For those who have a site or an web application, speed is vital. The faster your site works and the speedier your web applications perform, the better for you. Given that a site is just a variety of files that interact with one another, the systems that store and work with these files have a crucial role in site efficiency.

Hard disk drives, or HDDs, were, until recent years, the most trusted devices for saving data. Then again, recently solid–state drives, or SSDs, have already been gathering popularity. Check out our assessment chart to find out whether HDDs or SSDs are more appropriate for you.

1. Access Time

SSD drives have a fresh & impressive solution to data storage using the use of electronic interfaces instead of any moving parts and rotating disks. This unique technology is much quicker, making it possible for a 0.1 millisecond data access time.

HDD drives still use the exact same fundamental file access technique which was initially developed in the 1950s. Even though it was much improved ever since, it’s slower when compared with what SSDs will provide. HDD drives’ data access speed ranges in between 5 and 8 milliseconds.

2. Random I/O Performance

The random I/O performance is extremely important for the performance of a file storage device. We’ve run detailed testing and have established that an SSD can manage no less than 6000 IO’s per second.

Throughout the same trials, the HDD drives proved to be considerably slower, with only 400 IO operations maintained per second. While this may seem like a significant number, for those who have an overloaded server that serves loads of well known web sites, a slow hard disk drive could lead to slow–loading web sites.

3. Reliability

SSD drives lack virtually any rotating elements, which means that there’s much less machinery included. And the fewer literally moving components you’ll find, the fewer the probability of failing are going to be.

The standard rate of failure of any SSD drive is 0.5%.

As we have already documented, HDD drives depend on rotating disks. And something that works by using lots of moving components for prolonged intervals is at risk of failure.

HDD drives’ common rate of failure ranges among 2% and 5%.

4. Energy Conservation

SSD drives operate virtually soundlessly; they don’t make surplus heat; they don’t involve added cooling down solutions and then consume a lot less power.

Trials have demostrated that the common electricity consumption of an SSD drive is somewhere between 2 and 5 watts.

From the minute they have been developed, HDDs have invariably been quite power–hungry systems. When you’ve got a server with lots of HDD drives, this will certainly increase the monthly utility bill.

Typically, HDDs consume somewhere between 6 and 15 watts.

5. CPU Power

The swifter the data access rate is, the swifter the data file calls will be handled. Because of this the CPU do not need to hold assets waiting around for the SSD to reply back.

The average I/O wait for SSD drives is only 1%.

By using an HDD, you need to invest more time awaiting the outcome of your file query. This means that the CPU will be idle for more time, looking forward to the HDD to react.

The typical I/O wait for HDD drives is approximately 7%.

6.Input/Output Request Times

In real life, SSDs perform as wonderfully as they managed during Happy Web Hosting’s testing. We produced a complete platform data backup on one of our own production servers. Over the backup process, the normal service time for any I/O demands was below 20 ms.

Weighed against SSD drives, HDDs feature significantly reduced service rates for I/O calls. In a server backup, the standard service time for an I/O query can vary between 400 and 500 ms.

7. Backup Rates

You are able to experience the real–world advantages of utilizing SSD drives each and every day. By way of example, on a web server loaded with SSD drives, a complete data backup is going to take simply 6 hours.

We worked with HDDs mainly for a few years and we have now great understanding of exactly how an HDD works. Backing up a server equipped with HDD drives is going to take around 20 to 24 hours.
