will transparently move sub-file-level data between two tiers based on how often the data is accessed. As a result, storage tiers can dramatically improve the performance of these data by moving the most commonly used ("hot") data to SSD storage without compromising the ability to store large amounts of data on an economy-type HDD.write-back cache.

In March of this year, we introduced SSD-based Elastic Block-level storage for Amazon EC2 instances. After a few months of release, this new method of choice, known as general-purpose storage (SSD), has accounted for 90% of the newly created EBS volumes, we learned from customers' feedback that they like this consisten
The SSD (Solid state disk or Solid Drive) is also known as a solid-state drive, a new generation of hard disk products that use flash pellets as storage components. SSD hard disk has the characteristics of high speed and security, but it is hindered by its wide application because of its expensive and limited capacity. However, with the continuous downward flash
