The advantage and disadvantage between the Storage of a Server

In recent years, the server's configuration has been greatly promoted, not only the CPU and RAM, the storage is also included. As we know, there are too different types of storage, one is SSD and the other is HDD, there are also some differences with them, for example the reading and writing speed, the SSD is 3-5 times faster than the HDD , which can reach at 400M/s, then the seismic capacity,the seismic capacity of HDD is poor due to HDD high-speed operation of the internal hard disk heads.It is generally a mechanical hard drive or electrical shock if it is used in sports, it is easy to damage the hard disk.But SSD storage solutions use chip inside without heads, so it has superior seismic capacity.Even with the movement or vibration , and not easily damaged. More or less, it is the same as computer's storage, the price of SSD is much more expensive than the HDD, so a server's storage is , no matter you buy or rent , the server with SSD is more expensive than the one with HDD, but it is worth the price.At last, as a data storage system, the SSD can not recovered by the data recovery software once you delete the data. As for HDD, it can always be identified by general professional data recovery software to retrieve, perhaps this is the only disadvantage of SSD.
I believe in the future, the SSD's price will be much reduced just as the price of HDD today.

Generally speaking, yes but what is the purpose of this statement :)
