SSD Hosting Vs HDD Hosting

SSD Hosting Vs HDD Hosting

As we all know the websites we use are retrieved from the servers on our requests. When we type the site URL in our web-browser, these data are brought to us from servers located in different parts of the world. So to make this process faster and efficient our hosting provider needs save these websites in storage drives having faster data access or data read/write mechanisms on their servers.

To achieve this, the hosting providers use the following storage techniques :

Solid State Drive [SDD] Hosting which uses Solid State Drives to store website data,
Hard Disk Drive [HDD] Hosting which uses Hard Disk Drives to store website data.

Storing the website in Hard Disk Drive is a traditional way of storing , while using Solid State Drive is the latest and advanced way of storing websites. Both SDD and HDD have their own advantages and disadvantages.

Let’s have a look into the traditional way of storing website data in HDDs – HDDs use Electromagnetic effect to store and retrieve data on a rotating platter. The data are retrieved/read using an actuator arm or head, each magnetic disk has its own head for data retrieval. The head floats above the spinning platter reading and writing data. The faster the platter spins faster the HDD can perform. A slider is used to move the head from outside of the platter to inside. At a particular instant the head can only be in one place, and it takes time to move the head from one position to another. It takes a few milliseconds to move the head even 1mm away to access the data, hence there is a delay in response.

Coming into the case of SSDs, it is a flash storage device and do not contain any moving parts. Here the information is stored in microchips. For better understanding SDDs can be thought of as an oversized and more sophisticated version of a USB memory stick. The SSD uses NAND-based flash memory which is a non-volatile type of memory. To read and write data, SSD consists of an embedded controller, based on the speed of this controller, which makes the decision of how to store, cache, retrieve and clean up data determine the overall speed of the drive.

Key aspects of SSD Web hosting and HDD Web hosting


The current trend in website development has changed to open source web applications such as Joomla, Drupal and WordPress, as they provide auser-friendly interface for users to create a website, and the flexibility to customize the website you have created, The problem is, these web applications are being dynamic, which triggers database queries and content accessible at the same time, which need server with really fast access time or response time.

Also in the case of e-Commerce websites, the loading speed of the website acts as the key-factor. A slow website makes the customers frustrated, which forces the customer to leave the cart or the website itself.

According to the survey of KISSmetrics data, even if you think 4 seconds to load the billing page of your website is a reasonable time, the survey results says that you have lost 25 percent of your potential customers.

When a user access your website or opens a page in your website, in the case of data stored in HDD server, it takes time to spin to locate the information for your website which leads to a delay of few [15-20] milliseconds. This delay does not matter in case of websites having low loads or if traffic to that site is less, but this delay will get longer in case of websites with heavy load of activities with a large number of users accessing it.

But for SDD there are no moving parts, ie there is no mechanical movement every time the data is accessed, So in the case of response time SDDs are as much as 100 times faster than HDD. Hence this leads to :

Input/Output speed to and from the server is increased,
Immediate access to stored data of your website,
Reduced loading time for your websites,
High conversion rate,
Greater throughout.

Hence Web hosting in SDD is more than 300% faster than traditional HDD web hosting in the aspect of response time.


The main concern of using HDD is data loss, because the chances of physical damage are very high as it contains moving parts. Since they have sensitive mechanical parts, any slight mishandling can cause irreversible damage to your data.

Also in HDD the moving parts cause friction which leads to heat generation, heat beyond a limit, may also cause damage to the data stored on the HDD. Effects of electromagnetism increase the chances of erasing the stored data and also shortens the life of other components of the HDD.

In the case of SSD everything is integrated into a microchip which is controlled by an embedded controller, which perform a bunch of operation related to reading and writing of data. So SSD is immune to damage caused to the stored data due to physical movements.

Stability and Security

As mentioned above , SSDs have no moving parts, so there is less chance to skip during data encryption and decryption process, which makes SSDs stable compared to HDDs.

In the aspect security in SSD data is encrypted with SafeGuard Device Encryption, which allows to encrypt the data sector by sector.

In HDD data is fragmented and stored, if you are storing an amount of data of a single site which is fragmented, while accessing this fragmented content may cause delay and even skipping content while accessing it.

While in SSD data is not stored as fragmented, rather the data is stored more systematically and orderly manner so that less time is spent to find and access the data compared to HDD.

Since the data is stored in flash memory in SSDs, they are non-volatile, your data remains persistent.

SSDs support batch operations, which speeds up the access to the flash memory.

Power Consumption

Power consumption in HDD is high compared to SDD as it needs more power to move the mechanical parts like the actuator arm, slider and to rotate the platter. SSDs used in cloud storage consume around 80% less power on a per gigabyte basis compared to HDDs. It is a sizable amount of energy saving at the scale of entire data centres.


In the aspect of scalability SSD is not scalable as HDD.


In case of price SSDs are about 7 to 8 times more expensive than per unit of storage than HDDs,
The HDD is capable of storing huge amount of data cheaply.

If you are willing to pay for faster performance and can work around limited storage capacity, the SSD hosting is the right choice.

The HDD hosting might be your right choice if you need lots of storage capacity, or you need to host your website at the least price possible and if performance of your website is your secondary preference.
