SSDs vs HDDs
Compare the 2 industry–leading data storage space systems
At present, all new computer systems contain SSD drives instead of HDD drives. You will see superlatives on them all over the specialised press – that they’re quicker and function much better and that they are really the future of home computer and laptop manufacturing.
Having said that, how can SSDs fare in the hosting world? Are they dependable enough to replace the proved HDDs? At CV AWEBSOFT Indonesia, we are going to assist you much better understand the distinctions among an SSD and an HDD and determine the one that most accurately fits you needs.
1. Access Time
SSD drives offer a brand–new & ingenious method of file safe–keeping based on the usage of electronic interfaces as an alternative to any moving parts and turning disks. This different technology is much quicker, enabling a 0.1 millisecond data file access time.
HDD drives make use of rotating disks for data storage uses. When a file will be used, you will have to await the appropriate disk to get to the right place for the laser to view the file involved. This results in an average access speed of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is crucial for the effectiveness of a file storage device. We’ve conducted in depth trials and have identified that an SSD can handle at the very least 6000 IO’s per second.
Hard drives deliver reduced file access rates as a result of older file storage space and accessibility concept they’re employing. And in addition they show significantly reduced random I/O performance when held up against SSD drives.
For the duration of CV AWEBSOFT Indonesia’s lab tests, HDD drives dealt with around 400 IO operations per second.
3. Reliability
The absence of moving components and spinning disks inside SSD drives, as well as the recent advances in electronic interface technology have led to a substantially reliable data storage device, with a typical failing rate of 0.5%.
With an HDD drive to operate, it needs to rotate a few metallic hard disks at more than 7200 rpm, keeping them magnetically stabilized in mid–air. They have a whole lot of moving elements, motors, magnets and also other tools stuffed in a small space. Consequently it’s no surprise the common rate of failure of the HDD drive varies among 2% and 5%.
4. Energy Conservation
SSD drives are far smaller than HDD drives and also they lack just about any moving parts whatsoever. This means that they don’t generate as much heat and require less power to operate and less power for cooling purposes.
SSDs use up somewhere between 2 and 5 watts.
HDD drives are well known for getting loud; they can be liable to heating up and if there are several disk drives in a single hosting server, you have to have a different cooling system simply for them.
In general, HDDs consume somewhere between 6 and 15 watts.
5. CPU Power
Because of SSD drives’ better I/O performance, the key web server CPU can easily work with file requests much faster and preserve time for additional procedures.
The normal I/O delay for SSD drives is only 1%.
HDD drives accommodate slower access rates as opposed to SSDs do, which will result for the CPU being required to hang on, whilst reserving allocations for the HDD to uncover and give back the required file.
The regular I/O wait for HDD drives is just about 7%.
6.Input/Output Request Times
In the real world, SSDs conduct as wonderfully as they performed in the course of the testing. We ran an entire system back up using one of the production servers. During the backup operation, the common service time for I/O requests was indeed under 20 ms.
Compared to SSD drives, HDDs feature considerably slower service rates for I/O queries. In a web server backup, the standard service time for an I/O query ranges between 400 and 500 ms.
7. Backup Rates
Talking about backups and SSDs – we have detected an exceptional advancement with the data backup rate since we switched to SSDs. Currently, a normal server backup will take only 6 hours.
In the past, we’ve got employed mostly HDD drives with our web servers and we’re well aware of their performance. With a web server equipped with HDD drives, a full hosting server data backup normally takes about 20 to 24 hours.
To be able to promptly improve the efficiency of your respective sites and not have to modify any code, an SSD–driven web hosting service is a great alternative. Look at the Linux shared web hosting packages – these hosting solutions include quick SSD drives and are available at cost–effective price points.
