When you have a website or an web application, pace is really important. The faster your site loads and the faster your apps function, the better for you. Since a website is an array of files that connect with one another, the devices that keep and work with these data files play a vital role in site operation.

Hard disk drives, or HDDs, have been, until the past few years, the most reliable devices for keeping information. Nonetheless, in recent times solid–state drives, or SSDs, are actually becoming more popular. Have a look at our comparability chart to view whether HDDs or SSDs are more appropriate for you.

1. Access Time

With the launch of SSD drives, file access speeds are now over the top. Thanks to the brand–new electronic interfaces found in SSD drives, the average file access time has shrunk to a record low of 0.1millisecond.

HDD drives count on rotating disks for files storage purposes. Every time a file is being used, you will have to await the correct disk to reach the right position for the laser to access the file involved. This leads to an average access rate of 5 to 8 milliseconds.

2. Random I/O Performance

With thanks to the very same radical approach that allows for quicker access times, you can also experience better I/O effectiveness with SSD drives. They’re able to conduct double as many procedures during a specific time as compared with an HDD drive.

An SSD can manage a minimum of 6000 IO’s per second.

With an HDD drive, the I/O performance gradually enhances the more you use the hard drive. Nonetheless, once it gets to a specific cap, it can’t go faster. And due to the now–old concept, that I/O limitation is noticeably lower than what you can receive with an SSD.

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

3. Reliability

SSD drives are created to have as less moving parts as possible. They use an identical concept to the one employed in flash drives and are more efficient as compared to common HDD drives.

SSDs have an typical failing rate of 0.5%.

For an HDD drive to function, it has to spin a pair of metallic disks at over 7200 rpm, holding them magnetically stable in mid–air. There is a lot of moving parts, motors, magnets along with other tools crammed in a tiny place. Therefore it’s no surprise the normal rate of failure of an HDD drive can vary somewhere between 2% and 5%.

4. Energy Conservation

SSD drives operate practically silently; they don’t generate surplus warmth; they don’t mandate added cooling solutions and use up considerably less energy.

Tests have demostrated that the typical electricity use of an SSD drive is somewhere between 2 and 5 watts.

HDD drives are infamous for getting loud; they’re at risk of getting too hot and in case there are several disk drives within a hosting server, you must have a different a / c system simply for them.

All together, HDDs use up in between 6 and 15 watts.

5. CPU Power

The speedier the data file accessibility rate is, the faster the data file demands can be delt with. Consequently the CPU will not have to arrange allocations looking forward to the SSD to reply back.

The standard I/O delay for SSD drives is actually 1%.

HDD drives allow for reduced access rates than SSDs do, which will result for the CPU required to delay, whilst arranging assets for the HDD to locate and return the inquired data file.

The regular I/O wait for HDD drives is just about 7%.

6.Input/Output Request Times

In real life, SSDs conduct as wonderfully as they did throughout Space Hammer Hosting’s testing. We produced a full platform backup using one of the production servers. Over the backup operation, the average service time for I/O requests was in fact below 20 ms.

In contrast to SSD drives, HDDs provide noticeably slower service rates for I/O queries. During a web server backup, the standard service time for an I/O query can vary between 400 and 500 ms.

7. Backup Rates

Discussing back ups and SSDs – we have spotted a significant development in the data backup rate as we turned to SSDs. Currently, a regular web server backup takes just 6 hours.

We implemented HDDs mainly for several years and we’ve decent familiarity with just how an HDD runs. Backing up a server equipped with HDD drives will take about 20 to 24 hours.

The Linux cloud website hosting packages accounts include SSD drives by default. Be part of our family here, at Space Hammer Hosting, and discover how we can help you enhance your site.
