SSD vs HDD

MacBook Air (the world's thinnnnnest notebook) now uses SSD.
SSD = Solid State Drive
1. chips, no magnets, no motors.
2. a bit similar to flash memory used in digital cameras, mobile phones.
3. faster data access.
4. use less power.
5. quiet

HDD = Hard Disk Drive
1. mechanical device
2. manyak bising...
3. lagi panas... boleh masak telur...
4. not stable... gerak sikit kena reboot !@#$%^&*?
5. size besar...

Well, the advantages of SSD mentioned above is theoretical only... but it's the way the trend moves.
Gua percaya SSDs will become more common and more popular as their capacities increase and their prices drop... so, it's not worth to buy it at the present time.
