Most companies have switched from shared web hosting to a VPS plan,
but the smart ones dig deeper to find out the benefits of SSD as compared to
HDD VPS hosting. Which category do you belong to? Assuming you are the kind of
business person who wants to dig deep, you will want to read up on this matter
to choose the best option for your business. Presumably, that is why you are
here. Here are some differences between both to help you make an informed
decision. In addition to these factors, you also have to consider your business
requirements before choosing one option over the other.

Mechanism
HDD is an old technology that is based on the vinyl records mechanism.
This drive stores information magnetically in patterns and it has a thin disk
rotating at 7,200 revolutions per minute to read and record data. Each drive
has sensors that are capable of reading and sending the data back to the
computer’s motherboard.
The issue is that the drive disk will spin around 3.80 billion times
per year, which will result in wear and tear and eventual mechanical failure.
Conversely, SDD does not have any moving components. It stores data not in
spinning disks, but on flash memory chips.
Speed
The mechanism of working plays a big part in dictating the result of
SSD versus HDD speed tests. With moving parts in a HDD comes less write speed
and read speed than an SSD. A solid state drive can clock considerably high
read speed and write speed. The rotational latency of HDD leads to relatively
lower speeds than SSD.
Web hosting servers that use SSD will offer much better speeds
compared to the ones with HDD storage. This naturally has an effect on how the
website hosted in the SSD server runs. To cut the long story short, it will
perform better than the site hosted in an HDD server.
Data Security
Overloading of computer hardware with read/write requests can cause
hard disk failure. That failure could make your site to be offline and increase
uncertainty concerning the recovery of data. Most data centers keep a backup,
but you cannot count the possibility of losing some data because of unexpected
circumstances. The data recovery cost with HDD is greater than that of SSD.
A solid state drive comes with quicker processing time, which reduces
the possibility of failure. It also does not have mechanical parts which could
undergo wear and tear over time and cause mechanical failure. For this reason,
your data would be very secure in an SSD hosting server.
Environmental
Factors
In data centers, the use of SSD servers results in much lower consumption
of power than that of HDDs. This is since the latter drives generate heat
because of the moving components and these need more energy for cooling down.
On the contrary, an SSD does not generate such heat in the course of its
operation. In addition to having less impact on the environment, choosing an
SSD hosting option will save your financial resources too, because the plans
are relatively cheaper.
