For decades there was a single reliable path to store data on a personal computer – with a hard disk drive (HDD). Nevertheless, this sort of technology is presently demonstrating its age – hard disks are actually loud and slow; they can be power–ravenous and have a tendency to create quite a lot of warmth throughout intense operations.

SSD drives, on the other hand, are extremely fast, consume much less energy and are much cooler. They provide an exciting new approach to file access and storage and are years in advance of HDDs in relation to file read/write speed, I/O performance and power efficiency. Observe how HDDs fare against the newer SSD drives.

1. Access Time

Image

After the launch of SSD drives, file access rates are now through the roof. On account of the completely new electronic interfaces utilised in SSD drives, the typical data file access time has been reduced to a all–time low of 0.1millisecond.

Image

HDD drives even now makes use of the very same general file access technique that was initially created in the 1950s. Though it was vastly improved since then, it’s slow when compared to what SSDs will provide. HDD drives’ data file access rate can vary somewhere between 5 and 8 milliseconds.

2. Random I/O Performance

Image

Due to the new radical data storage method shared by SSDs, they have quicker file access speeds and speedier random I/O performance.

Throughout Asora Host’s lab tests, all SSDs demonstrated their ability to handle at the least 6000 IO’s per second.

Image

Throughout the same tests, the HDD drives demonstrated to be considerably slower, with simply 400 IO operations handled per second. Even though this may appear to be a good deal, when you have a hectic server that serves a lot of well–known sites, a slow harddrive can result in slow–loading sites.

3. Reliability

Image

The lack of moving parts and rotating disks in SSD drives, and also the latest improvements in electronic interface technology have generated a substantially safer data file storage device, with an common failing rate of 0.5%.

Image

With an HDD drive to work, it should spin a couple metallic hard disks at over 7200 rpm, retaining them magnetically stable in mid–air. They have a massive amount moving parts, motors, magnets and also other gadgets packed in a small place. Therefore it’s no wonder that the common rate of failure of any HDD drive varies between 2% and 5%.

4. Energy Conservation

Image

SSD drives are considerably smaller than HDD drives as well as they lack just about any moving elements whatsoever. Because of this they don’t make just as much heat and require a lot less electricity to work and much less power for chilling purposes.

SSDs consume between 2 and 5 watts.

HDD drives can be infamous for getting loud; they are at risk from overheating and in case you have several hard drives in one hosting server, you must have an extra cooling device only for them.

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

5. CPU Power

Image

The faster the data access rate is, the swifter the data requests can be processed. As a result the CPU do not need to save resources looking forward to the SSD to answer back.

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

Image

In comparison to SSDs, HDDs permit slower data access speeds. The CPU will have to lose time waiting for the HDD to return the required data file, saving its resources for the time being.

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

6.Input/Output Request Times

Image

Almost all of our brand–new machines moved to just SSD drives. Our personal tests have demostrated that utilizing an SSD, the normal service time for any I/O request whilst running a backup continues to be below 20 ms.

Image

All through the very same trials using the same server, this time equipped out utilizing HDDs, efficiency was considerably sluggish. All through the web server back–up procedure, the normal service time for I/O demands ranged somewhere between 400 and 500 ms.

7. Backup Rates

Image

Another real–life advancement is the speed with which the backup is created. With SSDs, a server data backup now will take no more than 6 hours using Asora Host’s server–optimized software solutions.

Image

In contrast, on a hosting server with HDD drives, the same back–up usually takes 3 to 4 times as long in order to complete. An entire backup of any HDD–driven web server typically takes 20 to 24 hours.
