SSDs vs HDDs
Review the two industry–leading data storage systems
These days, virtually all new computer systems are equipped with SSD drives instead of HDD drives. You can find superlatives about them all over the specialised press – that they’re a lot faster and conduct far better and they are actually the future of home pc and laptop generation.
Nonetheless, how do SSDs fare in the website hosting community? Are they responsible enough to replace the successful HDDs? At konceptHOSTING, we’ll help you far better see the dissimilarities in between an SSD and an HDD and choose the one that most accurately fits you needs.
1. Access Time
With the introduction of SSD drives, data access rates are now over the top. With thanks to the new electronic interfaces utilised in SSD drives, the common data file access time has shrunk towards a all–time low of 0.1millisecond.
HDD drives count on rotating disks for data storage reasons. Every time a file will be utilized, you need to wait around for the correct disk to reach the right position for the laser to reach the file in question. This results in an average access speed of 5 to 8 milliseconds.
2. Random I/O Performance
On account of the very same radical strategy enabling for better access times, you can also experience better I/O performance with SSD drives. They can perform twice as many procedures within a given time in comparison to an HDD drive.
An SSD can deal with at least 6000 IO’s per second.
With an HDD drive, the I/O performance progressively raises the more you apply the disk drive. Having said that, right after it reaches a specific limitation, it can’t get speedier. And due to the now–old technology, that I/O restriction is much less than what you can get with a SSD.
HDD are only able to go as much as 400 IO’s per second.
3. Reliability
The lack of moving components and rotating disks inside SSD drives, as well as the current improvements in electrical interface technology have resulted in a much reliable data file storage device, having a typical failure rate of 0.5%.
With an HDD drive to work, it should spin 2 metal hard disks at a minimum of 7200 rpm, keeping them magnetically stabilized in the air. There is a good deal of moving parts, motors, magnets and other gadgets loaded in a tiny location. Hence it’s no surprise the normal rate of failing associated with an HDD drive ranges in between 2% and 5%.
4. Energy Conservation
SSDs are lacking moving components and need little or no chilling power. In addition they need a small amount of power to operate – lab tests have shown that they can be powered by a regular AA battery.
In general, SSDs consume somewhere between 2 and 5 watts.
From the minute they were made, HDDs were always really energy–hungry products. When you have a server with lots of HDD drives, this will certainly add to the month–to–month electricity bill.
Normally, HDDs take in somewhere between 6 and 15 watts.
5. CPU Power
The speedier the data file access rate is, the faster the data queries are going to be adressed. As a result the CPU won’t have to reserve resources looking forward to the SSD to answer back.
The common I/O wait for SSD drives is simply 1%.
If you use an HDD, you will need to dedicate extra time waiting around for the outcome of one’s file query. Because of this the CPU will stay idle for more time, looking forward to the HDD to respond.
The common I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
It’s time for some real–world instances. We competed a complete system backup on a hosting server only using SSDs for file storage purposes. In that process, the normal service time for any I/O demand remained beneath 20 ms.
With the same hosting server, but this time furnished with HDDs, the outcome were completely different. The common service time for an I/O call changed between 400 and 500 ms.
7. Backup Rates
Yet another real–life advancement is the speed at which the data backup is developed. With SSDs, a hosting server back up now can take less than 6 hours by using konceptHOSTING’s web server–optimized software.
On the other hand, on a server with HDD drives, the same back–up could take three or four times as long in order to complete. A full back up of any HDD–powered server often takes 20 to 24 hours.
