SSDs vs HDDs
Compare and contrast the two industry–leading data storage systems
Once you have a web site or an application, speed is extremely important. The quicker your site loads and also the swifter your web apps perform, the better for you. Given that a website is only an offering of files that interact with each other, the systems that store and access these data files play an important role in web site general performance.
Hard disk drives, or HDDs, have been, right until the past several years, the most reliable systems for saving information. Then again, lately solid–state drives, or SSDs, are already gaining popularity. Look into our comparison chart to view whether HDDs or SSDs are more appropriate for you.
1. Access Time
With the launch of SSD drives, data access rates have gone tremendous. Thanks to the unique electronic interfaces made use of in SSD drives, the average data file access time has shrunk into a record low of 0.1millisecond.
The concept behind HDD drives dates back to 1954. And even while it has been considerably processed through the years, it’s nonetheless no match for the imaginative technology behind SSD drives. Through today’s HDD drives, the highest data file access rate you can actually reach can vary between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is vital for the effectiveness of any file storage device. We’ve carried out detailed tests and have identified that an SSD can manage at the least 6000 IO’s per second.
Over the exact same lab tests, the HDD drives turned out to be considerably slower, with simply 400 IO operations managed per second. Even though this looks like a significant number, for people with a hectic server that contains numerous sought after web sites, a slow hard drive can cause slow–loading sites.
3. Reliability
SSD drives are made to have as less rotating parts as feasible. They utilize a similar concept like the one found in flash drives and are more dependable as compared to common HDD drives.
SSDs have an typical failing rate of 0.5%.
For an HDD drive to work, it should rotate a couple metal disks at over 7200 rpm, keeping them magnetically stable in the air. They have a good deal of moving components, motors, magnets along with other tools packed in a small space. Consequently it’s obvious why the regular rate of failure of an HDD drive varies among 2% and 5%.
4. Energy Conservation
SSDs don’t have moving parts and need hardly any chilling energy. They also demand very little energy to work – tests have demostrated that they’ll be operated by a standard AA battery.
As a whole, SSDs consume amongst 2 and 5 watts.
As soon as they have been designed, HDDs were always quite electrical power–greedy equipment. So when you’ve got a web server with different HDD drives, it will boost the month–to–month electric bill.
Typically, HDDs use up between 6 and 15 watts.
5. CPU Power
SSD drives allow for swifter data access rates, which, consequently, enable the CPU to complete data file requests considerably quicker and to return to other jobs.
The standard I/O wait for SSD drives is exactly 1%.
When using an HDD, you have to invest extra time waiting around for the results of one’s data file query. This means that the CPU will stay idle for extra time, waiting around for the HDD to reply.
The typical I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
In the real world, SSDs carry out as perfectly as they managed for the duration of Hyper Bee LLC’s testing. We competed a full platform back up on one of our production servers. Throughout the backup operation, the average service time for any I/O queries was indeed under 20 ms.
During the same tests using the same web server, now equipped out utilizing HDDs, functionality was substantially slower. During the web server back up process, the average service time for any I/O requests varied between 400 and 500 ms.
7. Backup Rates
One more real–life advancement is the rate at which the backup is created. With SSDs, a server data backup now can take under 6 hours by using Hyper Bee LLC’s web server–designed software solutions.
On the other hand, on a hosting server with HDD drives, a similar backup usually takes 3 to 4 times as long to finish. An entire backup of an HDD–equipped web server normally takes 20 to 24 hours.
To be able to easily boost the general performance of one’s web sites and not have to alter just about any code, an SSD–powered website hosting solution is a good option.
