For years there seemed to be just one single reliable way to keep info on a pc – having a disk drive (HDD). Having said that, this type of technology is currently displaying it’s age – hard drives are really noisy and slow; they’re power–ravenous and have a tendency to produce lots of heat throughout serious procedures.
SSD drives, on the contrary, are really fast, use up a smaller amount energy and tend to be much cooler. They offer a whole new method of file access and data storage and are years in front of HDDs when it comes to file read/write speed, I/O efficiency and also power efficiency. Observe how HDDs stand up up against the newer SSD drives.
1. Access Time
Due to a radical new method of disk drive performance, SSD drives permit for considerably faster data accessibility rates. With an SSD, data access instances are far lower (under 0.1 millisecond).
HDD drives make use of rotating disks for data storage purposes. Each time a file is being used, you need to wait around for the correct disk to get to the right position for the laser beam to view the file you want. This ends in a standard access speed of 5 to 8 milliseconds.
2. Random I/O Performance
Due to the new significant data file storage approach incorporated by SSDs, they feature speedier file access rates and speedier random I/O performance.
In the course of our lab tests, all SSDs demonstrated their capacity to handle no less than 6000 IO’s per second.
With an HDD drive, the I/O performance steadily enhances the more you use the disk drive. Nonetheless, in the past it gets to a particular limitation, it can’t go quicker. And due to the now–old technology, that I/O limit is significantly lower than what you can get having an SSD.
HDD are only able to go so far as 400 IO’s per second.
The absence of moving parts and rotating disks inside SSD drives, and the latest advancements in electronic interface technology have generated a considerably less risky data file storage device, having an typical failing rate of 0.5%.
With an HDD drive to function, it needs to rotate a pair of metal hard disks at a minimum of 7200 rpm, having them magnetically stabilized in the air. There is a good deal of moving elements, motors, magnets and also other tools loaded in a small space. So it’s no surprise that the standard rate of failing of the HDD drive ranges somewhere between 2% and 5%.
4. Energy Conservation
SSD drives work virtually silently; they don’t generate extra warmth; they don’t demand additional air conditioning solutions and also use up far less energy.
Tests have demostrated the typical electrical power utilization of an SSD drive is between 2 and 5 watts.
From the minute they were created, HDDs have invariably been really energy–greedy systems. So when you have a hosting server with numerous HDD drives, this will certainly boost the monthly utility bill.
On average, HDDs use up between 6 and 15 watts.
5. CPU Power
SSD drives provide for swifter file accessibility rates, which, consequently, allow the processor to accomplish data file queries considerably faster and afterwards to return to different tasks.
The normal I/O wait for SSD drives is 1%.
When using an HDD, you must dedicate time awaiting the outcome of your data file query. Consequently the CPU will be idle for further time, awaiting the HDD to react.
The standard I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
It’s time for several real–world instances. We, at RedHosting, ran an entire system backup with a hosting server only using SSDs for data storage purposes. During that operation, the regular service time for an I/O request remained under 20 ms.
Weighed against SSD drives, HDDs offer substantially slower service rates for input/output calls. Throughout a web server backup, the regular service time for any I/O request ranges between 400 and 500 ms.
7. Backup Rates
Talking about back–ups and SSDs – we’ve witnessed an exceptional enhancement in the back up rate since we turned to SSDs. Today, a regular web server backup will take solely 6 hours.
Over time, we’ve got used mostly HDD drives with our web servers and we are knowledgeable of their overall performance. With a server pre–loaded with HDD drives, an entire hosting server back–up usually takes around 20 to 24 hours.
