SSDs vs HDDs
Do a comparison of the two industry–leading data storage space devices
For many years there seemed to be one reliable way for you to keep information on your computer – utilizing a hard drive (HDD). On the other hand, this kind of technology is by now expressing it’s age – hard disk drives are loud and slow; they’re power–ravenous and tend to create quite a lot of warmth during intense procedures.
SSD drives, however, are really fast, take in a lesser amount of energy and they are much cooler. They provide a completely new method to file accessibility and data storage and are years in advance of HDDs when it comes to file read/write speed, I/O efficiency as well as power efficacy. Discover how HDDs stand up against the more recent SSD drives.
1. Access Time
With the launch of SSD drives, file accessibility speeds are now tremendous. Thanks to the brand–new electronic interfaces used in SSD drives, the average data file access time has been reduced to a record low of 0.1millisecond.
The technology powering HDD drives times back to 1954. And even though it’s been significantly refined over the years, it’s even now can’t stand up to the ground breaking ideas behind SSD drives. Through today’s HDD drives, the highest file access rate you’re able to achieve may differ somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Because of the brand–new revolutionary data file storage technique embraced by SSDs, they offer better file access speeds and faster random I/O performance.
In the course of Kanbes IT Solutions’s lab tests, all SSDs confirmed their capacity to handle at least 6000 IO’s per second.
Hard drives present reduced data access speeds due to older file storage and access technology they are implementing. And they also demonstrate noticeably slower random I/O performance as compared to SSD drives.
During Kanbes IT Solutions’s lab tests, HDD drives managed an average of 400 IO operations per second.
3. Reliability
The lack of moving parts and spinning disks in SSD drives, and also the current advancements in electronic interface technology have generated an extremely better file storage device, having a typical failure rate of 0.5%.
With an HDD drive to function, it must rotate 2 metallic disks at a minimum of 7200 rpm, retaining them magnetically stabilized in mid–air. There is a whole lot of moving components, motors, magnets and also other devices crammed in a tiny place. Consequently it’s no surprise the average rate of failure of an HDD drive can vary in between 2% and 5%.
4. Energy Conservation
SSDs don’t have any moving parts and need hardly any chilling power. In addition they call for not much energy to perform – trials have revealed that they’ll be powered by a normal AA battery.
In general, SSDs consume amongst 2 and 5 watts.
HDD drives are famous for becoming noisy. They require far more energy for cooling down applications. With a hosting server which includes several HDDs running all the time, you need a lot of fans to make sure they’re cooler – this makes them much less energy–economical than SSD drives.
HDDs take in somewhere between 6 and 15 watts.
5. CPU Power
The speedier the data access speed is, the quicker the file demands will be treated. As a result the CPU won’t have to reserve assets looking forward to the SSD to respond back.
The average I/O wait for SSD drives is actually 1%.
As compared to SSDs, HDDs allow for not so quick data access speeds. The CPU will be required to lose time waiting for the HDD to return the required data, scheduling its resources for the time being.
The common I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
Almost all of our new servers moved to simply SSD drives. Our very own lab tests have indicated that by using an SSD, the normal service time for any I/O request although operating a backup stays below 20 ms.
With the exact same server, but this time furnished with HDDs, the end results were different. The regular service time for any I/O query changed between 400 and 500 ms.
7. Backup Rates
Speaking about back ups and SSDs – we have found an effective improvement with the data backup rate as we turned to SSDs. Today, a regular server data backup will take merely 6 hours.
We utilized HDDs exclusively for quite a while and we have got pretty good expertise in just how an HDD works. Generating a backup for a hosting server furnished with HDD drives will take around 20 to 24 hours.
To be able to immediately add to the performance of your sites and never have to transform any code, an SSD–equipped website hosting service will be a great solution. Check out the Linux cloud hosting packages – our solutions feature swift SSD drives and can be found at good prices.
