For many years there was only one efficient way for you to store information on a pc – working with a hard disk drive (HDD). Then again, this type of technology is currently showing it’s age – hard disks are actually noisy and sluggish; they are power–hungry and have a tendency to produce quite a lot of heat in the course of serious operations.
SSD drives, however, are extremely fast, consume a smaller amount power and tend to be far less hot. They feature an innovative approach to file access and data storage and are years ahead of HDDs in relation to file read/write speed, I/O performance and then power efficiency. See how HDDs fare against the newer SSD drives.
1. Access Time
After the introduction of SSD drives, file accessibility rates have gone over the top. Due to the unique electronic interfaces used in SSD drives, the typical data access time has been reduced to a all–time low of 0.1millisecond.
HDD drives still makes use of the same fundamental file access concept that was initially developed in the 1950s. Though it has been noticeably upgraded after that, it’s slow in comparison to what SSDs are providing. HDD drives’ data file access speed can vary in between 5 and 8 milliseconds.
2. Random I/O Performance
Thanks to the very same radical technique that enables for quicker access times, it is possible to experience improved I/O efficiency with SSD drives. They are able to perform two times as many procedures throughout a given time as compared with an HDD drive.
An SSD can manage at the least 6000 IO’s per second.
With an HDD drive, the I/O performance gradually raises the more you use the drive. However, just after it extends to a particular limit, it can’t go speedier. And because of the now–old concept, that I/O restriction is significantly below what you can have with a SSD.
HDD are only able to go as much as 400 IO’s per second.
SSD drives lack any kind of moving parts, which means that there is significantly less machinery included. And the fewer physically moving parts there are, the lower the probability of failing can be.
The normal rate of failing of an SSD drive is 0.5%.
To have an HDD drive to function, it has to rotate two metal disks at over 7200 rpm, having them magnetically stable in the air. There is a great number of moving components, motors, magnets as well as other tools jammed in a tiny location. So it’s no surprise that the common rate of failure of an HDD drive varies between 2% and 5%.
4. Energy Conservation
SSD drives are considerably smaller compared to HDD drives and they don’t have just about any moving components at all. It means that they don’t produce as much heat and need less electricity to function and much less energy for cooling reasons.
SSDs consume somewhere between 2 and 5 watts.
HDD drives are renowned for staying noisy. They require a lot more electric power for cooling down reasons. With a server that has a range of HDDs running at all times, you will need a lot of fans to ensure that they’re kept cool – this will make them much less energy–economical than SSD drives.
HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ higher I/O effectiveness, the leading hosting server CPU will be able to work with file calls more rapidly and preserve time for other operations.
The regular I/O delay for SSD drives is just 1%.
As compared with SSDs, HDDs enable slower data accessibility speeds. The CPU will be required to lose time waiting for the HDD to return the requested data, scheduling its assets in the meanwhile.
The common I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
Almost all of ManifestHosting.com’s new web servers are now using merely SSD drives. Each of our lab tests have established that having an SSD, the common service time for an I/O request while operating a backup continues to be under 20 ms.
Compared with SSD drives, HDDs deliver noticeably reduced service rates for input/output demands. During a server backup, the standard service time for any I/O query ranges between 400 and 500 ms.
7. Backup Rates
One more real–life enhancement is the speed at which the back–up was produced. With SSDs, a web server data backup currently takes under 6 hours by using ManifestHosting.com’s web server–enhanced software solutions.
In the past, we’ve employed mainly HDD drives with our machines and we’re well aware of their efficiency. With a web server pre–loaded with HDD drives, an entire hosting server data backup will take around 20 to 24 hours.
Our Linux cloud web hosting accounts offer SSD drives automatically. Be a part of our ManifestHosting.com family, and discover the way we can help you help your site.
