For those who have a site as well as an application, rate of operation is very important. The faster your web site loads and the swifter your apps function, the better for you. Considering that a web site is only a set of data files that communicate with each other, the devices that keep and work with these data files play a vital role in web site general performance.

Hard disk drives, or HDDs, were, until the past few years, the most efficient systems for keeping information. Nonetheless, in recent times solid–state drives, or SSDs, are actually gathering popularity. Look into our evaluation chart to find out whether HDDs or SSDs are more suitable for you.

1. Access Time

After the release of SSD drives, file accessibility rates are now over the top. With thanks to the brand new electronic interfaces utilized in SSD drives, the typical file access time has shrunk to a record low of 0.1millisecond.

The concept behind HDD drives times all the way back to 1954. And while it’s been substantially processed throughout the years, it’s nonetheless can’t stand up to the ground breaking concept driving SSD drives. Using today’s HDD drives, the best file access speed you can achieve can vary somewhere between 5 and 8 milliseconds.

2. Random I/O Performance

The random I/O performance is extremely important for the operation of any file storage device. We have carried out in depth exams and have identified an SSD can handle no less than 6000 IO’s per second.

With an HDD drive, the I/O performance steadily improves the more you use the hard drive. Nevertheless, right after it reaches a certain restriction, it can’t proceed swifter. And due to the now–old technology, that I/O limit is much below what you can have having an SSD.

HDD are only able to go as far as 400 IO’s per second.

3. Reliability

The absence of moving parts and rotating disks within SSD drives, as well as the recent improvements in electrical interface technology have generated a substantially better data file storage device, with an normal failure rate of 0.5%.

As we already have mentioned, HDD drives rely upon rotating disks. And something that utilizes many moving parts for lengthy periods of time is liable to failing.

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

4. Energy Conservation

SSDs lack moving elements and require almost no cooling down energy. In addition they need not much energy to function – lab tests have revealed that they can be operated by a standard AA battery.

As a whole, SSDs take in between 2 and 5 watts.

HDD drives are well known for getting loud; they’re more likely to overheating and whenever there are several disk drives in one server, you’ll want an additional air conditioning device only for them.

All together, HDDs consume between 6 and 15 watts.

5. CPU Power

As a result of SSD drives’ greater I/O performance, the main web server CPU will be able to work with file calls faster and save time for additional procedures.

The regular I/O delay for SSD drives is just 1%.

HDD drives accommodate reduced accessibility rates compared with SSDs do, which will result in the CPU being forced to wait around, although scheduling resources for the HDD to locate and return the requested data file.

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

6.Input/Output Request Times

In the real world, SSDs carry out as perfectly as they did for the duration of’s lab tests. We produced an entire system data backup on one of our production machines. During the backup procedure, the average service time for I/O calls was basically below 20 ms.

Compared with SSD drives, HDDs offer noticeably slower service times for I/O calls. Throughout a hosting server backup, the regular service time for any I/O call varies between 400 and 500 ms.

7. Backup Rates

You’ll be able to experience the real–world benefits of using SSD drives each and every day. By way of example, on a server built with SSD drives, a complete back–up will take merely 6 hours.

Alternatively, on a hosting server with HDD drives, an identical back up takes 3 to 4 times as long to finish. An entire back up of any HDD–equipped server normally takes 20 to 24 hours.
