For years there was only one trustworthy option to store data on your computer – by using a disk drive (HDD). Nevertheless, this type of technology is presently showing it’s age – hard disk drives are loud and sluggish; they can be power–hungry and frequently produce quite a lot of heat during intensive procedures.
SSD drives, alternatively, are really fast, use up significantly less power and are much cooler. They furnish a new way of file access and data storage and are years ahead of HDDs with regard to file read/write speed, I/O performance and also energy capability. Find out how HDDs stand up up against the modern SSD drives.
1. Access Time
Because of a revolutionary new solution to disk drive general performance, SSD drives enable for considerably faster data file access speeds. Having an SSD, file access times are much lower (as small as 0.1 millisecond).
HDD drives depend on spinning disks for data storage purposes. When a file will be utilized, you will have to wait around for the right disk to get to the right place for the laser to view the data file in question. This results in a typical access rate of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is very important for the performance of any file storage device. We have run substantial lab tests and have established an SSD can manage at the very least 6000 IO’s per second.
With a HDD drive, the I/O performance gradually improves the more you use the disk drive. Nevertheless, right after it actually reaches a specific cap, it can’t go faster. And due to the now–old technology, that I/O restriction is significantly less than what you might receive with a SSD.
HDD are only able to go so far as 400 IO’s per second.
The lack of moving elements and spinning disks inside SSD drives, and the recent advancements in electrical interface technology have generated a substantially safer data storage device, having an typical failure rate of 0.5%.
Since we have previously mentioned, HDD drives rely on rotating hard disks. And something that makes use of lots of moving elements for prolonged intervals is at risk from failure.
HDD drives’ typical rate of failing can vary among 2% and 5%.
4. Energy Conservation
SSD drives work practically noiselessly; they don’t generate surplus warmth; they don’t demand additional air conditioning solutions as well as consume a lot less energy.
Lab tests have demonstrated the normal electrical power intake of an SSD drive is between 2 and 5 watts.
From the second they have been made, HDDs have invariably been really electrical power–hungry systems. So when you have a server with a couple of HDD drives, this can boost the month–to–month utility bill.
On average, HDDs consume somewhere between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ better I/O efficiency, the key server CPU can easily work with data file queries faster and preserve time for different operations.
The normal I/O delay for SSD drives is only 1%.
By using an HDD, you will have to invest time waiting around for the outcome of one’s data file query. It means that the CPU will be idle for further time, expecting the HDD to react.
The typical I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
In the real world, SSDs carry out as admirably as they did during the trials. We competed a complete platform back–up using one of our own production web servers. All through the backup process, the normal service time for any I/O requests was in fact under 20 ms.
In contrast to SSD drives, HDDs provide considerably slower service times for I/O queries. During a server backup, the normal service time for an I/O request varies somewhere between 400 and 500 ms.
7. Backup Rates
Talking about back–ups and SSDs – we’ve detected an exceptional development with the data backup speed as we moved to SSDs. Now, a normal web server backup takes solely 6 hours.
Alternatively, with a hosting server with HDD drives, a comparable back–up may take 3 to 4 times as long in order to complete. An entire back–up of any HDD–powered hosting server typically takes 20 to 24 hours.
