For decades there was a single trustworthy solution to keep data on your computer – employing a disk drive (HDD). Having said that, this type of technology is currently expressing it’s age – hard disks are really noisy and slow; they can be power–ravenous and tend to produce a great deal of warmth during intensive procedures.
SSD drives, alternatively, are fast, consume way less power and are generally much cooler. They feature a completely new solution to file access and data storage and are years in front of HDDs relating to file read/write speed, I/O effectiveness as well as energy efficacy. See how HDDs stand up up against the modern SSD drives.
1. Access Time
SSD drives present a brand–new & innovative approach to data storage based on the usage of electronic interfaces rather than any moving parts and rotating disks. This brand new technology is considerably faster, enabling a 0.1 millisecond file access time.
The concept driving HDD drives dates all the way back to 1954. And even though it’s been considerably enhanced progressively, it’s nevertheless can’t stand up to the innovative technology powering SSD drives. Utilizing today’s HDD drives, the very best file access rate you can achieve varies somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Thanks to the same revolutionary approach enabling for better access times, also you can take pleasure in better I/O performance with SSD drives. They can perform double as many procedures during a given time as compared with an HDD drive.
An SSD can deal with at the least 6000 IO’s per second.
Hard drives offer slower file access rates because of the aging file storage and accessibility technology they’re employing. Additionally they display much sluggish random I/O performance in comparison with SSD drives.
For the duration of our tests, HDD drives dealt with an average of 400 IO operations per second.
The absence of moving parts and spinning disks in SSD drives, as well as the recent improvements in electric interface technology have led to an extremely reliable file storage device, having an common failing rate of 0.5%.
Since we have previously observed, HDD drives depend on rotating hard disks. And something that works by using a lot of moving elements for continuous time frames is at risk from failing.
HDD drives’ average rate of failure varies between 2% and 5%.
4. Energy Conservation
SSDs do not have moving elements and require little or no cooling energy. Additionally, they call for very little energy to operate – trials have shown that they can be operated by a regular AA battery.
As a whole, SSDs take in somewhere between 2 and 5 watts.
HDD drives are notorious for being noisy; they’re at risk of getting hot and if you have several hard drives in one web server, you will need an extra cooling system used only for them.
As a whole, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
As a result of SSD drives’ better I/O functionality, the key server CPU will be able to process data requests faster and preserve time for other procedures.
The regular I/O wait for SSD drives is just 1%.
HDD drives allow for slower access rates in comparison to SSDs do, resulting for the CPU being forced to hang on, although arranging allocations for the HDD to find and give back the requested file.
The normal I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
In real life, SSDs perform as wonderfully as they did throughout Pagesroot’s checks. We ran an entire platform back up on one of our production servers. Over the backup operation, the typical service time for I/O queries was indeed under 20 ms.
Weighed against SSD drives, HDDs offer considerably slower service rates for input/output queries. During a server backup, the regular service time for an I/O query ranges somewhere between 400 and 500 ms.
7. Backup Rates
A different real–life development is the speed at which the backup was made. With SSDs, a hosting server back up today will take less than 6 hours implementing Pagesroot’s web server–optimized software solutions.
Through the years, we’ve utilized primarily HDD drives on our web servers and we’re well aware of their performance. On a server pre–loaded with HDD drives, a full hosting server back–up may take about 20 to 24 hours.
Should you want to immediately improve the efficiency of your websites and not having to modify any code, an SSD–equipped website hosting service is really a really good option.
