For many years there seemed to be a single trustworthy path to store data on a pc – having a hard drive (HDD). Nonetheless, this type of technology is presently demonstrating its age – hard disk drives are really loud and slow; they are power–ravenous and are likely to produce quite a lot of warmth throughout intense procedures.
SSD drives, alternatively, are extremely fast, take in significantly less power and tend to be much cooler. They provide a new method of file accessibility and storage and are years in advance of HDDs regarding file read/write speed, I/O operation and energy efficiency. Figure out how HDDs stand up up against the modern SSD drives.
1. Access Time
SSD drives give a completely new & impressive method to file safe–keeping using the use of electronic interfaces as an alternative to just about any moving parts and spinning disks. This new technology is considerably faster, allowing for a 0.1 millisecond file access time.
HDD drives still utilize the same fundamental data access technology that’s initially created in the 1950s. Even though it was considerably upgraded after that, it’s slow compared to what SSDs will offer. HDD drives’ file access speed varies somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Resulting from the unique radical data file storage technique embraced by SSDs, they provide speedier data access speeds and better random I/O performance.
During Capstone EasyWeb’s lab tests, all of the SSDs demonstrated their ability to deal with a minimum of 6000 IO’s per second.
Hard drives feature slower file access speeds because of the older file storage and accessibility technology they are by making use of. And in addition they display significantly slower random I/O performance compared to SSD drives.
For the duration of our lab tests, HDD drives addressed on average 400 IO operations per second.
The absence of moving parts and spinning disks in SSD drives, and the current improvements in electric interface technology have ended in a considerably reliable data storage device, having a normal failure rate of 0.5%.
With an HDD drive to work, it must rotate a few metal disks at more than 7200 rpm, keeping them magnetically stable in mid–air. They have a large amount of moving parts, motors, magnets as well as other devices stuffed in a tiny place. Consequently it’s no wonder that the average rate of failure of the HDD drive ranges between 2% and 5%.
4. Energy Conservation
SSD drives are far smaller compared to HDD drives and they lack any moving components whatsoever. Because of this they don’t create as much heat and need less energy to work and fewer power for cooling purposes.
SSDs use up somewhere between 2 and 5 watts.
From the minute they were developed, HDDs have always been very electric power–heavy equipment. So when you have a hosting server with many different HDD drives, it will boost the month to month power bill.
Typically, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
SSD drives provide for swifter data access speeds, which, subsequently, allow the CPU to complete data file queries considerably quicker and afterwards to go back to different responsibilities.
The standard I/O hold out for SSD drives is exactly 1%.
As compared with SSDs, HDDs allow for not so quick file access rates. The CPU will be required to wait for the HDD to return the inquired data, saving its assets while waiting.
The standard I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
In the real world, SSDs function as wonderfully as they have during Capstone EasyWeb’s tests. We ran an entire platform back–up using one of the production machines. Over the backup procedure, the common service time for I/O queries was in fact under 20 ms.
With the same web server, but this time loaded with HDDs, the effects were very different. The common service time for any I/O request fluctuated between 400 and 500 ms.
7. Backup Rates
You can easily notice the real–world benefits of using SSD drives every day. As an example, with a server built with SSD drives, a full backup can take merely 6 hours.
Throughout the years, we’ve got used predominantly HDD drives with our servers and we are well aware of their overall performance. With a hosting server designed with HDD drives, an entire web server data backup will take about 20 to 24 hours.
