SSD Hosting VS HDD Hosting
High Speed SSD Hosting
Probably you’ve noticed that several years ago some providers started promoting high speed SSD hosting. I hope this post will explain what is SSD hosting and if it’s really necessary for you to switch to this service.
So, as just about any computer, the web hosting server has its hard drive. It’s needed to store all the information people place in their account. In earlier times all hosting providers used HDD (Hard Disk Drives) just like all consumers did. That’s a pretty old technology that comes from the 1950s.
However, at the beginning of the 2010th, thanks to the development of technologies, consumers started choosing SSDs instead of HDDs. Why? Let’s look closer to how these two technologies work.
How SSD and HDD work
One of the main elements of HDD is a complex of numerous spinning platters. Also, HDD includes a head which stores and reads data from the spinning platters. The head is moving around its axis while the disks spin with the high speed. As you can see, this involves some mechanical actions and this means pretty high response time.
SSD (Solid State Drive) uses microchips and is very similar to memory cards you use in your photo camera or a smartphone. It lacks mechanical parts and data is transmitted by means of electrical signals. The lack of mechanical parts not only allows using SSD in devices which may suffer shakes and drops but also improves response time greatly. They just don’t have the delay for mechanical stuff.
SSD VS HDD Speed
While benefits of SSD may be obvious after this explanation, it’s not that simple when it comes to SSD VS hard drive in hosting industry.
The truth is HDDs are much (2-3 times) cheaper for a hosting company. Thus you may notice that to keep the competitive pricing, hosting providers offer less disk space for plans with SSDs while other features may be just about the same. This means that if a lot of disk space is a must for you then most likely you should go for HDD hosting. Usually, this is true for file storages, image galleries and so on.
But let’s get back to the speed. SSD really provides much higher speed for reading/writing from/to drive. Also, file transfer speed is much higher which is very useful if you conduct a lot of such operations with your hosting plan.
However, you should always remember that the high speed of SSD is not the only parameter which influences your website speed. There are such things as website optimization, connection speed, CPU and RAM, web server configuration and so on. If any other of these things is a bottleneck then SSD won’t help you.
Also, you need to figure out a very important limit of your hosting service provider – Input/Output. It’s measured in MB per second and if it’s low then it’s possible that the advantage of having SSD storage would be lost. Try to get a hosting with at least 3 MB/s.
SSD or HDD
If you’re looking for a VPS or a dedicated server then you have to know that SSD option also exists for such services. However, if you’re going to get SSD VPS then you will have less disc space than you’d get with HDD server.
So, if your site is optimized and the speed is crucial for you then it’s strongly recommended to take advantage of the money back guarantee in order to check if this or that hosting provider will suit your needs. You can test SSD vs HDD performance of your website and make a final decision.
