For decades there was just one single reliable way to keep info on your computer – having a disk drive (HDD). However, this type of technology is by now showing it’s age – hard drives are noisy and sluggish; they can be power–hungry and are likely to create lots of warmth throughout serious procedures.
SSD drives, on the contrary, are quick, use up much less power and are also far less hot. They provide a completely new approach to file access and data storage and are years in front of HDDs with regards to file read/write speed, I/O performance as well as power effectivity. Discover how HDDs fare against the newer SSD drives.
1. Access Time
After the release of SSD drives, file accessibility speeds have gone through the roof. With thanks to the completely new electronic interfaces used in SSD drives, the standard data access time has been reduced to a record low of 0.1millisecond.
HDD drives count on rotating disks for files storage uses. When a file is being used, you have to await the correct disk to get to the appropriate place for the laser beam to access the data file you want. This translates into a common access rate of 5 to 8 milliseconds.
2. Random I/O Performance
On account of the very same radical approach which enables for better access times, it is possible to get pleasure from improved I/O effectiveness with SSD drives. They can carry out two times as many procedures during a given time as opposed to an HDD drive.
An SSD can handle at least 6000 IO’s per second.
All through the exact same tests, the HDD drives proved to be significantly slower, with simply 400 IO operations managed per second. While this may appear to be a great number, for those who have a hectic web server that serves many sought after web sites, a slow disk drive may result in slow–loading websites.
The absence of moving components and spinning disks in SSD drives, as well as the recent improvements in electrical interface technology have generated a much risk–free file storage device, having an typical failure rate of 0.5%.
With an HDD drive to operate, it needs to spin a pair of metal hard disks at more than 7200 rpm, holding them magnetically stable in mid–air. There is a whole lot of moving components, motors, magnets and other tools loaded in a tiny location. Hence it’s no surprise the average rate of failure of an HDD drive can vary between 2% and 5%.
4. Energy Conservation
SSD drives operate nearly silently; they don’t make excess warmth; they don’t require extra chilling methods and use up less energy.
Lab tests have established the typical electrical power usage of an SSD drive is amongst 2 and 5 watts.
From the time they were developed, HDDs have always been really electrical power–greedy equipment. When you’ve got a hosting server with several HDD drives, this will increase the monthly electricity bill.
Typically, HDDs consume between 6 and 15 watts.
5. CPU Power
The speedier the data access speed is, the sooner the file calls can be handled. Therefore the CPU will not have to reserve allocations expecting the SSD to reply back.
The average I/O wait for SSD drives is barely 1%.
By using an HDD, you’ll have to dedicate time anticipating the outcomes of your file ask. This means that the CPU will remain idle for more time, waiting for the HDD to respond.
The typical I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
The vast majority of our brand new web servers are now using exclusively SSD drives. All of our tests have indicated that with an SSD, the typical service time for an I/O request although running a backup remains below 20 ms.
With the exact same hosting server, yet this time equipped with HDDs, the end results were completely different. The standard service time for an I/O request changed somewhere between 400 and 500 ms.
7. Backup Rates
You are able to check out the real–world great things about utilizing SSD drives day by day. For instance, with a hosting server built with SSD drives, a full back up can take merely 6 hours.
Throughout the years, we’ve made use of principally HDD drives on our web servers and we’re well aware of their performance. With a web server pre–loaded with HDD drives, a complete hosting server back up usually takes about 20 to 24 hours.
Should you wish to promptly boost the efficiency of your respective websites while not having to alter any code, an SSD–equipped website hosting solution will be a very good alternative. Look at Orihost.com’s Linux shared web hosting services packages and additionally our VPS – these hosting services feature extremely fast SSD drives and are offered at the best prices.
