SSDs vs HDDs
Assess the 2 industry–leading data storage devices
For years there seemed to be a single dependable solution to keep information on a personal computer – working with a disk drive (HDD). On the other hand, this type of technology is already showing its age – hard drives are actually noisy and slow; they’re power–hungry and tend to create a lot of warmth throughout intensive operations.
SSD drives, alternatively, are extremely fast, consume a smaller amount power and they are far less hot. They provide an innovative method of file access and data storage and are years in advance of HDDs in terms of file read/write speed, I/O operation and energy capability. Discover how HDDs fare against the newer SSD drives.
1. Access Time
With the arrival of SSD drives, file access rates are now over the top. Due to the unique electronic interfaces found in SSD drives, the average data access time has been reduced into a record low of 0.1millisecond.
HDD drives make use of rotating disks for files storage purposes. Each time a file is being accessed, you will need to wait around for the appropriate disk to get to the right position for the laser beam to reach the data file in question. This leads to a regular access rate of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is critical for the operation of any data storage device. We’ve carried out extensive testing and have confirmed that an SSD can handle no less than 6000 IO’s per second.
Hard drives feature reduced data file access rates due to the aging file storage and access technique they’re employing. Additionally they show noticeably sluggish random I/O performance in comparison with SSD drives.
In the course of Fourhman Hosting’s tests, HDD drives addressed typically 400 IO operations per second.
3. Reliability
SSD drives are created to have as fewer moving parts as is possible. They utilize a similar technique like the one employed in flash drives and are generally more efficient when compared to traditional HDD drives.
SSDs provide an common failing rate of 0.5%.
To have an HDD drive to work, it should rotate a pair of metal hard disks at a minimum of 7200 rpm, retaining them magnetically stabilized in the air. They have a lots of moving parts, motors, magnets along with other devices loaded in a small location. Therefore it’s obvious why the normal rate of failing associated with an HDD drive can vary among 2% and 5%.
4. Energy Conservation
SSDs don’t have any moving parts and require little or no cooling energy. Additionally they involve not much power to function – tests have established that they’ll be powered by a normal AA battery.
As a whole, SSDs use up somewhere between 2 and 5 watts.
HDD drives can be well known for being loud; they’re more likely to getting hot and when you have several hard drives in a web server, you need an additional cooling system only for them.
All together, HDDs consume somewhere between 6 and 15 watts.
5. CPU Power
SSD drives enable faster data accessibility speeds, which generally, in return, enable the CPU to complete data requests considerably quicker and afterwards to go back to different responsibilities.
The typical I/O hold out for SSD drives is simply 1%.
HDD drives support reduced accessibility rates than SSDs do, resulting for the CPU having to hold out, although arranging assets for your HDD to locate and give back the demanded file.
The average I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
In the real world, SSDs conduct as perfectly as they have for the duration of Fourhman Hosting’s testing. We competed a full system data backup using one of our own production web servers. Through the backup procedure, the typical service time for I/O calls was under 20 ms.
Sticking with the same web server, but this time built with HDDs, the results were different. The average service time for an I/O query changed between 400 and 500 ms.
7. Backup Rates
Discussing back ups and SSDs – we have witnessed an amazing progress in the back up speed as we turned to SSDs. Today, a standard hosting server data backup can take just 6 hours.
Throughout the years, we have got made use of largely HDD drives on our servers and we’re well aware of their general performance. On a server furnished with HDD drives, a full hosting server back–up typically takes around 20 to 24 hours.
To be able to promptly enhance the general performance of your web sites without the need to transform any kind of code, an SSD–driven website hosting service will be a excellent alternative. Look at the Linux cloud web hosting packages as well as the VPS servers – our services offer quick SSD drives and are available at competitive prices.
