Once you have a website or perhaps an web app, pace is essential. The quicker your web site functions and the quicker your applications function, the better for everyone. Because a site is only a group of files that interact with each other, the devices that store and access these data files play a huge role in web site operation.
Hard disk drives, or HDDs, have been, until recent years, the most trustworthy products for storing data. However, lately solid–state drives, or SSDs, have already been gathering popularity. Check out our comparison chart to find out whether HDDs or SSDs are better for you.
1. Access Time
Resulting from a revolutionary new method to disk drive functionality, SSD drives make it possible for faster data file access speeds. Having an SSD, file accessibility times are much lower (just 0.1 millisecond).
HDD drives continue to utilize the very same basic file access technology which was initially developed in the 1950s. Though it was substantially enhanced consequently, it’s slow in comparison to what SSDs are offering. HDD drives’ data access rate can vary somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is vital for the performance of a file storage device. We have run thorough tests and have established that an SSD can manage no less than 6000 IO’s per second.
Throughout the exact same trials, the HDD drives demonstrated that they are significantly slower, with 400 IO operations maintained per second. Although this may seem like a good deal, for people with a hectic server that contains a lot of sought after websites, a slow hard drive can lead to slow–loading sites.
The lack of moving elements and rotating disks inside SSD drives, and also the current advancements in electronic interface technology have ended in a much less risky file storage device, with an average failure rate of 0.5%.
HDD drives make use of rotating disks for saving and reading through data – a technology dating back to the 1950s. Along with hard disks magnetically hanging in the air, spinning at 7200 rpm, the likelihood of one thing going wrong are considerably increased.
The common rate of failing of HDD drives varies between 2% and 5%.
4. Energy Conservation
SSDs do not have moving elements and need not much cooling down power. Additionally, they require a small amount of power to perform – tests have demonstrated they can be powered by a standard AA battery.
As a whole, SSDs use up somewhere between 2 and 5 watts.
From the time they were created, HDDs have invariably been quite electric power–greedy systems. And when you’ve got a web server with many types of HDD drives, it will raise the monthly electric bill.
On average, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ greater I/O efficiency, the key server CPU can easily work with data file queries a lot quicker and save time for additional procedures.
The normal I/O wait for SSD drives is 1%.
When you use an HDD, you will need to devote extra time awaiting the results of your file call. Consequently the CPU will continue to be idle for extra time, awaiting the HDD to react.
The average I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
In the real world, SSDs conduct as perfectly as they performed for the duration of the checks. We ran a full platform back–up using one of our own production machines. All through the backup process, the standard service time for any I/O queries was indeed under 20 ms.
Compared with SSD drives, HDDs deliver noticeably slower service rates for I/O queries. During a hosting server backup, the common service time for an I/O call can vary somewhere between 400 and 500 ms.
7. Backup Rates
Yet another real–life enhancement will be the speed at which the back–up has been developed. With SSDs, a hosting server backup today will take only 6 hours implementing Jr.ConeyHost’s server–optimized software solutions.
We applied HDDs exclusively for a few years and we have now very good familiarity with precisely how an HDD works. Generating a backup for a hosting server furnished with HDD drives will take around 20 to 24 hours.
