Having a business using a website as a major promotional media would need a reliable web hosting service. Not only for the consideration of up time and availability, but now the speed is one of the main factors to get traffic from search engines, like Google. Therefore, you should consider using a SSD powered shared hosting. Because the SSD performance is much better than the conventional hard disk.
SSD: Solid-State Drive
SSDs have no moving (mechanical) components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives (HDDs) or floppy disks
In fact, today there are many shared hosting services that use SSD as a storage, there are only for cache and there is also a pure SSD hosting.
About the price, I guess you will not mind the price. Because there is no difference with the price of conventional HDD shared hosting.
The following is the best SSD on shared hosting services that I found if you are planning to migrate to a more reliable web hosting.
Note: The order does not determine the quality.
