It’s a common knowledge that SSD, a.k.a. solid-state drives, are superior hard drives to HDD, hard disk drives. Therefore, servers using them are believed to be superior as well. However, is this situation really as clear-cut as it seems?
SSD Server Pros
To put it simply, SSD hard drives are indeed better than HDD in every feature you choose to compare.
- Input/Output request time for SSD is about 20ms compared to 400-500ms for HDD.
- When used with the top-notch server CPU, I/O delay for SSD drives remains within approximately 1%. To compare a CPU will have to wait a bit when you are using HDD drives. The delay is about 7%.
- Standard data access time for an SSD drive is about 0.1ms vs. 5-8ms for HDD.
You also need to keep in mind energy efficiency and reliability of solid-state hard drives. This device is designed to have the barest minimum of moving elements. This is the main difference that explains its efficiency against a drive made with a big spinning disk. Those spinning parts wear down fast no matter how careful you are. For a server, which is operating at a top performance nearly all the time, this ‘wear and tear’ rate is extremely high.
The situation with shared servers is particularly stressful for the equipment as hosting multiple websites equals an uneven workload. Therefore, one thing you can be 100% sure is that you need to get a hosting using SSD servers if you plan to use a multiple domain strategy. Check for this when comparing the services available for hosting multiple domains.
Aside from reduced ‘wear’ a device with fewer moving elements is also more energy-efficient. It doesn’t need much cooling as there isn’t constant friction that must be regulated. Therefore, SSDs are the ‘greenest’ kind of hard drive to currently exist.
Due to their high efficiency, SSD servers offer the highest level of performance that can be achieved with the current level of technology. This also means that managing the data on these drives is faster and easier.
SSD Server Cons
There’s no arguing the fact that SSD servers are superior in performance and reliability. However, you shouldn’t idolize them as this tech has two very important drawbacks.
First of all, it’s very expensive. This means that the companies using these servers must have higher rates by default. That’s not all bad as you do get more value for your money. But small businesses with limited budgets might not be able to afford them at all.
Another issue with the SSD tech is that it still has a long way to go. For all its excellent performance, it’s not 100% reliable, so there is still a risk that your website will crash. Like all new tech, SSD has its ups and downs as it’s tested by time and use. It does improve rapidly, but mishaps aren’t uncommon.
Are SSD Servers Worth the Investment?
If your business strives on data management and processing efficiency, investing in SSD will be wise. It’s a big struggle for many, but using this tech will pay off reasonably fast.
However, if having the best possible performance isn’t the main thing for you, HDD servers will be a good and definitely more affordable option.
