SSD Vs HDD

INRODUCTION

1. Solid State Drives are Technology of the Day.

2. New Technology = Expensive

3. Solid State drives with 64 GB capacity cost almost $180+

4. HDDs record data by magnetizing ferromagnetic material directionally, to represent either a 0 or a 1 binary digit. While SSDs use non-volatile flash memory.

	HDD	SSD
Reliability of the drives	HDD drives use mechanical parts are there lifespan is limited.	SSD using flash memory can sustain almost 100,000 write cycles per write cell.
Read/Write Speeds	Rotating disk is around 5,000 – 10,000 micro-seconds.	The typical access time for a Flash based SSD is about 35 – 100 micro-seconds. Flash-based SSD approximately 100 times faster than a rotating disk.
Data transfer rate	HDD data transfer rate at the rate of 80 megabytes per second typically.	SSD data transfer rate at the rate of 170 megabytes per second typically.
Audible noise	HDD have audible clicks and crunching sounds.	SDD drives are often quieter because they have no mechanical parts.
Vibration	HDD drives can withstand up to 350 Gs while operating and 800 Gs when turned off.	SSD drive can sustain up to 1,500 Gs of shock before sustaining damage or a drop in performance.
Reliability	Shock, vibration, and temperature ratings of HDDs cannot comply with military standards.	SSD have the ability to deliver unnerving performance in extreme conditions making it to play a vital role in military operations, defense, aerospace or aviation applications. Military applications require, in most cases, an operating temperature range of -60°C to +95°C.
Power Play	HDDs have high power than SSD.	SSDs have low power consumption over HDDs
Cost Considerations	traditional hard drives cost about 20 to 30 cents per gigabyte	The cost of SSD are typically $3 per gigabyte

Conclusion

If you can go for an SSD because your pocket makes it easy. Then you should definitely choose for SSD otherwise wait at least 3 to 5 years when there prices drop.
