For decades there was a particular reliable path to keep data on a personal computer – employing a disk drive (HDD). On the other hand, this type of technology is presently expressing its age – hard disks are loud and sluggish; they are power–ravenous and are likely to create a great deal of heat for the duration of intensive procedures.
SSD drives, in contrast, are quick, consume significantly less power and are generally far less hot. They offer a new method to file access and data storage and are years ahead of HDDs when considering file read/write speed, I/O operation and then power capability. Find out how HDDs fare against the more recent SSD drives.
1. Access Time
After the launch of SSD drives, file access rates are now through the roof. Due to the new electronic interfaces employed in SSD drives, the typical data file access time has been reduced into a record low of 0.1millisecond.
HDD drives depend on rotating disks for files storage applications. Every time a file will be accessed, you have to wait around for the appropriate disk to reach the correct place for the laser to access the data file you want. This translates into an average access speed of 5 to 8 milliseconds.
2. Random I/O Performance
As a result of very same revolutionary strategy which enables for speedier access times, it’s also possible to appreciate better I/O performance with SSD drives. They will accomplish double as many functions during a given time when compared to an HDD drive.
An SSD can manage at the very least 6000 IO’s per second.
Throughout the exact same lab tests, the HDD drives demonstrated that they are considerably slower, with simply 400 IO operations maintained per second. Even though this may appear to be a large number, for those who have a hectic web server that serves a great deal of well–known websites, a sluggish hard disk drive may result in slow–loading sites.
SSD drives do not have any rotating components, meaning there’s far less machinery in them. And the fewer actually moving components you can find, the lower the possibilities of failure can be.
The regular rate of failure of an SSD drive is 0.5%.
HDD drives employ spinning hard disks for storing and reading data – a concept since the 1950s. With hard disks magnetically hanging in the air, spinning at 7200 rpm, the probability of one thing going wrong are usually increased.
The average rate of failing of HDD drives varies between 2% and 5%.
4. Energy Conservation
SSD drives are considerably small compared to HDD drives and also they don’t possess any moving elements at all. Because of this they don’t generate just as much heat and require significantly less electricity to operate and much less energy for cooling reasons.
SSDs consume amongst 2 and 5 watts.
From the time they were built, HDDs have been extremely electricity–greedy devices. When you have a hosting server with quite a few HDD drives, this will likely boost the month–to–month electric bill.
On average, HDDs take in somewhere between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ greater I/O functionality, the key web server CPU will be able to work with file calls more quickly and preserve time for additional procedures.
The average I/O wait for SSD drives is only 1%.
HDD drives enable slower accessibility speeds when compared to SSDs do, resulting for the CPU being forced to hang around, while scheduling assets for the HDD to find and return the inquired data file.
The standard I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
In real life, SSDs perform as admirably as they managed throughout HostMagia’s testing. We ran an entire system back–up using one of our own production web servers. Over the backup procedure, the common service time for I/O requests was below 20 ms.
During the very same lab tests sticking with the same hosting server, this time around fitted out using HDDs, performance was much sluggish. All through the web server backup procedure, the typical service time for I/O requests ranged between 400 and 500 ms.
7. Backup Rates
Speaking about back–ups and SSDs – we have spotted a great enhancement in the data backup rate as we moved to SSDs. Now, a typical hosting server back up takes solely 6 hours.
Over the years, we’ve got employed primarily HDD drives on our web servers and we are familiar with their functionality. On a web server built with HDD drives, a complete server backup will take about 20 to 24 hours.
