There are various technologies involved in hosting a website, most of which are unknown to its users. In creating for excellent website performance, every aspect matters. After all, the utilization of the net grows, along with the expectation of the people. Who increasingly expect fast and efficient navigation. We’re talking about SSD drives.
Among the technologies involved, one in all of them concerns the storage of data. Traditionally, the servers utilize hard drives for this – the famous HD, equally present in personal computers. But a couple of years ago a new technology came on the scene and is changing for the better not only our computers but also servers, being present more and more in large data centres.
In this article, we’ll determine what SSD is, its features and therefore, the benefits that this storage technology can bring to your hosting.

What is SSD
The acronym for SSD is Solid State Drive. Also referred to as a flash disk, this device gets used to store data permanently, and we can get on both personal computers and servers.
The SSDs represent an improvement compared to the standard hard drive, or HDD (Hard Disk Drive). Both devices are to store data permanently; that’s so that the data gets preserved, although the pc is turned off and disconnected from the power supply.
But then, what’s the makes SSD different from an HDD? It’s necessary to know the characteristics of each of them to get a solution, as we are going to see next.

Features of HDDs
An HDD (Hard Disk Drive), also referred to as HD or just hard drive, has one or more rotating disks and a mechanical arm. The discs are made from metal and have a magnetic layer, thus allowing the recording of the info. At the tip of it, there’s an electromagnetic sensor, responsible for reading and writing the info on this disk. So as for information to be recorded or retrieved, the disc must rotate. And the player has to be in the position in the exact location where the data is/will get recorded.
The read/write time of the data in a traditional HD will be determined mainly by the speed of the disk rotation. On personal computers, it’s common to find HDs from 5400 to 7200 RPM (rotations per minute). On servers, disks up to 15,000 RPM are typical.
In addition to the problem of spin speed, the issue of information fragmentation also must be considered. In traditional HDD, data gets recorded on a specific area of the magnetic disk, called sectors. Due to this architecture, one file gets stored in parts scattered throughout the hard drive, physically distant from each other. It results in a fair slower reading of the info. To resolve this problem, you need to “defragment” the info from time to time. Modern operating systems try this regularly, without the user having to start the procedure. Still, this can be an issue when the disk is just too full, close to its full capacity.
Features of SSDs
A solid-state disk (SSD) does not have any moving parts, and all information is recorded and accessed in an electronic circuit. Its architecture is sort of like a to it of a pen drive. However, the speed of access to information is more significant than that found on this device. Recording and accessing data is quicker on the SSD, and there’s no problem with having fragmented files in your memory because the access speed is the same anywhere on the device.
To get an idea of its performance, the info access speed on an SSD is 0.2 milliseconds, while it can reach 20 milliseconds on an HDD*. This difference could seem small since we are talking about milliseconds. But when it involves accessing and storing a large amount of data, the performance gain can be significant.
SSD was invented decades after the HDD, and only about ten years ago computer manufacturers began to use it on a vast scale. The price has always been a decisive issue for those that need to choose one of these technologies. Generally, the cost of an SSD is more than that of an HDD. But fortunately, with the evolution of technology, this difference has been reduced to way more affordable levels.
