The hard drive failure is the usual problem with the computer, but other SSDs. The flash memory chip can usually write / erase 300,000 times.
SSD and HDD, select drive do?

The hard drive failure is the usual problem with both desktop and laptop. Most dangerous consequence is the loss of many precious data users. With HDD, an electromechanical device, through the years of the operation will wear down and lead to malfunction. Optimal working time for HDD is about 4 years.
SSD drives to other applications. The flash memory chip can usually write / erase times and the 300,000 chip flash memory lifetime best times of up to 1,000,000 write / erase. In addition, the SSD manufacturers also use other measures to prolong life. Thus, an SSD can be used well for many years, but also depends on the size of the disk.
Speed
Average access time of SSDs is from 3.5 to 10 micro seconds remaining HDD takes 5-10 milliseconds. Easy to find, faster speed SSD HDD to a hundred times. But the question is unsurpassed in speed of SSDs benefit while the computer system can not support that speed?
The "evolution" of the central processor (CPU) has developed far beyond the data storage system. So much HDD when will "hamper" performance "potential" of the system by not keep up the processing speed of the hardware, especially the CPU.
Replacing HDDs with SSDs, system performance will definitely be improved.
Size
Developed and produced with the aim of gradually replacing the traditional HDD to SSD also has two types, standard size 2.5 inch and 3.5 inch. Similarly, a 2.5-inch SSD is used primarily for laptops, and a 3.5-inch drive for desktop - desktop, storage systems for all server machines. But size and light weight of SSDs than HDDs, thus more suitable for compact systems.

The reliability
In terms of reliability, HDD inferior to solid-state drives. The use of read / write heads and the mechanical motion of the spinning disk blade element reduces the HDD reliability. In the mobile environment applications that require high security for data, SSDs will definitely be a better choice. SSDs are shock resistant and have good strength. These are the advantages that many areas have specific characteristics such as the military option these drives. Especially SSDs can also be stored in extreme environments with temperatures from - 60oC to + 95oC.
Power consumption and heat generation
Compared to HDDs, SSDs are more efficient because no additional power required to drive the moving blade and disk read / write heads and cooler. Therefore, this option is more suitable for the needs of data storage company, in addition to also save more without the cooling system, cooling costs.
Price
With many advantages and superior features, SSD therefore also more expensive than traditional HDD. This is a competitive advantage that HDD is still the main choice to use, and its high price is also not a major hurdle that SSD can be widely used. This new type of burner is mainly used in the military field and the industry requires high level of data integrity.
Analysts have said that the price gap between traditional hard drives and solid state drive SSD will become increasingly narrow. Besides, the big names in the industry drives are built of poured money and effort into research production, improve memory SSD to replace HDD prospect is not far away. But now, the advantages and special features of SSDs still can not "beat" advantage of cheap HDD.
