What is a memory SSD, price differences with a Hard Disk Standard

Hello World,
Not everyone knows SSD (Solid State) and above all do not know the difference that can be had with any other Hard Disk.
In this article you will find all the differences in terms of price, speed, reliability, capacity and length of their life expectancy.
I hope you can be useful for general guidance on the purchase of new pieces, for any other information you can leave a comment

SSD are mass memories just like the HDD, the substantial difference is in the data storage, the SSD do it by means of a flash memory unlike the HDD that do it on a magnetic medium.

In general SSD are faster for two reasons:

• In these memories is not necessary to convert information between electronic and magnetic
• There are no mechanical parts, the data is available immediately
• In addition, SSD consume much less than the HDD, this is very important with laptops and portable because with the use of battery life will be longer.

SSD VS HDD - Speed
In general all ssd are faster.
This is because, as mentioned before, there are no mechanical parts and then storing it is much more fluid, drives SSD with DRAM are even faster
When writing make less noise and also with large files behave well, the only flaw is when we are going to write a lot of files at the same time, there is a slight drop in performance.

SSD VS HDD - Price
At the moment the ssd in the same capacity cost much more than a normal hdd
Things are changing slightly over time, but generally found cost differences also 4-5 times higher

SSD VS HDD - Reliability
It seems that both technologies are reliable.
The Hdd now have a long history behind and unlikely to break, even if they are subject to wear of time.
Unlike the SSD that do not have those long years of testing, but having no mechanical parts are not subject to wear

SSD VS HDD - Capacity
The Hdd now are very common with capacities exceeding quietly Terabytes.
The ssd instead recently have crossed the wall of 256GB coming up to 512GB, in this case, however, the prices become exorbitant, touching 300 $

SSD VS HDD - Lifetime
Both SSD HDDs that have a long life, unless you're extremely unlucky.
Hard disks are subject to wear of mechanical parts, while SSDs have a finite number of cells that can be overwritten, in any case, it is about 30 years of life for both.

SSD VS HDD - Conclusions
In general, for a user who does not care too much to write performance and that needs much space should always Hdd, robust technology with years behind and cost.
If you need a computer with access speeds well done and writing for Video Editing, Making Music, then the situation is different.
In general also the operating system becomes faster and performing on a solid-state memory.
