capacity	smaller	big
price
random access		general
	SLC : Ten million mlc:1 million times	unrestricted
in-disk array
working noise	none	there

anti-vibration	good	poor
data recovery	hard	Yes
Weight	Light	Heavy

HDD Selection:

HDD: Mainstream HDD SAN ,SATA,SSD (SAS SATA is a mainstream production environment using SSDs SSD, the most efficient, non-mechanical, electronic equipment, high price );

Speed:

• SAN 15000 Turn /M Current mainstream has 300G and G used to provide online servers, such as database services and related high concurrency services.

• SATA 7200-10000 Turn /M has 1T and 2T recommended to provide server data storage backup, not suitable for online high concurrent server storage, can cause server access too slow or service outage.

3 )SSD SSDs, which are small in size and expensive, are suitable for businesses with small data volumes and high concurrency at scale. Large data volumes, high concurrent business, will increase with the cost accordingly.

Some large internet companies, three kinds of hard disk in a server with the use of classified storage, in order to achieve the best cost-effective.
