The web hosting landscape has witnessed some technological marvels over the last decade or so. With virtualization opening new avenues for hosting services, the storage solutions have also undergone a massive upgrade. Traditionally, hard disk drives or HDDs were synonymous with storage. These drives had physical moving parts and the disk rotated every time it needed to locate data. As the speed and performance of the server started gaining importance, technology experts realized that the HDDs were slowing down the website due to the way they were designed. Hence, servers needed a more efficient storage option. Eventually, when solid-state drives or SSDs were invented, they didn’t have most of the disadvantages of HDDs. Hence, the performance was better and Web Hosting received a much needed shot in the arm. All hosting types – Shared Hosting, VPS, Dedicated Servers, Cloud Hosting, etc., started leveraging the benefits of SSDs and offered SSD-based hosting services to websites. Today, we are going to help you understand why you should opt for an SSD-based plan if you are considering migrating to Cloud Hosting.
Better Site Speed & Performance
Here are some simple facts:
- With HDDs, the read/write speeds are up to 200 MB/s
- With SSDs, the read/write speeds are from 200-2500 MB/s
- With HDDs, the time taken to access a memory address is between 5.5 and 8 ms
- With SSDs, the time taken to access a memory address is around 0.1 ms
This difference is primarily due to the lack of any moving parts in an SSD. While these differences might not seem huge (considering a difference of a few milliseconds), they can make a significant impact on the performance of a website. This is especially useful for sites experiencing heavy traffic (like e-commerce platforms) or those sites that need high speed and performance.
- Better Durability & Reliability
HDDs store data in the form of small magnetic fields on a platter that is read by a moving head. On the other hand, SSDs use microchips to store data. This makes them more durable than HDDs. Also, HDDs have a failure rate between 2 and 5 percent while SSDs have a failure rate of less than 0.5 percent, making them 4-10 times more reliable than HDDs.
- Lower consumption of Power
The I/O wait is the time that the CPU lies idle waiting for an I/O operation to complete. It is usually denoted as the percentage of time that a CPU had an outstanding input/output task. With HDDs, the average I/O wait time is about 7% while with SSDs it is 1%. Also, on average, HDDs consume between 6 and 15 watts of power while SSDs consume between 2 and 5 watts. These factors make SSDs more power-efficient than HDDs.
- Faster Backups
Typically, SSDs help you backup your data 3-5 times faster than the traditional HDDs. If an HDD takes around 24 hours to back up a certain amount of data, an SSD can complete the process in merely 6 hours.
As you can see, SSDs offer a lot of benefits to websites. Combined with the wide range of advantages of Cloud Hosting, websites have a near-perfect hosting service. While SSDs are costlier than HDDs, they offer value for money by ensuring optimum site performance. Hence, if you are planning to migrate to a Cloud-based Hosting service, then you might want to consider a plan that uses SSDs instead of HDDs.
