SSDs vs HDDs
Check out the Pro’s and Con’s of HDD and SSD drives
When you have a website or an application, rate of operation is critical. The speedier your site loads and the swifter your web applications perform, the better for everyone. Because a site is only an array of files that connect with one another, the devices that keep and work with these data files have a vital role in web site general performance.
Hard disk drives, or HDDs, have been, right until the past several years, the more effective devices for storing information. Having said that, in recent years solid–state drives, or SSDs, have been gathering popularity. Take a look at our evaluation chart to find out if HDDs or SSDs are more appropriate for you.
1. Access Time
With the introduction of SSD drives, file accessibility speeds have gone through the roof. As a result of completely new electronic interfaces found in SSD drives, the common file access time has been reduced into a all–time low of 0.1millisecond.
HDD drives continue to take advantage of the same basic data file access concept that was originally created in the 1950s. Though it has been substantially advanced consequently, it’s sluggish when compared to what SSDs will offer. HDD drives’ file access rate varies in between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is extremely important for the operation of any data storage device. We’ve executed substantial testing and have established that an SSD can deal with at the least 6000 IO’s per second.
Hard drives feature reduced data access rates as a result of aging file storage and access technique they’re employing. Additionally they display noticeably slower random I/O performance compared with SSD drives.
In the course of our tests, HDD drives dealt with on average 400 IO operations per second.
3. Reliability
The absence of moving parts and spinning disks in SSD drives, as well as the recent improvements in electrical interface technology have generated a considerably better data file storage device, with a common failure rate of 0.5%.
HDD drives implement rotating hard disks for storing and reading files – a concept since the 1950s. With hard disks magnetically hanging in mid–air, rotating at 7200 rpm, the prospects of anything going wrong are usually bigger.
The standard rate of failing of HDD drives can vary between 2% and 5%.
4. Energy Conservation
SSD drives are far smaller compared to HDD drives as well as they don’t have virtually any moving components at all. As a result they don’t make as much heat and require less power to operate and much less power for chilling reasons.
SSDs consume somewhere between 2 and 5 watts.
From the second they have been built, HDDs have been very electric power–ravenous equipment. And when you’ve got a server with many different HDD drives, this will certainly increase the regular monthly power bill.
On average, HDDs consume somewhere between 6 and 15 watts.
5. CPU Power
Because of SSD drives’ better I/O functionality, the key web server CPU can easily work with file requests a lot quicker and save time for different functions.
The standard I/O delay for SSD drives is just 1%.
When using an HDD, you need to dedicate time anticipating the outcome of one’s data file query. This means that the CPU will remain idle for extra time, looking forward to the HDD to reply.
The common I/O delay for HDD drives is about 7%.
6.Input/Output Request Times
Almost all of Sure Link’s new servers are now using solely SSD drives. All of our lab tests have established that utilizing an SSD, the typical service time for any I/O request whilst performing a backup remains below 20 ms.
Using the same web server, yet this time loaded with HDDs, the end results were very different. The average service time for any I/O request fluctuated between 400 and 500 ms.
7. Backup Rates
You’ll be able to feel the real–world great things about having SSD drives every single day. For example, on a hosting server loaded with SSD drives, a full data backup is going to take merely 6 hours.
In the past, we have used principally HDD drives on our servers and we are familiar with their overall performance. With a hosting server pre–loaded with HDD drives, a full web server data backup often takes around 20 to 24 hours.
Our Linux VPS hosting plus our typical Linux shared website hosting accounts have SSD drives automatically. Join our Sure Link family, to see the way we may help you supercharge your website.
