasts 2x faster file-compilation times than HDD.
6. Cut Downtime by Half
Routine maintenance tasks shouldn't disrupt your work flow. SSD cuts simple tasks such as virus scans by almost 50 percent.
7. Reduce Power Consumption
SSD requires less energy than a conventional HDD and can add an average of 30 minutes to battery life.
8. Master Multitasking
SSD smoothly handles multiple programs so you can crop photos and load game maps nearly 3x faster than with HDD.
9. Cut Video-Editing Time
Render video file clips at over 30 percent faster with SSD. You'll be able to edit quickly and move on to your next project in no time.
10. Take it Anywhere
For work that needs to extend beyond home or office walls, SSD exceeds expectations in handling shock, vibration, and temperature extremes. Go anywhere with it.

Disadvantage?

1. Less storage capacity (latest SSD is 500GB, but market availability is 32GB-256GB)
2. Expensive

Best use:

1. For laptops, who frequently travel from one place to another
2. For desktops, set as primary storage for OS and other application who needs faster access
