For decades there seemed to be only one trustworthy way to keep info on a pc – employing a hard disk drive (HDD). However, this kind of technology is already demonstrating its age – hard drives are actually loud and slow; they are power–ravenous and tend to generate a lot of heat during intensive operations.

SSD drives, on the contrary, are really fast, consume way less power and are also far less hot. They provide a whole new method of file access and storage and are years ahead of HDDs in terms of file read/write speed, I/O effectiveness as well as power efficiency. Find out how HDDs stand up against the more recent SSD drives.

1. Access Time

Image

A result of a radical new approach to disk drive performance, SSD drives permit for much faster data accessibility speeds. With an SSD, data accessibility instances are far lower (as small as 0.1 millisecond).

Image

The technology driving HDD drives goes back to 1954. Even though it has been significantly processed throughout the years, it’s nevertheless no match for the ingenious ideas driving SSD drives. Having today’s HDD drives, the top data access rate you’ll be able to reach can vary between 5 and 8 milliseconds.

2. Random I/O Performance

Image

On account of the new significant data file storage approach embraced by SSDs, they supply quicker file access rates and faster random I/O performance.

During BitLife Host’s trials, all SSDs confirmed their capacity to handle no less than 6000 IO’s per second.

Image

During the same tests, the HDD drives demonstrated that they are much slower, with 400 IO operations handled per second. Although this may appear to be a good deal, for people with a busy server that contains a great deal of well–known websites, a slow hard disk could lead to slow–loading web sites.

3. Reliability

Image

The absence of moving components and rotating disks in SSD drives, and the latest developments in electric interface technology have resulted in a significantly risk–free file storage device, with a normal failing rate of 0.5%.

Image

For the HDD drive to function, it should spin a pair of metal hard disks at more than 7200 rpm, retaining them magnetically stable in mid–air. They have a whole lot of moving elements, motors, magnets along with other gadgets jammed in a small space. Hence it’s no wonder that the standard rate of failure of an HDD drive ranges somewhere between 2% and 5%.

4. Energy Conservation

Image

SSDs lack moving elements and need almost no chilling energy. Additionally, they demand not much energy to operate – trials have demonstrated that they’ll be operated by a regular AA battery.

As a whole, SSDs consume between 2 and 5 watts.

Image

HDD drives are renowned for becoming loud. They want extra electrical power for chilling reasons. With a web server which has different HDDs running regularly, you will need a great deal of fans to make sure they’re kept cool – this will make them much less energy–effective than SSD drives.

HDDs take in somewhere between 6 and 15 watts.

5. CPU Power

Image

Thanks to SSD drives’ greater I/O effectiveness, the key hosting server CPU will be able to process data file queries a lot quicker and save time for other operations.

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

Image

If you use an HDD, you will need to spend more time watching for the results of your data file request. This means that the CPU will be idle for extra time, awaiting the HDD to reply.

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

6.Input/Output Request Times

Image

In the real world, SSDs conduct as perfectly as they managed throughout the checks. We produced a full platform back–up on one of the production web servers. Through the backup process, the normal service time for I/O requests was in fact under 20 ms.

Image

With the same server, however, this time furnished with HDDs, the results were totally different. The regular service time for any I/O request changed in between 400 and 500 ms.

7. Backup Rates

Image

You’ll be able to experience the real–world benefits to utilizing SSD drives on a daily basis. For example, on a hosting server with SSD drives, a full back–up will take merely 6 hours.

Image

We utilized HDDs mainly for lots of years and we’ve decent comprehension of just how an HDD functions. Generating a backup for a web server equipped with HDD drives will take around 20 to 24 hours.
