What is SSD hosting? – WAU

SSD technologies, when applied to website hosting, are related to the data storage capacity and the speed in processing information, as well as the greater credibility and performance of the page.

Do you know what SSD technology is? Consumer 4.0 yearns for personalized experiences and agility in meeting their demands. For such, became more digital: increased its reliability in online consumption and in the means of accessing technology-based goods and services.

THE online presence is increasingly important to meet this new consumption model, but the ability to present relevant content and High Availabilityfor information it is still limited to the tools and partnerships used in this process.

The SSD hosting model favors this digital strategy, as it maintains the stability of the site and the speed for accessing the information.

In this article, we will present some information pertinent to this technology, so that you can choose the most advantageous option according to your demand:

Differences between SSD and HDD technologies

SSD and HDD technologies relate to the information storage, but the way of processing, the writing capacity and the reading of data happens differently. These specificities are decisive when it comes to choose the best model.

The HDD – Hard Disk Drive, also called HD or hard disk – is a non-volatile memory, that is, the stored data is maintained even when the power supply to the system ceases. So it is a component used in notebooks, desktops and servers.

As the name hard disk indicates, its physical part, known as platter, is made up of ceramic, aluminum or glass hard drives and covered by a thin magnetic film.

In the center of the disk is an axis, so that the component rotates at high speed, and the mechanical arm at the end has a head formed by magnets nanometers away from the magnetic film, which performs the reading and recording of the data.

The SSD – Solid-State Drive or Solid State Disk, in London Solid State Disk -, is formed by integrated circuits and not disks. Since it has no moving components, it is extremely quiet and faster than HD.

In SSDs, data is stored in flash memory (also non-volatile). Because it is more compact, is the model chosen to compose smartphones and tablets.

There are some SSD drives that save data to RAM or semiconductor. Characterized by volatile memory, this should never be the architectural option for demands where it is necessary to maintain information even with the systems turned off.

The flash memory cell is made up of the controller (control gate), which communicates with the computer and where the electrical charge is applied. This tension reaches the other part, the floating gate, which stores the data and remains unchanged until a new load is activated, which means that the data can be read in the same way several times.

Advantages and disadvantages of each technology

We will describe these advantages and disadvantages both for use in IT assets, such as mobile devices and computers, and for data processing and storage infrastructures, such as servers and data centers.

The SSD is an evolution over the hard drive. Eliminating the mechanical parts of the component reduced vibrations and caused SSDs to become quieter, smaller and lighter.

In addition, recording and reading of data happens more quickly; the risk of the technology being physically damaged by shaking or falling, for example, is less – not having the reading arm like the HDD allows it not to be damaged easily, and energy consumption is more efficient.

But biggest advantage of SSD technology over HDD is speed. As the SSD data is added digitally, at any point, it does not require fragmentation and the reading of information can happen from anywhere in memory. This performance can be up to ten times higher than in an HDD without compromising energy consumption.

In contrast, SDDs still have a higher cost in the market and have less storage capacity than the hard disk, since most use MLC (Multi-Level Cell) technology, which records two bits per cell.

There are some models with greater storage capacity, such as the TLC (Triple-Level Cell), which records three bits per cell, but even so the HD in this regard becomes superior.

A problem with the flash memory that makes up the SSD (NAND Flash) is that its usefulness is limited by the number of recordings (with each new voltage, the floating gate reduces its capacity) and this does not happen with the HDD.

Despite that, with wear leveling and the TRIM feature, an SSD can last longer than the system itself where it was installed. According to Sheila Valente, technology resources analyst at Kingston, in an interview with Terra.

“A user who writes 40 GB per day, which is already a very high number and quite out of the standard if we consider everyday use, would take almost 135 years to reach the theoretical limit of rewrites. It is virtually impossible for users to exhaust this limit in regular use of SSD drives. ”

Reasons to make a website hosted on SSD

Now you will understand the reasons why SSD is more advantageous as technology for servers and data centers, especially for hosting websites. We will describe some advantages related to this application below.


As the SSD is more resistant due to the absence of small physical and mechanical parts, in the event of any type of impact, data loss is unlikely. In addition, the chances of failure are less. Therefore, the most requested files must always be saved in the SSD model, which are more secure.

File recovery also happens normally, except when information is overwritten or when formatting is not done securely.


As we said, the biggest advantage of SSD technology is speed, and this difference that characterizes the agility in data access time on websites can be a great differentiator for pages that make a large number of requests to the server and / or database.

The response time, compared to HDD hosting, can be up to twenty times longer. This is because the performance of the hard disk is conditioned by the speed of rotation of the disks. On desktops, for example, this occurs between 5,400 and 7,200 revolutions per minute (RPM).

In servers, the revolutions per minute reach 15 thousand, what makes the data to be accessed 20 milliseconds after the user’s request. In SSD, this value reduces to 0.2 milliseconds.

The SSD model can also be performed with higher performance in warmer environments (up to about 70 ° C).


This performance is related to the database, even with the demand for simultaneous processing of various information, in the hosting SSD does not occur slow common to HDD models.

This also makes the database more organized, which contributes to the performance of the rest of the system.


The life span of an HDD is long, but it may be less than that of an SSD due to its physical mechanism, which supports a limited number of revolutions and can fail after this amount is reached. Since the SSD uses flash memory, prevents the occurrence of failures that can cause permanent loss of important data.


Uptime is the time that the site is “live”, that is, the availability of information for user access. The SSD model optimizes this feature, since it has a higher data reading rate. This is a great advantage for sites with a lot of traffic.

The HDD, on the other hand, may not support a high demand for requests and result in the application falling, which considerably compromises the brand credibility, especially in the case of e-commerce.


Because it is lighter, the SSD has a reduced energy consumption, which can be very high on servers. In addition, it wears minimally, which reduces the need to replace components and, as a consequence, the cost of the hosting service. Another point that we can highlight is the lower energy consumption.

Best experience

When it comes to experience, we speak first of access speed. This interferes with the company’s credibility with its users, but also with its SEO (Search Engine Optimization) strategy, which, in turn, influences search engine results and brand visibility.

If your site takes too long to load the information, the user can give up access to the page. This behavior interferes with page ranking in search engines.

SSD hosting indication

Any website that demands a high volume of requests to the server must choose the SSD model. Some examples are:

With Digital Transformation, where users demand a high volume of information and quick access, having a better performing website is always a big advantage.

That is why SSD technology is important: not only to maintain the availability of your page, but also to earn the trust of your users and the credibility of your brand.
